TRANSCRIPT

So draft an RPM mode. Once you've established your draft, you can hold down the pressure mode button and switch back to pressure where it does everything for you. Matter of fact, you can switch back and forth at any time. If I'm pumping three or four hand lines on here and I look and I see I'm in RPM mode, just hold the pressure mode button down right then and switch over.

Cuz at the point you're switching, you're at a set pressure and a set rpm, right? So it just moves over. Pressure mode. You don't have to add 'em down or nothing like that. You do the switch back and forth. One more thing. If you ever get back here, put it in its impression mode and you can't get pressure, you see some message you've never seen in that little window on the bottom.

On this one, it'll say, no interlock. You see that? No interlock as telling you your pressure. Governor's not communicating with your engine. That transducer goes out, which is, it can. It's just like any other part on this fire, on this fire truck. If it goes out, it's gonna say no. If it's me, I'd go straight to RPM mode.

If I get pressure in RPM mode, I fight that fire in RPM mode until I get it fixed. All right, let me, I'm gonna tell you why I just went through all this. All we were ever taught about these things was pop in pressure, drafted RRP m, and in the end, that's what you're going to do pretty much, right? Well, the fire station I work at, we had a captain and a rookie firefighter die in a house fire.

It was the rookie second day on the job, first fire, and Captain Harlow had made many fires with him. Good fire. Actually, I was working an overtime shift at another station and I heard the box come in for my record station, one story house. It turns out as a one story house fire. Captain Harlow went on location, smoking, fire, showing from one story, making a fast attack.

At that time, everything we did was a fast attack, whatever we, whether one room burning, the whole name thing burning is a fast attack. Just what we said, right? Mm-hmm. It's a little different now, but anyway. Captain Harlow, this house set on a bayou. And so the back of the house was all by you and green and the city if you could take advantage of the green, you know, so the whole back of the house was glass to no back neighbors.

Right? But we had the northern bro blowing in and it was blowing into the back of the house. They went in the front door and then uh, at some point that glass felled due to heat and it was like a torch come across. If you read the line of duty death report from NA and the. The big thing they talked about, that was the fire that started the missed wind driven fire study.

That's the one that's mentioned in the wind, if y'all have ever read that wind driven fire stuff, right. Flow paths and all that. Mm-hmm. That, that's mentioned in there. That fire. But in a, in a, not the death reports, the, uh, fatality reports. They talk about wind drift fire. Right. And also they didn't like where we cut.

We cut holes in. Well, if we could get it, if we could get on the roof and cut a hole, we'd cut a hole. And, uh, but that does accelerate burning. If you cut a hole on the roof, it's gonna accelerate burning. It's as simple as that. Cause the whole flow path thing, right? But it allows you to get in there and put it out quicker, a lot easier.

So they hit us on that. But what you want read in the reports is what happened at the prompt. Found the guy driving engine 26 that night was a truck. Our trucks have no ladder pipes. Every time he comes to work, he works on ladder truck without a pump. He was working an extra shift on the engine and he knew what everybody knows.

Pump and pressure gaff and rpm. That's all we need to know. Right. Well, when he went from tank water to Hyner water, he introduced air to the pump, to the supply line. RPMs went out the roof, sent the engine out. Detective Pump did exactly what it's supposed to, but nobody was aware that it was supposed to happen.

He thought the firetruck broke down. It was an FRC pressure gun, and at that time he'd kicked you out your remote. So the whole time water highway pressure pushes the arrow out, the water's back, right? But. They're still in there without anything cause he never hit the motor button and reestablished the pressure.

Now that guy come up to the pump panel, seen it wasn't in the mold, hit the pressure button, fixed the water problem. Captain Atar was on the second line in that fire. He said when they lost the pressure, you could close the noles of the hose would get hard. But when you opened it up just there, what's your high brushes 60.

So that's because the pump was sitting in Ile, right? It had pushed the air on through. Just waiting on that. So the reason I go through this is because if it happens to you, you know it's supposed to happen. It did exactly what it's supposed to, and that's up to you to fix it. I'll give you another example.

You could do everything right and still have this happen to you. We're in a warehouse fire, and this warehouse was a city blocked. It is a furniture manufacturing place where they brought in the raw material, made the furniture stored to Finishment furniture until it was shipped out, right? Mm-hmm. This Christmas day, we had fire coming through the roof, so we had inches seven supply and ladder seven.

Had a ground monitor in there and, and, and crew inside on two and a half inch can lines, cause it's starts such a large building, we could actually have crews inside and ladder, pipe going, which, you know, you don't do on a normal building, but this would big. And so everything was fine until they set up. I seen another lighter pipe come up on the other side of the building.

As soon as I seen the water coming outta the ladder pipe, I heard engine sevens, RPMs go out the roof and. What just happened? They robb the water, right? They got on the same main once they started that ladder pipe, but changed what he had coming in. If you're trying a ladder seven, what do you do right now?

