To tension the chain
WARNING: A saw chain with an incorrect
tension can derail from the guide bar and

A saw chain becomes longer when you use it. Adjust the
saw chain regularly.

brake. Use a wrench.
2. Tighten the bar nuts by hand as tightly as you can.
3. Lift the front of the guide bar and turn the chain
tensioning screw. Use a wrench.
4. Tighten the saw chain until it is tight against the
guide bar but still can move easily.

To check the chain lubrication
1. Check the chain lubrication each time you refuel.

about 20 cm (8 inches) away. After 1 minute running
at 75 % throttle you should see a distinct line of oil
on the light surface.
