Grasp the starter grip (Figure 10) and slowly pull it out. 13.
The resistance becomes the hardest at a certain
position, corresponding the compression point. Rewind
the rope a little from that point and pull out sharply.
Starter GripFigure 10.
If the engine has started, slowly return the choke lever 14.
(Figure 8) to the CLOSED position. If the engine has
not started repeat steps 1 through 5.
Before the pump is put into operation run the engine 15.
for 3-5 minutes.
NOTICE
The CLOSED position of the choke lever enriches the
fuel mixture for starting a COLD engine. The OPEN
position provides the correct fuel mixture for normal
operation after starting, and for restarting a warm
engine.

DO NOT release the starter rope after pulling. Allow it
to rewind as soon as possible.
Check for fuel leaks and noises that would be 16.
associated with a loose component.Check for leaks
between pump and engine. If water is leaking between
the pump and engine housing, the seal inside the
pump may be worn or damaged. Continued operation
of the pump is not recommended. Further usage of the
pump under these conditions may cause severe water
damage to engine.
OPERATION
Once the engine has started, move the engine throttle 1.
lever quickly to the fast position to begin pumping. If
water is not fl owing out of the discharge port, turn off
the engine and check for and clear any obstructions
within the suction hose.
STOPPING THE ENGINE
Place the throttle lever (Figure 9) in slow position, and 1.
listen for the engine speed to decrease.
Place the Engine ON/OFF switch (Figure 7) in the 2.
"OFF" position.
Place the fuel valve lever (Figure 6) in the "3. OFF"
position.
WARNING
Water must always be fl owing through the pump casing
while the engine is running. Loss of fl ow may be the
result of a loss of prime, restricted water fl ow or a dead-
head situation. Please note that in such a condition,
water in the pump can reach temperatures of 150-200°F
in 15 to 20 minutes. This can cause serious burns if
this hot water comes into contact with unprotected skin.
Before touching or opening the fi ll plug or drain plug,
fi rst turn off the engine and allow the pump casing to
cool to the touch, and then open the pump carefully.
Be cautious of any built up water pressure.
CAUTION
ALWAYS run engine at full speed while pumping.
