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:
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 is in relation to the
force of the kickback and position of the product. If
you get an 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 nearer you, the chain brake engages manually
by your left hand.

Do not engage in situations

A
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
touches 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
