b. Chain brake
The chain brake is a device that automatically stops the chain in case a backward
movement occurs, causing the saw to jump. Normally, the brake is automatically
activated by the inertia force.
It is also manually tightened by pushing the brake lever down and forward.
When the brake is running, a yellow sign comes out from the base of the brake lever.
To release the brake, pull the brake lever up until it clicks into place.
When the brake is working, release the throttle lever to slow down the engine speed.
Continuous use when the brake is running causes the clutch to heat up and can cause
problems.
When checking the machine before using it, check the operating condition of the brake
by performing the following operations:
Start the engine and grasp the handle firmly with both hands.
▪
▪ While pulling the throttle control lever to keep the chain in operation, push the
brake lever down with the back of the left hand.
▪ When the brake is running and the chain is stopped, remove the hand from
the throttle.
▪ Loosen the brake.
c. Release of the chain brake
To use the chain saw again, the chain brake must be released. This must be done
machine off and cooled. Pull the shield until it returns to its original position.
