B. Operating Procedures
THE PROCEDURES IN THIS SECTION ARE
GENERAL OPERATING PROCEDURES. THEY
DO NOT REPLACE THE PROCEDURES AND
POLICIES ESTABLISHED BY YOUR FIRE
DEPARTMENT, NOR DO THEY REPLACE
THE RECOMMENDATIONS AND PROCEDURES
PROVIDED BY THE FIRE TRUCK MANUAL.
Pumping From a Hydrant, General
Operation
1. Position the truck for the best hydrant hookup
and discharge hose layout.
REFER TO THE FIRE DEPARTMENT
PROCEDURES ON SETTING WHEEL CHOCKS
AS WELL AS LAY OUT AND CONNECTION
OF SUCTION AND DISCHARGE HOSES.
ALL VALVES, DRAIN COCKS, AND CAPS
SHOULD BE CLOSED.
NEVER ATTEMPT TO SHIFT THE PUMP
TRANSMISSION WHILE THE TRUCK
TRANSMISSION IS IN GEAR. ALWAYS
SWITCH THE TRANSMISSION TO “N” AND
VERIFY THE SPEEDOMETER IS “0” BEFORE
MAKING PUMP TRANSMISSION SHIFT.
2. Bring the truck to a complete stop before you
attempt to shift from road to pump.
3. Apply the truck parking brake.
4. Shift the truck transmission to the NEUTRAL
position.
5. Move the in-cab pump shift control valve from
the ROAD position to the PUMP position. The
shift warning lights should come on in a
second or two, indicating a complete shift.
If the truck manufacturer has used another in-
cab valve to achieve pump shift or has an
electric switch, follow the instructions supplied
with that valve.
6. After pump shift is completed, put the truck
transmission in the proper pump operating
range or gear. For most pumpers this will be
direct drive (1:1) ratio. In addition, the
speedometer should read 5 to 15 MPH after the
shift has been completed. If the shift does not
seem to be completed, shift truck transmission
to “N” and repeat the entire procedure. Note
that some vehicles drive the speedometer
from the front wheel of the chassis. In this
case, the speedometer will not read 5 to 15
MPH after shifting to the pump position. See
the chassis manual for details.
DO NOT LEAVE THE CAB OR ATTEMPT TO
PUMP UNTIL ALL THE GREEN PUMP
LIGHTS IN THE CAB AND PANEL ARE ON.
7. Exit the driving compartment only after all the
above steps are completed and you are sure
that the shift completed lights in the cab and
panel are on.
DO NOT OPEN THROTTLE UNLESS ALL
GREEN PUMP INDICATOR LIGHTS ARE ON.
