TM 10-4320-316-14
NOTE
If engine does not start on first pull, repeat steps (5), (6), and (7).
(8)
After 1 to 3 minutes, the centrifugal pump will start pumping water.
(9)
Close access panel (2) and engage latch (1).
b. Adjusting Speed. After engine has been started, the engine speed must be adjusted to set the DED pump
assembly to pump the required rate of water. To adjust the engine speed, perform the following steps. (Refer to Figure
2-5.)
(1)
Rotate throttle control handle (5) 1/4 turn counterclockwise and either pull out the throttle control to
increase speed or push in throttle control handle to decrease speed until desired pumping rate is achieved.
(2)
Rotate throttle control handle (5) 1/4 turn clockwise to lock handle when the desired speed and
pumping rate are achieved.
c. Stopping. When the pumping operation is complete, the DED pump assembly must be shutdown by
stopping the engine. To shutdown the DED pump assembly, perform the following steps. (Refer to Figure 2-5.)
CAUTION
·
Do not stop engine suddenly since it may cause the temperature to get too
high and cause possible damage to the engine. When stopping the engine,
reduce the load slowly and allow the engine to run at idle speed for 3 minutes
before stopping engine.
Do not stop engine with the decompression lever as engine damage may
result. If the engine cannot be stopped by the throttle control, then move the
fuel cock handle to the horizontal to close the cock and cut off fuel flow to the
engine.
(1)
Rotate throttle control handle (5) 1/4 turn counterclockwise and slowly move throttle down until engine
is running at idle speed. Lock throttle control into this idle position by rotating throttle control handle 1/4 turn clockwise.
(2)
Allow engine to run at idle speed for 3 minutes.
(3)
Close any discharge water valve in the water system and then close any suction valves that are
installed in the hoses. This will retain liquid in pump unit and reduce or eliminate the need to prime the pump for the next
pumping application.
(4)
Rotate throttle control handle (5) 1/4 turn counterclockwise and push throttle control handle all the way
down to stop the engine.
