TRUCK START-UP AND SHUT-DOWN PROCEDURES

To ensure that your fire truck is ready for service, make the following daily inspections:

DAILY CHECKS

  1. Make visual inspection of entire apparatus.
  2. Check tires for proper inflation.
  3. Check all air reservoir drains and close any that may be open.
  4. Check the area underneath the truck for signs of leaks. If noted, check hoses and lines for leaks. Correct the condition causing the leak.
  5. Check the windshield washer fluid level and refill if needed.
  6. Check all oil and coolant levels, including engine, pump, and axles.

SAFETY CHECKS

Equally important as the pre-starting checks is a complete safety check of your vehicle.

  1. Make a check of all lighting including high and low beams, Burn signals, hazard flashers, brake, tail and backup lights and warning lights. Repair any defective lights.
  2. Check the windshield washers and wipers.
  3. Check the operation of all instruments, gauges, and controls.

After performing the pre-starting checks and safety checks, you are ready to operate the vehicle. Start engine and make sure all systems are functioning.

STARTING THE ENGINE

WARNING: All internal combustion engines give off hazardous fumes and gases while running. DO NOT start or run the engine in a closed or poorly ventilated building where the exhaust gases can accumulate.

CAUTION: Before operating the truck, the driver should be familiar with the Operator's Manual furnished by the engine manufacturer for procedures and recommendations on engine starting and use.

  1. Before starting engine, turn battery switch to the ON position (Battery switch is located below and left of driver's seat next to door.) (Figure 6.1)
  2. Turn Ignition Switch to ON position. (Figure 7.1)
  3. Push the Starter Button until the engine starts.
  4. After the engine starts, if necessary run the engine at a slightly higher RPM to build up air pressure to release the parking brake.
/
Figure 6.1 & 9.1
  1. Push the Parking Brake Control Button IN to release the spring brakes (yellow button) (figure 8.1). Wait until the red parking brake light goes off before attempting to move the vehicle.
  2. The Low-Air Pressure Warning Light and Buzzer will be on until both the front and rear systems have approximately 60 PSI pressure
CAUTION:If the engine does not start within 15 seconds,release the starter buttons and allow the starter motor tocool for 60 seconds. Then step 3. /
Figure 7.1

Figure 8.1
STOPPING THE ENGINE
Read the Engine Operating Manual furnished by the engine manufacturer for recommended procedures.
  1. Bring the truck to a complete stop using the service brakes.
  2. Shift the transmission into NEUTRAL.
  3. Set parking brakes by pulling the Parking Brake Control (yellow button). (Figure 8.1)
  4. Turn off all DOT and Warning lights.
  5. Turn Ignition Switch to OFF position.
  6. While departing the vehicle open the door and turn the Battery Selector Switch to the OFF' position. (Figure 9.1)
  7. Battery Selector to OFF.
/ Figure 9.1
(See Figure 6.1)
CAUTION:Do not turn battery selector switch to OFF position until the engine has completely stopped. Switching to OFF before the engine has stopped will damage the electrical system.

ALLISON WORLD AUTOMATIC TRANSMISSION

CAUTION: Refer to TRANSMISSION MANUFACTURER'S MANUAL for complete operating and services information.

  • This transmission has five forward speeds and one reverse. Shifting within any of the forward drive ranges selected is fully automatic, except for fifth gear. To obtain fifth gear, which is overdrive, the MODE button on the shift pad must be engaged. A red LED will appear next to the MODE button when fifth gear is enabled. Fifth gear should only be used on highways and should not be used for in town driving. (Figure 10.1)
WARNING:If at any time the engine will be left running while the operator is not at the controls, THE OPERATORMUST SHIFT THE TRANSMISSION TO NEUTRAL, SET THEPARKING BRAKE, AND CHOCK THE WHEELS.
NOTE: The Transmission Shift Pad Monitor displays the current gear selection. /
Figure 10.1
R / Use this for backing the vehicle. The vehicle should be completely stopped before shifting from a forward gear to reverse or from reverse to forward. Reverse has only one gear.
N / Use the neutral position when you start the engine. If the engine starts in any other position, the Neutral Start Switch is malfunctioning. (Notify the Maintenance Shop when this occurs.)
D / Use this gear for all normal-driving conditions. The vehicle will start in first gear, and as you depress the accelerator, the transmission will up Shift to second gear, third gear and fourth gear, automatically. As the vehicle slows down, the transmission will downshift to the correct gear, automatically.
3/2 / Occasionally, the road, load, or traffic conditions will make it desirable to restrict the automatic shifting to a lower range. When the conditions improve, return the range selector to the normal position. These positions also provide progressively greater engine braking power (the lower the gear ranges the greater the braking effect).
1 / This is low gear for use when pulling through mud and snow or driving up or down steep grades. This position provides maximum engine driving or braking power. In the lower ranges (1, 2, and 3), the transmission will not up shift above the highest gear selected unless the recommended engine governed speed for the gear is exceeded.

EMERGENCYLIGHTING

The overhead Switch Panel and the Class One Load Manager control all the Emergency Lighting. Each switch in the overhead Switch Panel actuates different lights, Beacon, Strobes, Head Light Flasher, Front warning, Rear Warnings and Opticom Light. These Warning Lights can be actuated individually or in a group.

