TM 10-4320-324-14
2-7. Operating Procedures (CONT).
Table 2-2. Performance Data
CAUTION
As pump begins to pump, reduce engine speed and reduce discharge valve opening to prevent hydraulic
shock to system when line is filled too fast, causing hose rupture and fitting failure.
NOTE
When pump picks up prime, a change in engine RPM will be noted.
Depending on pumping conditions, pump may not take suction immediately; it may be necessary to fill
suction line with liquid before the pump takes suction. If after a reasonable time pump fails to take
suction, shut down engine and check suction line for leaks, then repeat steps (1) through (13).
(14)
Readjust pump speed to desired level (Table 2-2).
(15)
Check all control panel gauges for indications of malfunctions. If a malfunction is indicated, shut down pump
immediately.
