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, shutdown engine and check suction line for leaks,
then repeat steps (a) through (o).
p.
Adjust pump speed to meet mission requirements. Refer to Figure 2-6.
q.
Check all control panel gauges for indications of malfunctions. If a malfunction is indicated, shut down pump
immediately and refer to operator troubleshooting. Perform "during" operation PMCS (Table 2-2).
r.
Perform "during" operating PMCS (Table 2-2).
2.5.1.2 Shutdown for Non-Regulated Models. Perform the following procedures to shut down the equipment:
WARNING
To prevent rolling or sliding, do not work on equipment that is not securely
stabilized. Ensure both wheels of the equipment are secure.
Do not stand within 50 feet of operating equipment without ear protection. Failure
to obey these warnings may result in hearing loss.
CAUTION
Do not shut engine down suddenly from full speed unless an emergency exists.
Allow engine to stabilize at idle speed before shutdown.
a.
Decrease idle speed to 800 RPM then push and raise throttle control (figure 2-5, 5) from detent to idle speed for
two minutes.
b.
Close discharge valves (3) and suction valve (2).
c.
Push in EMERGENCY STOP switch (6).
d.
Perform "after" operation PMCS (table 2-2).
e.
