6) Choke lever
When the engine starts, open the choke lever.
– Open the choke lever progressively while checking the engine operation.
Be sure to open the choke lever to the full in the end.
– In cold or when the engine is cooled down, never open the choke lever
suddenly. Otherwise, the engine may stop.
7) Warm-up operation
Continue warm-up operation for 2 to 3 minutes.
Note: – If the starter handle is pulled repeatedly when the choke lever remains at "CLOSE" position, the engine will not start easily due to
excessive fuel intake.
– In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess fuel. Also, dry the electrode
section of the spark plug.
Caution during operation:
If the throttle lever is opened fully in a no-load operation, the engine rotation is increased to 10,000 min
higher speed than required and at an approximate speed of 6,000 - 8,500 min
B: Startup after warm-up operation
1) Push the primer pump repeatedly.
2) Keep the throttle lever at the idling position.

When the unit is turned off, make sure the cutting attachment has stopped
before the unit is set down.
– Set the low-speed rotation to 3,000 min
If it is necessary to change the rotation speed, regulate the adjusting screw
(illustrated on the right), with Phillips screwdriver.
– 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.
