When do you add fluid to your engine?

When the fluid level is below the "add" mark

1

What's the max time allowed for air pressure to build after starting?

60 seconds

2

At idle the pump discharge should be approx?

50 psi

3

How much does stopping distance increase on slippery roads?

3-15 times

4

What do you do if vehicle starts to skid?

Ease off the gas, steer slightly into the skid, look where you want the vehicle to go.

5

Does the jake break affect ABS system?

No. The abs system will turn the jake break off whenever traction is lost and will reactivate it when abs system is turned off.

6

Jake break procedure in slippery conditions

Start with it off, use normal engine breaking, if no loss of traction turn jake break on to the low setting, if slippage occurs turn it off immediately

7

Can you use jake break in medium or high during slippery conditions?

Yes on medium but not recommended on high

8

When do you use a transmission retarder when slippery?

Never

9

On type 3 engines, less than ______mph is required to engage front axle.

10

10

Two things are required to shift the transfer case on type 3

Transmission in neutral, and parking break set

11

How is percent of slope measured?

Rise divided by run

12

How is degree of slope measured?

It is roughly half of the percent of slope

13

What is the max slope percentage you can drive up or down?

35-40%. Angle greater than 40% raises the front end and compresses the back end

14

To maintain rolling friction, how long do you break firmly for?

3-5 seconds. I you have to longer your going to fast.

15

Max slope degrees drive able on a side hill?

25 degrees

16

Four concepts of getting unstuck

Lighter by dumping water. Bigger footprint by airing down. Better traction by using dun age. Digging runways

17

Before entering roadway after off road, what do you check?

Tires, undercarriage, 4 wheel drive, compartments

18

Which way do you turn wheels when parking uphill and downhill?

Headed uphill-away from the curb.
Downhill-toward the curb.
Roll slowly until the wheel touches the curb then set the brake

19

When blocking what is taken into consideration when deciding which way to block?

Type of incident and the direction you want to divert traffic

20

On a vehicle accident what is the safest way to block?

Block left to protect crews working from extrication and medical compartments.

21

On a vehicle fire what is the safest way to block?

Block right to protect the engineer at the p

22

If neither vehicle accident or vehicle fire which way do you block?

Block in the direction you want to divert traffic

23

What if it is not possible to block right or left?

Park straight and turn wheels left or right depending on traffic

24

How far should cones be spaced?

25-30 feet apart initially

25

Where should the air unit be parked on an incident?

Clean air location

26

At a medical aid who gets the best spot?

Ambulance

27

When positioning on a wildland fire consider what?

Keep road clear, windows up, back into position, protection line, position on lee side of structure if possible

28

What type of engine is in our KME

Caterpillar C13, 430 horse power, four stroke, six cylinder

29

How big is fuel tank on KME

65 gallons

30

What kind of brakes are on our KME

Front disk, rear drum, abs

31

How does a jake break work?

When activated, it opens exhaust ports in the cylinders releasing the compressed air thus slowing the engine

32

How does a transmission retarder wrk?

An external accumulator holds extra transmission fluid. When activated the air system shoots fluid into the retarder cavity. When the fluid interacts with the rotating and stationary veins it provides resistance thus slowing the output shaft

33

How much do the ladders on the ladder rack weigh?

400 lbs

34

What type of generator on our KME

Honda 1500 watt portable gasoline with electric start

35

What does the last notch on the tab indicator of the brake lining indicate

1/4 inch of pad remaining

36

What percentage of the rear springs can be cracked or broken

No more than 25 percent

37

What should the depth of tread and psi be in the front tires

4/32 of an inch of tread and 100-120 psi or manufacture recommendations

38

What is the tread depth on the rear tires

2/32 of an inch of tread

39

How far down should the mud flaps be

2/3 down from the top of the tire

40

What if the air filter restriction gauge reads in the red

Notify the mechanic

41