Fuck out. Shut down the ladder. Pipe Shut down that ground monitor cuz they're unmanned. Get that hand line water back, right? Cuz they're inside so that they can protect themselves. Here's my point on that. You cannot change what's coming in right now. You can only change what's going out to fix this product.

If I got 500 gallon a minute coming into the intake side of my pump, how big my pump. 500 a minute. I don't care what that tag said earlier. You know your pump is only as big as the amount of water coming into it. That's all you got to work with right now. So I'm gonna use that water to bed. I mean, I'm gonna change what I did.

I'm gonna get the hand line there. Water pipe. Now we can go and fix the problem. But right now you, that's the only way of course you get on the radio, tell you lost your supply. Wonder if you got guys on the hand lines shut down. Anything that might not, you know, if you got a guy protected with exposure on the handline and one inside, you know, shut that down and get, get that water back until you fix your problem.

I'll give you a more example. I mean, I've got several examples. The El Paso fire Department put five engines out of service cuz they kept shutting down on fires and guys just refused to work on 'em anymore, right? We couldn't find nothing wrong with 'em. Every mechanics didn't find nothing wrong with 'em.

So I went to El Paso to see if we, what it is, well we'll figure out, right? I went through this whole class with five crews sitting in one room and nobody said a word when I talked about impression. Well, I said, all right, let's go out and you know, once we finish, finish inside, we're gonna go out there and run your truck.

So we start on tank water like any fire. And I said, okay, open the hide. This kid said, Hey, you need to open your intake valve first. I said, why is that? He said, cause. Valves are easier open if there's not water against them. That's how we do it here. What happens in Take Valve before I open the Hyran? You can't get rid of there.

It has to go through the pump. It's gonna shut you down every time. Right. And uh, actually I was just in El Paso a couple weeks ago and I told that a story and I may walk out mad. He said, we don't do like that. I didn't make the story off cap and I didn't, and this other guy said I was there for the classes exactly what happened.

You know they've changed, right? But that's the way they did. If you ever worked on a firetruck, they had to know big old butterfly valves. You know, they had a little cl we had, they were hard tank to open with water. We used to have, our mayor had shut down all our PRVs, so we have hydrants that had 200 psi and one little click.

You couldn't just open that garage. You went one click, man. It was just about the, the ground. So that's, That's where they come from and they just carried that on through, right? Mm-hmm. And uh, then they never change when they change the types of valves they have, the bald valves or gate valves or whatever the policy state.

Same until Yeah, they fix until their trucks work down. Yeah. All. All right. So my stories, and I don't like to be puzzled cause the family does not know what happened on the compound. Engine 26. The only reason we know what happened, Every, when we have a line of duty, death, everybody on Fireground has to write a statement and the guy who walked up to the pump panel put it back in pressure mold.

That, that's how we figured out what happened. And then we took Engine 26 and we did debate it over and over and over, and it did shut down every time he introduced Aaron to the, you know, to a supply line. Because after that, did FRC change the program to go back to his last set of pressure? Whether or not it was about that fire or not?

I don't know, but I know we talked to FRC after that. I did personally, about how they shut down and, and they ended up changing. To go back to this last set of pressure, class one is still the same. They'll still on the rby. If you cavitated it and it shuts. You have to reestablish the pressure yourself.

Cause that it's got fall off wipe fall off. Yeah. That not change anymore. Leak. Yeah. Good. So anyway, we'll move on. Fillings fall off. All right. Intake a discharge gauge just like we've always had. I like that. Discharge charge thousand gauges. They're all labeled color. If it's got red and white tag foam will come up out of it.

If it's got black and silver, you're not going to get any foam out of, so on your cross legs, you got your number one cross that has foam. Your number two cross doesn't have foam. And then I think you got a two and a half inch cross lay that has fall. And I can just tell by looking at the tag without even reading what's on.

Do the number two cross your large downward discharge? It's got a needle valve in the middle that shows you the position of the water valve all the way open. Halfway open. Cool. Alright. Tank field research lining. Tank the pump. You got a 1500 gallon per minute pump. That's a large pump. Large pump's overheat quickly.

Soon as your pump goes in gear, you need some water to the pump. Your first source of water is your tanks, so you open the tank to pump. That's good for a minute or two, but if you don't start flowing some water or circulating some water, that same water will turn in that pump overheat and damage your pump just as if you have no water.

So we teach the circulating water by cracking your tank. Feel recirc research. When I say crack it, I just open it enough. I feel water move through the valve. That's good enough to keep my. Anything more than that, I start robbing available water from the fire ground. I said earlier, people cavitate their pump with that valve alone.

Your tank filled er line is an inch and a half pipe that goes from the discharge side of your pump right into your tank to fill it up. An inch and a half tip on a ladder pipe will flow over 600 gallons a. So obviously an inch and half pipe could flow 600 gallons a minute. So let's say you're in an apartment complex on a dead end hydrant that's given you a thousand gallons a minute, and you're flowing 500 gallons a minute on a fire ground, and you go from tank water to hydrant water.

