3. Main settings
a. Release of the chain brake
Release the chain brake by pulling the front hand guard firmly towards the back of
the electric chain saw, until a click is heard. To check the chain brake has been
released, you should be able to move the chain by hand.
b. Sharpening of the chain
For best performance, we strongly recommend that you periodically sharpen the
chain. The chain can either be sharpened by a professional or by yourself by
providing you with a sharpening guide (make sure you know how to use it).
The chain must be sharpened when:
- Wood chips have become powder
- To make a normal cut, force on the tool
- The cut is not straight
- Vibration increases
c. Checking the lubrication of the chain
Warning: Check the automatic oil function before each use.
Check the automatic operation of the chain lubrication by pointing the tip of the
switched –on saw towards a piece of paper laying on the ground, if a patch of oil
appears and becomes larger, then the automatic oil function is working.
