GENERAL SAFETY PRECAUTIONS

• The chain brake (A) can either be activated manually (by

your left hand) or automatically by the inertia release

mechanism.

• The brake is applied when the front hand guard (B) is

pushed forwards.

• This movement activates a spring-loaded mechanism that

tightens the brake band (C) around the engine drive

system (D) (clutch drum).

• The front hand guard is not designed solely to activate the

chain brake. Another important feature is that it reduces

the risk of the chain hitting your left hand if you lose grip of

the front handle.

• The chain brake must be engaged when the chain saw is

started to prevent the saw chain from rotating.

• Use the chain brake as a ”parking brake” when starting

and when moving over short distances, to reduce the risk

of moving chain accidentally hitting your leg or anyone or

anything close by.

• To release the chain brake pull the front hand guard

backwards, towards the front handle.

• Kickback can be very sudden and violent. Most kickbacks

are minor and do not always activate the chain brake. If

this happens you should hold the chain saw ﬁrmly and not

let go.

• The way the chain brake is activated, either manually or

automatically by the inertia release mechanism, depends

on the force of the kickback and the position of the chain

saw in relation to the object that the kickback zone of the

bar strikes.

If you get a violent kickback while the kickback zone of the

bar is farthest away from you the chain brake is designed

to be activated by the inertia in the kickback direction.

If the kickback is less violent or the kickback zone of the

bar is closer to you the chain brake is designed to be

activated manually by the movement of your left hand.
