e. Operation Under Rainy or Humid Conditions.
(1) Keep fuel tank cap secured. Keep access door closed. During handling of fuel, PMCS,
and refueling, be sure that water is not allowed to enter fuel or lubrication system.
(2) Take special care to prevent rust and corrosion. If surfaces become rusty or corroded,
remove corrosion, prime, and paint as necessary.
f. Operation in Saltwater Areas. Salt water causes corrosion. Use fresh water to wash off any
salt that comes in contact with the equipment.
a. Loss of suction requires shutdown of the Diesel-Driven Centrifugal Pump.
CAUTION
Do not suddenly stop running engine since it may cause engine
temperature to increase abnormally high, and possibly result in
engine damage. To stop the engine, gradually reduce load and
allow engine to run at idle speed for three minutes.
Do not stop engine using the decompression lever, or engine
damage may result. If engine cannot be stopped using the
speed control lever knob, move fuel cock handle horizontally to
the closed position.
(1) Slowly move engine speed control handle upward until engine is running at idle speed.
Allow engine to run at idle speed for three minutes.
(2) Close any discharge valves, then any suction valves that are installed in the hoses. This
will retain liquid in pump volute and reduce or eliminate priming requirements for the next
pumping application.
(3) Move engine speed control handle all the way to the STOP position.
