Operation
❑
Another factor that can limit LIFT
when drafting is barometric pres-
sures below 29 in.Hg. High eleva-
tions and storm conditions can
affect maximum flow available from
any pump.
Pumping from Draft
1. Get as close to the water source as
practical. The pump can draw 100%
of its rated capacity with less than a
10 foot (3.05 meters) vertical lift and
20 feet (6 meters) of suction hose.
As the lift increases to above 10 feet (3 meters), pump capacity is reduced.
2. Bring the truck to a complete stop and apply the truck parking brake.
CAUTION !
REFER TO DEPARTMENT PROCEDURES FOR SETTING WHEEL CHOCKS
AND LAYING OUT SUCTION AND DISCHARGE HOSES. ALL VALVES, DRAIN
COCKS, AND CAPS SHOULD BE CLOSED.
3. Shift the truck transmission to NEUTRAL.
4. Make appropriate suction hose connections. Use a high flow suction hose
basket strainer and keep hose out of silt laden areas.
5. Engage the PTO (power take-off) per the PTO manufacturer’s instructions.
(Within a few seconds the shift warning indicator lights, indicating a complete
shift.)
WARNING !
DO NOT LEAVE THE CAB OR ATTEMPT TO PUMP UNTIL ALL THE GREEN
PUMP LIGHTS IN THE CAB AND PANEL ARE ON.
6. Exit the driving compartment only after all the above steps are completed and
the indicator lights in the cab and on the panel are ON.