Once you're on the hydrant, you decide you want to refill your tank, so you open your tank, fills out. You just open a valve that will flow over 600 gallons a minute. If you're already putting 500 gallons a minute out and you only got a thousand coming in, you have tear your pump. That tank field research line is nothing more than a large diamond discharge going into your pump, I mean, into your tank.

It's like opening a deck up, you know, uh, it's just a large diameter discharge, so you have to account for it like every other discharge you opened. You tank the pump. All your pump operating books are gonna tell you when you go from tanked water to hydrant water to closing. When I say hydrant water, I'm talking about a positive water source, right?

Whether it's through tender or a hydrant, it's a positive water source when you go from tank water to HYT water. The books tell you to close your tank of pump. You could do that, but it's not necessary. There is a clapper valve built in there now that used to didn't have before the clapper valve. If you didn't close your tank of pump, whatever water wasn't going outta your discharges, would back up through your tank of pump, fill up your tank.

Li to go up and flood your whole bed, right? Mm-hmm. Now, what happens when you open your intake valve and water pressure comes in? It closes a clapper valve. It's just like if you close that valve yourself, no water is going to back up through to your tank. The only way you're gonna get water in your tank is through your tank filled valve.

Here's the benefit I see in leaving the tank that pop open. Every fire starts on tank water and builds from there, and then you go to a supply line nine on the supply line. I could walk away from that compound. I'll go take care of something and then somebody comes by and takes out my supply. Or if I lose it for whatever reason, if the tanks to pump is shut, like the books say what happens to them guys on the nozzle?

When you lose your supply, lose the water at the same time. If that's open and I'll lost my supply, what would happen?

Right back in tank water, you have however much tank water you have. At least you have some time to warm. Then you lost your. Because when you lose the income of pressure, clapper valve back opens back up that how would you know you lost your supply not to pump out the engine. RPMs are gonna go back to where you're at because when you're introduced that pressure, they always come down.

Anytime you hear a sudden increase in engine RP while you're pumping, you better go look at your supply light. Something change with your supply. If you lost your supply, what would be the first thing you'd want to do? Step on your hose. What's that? Yeah, well one, let 'em know you lost your supply. But the other thing, close your intake because whatever water now, once you lost your supply, whatever tank water you have left will go back up through that open intake valve and and tell you.

Re uh, fix the supply line.

Alright, engine cooler. A lot of people believe you should open the engine cooler every time you pump. That makes no sense to me. If I'm pumping on a fire and my engines at normal operate temperature, why do I want to cool it down? They call it normal for a reason. That's where it ought to be. And then if it starts to overheat, then I have something to fall back on right?

Then I'd open my engine cooler. Hopefully that would cool my engine and get me through there. If it's already open and your engine starts to overheat, you're done. You need to look at shutting it down. How often do you really see these new engines overheat on something like, well, a huge problem already.

It is a problem, actually, believe it or not, with the, the whole, uh, emissions and the of the ERG valve will cause your engine over. I got some pictures of my phone and on pressure governors that I walked up to pump panels at work with the, the, uh, engine temperature, spiked out the roof with the buzzer going off and said, Hey, what's wrong with your fire cut?

And he said, well, the pump's overheating. I said, that's your engine. Overheat. Both times it had to do something with that ERG valve and they caused it the engine to overheat. Mm-hmm. But I don't even know that that's gonna stop it when that happens. So when you open. All that does is allows water to come from your palm from the tank through tubing.

Through tubing that cooling it, just through conduction the cold water going through the, the lower edge tension. Yeah. It doesn't mix it. It's the old fashioned one used to mix it. Is that something you had to drain in the wintertime then, sir? Is that something you had to drain in the wintertime? No, it. Is your parking it outside?

Yeah, I don't think so. So I will say this. This valve needs a big exercise, like every valve on this fire truck. If not, it's gonna be stuck when you need it. Everybody's working on fire trucks with stuck valves cause it's the one we never use. So once a week or so, when you put the pumping gear, open that up, let some water flush through it, close it back, and, and, and keep this bow like every valve should be exercised at least once a week.

So they'll be ready to go when you need it. Your tank level gauge. Light turns full or green. I guarantee you, with a 750 gallon tank, you'll put a lot more water in there before you're actually full. I fill it up until it overflows. That way I know I have a full tank. Your primer is an air primer. Before air primers, we had electric primers.

Before that we had these oil tank primers, right? The electric primers. That tag would say, do not operate for more than a minute, because if you did, you'd burn up that electric motor. This one here says you need to operate it in at least a thousand RPMs. That's so the. The compression that supplies the air while you're priming needs to run at a thousand rpm.

If you hit it with on low RPMs, a lot of times you'll hear that compressor knocking cuz it's not getting the right RPMs to develop the air that it should be. So you should delete drafted at least a thousand rpm. Now yesterday, they couldn't believe how quiet this is. Because I guess y'all had some primers.

Retrofitted with air primers and they can reel out or knock. These are quiet. They're electric. Electric. That's just what the guys told me yesterday. Tomorrow drain valves, and then you got your pump drain. This is kind of one stop drain. Everything with the pump, if I open it up, it's gonna drain the pump, the manifold, and the piping that where it goes in and out of the pump.

