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.
WARNING: Do not engage in situations
where there is a risk of kickback. Be careful
when you use your product and make sure
that the kickback zone of the guide bar does
not touch an object.
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. This movement starts a spring-loaded
mechanism that stops the drive sprocket.
How the chain brake is engaged depends on the force of
the kickback. It also depends on the position of the
product when the kickback zone hits an object. If you get
a intense kickback while the kickback zone is farthest
away from you the chain brake engages by the inertia
release. If the kickback is small or the kickback zone is
805 - 002 -
B
A
nearer you the chain brake engages manually by your
left hand.
Use the chain brake as a parking brake when you start
the product and when you move short distances. This
decreases the risk that you or a person near you get hit
by the saw chain.
Pull the front hand guard rearward to disengage the
chain brake.
A kickback can be very sudden and intense. Most
kickbacks are small and do not always engage the chain
