PUMPING FROM DRAFT
1. Position chassis as close to the water source as possible 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. The pump will exceed the rated capacity on a ten
foot vertical lift, however, as the lift increases, performance and capacity will
decrease.
2. Attach hard suction hose to the suction nipple on pump and attach the hose strainer to the
other end. Be sure suction hose gasket and inlet strainer are in place, and all drain valves
are closed.
3. For best results, submerge suction strainer two feet or more in the water and avoid
pumping large volumes from shallow water.
4. Maintain engine idle speed and engage power take-off device. Pull out primer handle.
CAUTION: Care must be exercised not to operate pump without water as this can
seriously damage pump.
5. 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.- Set
relief valve operating pressure per the specific instructions supplied elsewhere in this
manual.