To turn on each type of warning light independently, first turn on the Warning Master Switch then switch warning lights on independently as desired. (Figure 12.1) To turn on a particular selection of warning lights all at the same time, select the desired warning lights and toggle those switches to the ON position. Then toggle the Warning Master Switch to the ON position. To turn off those lights, toggle the Warning Master Switch to the OFF position. The Load Manager also controls all warning lights. This means the Load Manager sequences the lights on, when the Warning Master Switch is toggled ON. It also sequences them off when the Warning Master Switch is turned off. The Load Manager may also turn off selected lights in the event of low voltage. The Load Manager will not turn off the beacons in the light-bar or the rear rotators. The Load Manager also controls the white flashing lights at the front of the truck. When the truck is parked the white flashing lights will be turned off. This is required by NFPA.

CLASS ONE LOAD MANAGER

The Load Manager controls almost all lighting on the truck, except for D.O.T. lighting. The Load Manager has no effect on truck or pumping operations.

SEQUENCING

The Load Manager sequences in priority order from 1 to 8 when the respective switch is activated (either ignition or Warning Master Switch) and the vehicle is operated in the mode selected for that output (response and/or scene.) Loads will sequence off in reverse order. Priority zero loads will be sequenced on and off but will not shed.

SHEDDING

Electrical loads will be turned off (shed) when the system voltage drops to the shed point for a minimum of 1 minute (this prevents load shedding due to momentary system power loading such as high current start-up devices.) Once shed, loads will remain off for a minimum of 5 minutes and until the un-shed voltage is achieved for a minimum of 1 minute. Loads will only shed if the Parking Brake is set.

FAST IDLE

A fast idle output is activated whenever the system voltage is reduced to 12.8 VDC for at least one minute. The fast idle output will remain ON for a minimum of 10 minutes and until 13.0 VDC is achieved. The fast idle output is dependent on the Parking Brake.

SWITCH SOURCES

Ignition

  • Loads will sequence on when the vehicle ignition switch is turned ON.

Warning Master Switch

  • Loads will sequence on when the master warning switch is turned ON.

PUMP OPERATION

To start the set up for pump operation, always set the parking brake and chock the wheels.

Remember, Safety First.

PUMPSHIFT ENGAGEMENT & DISENGAGEMENT
ENGAGEMENT
Make sure the vehicle transmission is in Neutral. Once the transmission is confirmed to be in Neutral. Then shift the pump air shifter from ROAD to PUMP. (Figure 15.1)At this time the PUMP ENGAGED LIGHT should come on, if the PUMP ENGAGED LIGHT fails to come on, shift vehicle transmission using the selector pad from Neutral to Drive and back to Neutral. This gives the driveline a chance to spin to align the gears in the pump transmission. Then place the vehicle transmission into Drive. At this time you will get a Pump Engage light and an Ok to Pump light. You now can move back to the pump panel. At the pump panel the MasterDischarge gauge should be showing a positive pressure, if not open the "Tank to Pump" valve. If a positive pressure is still absent, pull the primer handle until it does. /
Figure 15.1

PRIMING THE PUMP

To begin pumping operations the pump must first be primed. To prime the pump, close all discharge valves, drains, Pump Cooler, and all intakes. Then open the hydrant or Tank to Pump valve, depending on the water source. Pull on the Primer Handle, you should hear the primer motor start running, continue to run the primer until you hear water hitting the ground.

CAUTION:Do not run the Primer Motor for more than sixty seconds. Running the Primer Motor for more than sixty seconds may cause damage/ failure to the Primer Motor.

If the pump does not prime in the appropriate amount of time, (15 to 45 seconds) check the water source and check for possible air leaks. Try to prime the pump again.

PRIMING THE PUMP- continued

PRIMER PUMP OIL SITE GLASS

The oil level for the primer pump can be viewed on the passenger side of the apparatus, located on the pump discharge panel.

Once the Master Discharge gauge is showing a positive reading, then increase the throttle as per the FIRE COMMANDER portion of this manual. (In RPM Mode)

DISENGAGEMENT
  • To remove from pump gear, after pumping operations are completed, push the idle button on the FIRE COMMADER. Then go to the cab and place the vehicle transmission into Neutral.
CAUTION:FAILURE TO PLACE VEHICLE TRANSMISSION IN NEUTRAL BEFORE SHIFTING PUMP TRANSMISSION WILL RESULT IN PUMP TRANSMISSION FAILURE!
  • After assuring that the vehicle transmission is in Neutral, shift the PUMP SHIFT to Neutral and wait for the truck speedometer to read zero, then finish shifting the PUMP SHIFT to ROAD.

PRESSURE GOVERNOR
Operating the Detroit Diesel Electronic Fire Commander (DDEFC):
MODES:
There are two modes of operation for the Electronic Fire Commander, the RPM MODE and the Pressure MODE. The RPM MODE maintains the engine speed at a set RPM. The PRESSURE MODE controls the engine speed to maintain a set pump discharge pressure. The operating mode of the FIRE COMMANDER can be changed from RPM MODE to PRESSURE MODE and back without the need to return to idle. When the MODE switch is pressed, the FIRE COMMANDER will change from one mode to the other and utilize the RPM or pump pressure that is current at the time the change is made for engine control. /
