SAFETY INSTRUCTIONS
6The way the chain brake is triggered, either manually or automatically, 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 will be activated by the movement of the counterweight (INERTIA ACTIVATED).
2 Throttle lock
The throttle lock is designed to prevent accidental opera- tion of the throttle control.
When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle trigger (B).
When you release the handle the throttle trigger and the throttle lock both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting when you release the handle.

B |
If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand.
7 During felling your left hand grasps the front handle in such a way that it cannot activate the front hand guard. In this position the chain brake can only be activated by the inertia action of the counterweight.
The inertia activated chain brake increases your safety but there are certain factors to remember (see point 6 above).
3 Chain catcher
The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see section on ”Assembly”) and if the bar and chain are properly serviced and maintained.
(See section on ”General working instructions”).
4 Right hand guard
Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.
