Chain Brake - Jonsered 2116 EL Operator's Manual

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.
