Q

HOW DO YOU ENGAGE THE PUMP?

MANUAL PG.21

A
  1. Shift Transmission Into Neutral (N)
  2. Pull Parking Brake to Apply to prevent vehicle from rolling
    *If the parking brake is OFF, safety interlocks prevent hand throttles or pressure governors from operating.
    NOTE:
    • Manual Override: The pump speed will then be controlled only by the driver’s throttle pedal. 3. Chock the Wheels
    Block both front and rear of tire using wheel chocks every time you park the vehicle.
    • If the parking brake is applied, but then released during pump operation, the hand throttle or pressure governor will be disconnected, and the engine speed will fall to IDLE. A loss of water pressure will result.
  3. Apply the Service Brake by depressing and holding the Brake Pedal.
  4. Engage the Pump Shift Control
  5. Look at Indicator Light
  6. SHIFT TRANSMISSION TO DRIVE
  7. LOOK AT SPEEDOMETER 8-12MPH
  8. LOOK AT INDICATOR LIGHT

Q

WHAT HAPPENS IF THE AIR BRAKE IS OFF AND THE PUMP IS ACTIVATED?

MAUAL PG.21

A

If the parking brake is OFF, safety interlocks prevent hand throttles or pressure governors from operating.

16
Q

WHAT SHOULD THE AIR PRESSURE GUAGE REGISTER TO ACTIVATE PUMP.

MANUAL PG.22

A

Make sure that the air pressure gauges indicate that the air pressure system is at 80 PSI or greater. The pump may not shift out of road position if the air pressure is below 80 PSI.

17
Q

HOW LONG SHOULD YOU WAIT FOR PUMP TO BE ENGAGED?

MANUAL PG.22

A

Wait up to 4 seconds for pump to engage.

18
Q

WHAT DOES THE PUMP ENGAGED INDICATOR LIGHT TELL YOU?

MANUAL PG.22

A

It confirms that air pressure has been sent to the pump shift actuator in the pump house and the actuator has moved. This means that the pump transmission has shifted.

19
Q

WHAT SHOULD YOU DO IF THE GEAR TEETH FAIL TO MESH WHEN PUTTING APPARATUS INTO PUMP.

MANUAL PG.23

A

• Shift chassis transmission into Neutral (N)
• Shift chassis transmission into Reverse (R)
• Shift chassis transmission into Neutral (N)
• Shift chassis transmission into Drive (D)
Transmission should shift into pump. Repeat steps as necessary.

20
Q

If the pump engaged light does not illuminate after the pump shift lever is moved from ROAD to PUMP, an incomplete shift has occurred. WHAT SHOULD YOU DO?

MANUAL PG.23

A

confirm:
• that the air pressure is above 80 PSI;
• the parking brake is applied;
• the wheels are chocked.

21
Q

WHAT SHOULD THE SPEEDOMETER READ WHEN PUMP IS IN GEAR?

MANUAL PG.23

A

12 to 18 MPH and the vehicle is NOT moving

22
Q

HOW DO YOU OPERATE THE MANUAL PUMP SHIFT CONTROL?

MANUAL PG.24

A
  1. Position One Person in the Driver’s Seat and One Person at the Pump Panel
  2. Shift the Transmission into Neutral (N)
  3. Pull Parking Brake to Apply
  4. Apply Service Brake by Depressing and Holding Brake Pedal.
  5. Place Pump Shift Control in NEUTRAL
    Move the Pump Shift Control located in the cab into the middle or NEUTRAL position.
  6. Engage Manual Shift Handle (Figure 3-2)
  7. Place Pump Shift Control in PUMP
    Move the Pump Shift Control back into the PUMP position.
  8. Shift the Transmission into Drive
23
Q

HOW LONG DOES IT TAKE WATER TO REACH BOILING IN THE PUMP WHEN NOT CIRCULATING?

MANUAL PG. 28

A

SECONDS

24
Q

WHAT DOES THE ENGINE COOLER DO?

MANUAL PG.29

A

IT CIRCULATES WATER TO THE ENGINE USING THE HEAT EXCHANGE TO DRAW HEAT AWAY FROM THE ENGINE.

  • INCREASES TANK WATER TEMP
  • SHOULD BE TURNED OFF TO PROVIDE MORE HEAT TO THE PASSENGER COMPARTMENT.
25
Q

WHAT DO YOU DO IF HAND THROTTLE SWITCH FAILS ON PUMP PANEL?

MANUAL PG.30

A

ASSIGN SOMEONE TO OPERATE FOOT PEDAL THROTTLE INSIDE CAB HOLDING STEADY PRESSURE.

26
Q

WHAT IS PUMP PRESSURE DETERMINED BY?

MANUAL PG.30

A

• Engine Speed
• Pump Size
• Discharge Restriction (size and length of discharge hose)
• Intake Restriction (size and length of intake hose)
• System Restriction (size and shape of valves, fittings, manifolds, etc.)

27
Q

WHAT DOES THE PRESSURE GOVERNOR DO?

MANUAL PG.30

A

regulates the engine speed automatically to maintain the desired pump pressure.

28
Q

DOES AN ENGINE AT IDLE CREATE PUMP PRESSURE?

MANUAL PG.32

A

YES

CLOSE VALVES TO DISCONTINUE PRESSURE TO HOSE LINES.

29
Q

WHAT CAN THROTTLE CONTROL MODE CAUSE?

MANUAL PG.34

A

SPIKES IN PUMP PRESSURE WHICH CAN INJURE OR KILL FIREFIGHTERS.

*ALWAYS PUMP IN PRESSURE CONTROL MODE

30
Q

WHAT IS THE THROTTLE CONTROL MODE USED FOR?

MANUAL PG.34

A
