Stopping the engine
Release the throttle trigger, and then press down the combination switch to lower
(O) position.
The combination switch reverts to (I) position automatically. The engine stops with
this switch off, but is ready to start.
To cut off the ignition current, push the combination switch all the way down past the
resistance point to lock it at (O) position.
Adjusting idle speed
WARNING:
•
Do not adjust idle speed before the chain saw is completely assembled and
checked.
•
If the saw chain still moves at idle speed even after adjustment, stop using the
chain saw immediately, and bring it to Dolmar authorized service center for repair.
CAUTION:
•
Do not adjust the screws (H) and (L) in the illustration.
If the saw chain moves in idle without pulling throttle trigger, it is necessary to adjust
the idle speed.
Adjust the idle speed as follows:
1. Start and warm up the engine for two or three minutes, but do not drive the
engine at high speed.
2. To reduce the idle speed, turn the adjusting screw counterclockwise.
3. To increase the idle speed, turn the adjusting screw clockwise.
4. Make sure the saw chain does not move at idle speed.
Prevention from carburetor icing
NOTICE:
•
When environmental temperature is higher than 5°C, always return the shutter
to normal (sun mark) setting. Otherwise the engine may be damaged by
overheating.
When the environmental temperature is low (0°C - 5°C) and humidity is high, water
vapor may freeze inside the carburetor and the engine drives unsteadily (carburetor
icing). Change the setting of the shutter as follows if necessary.
1. Open the cleaner cover.
2. Pull out the shutter.
3. Set the shutter in anti-icing position (snow mark).
4. Return the cleaner cover.