Kind one, stop, drain everything with the pump Right below that handle says, do not open or close under pressure. It's a plunger type design that when there's pressure on the pump, there's pressure on the pl. If you move it with the pressure on the plunger, it will break the mechanism. That's why we've only opened this with the pump outta gear.

And no pressure on the pump panel lights is the only electric suite you really have on the uh, pump panel. Just keep in mind when you turn that on, it's gonna turn the panel lights on all of 'em, but one, there should be one that only comes on with the pumping gauge. This will turn the wrist up on. You have a two and a half inch aux, two and a half inch auxiliary intake straight into the pump.

And of course you master intake valve right above your intake relief valve. Protects the intakes out of the pump. If somebody's pumping into you and they pump a pressure higher than your intake relief valve set at, it opens up, starts dumping water under the ground and intake side your palm. I believe.

When I read your spec, you said you had your set at one 50. So anything more than that coming into the intake outta your pump, they should open up. Of course they're adjustable by that nut, but I think you had your specac set at one 50. All right, let's take a what? 10 to 15 minute break and we'll come back and finish up.

How is for like two days,

write him off probation. Hey. Will you turn that on? You can.

The air dump doesn't ambulance. Good. Opposite sticks. Opposite. It's

likes. That's the Husky three control head. And then you got a foam level gauge. Two of your cross lays out. Three have foam front bumper discharge in the rear two and a. You start with water. They say you fire with water along, you take a drop of water. 20% of the drop of water could go to firefighter, 80% could run off.

If you add class A foam to that water, you could change that number around where 80% of the drop of water is effective. With 20% running off class, a phone changes the surface tension of the water. If. You change the surface 10 to of the water, then it stays there longer. If it stays there longer, absorbed more heat, and we put fires out by absorbing heat.

That's why most people put a class, A system on their fire truck. Starting at the top of the tank, whatever foam you put in that tank, we're gonna call that your primary agent, as long as you're only pumping your primary agent. Once you're done, you just turn it off flow water till you have clear water coming out.

The foam pumping the foam pump manifold are designed to be wet with foam at all time. However, you're piping hose and nozzles, not class a. Class A home has an affinity for, for carbon. It attaches itself to carbon. So if you allowed to sit in a piping hose and nozzle, it's gonna start any lubricants in your valves that does away with those, the seals in your valves and starts eating way out.

You got plastic parts in your nozzle, starts eating way at that stuff. You end up with a big maintenance problem. So each time you've. You just turn it off and flush. Uh, keep on flowing water too. We have a clear water coming out. Now if I pump something other than my primary agent, I'm have to flush the pump manifold and everything and we'll go, we'll go through that as we go through this.

The Husky three foam pump is a pi and tight pump that injects on the discharge side of the pump. So associated with the pump is your flow meter. Associated with the flow meter is a foam proportion device that injects foam at the rate the flow meters turn. So for example, when we turn years on, it's going to default to half percent if I don't change anything.

If I start flowing a hundred gallons per minute outta one line and 400 gallons per minute outta the other line, you're both going get a half percent. That's because all your discharges that have a foam come off of one manifold where that flow meter is. Yes. So however much waters go through the flow meter, that's how much foam and injects right to give the same percentage to all your different discharges.

That pump runs by hydraulic fluid. The cooling of the hydraulic fluid is actually the, uh, Husky three system is independent of the water system, so it actually has its own hydraulic oil cooling system up on top, which you'll see. Lego. Let's see, what else before we move on? Our truck is top of one tank.

What's that? Just class A foam, is that right? Yeah. You only have one tank, right? A 20 gallon. Actually the Husky three, the size of the pump, and you'll see as we go through here, this was made, this pump was built for class A foam class. A pump foam is pumped from 0.1 to 1%. When you get talking about flowing class B foam, it's normally flowed from three to 6%.

Depending on what kind of beef foam you buy, there's normally 3% hydrocarbons, 6% polar sauces, and the Husky three pump is just not big enough. It don't flow beef on just a little, like it'll flow eight, but very little, not enough to get you there. Yeah, and we'll talk about that as we go through. So it's uh, it is as easy as turning it on.

If I'm flowing water already, I'm gonna discharge that foam capable and I turning it on. That flow meter is already turning this, it is gonna start injecting foam as soon as you turn it on. And like I said, once again, once you done, just turn it off flow water till you have clear water coming out. The increase in decrease buttons, change foam percentage.

Or we use the decrease button to put it in fo uh, fill mode. You'll see that as we go through Prime. If I hold the prime button down, it just takes the pump and works at full capacity, right? Once your foam pump is primed, it should stay primed cuz it's designed to be wet all the time unless you run it dry or drain it right?

So we'll use the prime button to prime it, but you can also use the prime button to speed things along. So every time we use it, once we're done, we flush it. Uh uh, piping holes and nozzle, right? Every fire starts with one line and build From there they say, give me foam. I'll pull that one line up and I turn it on at a half percent.

