Front Mount Pump Operation Instructions
Pumping from Hydrant
1. Position chassis near hydrant and set parking brake. Shift truck transmission
to neutral position. Caution: Make sure that truck transmission shift quadrant
lock is used. Place wheel chocks in front and behind tires.
2. Attach one end of the suction hose to the hydrant and the other end to the
pump suction connection. Be sure the inlet strainer is installed and all drain
valves are closed.
3. Maintain engine idle speed, open hydrant, and slowly engage clutch in pump
transmission.
Caution: If clutch does not shift easily through its 180 degree travel,
do not force it, as this may cause serious damage to the pump
transmission. Instead, back the clutch off and re-engage it.
4. When discharge gauge registers pressure, open discharge line.
Note: It is not necessary to use primer when pumping from hydrant.
5. Accelerate engine and adjust discharge valves to obtain desired pressure and
volume.
6. When using soft suction hose between pump and hydrant, do not use
nozzles of larger capacity than the hydrant will supply.
Pumping from Booster Tank
1. Position chassis and set parking brake. Shift truck transmission to neutral
position. Caution: Make sure that truck transmission shift quadrant lock is
used. Place wheel chocks in front and behind tires.
2. Close all drain valves.
3. Maintain engine idle speed, open tank to pump supply line valve, and slowly
engage clutch in pump transmission.
