Close the choke lever. Choke opening:

–Full closing in cold or when the engine is cold.

–Full or half opening in restart just after stop of operation.

3)Primer pump

Continue to push the primer pump until fuel enters into the primer pump. (In general, fuel enters into the primer pump by 7 to 10 pushes.)

–Never pull the rope to the full. Once the start knob is pulled, never release your hand immediately. Hold the start knob until it returns to its original point.

5)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.

Note: – If the starter handle is pulled repeatedly when the choke lever remains at “START” 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 or more. Never operate the engine at a higher speed than required and at an approximate speed of 6,000 - 8,500/min.
