Question 15

Emergency Air Brake

Answer 15

Depressing green emergency button will temporarily release the brakes so apparatus can be moved off the roadway.
Max speed 2 mph.

Question 16

Engine series

Answer 16

Series 60
Inline 6 cylinder
4 stroke
470 and 515 hp

Question 17

Possible check engine light reasons

Answer 17

Low coolant, high oil temp, high coolant temp, low oil pressure, sensor malfunction, or apparatus not plugged into shoreline for extended periods of time.
-If light activated call Fire Maintenance

Question 18

Fuel tank capacity

Answer 18

65 gallons

Recommend filling fuel tank every day to reduce fuel condensation and to avoid running out of fuel at a fire scene.

Question 19

Coolant gauge normal temp

Answer 19

180-220 degrees Fahrenheit

High temp possible causes are low coolant, overuse of retarder, belt shaft not driving fan properly, radiator plugged with dirt and debris

Question 20

Engine oil PSI

Answer 20

Normal 15-80 PSI cold or high idle, 5-60 hot at idle

Question 21

Volt gauge

Answer 21

Indicates battery condition and voltage output

Normal reading 13.5-14.8

Low reading possible causes
Loose or missing bolts, low state of battery charge, current load on system greater than alternator can produce, or defective alternator.
Call fire maintenance if alternator is not charging

Question 22

Front air gauge

Answer 22

Normal 90-130 PSI

Question 23

Rear air gauge

Answer 23

Normal air pressure is 90-130 PSI

Question 24

Fuel pressure norms

Answer 24

5-90 PSI

Question 25

Transmission oil temp

Answer 25

Normal 160-220. Maximum temp 330 intermittently Possible high temp causes: low transmission fluid, overuse of retarder, low coolant

Question 26

4 things to check for when looking at hoses

Answer 26

Cracking Leaking Mushy hoses Loose clamps

Question 27

What does the load manager do?

Answer 27

Sequentially energizes and de-energizes relays at half-second intervals in order to reduce spikes in a vehicle's electrical system. Also detects when the vehicle's load is greater than the output of the alternator. When this occurs, loads are sequentially de- energized until the alternator output is equal to the load. KEEP ON AT ALL TIMES

Question 28

Airline filter on some ladder trucks

Answer 28

Some ladder trucks are equipped with an airline filter assembly next to the large breathing air storage tanks. This filter is equipped for 125 psi max. Ideally, pressure should be set at under 125 psi. All the air needed at the bucket is 100 psi

Question 29

Pressure Governor-throttle mode

Answer 29

When the parking brake is set and the transmission is in neutral position, it is possible to increase the RPMs of the engine. Each movement will increase the RPMs by increments of 25

Question 30

Pressure Governor-Pressure mode

Answer 30

When in pressure mode, each movement of the switch will increase the PDP by 4 PSI

Question 31

Pressure Governor-Pump

Answer 31

The system shutdown button must be pushed for 1-2 seconds prior to switching transmission out of pump gear

Question 32

Pressure Governor-system shutdown

Answer 32

Push button down to shut down governor to idle. When operating in high water flow operations, the pressure should be gradually reduced prior to shutting down the system, when possible.

Question 33

Raising cab

Answer 33

Always use stay arms before working on apparatus. Do not rest the entire weight of the cab on the stay arm. If possible, place control lever to raise position to hydraulically lock.

Question 34

How does the retarder slow the vehicle?

Answer 34

The retarder uses viscous property of the transmission fluid to retard the driveline. When activated, transmission fluid is introduced into the retarder housing and energy is introduced into the fluid through the opposing action of the spinning vanes. This retards the vehicle through the rear wheels and adds heat to the transmission fluid. This heat is dissipated through the transmission cooler and radiator.

Question 35

How much braking does the retarder apply?

Answer 35

Quantum are configured at 33% and 67% braking. The retarder is applied to 1/3rd of it's capacity when the throttle pedal is released. It is then applied to it's full capacity when the brake pedal is depressed.

Question 36

When should the retarder be turned off?

Answer 36

Wet weather

Question 37

PSI required to activate steps?

Answer 37

85 PSI. The steps operate with air from the wet tank of the air brake system.

Question 38

Transmission Info

Answer 38

``` Allison automatic Dexron ATF or TransSynd cold check 60-120 degrees F hot check 160-200 degrees F (should always be checked in hot mode) ```

Question 39

Transmission Fluid Check Procedure

Answer 39

- Park on level surface - shift to neutral and apply parking brake - shift to drive, then to reverse. shift back to neutral and let engine idle for 2 minutes - wipe dipstick clean and then check. If fluid is too high, the fluid can aerate. This will cause the transmission to shift erratically or overheat.
