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 (Front handle
guard) down toward the front. When the brake operates, a white cone
pops up from the base of the brake lever. (1) Front handle (2) Release
