At times, such as winter, when starting the engine
is difficult
Operate choke lever with the following procedure when starting engine.
• After implementing startup steps 1) to 3), set choke lever to the CLOSE
position.
• Implement startup step 4) and start engine.
• Once engine starts, set choke lever to the OPEN position.
• Implement startup step 5) and complete warm up.
CAUTION: If a bang (explosive sound) is heard and the engine stops, or
the just-started engine stalls before the choke lever is operated,
return the choke lever to the OPEN position, and pull the starter
knob a few times again to start the engine.
CAUTION: If the choke lever is left in the CLOSE position, and the starter
knob merely pulled repeatedly, too much fuel will be sucked in,
and the engine will become difficult to start.
STOPPING
1) Release the throttle lever (2) fully, and when the engine rpm has lowered,
set the I-O switch to STOP the engine will now stop.
2) Be aware that the cutting head may not stop immediately and allow it to
slow down fully.
ADJUSTMENT OF LOW-SPEED ROTATION (IDLING)
When it is necessary to adjust the low-speed rotation (idling), perform it by the carburetor adjusting screw.
CHECKUP OF LOW-SPEED ROTATION
– Set the low-speed rotation to 3,000 min
If it is necessary to change the low speed rotation (idle) speed, use a phillips
head screw driver on the screw illustrated on the right.
– Turn the adjusting screw to the right, and the engine rotation will increase.
Turn the adjusting screw to the left, and the engine rotation will drop.
– The carburetor is generally adjusted before shipment. After several tanks of
gasoline the idle rpm may need to be readjusted.
THE NYLON CUTTING HEAD
During operation, use the tip of the nylon cutting cord for cut.
Feeding the nylon cutting cord
As the nylon cutting cord is worn and shortened with the cutting operation, the
operator needs to feed it manually.
To feed the nylon cutting cord, tap the nylon cutting head on the ground while it
rotates around 6,000 min .
