Driving Flashcards
What’s the max time allowed for air pressure to build after starting?
60 seconds
When do you add fluid to your engine?
When the fluid level is below the “add” mark
At idle the pump discharge should be approx?
50 psi
How much does stopping distance increase on slippery roads?
3-15 times
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.
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.
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
Can you use jake break in medium or high during slippery conditions?
Yes on medium but not recommended on high
When do you use a transmission retarder when slippery?
Never
On type 3 engines, less than ______mph is required to engage front axle.
10
Two things are required to shift the transfer case on type 3
Transmission in neutral, and parking break set
How is percent of slope measured?
Rise divided by run
How is degree of slope measured?
It is roughly half of the percent of slope
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
To maintain rolling friction, how long do you break firmly for?
3-5 seconds. I you have to longer your going to fast.
Max slope degrees drive able on a side hill?
25 degrees
Four concepts of getting unstuck
Lighter by dumping water. Bigger footprint by airing down. Better traction by using dun age. Digging runways
Before entering roadway after off road, what do you check?
Tires, undercarriage, 4 wheel drive, compartments
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
When blocking what is taken into consideration when deciding which way to block?
Type of incident and the direction you want to divert traffic
On a vehicle accident what is the safest way to block?
Block left to protect crews working from extrication and medical compartments.
On a vehicle fire what is the safest way to block?
Block right to protect the engineer at the p
If neither vehicle accident or vehicle fire which way do you block?
Block in the direction you want to divert traffic
What if it is not possible to block right or left?
Park straight and turn wheels left or right depending on traffic
How far should cones be spaced?
25-30 feet apart initially
Where should the air unit be parked on an incident?
Clean air location
At a medical aid who gets the best spot?
Ambulance
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
What type of engine is in our KME
Caterpillar C13, 430 horse power, four stroke, six cylinder
How big is fuel tank on KME
65 gallons
What kind of brakes are on our KME
Front disk, rear drum, abs
How does a jake break work?
When activated, it opens exhaust ports in the cylinders releasing the compressed air thus slowing the engine
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
How much do the ladders on the ladder rack weigh?
400 lbs
What type of generator on our KME
Honda 1500 watt portable gasoline with electric start
What does the last notch on the tab indicator of the brake lining indicate
1/4 inch of pad remaining
What percentage of the rear springs can be cracked or broken
No more than 25 percent
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
What is the tread depth on the rear tires
2/32 of an inch of tread
How far down should the mud flaps be
2/3 down from the top of the tire
What if the air filter restriction gauge reads in the red
Notify the mechanic
Normal volt meter reading
12-14 volts
Minimum fuel level
3/4 of a tank
Normal water temp
170-210 degrees
Normal oil pressure
35-75 psi
Normal trans temp

How much play should be in the steering wheel
No more than 10 degrees in a 20” wheel, this equals 2 inches
Where do you check the coolant level
At the radiator, not the overflow reservoir
What is the fuel mixture on 2 stroke engines in SBC
50:1 gas to oil
What is the pneumonic for air brakes test
Gov cut out Gove cut in S static A applied L low air P pop out A air recovery T tug
