SAFETY INSTRUCTIONS

1 Chain brake and front hand guard

YOUR chain saw is equipped with a chain brake that is desig- ned to stop the chain immediately if you get a kickback.

The chain brake reduces the risk of accidents, but only You can prevent them.

Take care when using your saw and make sure the kickback zone of the bar never touches any object.

3a Starting

The chain brake must be engaged when the chain saw is started.

bYou can also use the chain brake as a temporary brake when you change position or if you put the saw down for a short time. You should also apply the chain brake manually if there is a risk of the chain accidentally hitting anyone or anything close by.

1The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism (a free- swinging pendulum). On most of our models the front hand guard acts as a counterweight in case of kickback.

The brake is applied when the front hand guard (B) is pushed forwards or when the right-hand brake trigger

(E)is pushed up and forwards.

This movement activates

aspring-loaded mechanism that tightens the Brake Band (C) around the engine drive system (D) (Clutch Drum).

4To release the chain brake pull the front hand guard backwards, towards the front handle.

5As mentioned in section A, 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.

2The front hand guard is not designed solely to activate the chain brake. Another important safety feature is that it prevents the chain from hitting your left hand if you lose your grip on the front handle.
