Hot Restart
To start an engine that is already warmed up (hot
restart), or if the ambient temperature exceeds 68°F
(20°C):
1.
Pump the primer bulb at the bottom of the carbu-
retor until fuel can be seen flowing through the
fuel return line to the fuel tank.
2.
Move the choke lever to the open (
) position
and move the stop switch to the “ON” position.
3.
Leave the throttle lever in the idle position and
pull the starter grip.
4.
If the engine fails to start after three to four pulls,
follow the instruction in the Cold Starting
Procedure section (page 18).
If the engine fails to start after you follow the
above procedures, contact an authorized
Maruyama dealer.
To Stop The Engine:
1.
Move throttle lever to the idle position.
2.
Move the stop switch to the “OFF” position.
IMPORTANT: Except emergency, do not stop
engine while it runs fast. It may damage the
engine. Move the throttle lever at idle position
first, then move the stop switch to “OFF” posi-
tion.
IMPORTANT: In case of the stop switch failure
and the engine continue to run, move the choke
lever to the closed (
) position to stop the
engine.
Carburetor Adjustment
This water pump is equipped with non-adjustable fuel
mixture carburetor. The engine idle speed is the only
adjustment accessible to the Operator.
CAUTION: The water pump impeller is spinning during
idle speed adjustment.
Never start the engine without water in the pump hous-
ing.
Running the engine without water in the pump housing
will cause serious damage.
Engine Idle Speed:
The engine idle speed should be 2,700-3,300 rpm.
The engine idle speed is adjusted by rotating the idle
speed screw on the carburetor.
Turning the idle speed screw in (clockwise) increase
engine speed while turning the screw out decreases
engine speed.
