OPERATOR INSTRUCTIONS
INITIAL START-UP OR START-UP WITH THE SYSTEM FULLY DRAINED
OPERATION UNDER USUAL CONDITIONS
WARNING
Combustion hazard. Fuel the diesel engine in a well ventilated area with the engine
stopped. Do not smoke or allow flames or sparks in the area where the engine is fueled or
where the fuel is stored. Failure to observe this warning may result in fire and severe
injury.
Combustion hazard. Do not overfill the fuel tank. Make sure the filler cap is securely
closed after fueling. Be careful not to spill fuel when fueling. If any fuel is spilled, make
sure the area is dry before starting the engine. Failure to observe this warning may result
in fire and severe injury.
CAUTION
Potential for engine damage. The diesel engine may be damaged if operated with
insufficient lube oil. It is also dangerous to supply too much lube oil to the engine
because a sudden increase in engine rpm could be caused by its combustion. Failure to
observe this caution may result in engine damage.
Potential for engine damage. Only use the correct diesel fuel. Use of the wrong fuel may
cause engine damage.
When adding fuel to the fuel tank, be careful not to push the fuel screen filter into the tank.
5. Before starting the diesel engine pump, check the diesel fuel level and engine oil levels in
accordance with the PMCS schedule, WP 0038. When checking the oil level, make sure the
engine is on a level surface with the engine stopped.
6. Start the diesel engine using the following procedure (see Figure 5).
a. Set the fuel cock clockwise to the OPEN position.
b. Put the engine speed lever in the START Position.
c. Slowly pull out the recoil-starting handle until you feel strong resistance, then return it to
the initial position.
d. Push down the decompression lever. If the lever does not stay down by itself, it may be
necessary to pull the recoil starting handle out a little more. The decompression lever will
return to the up position automatically when the recoil starter is pulled all the way out to
start the engine.
e. Pull out the recoil starting handle briskly with both hands to start the engine
f. If the engine fails to start; return to step c (initial start of a new engine may require 6 or
more pulls to clear the air from the fuel lines.)
g. Move the engine speed lever to a middle position to reduce the engine speed to idle.
7. Warm up the engine at idle for about three (3) minutes. Then set the speed lever to START.
8. The pump will draw the air out of the suction hose and pump it through the open Vent Valve V-
102 and the vent hose. As the air is removed the water follows.
9. When pressurized water is observed discharging from the vent hose, the pump is primed. Close
Vent Valve V-102.