That pump is not working very hard to supply the half percent for that one inch three quarter line. So it takes a little bit for the piping hose and nozzle. Before you actually see it come out the nozzle. If I wanna see it quicker, I just hit the prime button for about three or four seconds. I take the pump from moving this fast to like a little bit line up real quick.

It's just, you'll see the foam quicker that way. Right? All right. The most important thing about the prime button, if I go out there and turn it on right now and hold the prime button down, it's a closed system that pump's gonna start pumping. It's gonna build up pressure until something gives you gonna blow the seals outta that pump a connection or so a connection or something.

There's no relief valve to protect you from over pressurizing that pump. So the only time you ever hold a prime button down is if you're already discharged, your water on phone, capable discharge, or you open your phone pump discharge. Okay. Which you'll see as we go through here. If I open a discharge drain, that's an opening on the discharge side of the pump, you'll let that pressure go out the drain.

You got three system status lights. I know you can't see 'em in there. There's three little L e D lights. The top one's green. It has a solid green light. The foam system's on a blinking green light. It should be injecting foam water's flowing. The next one is a red. A blinking red lamp like you'll see today is any time you're less than a quarter tank of, uh, your low on foam, you're gonna get a blinking red lamp.

A solid red lamp says there's a valve in the wrong position for what you're trying to do. The bottom one is a yellow lamp. When I put it in fill mode and I'm refilling the tank using the phone pump the whole time, it's filling the yellow ice blinking. Once the tank is full, there's a float switch that shuts off the pump.

When it shuts out, you one, you're gonna hear the top quit running, but two, the yellow light will quick blinking when you're full. Uh, when I hold the prime button down, there's a solid yellow app for whatever reason. It just shows you're holding the prime button down. You just say, we don't have to dump foam from the top end.

Did you just, you don't have to. You might end up doing it, but you don't have to. Dude, we're uptown now. It's more of this redneck stuff. Yeah. So with the battery in ignition on, even before the foam system's turned on, that 0.5 will be lit up, right? That don't mean the system's on. The only way we know the system's on is when the green status light is on.

When the green light's on, we know the foam foam system's on the phone. Farm systems all. It always defaults back to a half percent. I don't care what you end with it. Once you kill battery and ignition on restart, you'll always go back to a half percent default, back to a half percent no matter what. You had it end before.

All right, Phil, if I want to put it in field mode with the system off with no green light, if I start hitting that decrease button, it's gonna go from 0.5, 4, 3, 2, 1 field. Stop. When it says fill, I'll have a solid red ladder cause the valves are in the wrong position to field, right? If I turn the system on and I start hitting that decrease, you'll never see the fill mode cuz the last thing we do is turn the phone pump on the field.

So if you start with the phone pump on and you go look for a fill, you'll never find it. It has to be off to find a field load. The. Bitch flashing. I is running at full capacity. You've met, it is pumping three gallon per minute. It can't pump no more. It's just, I means it's flowing as much as it can. I, how big we think You say you got 20 gallon tape on your initial fill up.

It's usually about 25 you, cause you have to fill some other thing. All right, so the use the system is start flowing water. Once you've got water flowing open a discharge, that's foam cap. We'll turn it on. That's all you gotta do. All right, you got it. This is a picture of yours. Call it the foam control valve, you'll call it.

You'll see it called foam injection valve. That's nothing more than a diverter valve. Your valve pumps foam to two places You pump foam to your discharge. The fight fire, or you pump foam to your tank. Fill it up. That valve right there, or actually this one, this size, what? What direction that phone goes.

That right. You see in your picture there, it's halfway open. You're never gonna have it in that position. It's always gonna be down or up, right? Only time you turn it up is to fill the tank and that's it. So we'll come back to this valve when you move it, but that's your feel out drove valve, whatever you want to call it.

Alright? You have a, each one of these trucks has a foam tank drain. On the right hand side of the pump counter, you open that door, you see the, that's a quarter temp, quarter turn valve to open and close the drain on the tank. Obviously that's in the open position. Before you put any foam in 'em, you wanna make sure they're closed.

I've done it and every one of 'em come from the factory open cause they drain everything and we start dumping foam in there and we forgot to, you know, this is going straight to the ground. That's a lot of money. Makes a lot of foam. Alright, so about that. Here's another foam valve, right? Every fire starts on tank water and builds from there every one of your foam operations going start with tank foam and go from there.

So we're always gonna have, that's halfway open. Once again, it's gonna all the way be down in tank, right? That's, that will get you your phone from your tank. This time we're running low on the phone and they want to keep putting foam on it, and I got buckets of my primary agent, the same thing. I hook up the pickup tube right there, put it in a bucket of foam.

Alls I gotta do to draft foam is move that up to draft and then it's gonna start sucking the phone. All the buckets. Is that an induction system? Induction system from the, actually today we're on draft foam. We're not gonna put any foam on your tank today cause they're not sure what phone you're gonna end.

