Care and maintenance
4. Check the spark plug for damage and wear. The
colour of the ground electrode should be light-
brown.
5. Remove the deposits from the electrode with
a soft wired brush. Avoid heavy cleaning of the
electrode.
6. Dry the spark plug with a soft cloth, if it is wet
from fuel.
7. Check the spark plug gap. It should be 0.6-0.7 mm
(Fig. 49).
8. Replace with a new spark plug if either the
electrode or the insulation is damaged.
9. When replacing the spark plug, first screw it in
hand tight and then lightly tighten it with the multi-
tool.
NOTE: Do not over tighten the spark plug to avoid any damage!
10. Refit the spark plug connector (6a), attach the top cover (6) and secure it with the
fixing screw.
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 a screwdriver (28) to increase engine
speed if engine stalls or dies in idle mode (Fig. 50).
3. Turn idle speed screw anticlockwise using a screwdriver (28) to decrease engine
speed if the cutting attachment runs in idle mode.
