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.

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 the
pump fails to take suction, shut down the engine and check suction line for leaks, then
repeat steps (a) through (o).
a.
Adjust pump speed to meet mission requirements. Refer to Figure 2-6.
b.
Check all control panel gauges for indications of malfunctions. If a malfunction is indicated, shut down pump
immediately and refer to operator troubleshooting.
c.
Perform “during” operation PMCS (Table 2-2).
2.5.2 Shutdown.
Perform the following procedures to shut down the equipment:
To prevent rolling or sliding, do not work on equipment that is not securely stabilized.
Ensure both wheel of the equipment are chocked.
Do not stand within 50 feet of operating equipment without ear protection.
Failure to obey these warnings may result in hearing loss.
Do not shut engine down suddenly from full speed unless an emergency exists. Allow
engine to stabilize at idle speed before shut down.
Do not allow water to remain in the water pump if the 350 GPM Pump Assembly is not
going to be operated for a period of time or in inclement weather.
Failure to drain the
water from the water pump could result in equipment damage from freezing or sludging
(deposits forming).
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 2-3).
e.
Close Control Panel as follows:
(1) Press in on end of quick release pin and remove pin from brackets at top of Control Panel and Cover.
(2) Lower control panel cover.
(3) Turn the two fasteners on the control panel clockwise until the fasteners engage.