We're just using something that was already here. So basically the day when we go out there to demonstrate the fill mode, we're gonna get that mop bucket full of water and put it in the tank like we're filling it with foam, right? Then we're gonna draft the foam that we have to, and then once we're done, I'm gonna move it back to tank and use that water in, put in the tank to flush the foam pump out.

And then whenever y'all put whatever foam y'all buy to put in there, then you'll be ready to. So that right there decides whether you get your foam from buckets or from the tank, right? See how it's halfway open right there? If I take that cap off, it will drain your whole tank of foam. With that halfway open, even though you have a tank drained, it will drain backwards through that.

So that should always be carried in the tank position. All right, so I said earlier if the red light comes on, solid red got a valve in the wrong position. If I filled the tank when I got back to the station and I left this up and I killed battery remission and it defaults back to a half percent, I'm gonna have a solid red light because, In order to put phones to the discharge of the half percent, that's gotta be down, right?

And your tank selector valve should be in the tank position because that's where your first phone's going to come from. But if I put it in fill mode, I'm gonna get the same red lamp, right? So I gotta move the yellow handle up and I need to move this up to draft. Cause we got draft foam in order for it to fill, we're gonna draft it up and put it in the.

So once you move that to draft and that one up, when this infill mode, your red light goes away, you turn it on, it's gonna start picking up the foam, outta the bucket and up to the tank. Like I set, once the tank is full, it'll shut it off. If I have this down and this in in draft, but I have it hooked up, I just have the cap on it.

I'm not going to get the red lap telling me that the valve's in the wrong position. So I'll pull up to the fire, and if it's in draft, I won't have a red lamp, but I still, I'm not gonna get any phone. Pump because that's in draft instead of the tank. So once you're finish filling it up, try to always remember move that the tank and that back now so it is ready to go.

So in in draft mode it does actually take it right to the tank though. No, take it. If that valve is down, it takes it right to the pump. Just so the discharges. So if you were gonna do, if, if your primary agent's class A. We were gonna use class B phone. You would, that's how you would do that. So it doesn't necessarily the, so if I was one to flow B foam through it, I hook up the pickup too.

Put it in a bucket of B, move it to draft and start getting B3 pump. Yeah. And, and that interaction with the phone that's already in the line, this document? Yeah. I'm gonna tell you about all that. Okay.

So like with the Husky 12, just for example, the Husky 12 is next to size pump up, right? It's tied in with the water system. And so if I go from a foam to B foam with the Husky 12, it knows to flush one out before unless the other one in. There's no way to do that with this cuz it's independent of the water system.

So actually, if I wanted to draft B, I have to mix A and B home. I'm fixing until you never mix a and. But I would have to, a, would come out. Then here comes the B. But once I'm done with my incident, I need to flush this out. You can't allowed to sit there. If you're allowed to sit there, then that's when your problem starts.

But uh, I'm gonna get into there. So the fill tank, we've already talked about that I'm gonna show you. Go outside. Uh, alright. Up on top. If I want to fill manually the one that says, Hey on there, that's your phone tank, has got a vent on top. That vent. Allows air to come in so the foam will drop down to the pump.

Right? I've seen those vents get clogged up at foam. Splash it. Clog up the vent. Couldn't get no phone out. The phone pump. Couldn't figure out why. It's cause the vent was clogged up and wasn't allowed the phone it. So if you run into that, one of the troubleshooting deals is just to open the lid on that.

If you start getting phone, Then you know your vents falled up, so that's one thing. You can check paper. Mm-hmm. Up on top if you want to pour it in, open the top, pour it in the circle that sends it down that tube right there to the bottom of the tank and levels until the level comes up above that square screen in your floor.

All right. Like I said, it'll draft A or B, but the phone pump is not really big enough for. The most B foam you could pump with a three gallon per minute po foam pump is a hundred gallon a minute of water at 3%. Anything more than that, you met the full capacity of the foam pump, right? If it was me, I would never put B through there.

Y'all have inline inducers? Mm-hmm. They'll blow all the be you need to and you'll never put those together That. That because this is not going, B incidents require normally require a lot of B foam and, uh, hun a lot of water. And you, most you gonna give is a hundred gallons a minute. So if you ever mix to do, just say I did B, then I'm gonna have to do a flush once I'm done cause A and b phone.

The manual flushes nothing more. I'm going to get a trashcan full of water. Put that pickup tube in there and keep on flowing until you have tear water coming out of everything, you're just sucking water through the system till you flush it out. And I'd open the drains and everything and flush down backwards.

But the manual flushes nothing more than drafting water through the system. All right, to prime it. If I hook up my pickup tube, put it in draft, put it in a bucket of foam, open my discharge drain. Right. That's the opening on the discharge side of the pump. I turn it on and hold the prime button down. It's gonna suck the foam up from the bucket through the pumping out the drain.

When you have solid foam coming outta the drain, your pump is primed, you're ready to go. If I run it completely dry on a fire, You turned it off it. It is gotta be reprinted if I just hook it up and put it in, fill mode and refill the tank. That's a self prominent event because you have the vent at the lid.

