Chain brake and front hand guard
Your product has a chain brake that stops the saw chain
if you get a kickback. The chain brake decreases the
risk of accidents, but only you can prevent them.
The chain brake engages (A) manually by your left hand
or automatically by the inertia release mechanism. Push
the front hand guard (B) forward to engage the chain
brake manually.
Pull the front hand guard rearward to disengage the
chain brake.
Throttle trigger lockout
The throttle trigger lockout prevents accidental operation
of the throttle trigger. If you put your hand around
the handle and press the throttle trigger lockout (A),
it releases the throttle trigger (B). If you release the
handle, the throttle trigger and the throttle trigger lockout
move back to their initial positions. This function locks
the throttle trigger at idle speed.

the handles. Vibration damping units operate as a
separation between the product body and the handle
