Adjusting Idle Speed - Makita PM7651H Original Instruction Manual

NOTE:
The engine may be damaged if the choke lever is moved further beyond the "CLOSE" position.
●
If the engine stops with an explosion sound or if the engine started, but stopped before operation of the choke lever, return it to the "OPEN"
●
position and pull the starter handle several times to start the engine again.
If the operator keeps pulling the starter handle several times with the choke lever left in the "CLOSE" position, the engine may be difficult to
●
start because of over-suction of the fuel.
In case of over-suction of the fuel, remove the spark plug and pull the handle several times rapidly to discharge any excess fuel. Dry the spark
●
plug electrode.
When the throttle valve does not return to a position in contact with the idling adjusting screw even if the throttle trigger is set to the low speed,
●
correct the control cable catching state to ensure proper return of the valve.
2) When the engine is warm (warm start)
(1) Place the engine on a flat ground.
(2) Press the primer pump several times.
(3) Make sure that the choke lever is down.
(4) Hold the air cleaner cover with a left hand to prevent the engine from moving, settle down to take the stable position.
(5) Pull the starter handle slowly until feeling compression. Then pull it strongly.
(6) When the engine is difficult to start, open the throttle valve by 1/3.
2. Stopping
1) Release the throttle trigger to reduce the engine speed, and set the stop
control lever to the "O" position.