The air will go out the top of the tank while the liquid comes in and that will reprime your pump just by putting in fill mode and refilling the tank time. All right. Discharge rang while we're here. I just told you you used the prime to pump, but also. Every once in a while. You're going is you're just not getting the phone you used to seeing.

Right? Every once in a while you get some air trapped in the phone pod, even though some phone's getting by. It's like an airlock that's not letting the full flow through there and the way you get rid of air. While that phone pump is running, if I open the discharge drain, if there's any air, you'll see spurts of air coming out the drain too.

Then solid foam, close it right back and you got rid of all the air that was in that phone pump. So you gotta, you can even call that an air bleeder. You'll do the same thing. You'll get rid of the air in the phone on your intake drain. The drains, the intake side of the pump, right where I said, see that foam strainer, I got pointed in a minute.

You're gonna see a picture of your foam strainer. All the foam that goes through the foam pump has to go through that strainer first. When we talk about mixing a and B foam. If that strainer gets clogged, you're not gonna get any phone to your phone. Phone, right? Mm-hmm. So when we raise the cab, there's easy access to the check that strainer just by I lose taking that nut off and pulling the strainer out.

You see that had water spots. Those handles. What's that? I didn't see that. Water spots on those, on those valves. On the chrome? Yeah. In trouble. The good thing is that's not your fire truck. You're looking Oh. Yours is

that picture's actually off another one, but yours is just like it, so there was no reason to change that. All right. We've already mentioned you cannot mix different brands, types of classes. In the fall, different brands and classes of foam wouldn't mix. Performing jelly lock substance, which will plug the foam injection pump cost repair a few years ago.

They tell me a lot more now. Do not mix different types of or manufactured brands of foam concentrate. The cellar pipe glass, a foam is thin, like dishwashing liver. Class B foam is thin like syrup to make sure you're putting the right foam in your tank. Every fire station I ever worked in that had an A and b uh, foam in the same fire station that got me.

Cause guys think foam is foam and it's not. A and B foam are two different things. Here's a look at Husky three strainer that had A and B mixed. If you pull that strainer out and it looks like that

when we did the phone trailer, it was wrestling. Yes. It just. So that's not what it's supposed to. It's not what it's supposed to look like. Here's a Husky, twelves trainer, same thing, just to show you what. You're not gonna get any foam anymore after, after that. So, alright, you got a 20 gallon tank, right?

You default to a hundred percent. If you don't change anything at all, you'll go through your 20 gallons of foam for every 4,000 gallons of water. If you're getting the benefit of 0.3, as you are at a half percent, alls you're looking to do is change the surface tension in the water, right. So if I go down to 0.3, then my tank last a lot longer, especially on larger fires.

That gonna go a little longer today when we'll go out there. Yesterday I said it at 0.2, just not to waste a bunch of foam for training and have pretty fun coming out of that. Point two, here's the limitations of a three gun per minute pump at a half percent, where you default to once you start flowing 600 gallon a minute in a water and.

What's they gonna say in that window? Hi. Hi. Because you met the full capacity of the pump, right? If I drop it down to 0.3, then I can flow more water before I meet the full capacity of the pump. Going back to your B foam at 3%, a hundred gallons a minute, you met the full capacity of a three gallon per minute foam pump hundred.

Will the pump allow you to actually pump more water than. No, that's just you. You gonna pump all you want. If it's flashing out, that means in there, that's as, as much as I can keep up with one. You're not Once you out, once you start pumping more, then the foam pump can keep up with you're just percentage.

Your percentages. Yeah. You're not making your percentage anymore. Alright. If I put foam in order as a foam solution, if I wanted to finish foam, I had to. These type of nozzles add to air to aate fall. All right, let's sit it on the phone suit cab lift. Make sure the foam bumpers clear before the cab. Make sure all items

I ever busted a windshield when he makes the cab. Something hitting the wind. Yeah, we were worn away. They're getting better. That busted windshield, that right there, there's a picture. That's a picture of your break right there. Same height as the top of the engine counter. Anything to slide down that engine, counter hit that brake while you're coming up with the cab.

If you don't have wh chalks out, that's the end result. Dude, that's, that was a, that was a Smithfield See in your 40. What's that? I was Allen in Smithfield Engine 40. Oh, y'all got investigate? No, actually that's in my district. I took those pictures. I had to investigate this accident. It was a, that's a bad apartment book binder that slid down and hit the brake with Memorial was coming up with the cab.

No kidding. Yeah. And, uh, when it hit the, it, you see the station in the background. Mm-hmm. It rolled across the street, hit that pole. If it had kept going, doesn't bother you in the front, across the next street, it would've went down in the body. So it actually happened at station 10. Also, a portable radio slid down and hit the brake and it just rolled down the street and stopped.

We now have you bolts over all our brakes. Should try to stop that from happening.

In order to raise the cab, battery and ignition have to be on. It could be running, but battery ignition. If I lift that red cover, move the toggle switch to raise, hope to activate switch the whole time the cab's coming up. Once the cab's all the way up, your safety arm is on the driver's side frame rail.

