Chain Brake

Chain brake

Your saw is equipped with a chain brake which can be activated both manually and by the force of inertia. The chain brake consists of the front hand guard, an activating mechanism,

a spring and a brake band encircling the clutch drum.

When the front hand guard is moved foreward, the mechanism releases the spring, jerking the band tight around the clutch drum. When activated, the chain brake is designed to stop a rotating chain instantaneously. The chain brake is activated when the front hand guard is pushed foreward (1). If the chain brake has been activated, it is disengaged by pulling the front hand guard back towards the front handle (2). The chain brake must be disengaged when the saw is running.

Manual activation

Move the front hand guard foreward until the chain brake «clicks on».

Inertia activation

If your chain saw is suddenly pushed rearward with sufficient force, the sudden movement can activate the chain brake.

The advantage of inerta activation is that a kickback (see p. 20) can have enough force to activate the chain brake without the left hand having to touch the front hand guard.
