P.T.O. PUMP OPERATION INSTRUCTIONS PUMPING FROM HYDRANT
1. Position chassis near hydrant and set parking brake. Place truck transmission in neutral.
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. Open hydrant valve slowly to avoid rush of water.
4. Maintain engine idle speed and engage power take-off device.
5. Open discharge valve on pump.
NOTE: It is not necessary to use primer when pumping from hydrant. Accelerate
engine and adjust discharge valves to obtain desired pressure and volume. Set relief
valve operating pressure per the specific instructions supplied elsewhere in this
manual.
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. Place truck transmission in neutral. 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. Open valve in supply line from booster tank to pump suction.
4. Maintain engine idle speed and engage power take-off device.
5. Pull out primer handle. When discharge gauge registers pressure, open discharge line, and
release primer handle.
6. Accelerate engine and adjust discharge valves to obtain desired pressure and volume.
CAUTION: Do not try to pump a large volume of water, as suction supply line from
the tank will not handle it.