We pick it up and put it into. They used to teach us to lower the cab back onto the safety arm. But what happens when you do that? The wave. The cab's always being scored by on one side, and then it's twisting like that, and it could break some welds underneath. The only reason we're putting that safety arm up is if it loses hydraulic pressure, it won't come down on top of.

So why don't they put that on the same side as the. Make your fan ass walk behind.

Next question,

fire. The last question I

to edit that one. Yeah, that good. Uh, you know, some have some cap styles. They are on that side, but on these enforce, so I, once you're done and I'll show you out there. And the bad thing. So when I. Arm up, there's a catch for that arm. A lot of 'em have enough play that they can get outside of that catch, and we miss it.

And what's happened a couple times already is ones that have play, they, it didn't get into the where it's supposed to be. They brought the cab down. Well, the arm, they shoved that arm right up through the engine calendar because, oh geez, they, they missed the, I fire that engineer, built that on the wrong side.

So I think I rose. Once you're done, put the safety arm down. Put that in the, the, uh, switch and lower position hold. The activate switch the whole time the cabs come down. I don't know if you can see it, but once it's all the way down, it says I continue to hold it for five seconds. Once the cab comes to rest, then releases all the pressure off the hydraulic system and allows the cab locks to lock.

These slides, we've already covered all this stuff right here.

We've already talked about the engine cooler right here says all engine manufacturers warrant against excessive engine. Operate time at low isle during cold weather. That's at all times. If your engine is running, if you're not driving or pumping it, you probably should be in high grocery store, high bms.

Run high, checking your equipment in the morning. High, high, long periods of low aisle. We'll call field dilution lubricating oil, unburned field P into the exhaust system, carbon buildup in the cylinders, smoking and reduced performance, which to me, all this leads that DPF filter filling up more often.

It's gonna have to reach you in more often, and it simply is just not good for you to idle for long periods of time. There's a torsional vibration and low isle. You could hear the whole fire truck shaking, rattling, and shaking. You hit the high aisle switch and it all smooths out. It's another reason to be high.

Necessary to add for more than about five minutes. Hit the high I switch.

Here's a look at a turbo. The turbo takes hot air into that big silver tube into the turbo propeller, which reintroduces the hot air into the engine to give the engine horsepower. The turbo turns or propeller turns on. Turns on a. So every time you make a run, everything spins at multiple RPMs, but every time you come to a stop, it continues to spin until it quits.

They call that the cool down tower, but as long as the engine is running, the bearing is being oiled or cooled by the engine. So you go make a run, you get back to the station and you pull in or back in, whichever you do. They're turbo spinning, cooling down. If you shut your engine off right away, what you've done is you take, you have taken the oil away from that.

And they can now overheat and seize up. So when you've heard of somebody turn, uh, burning up a turbo, that's a lot of times that's the reason why. And so for that reason, you should let an ILE for a couple minutes. When you return from a run, allow your turbo to cool down before you shut off your engine.

All right. These next few slides say you need to have a maintenance program. You need to follows manufacturer's recommendation for maintenance, an operator's manage recommendation for maintenance, you need to have a checklist showing you check a fluid every once in a while. That's what all this says right here.

You're not gonna be pumping any salt water on guess. Probably not. All right. Up on top, that's your Husky three right here. That whole deal, that's the cooling system. There's a fan, and on the bottom is the IT sit on that tank right there. That's the hydraulic ball for the Husky three, that the cap is the dipstick to check the flood for the hydraulic fluid for the Husky theory.

Once again, it's gonna be up on top right there. Alright. The filter. You don't have to change for 500 hours or five years. The hydraulic filter for the Husky three. All right. We've already talked about your strainer. It's right behind an intake drain. We'll look at it and we'll go out there. Alright.

Washington can be done anytime after delivery. If you wax 'em on, they say, WA wait 90 days and wax paint only. If it's not paint, it's a graphic, whether it's the strip, the patches, or even the graphics cheap. Put on yesterday, they say they're porous. If you wax over 'em, they wipe 'em off and wax stays in the pores, actually makes 'em look.

So I don't know about your graphics, but that's what they say. They're not very good graphics. Yeah. They say with the laminates that we use, they actually say some of the ceramics actually. Proved that you do really well with them, but I would agree. I think wax is wax around. Yeah, we're headed that way with ceramics.

But yeah, I went out to Millers to talk with Jeff Miller about that home's Miller Auto Body, and he's like, we don't, we don't touch any of that stuff. Well, cause you figure it's a laminate, right? It's a gloss like vinyl lam. So it's not only is it porous, it's also susceptible to, I mean, I know it'll look nice for a couple years, but it'll, Corpus Christi, they run all their graphics by waxing them.

They run 'em all every, huh, alright to, there's tone instructions in the manual. They recommend laminate a copy, put it in the glove box in case somebody tows this firer. They don't know how they do it in the right way. And that's it.

So a.
