4.5.4- Chain brake
The chain brake is a device which stops the chain instantaneously if
the chain saw recoils due to kickback.
Normally, the brake is activated automatically by inertial force. It can
also be activated manually by pushing the brake lever (left-hand
guard) down toward the front.
Releasing the brake: pull the brake lever up toward the left-hand handle until it clicks into place.
WARNING - When the brake operates, release the throttle lever to slow down the engine
speed. Continuous operation with the brake engaged will generate heat from the
clutch and may cause trouble.
- At machine inspection prior to each job, check the operating condition of the
brake following the steps:
1. Start the engine and grasp the handle securely with both hands.
2. Pulling the throttle lever to maintain the chain operation, push the brake lever
(left-hand guard) down toward the front using the back of your left hand.
3. When the brake operates and the chain is stopped, release the throttle lever.
4. Release the brake.
4.5.5- Stopping the engine
1. Release the throttle lever to allow the engine to idle for a few minutes.
2. Set the main switch to "O" (STOP) position.
