Adjusting the carburetor
The carburetor has been carefully set at the factory. Adjustment may be necessary if
you notice that the engine does not idle (e.g. the saw chain (3) keeps running when the
throttle trigger (10) is released). Contact an authorised service centre or dealer to do
idle speed adjustment.
WARNING! Keep others away when making idle speed adjustment. Keep
the saw chain (3) off the ground and ensure that it does not contact with any
object. The saw chain (3) will be running during this procedure. Wear personal
protective equipment and observe all safety precautions.
1. Release the throttle trigger (10) and allow the engine to idle.
2. Turn the idle speed screw clockwise using the screwdriver (28) to increase engine
speed if engine stalls or dies in idle mode (Fig. 50).
3. Turn idle speed screw anticlockwise using the screwdriver (28) to decrease engine
speed if the cutting attachment runs in idle mode.
