Warming Up
●
After starting the engine, run
the engine at the idling speed
(throttle lever position is fully
CLOSED) for a few minutes.
NOTICE
Allow sufficient warm-up time to prevent engine damage
and run the engine smoothly. The engine should be run
at idle speed for a few minutes to allow it to warm up
before applying a load. This will allow oil to reach
engine parts, and allow piston clearance to reach design
specifications.
NOTE
○
If it is necessary to restart the engine, do so one minute later
after the engine has been shut off.
When restarting warmed engine
●
Set the lift up lever to the “RUNNING” position and then pull
the recoil starter grip.
Idling Speed Adjustment
●
If the cutting blade move when
the engine is running at the
idle speed, turn the idle screw
counterclockwise to decrease
the engine idle speed.
●
If the engine does not run the
idle speed, it may be changed
too low, turn the idle screw
clockwise to increase the
engine idle speed.
The stable idling speed is about 3000 r/min (rpm).
Fuel Adjustment
●
The carburetor has been adjusted to the optimum fuel supply
at the factory. Don’t reset the carburetor setting.
NOTE
○
If adjustment is needed, it should be performed by your
authorized equipment dealer.
Stopping the Engine
NOTICE
Suddenly stopping engine from high-speed operation
can cause engine damage. Reduce engine speed to idle
speed for one minute before shutting engine off after
high-speed, full-load operation.
Ordinary Stop
●
Move the throttle lever on the
equipment to the fully
CLOSED (engine idle speed)
position, and the engine
running at idle speed.
●
Turn the engine switch to the
“STOP” position.
