The saw is equipped with a chain brake. The brake is designed to
stop the chain immediately in the event of a kick-back.The brake
activates when the hand guard is pushed forward (1).
If the brake is already activated, it is disengaged by pulling the
front handguard back towards the front handle (2).
When working with the saw, the chain brake must be disengaged.
Usethe chain brake as a “parking brake”, if you move the saw
with the engine running.
Inertia activated chain brake
The inertia activatedchain brake is activated when the front hand
guard is pushedforward, either manuallyor by a weight in the
hand guard.
The advantageof the inertia brake is that the brake is activated
after kick-back, even if the user’s left hand does not contact the
hand guard, i.e., also when the saw is in the felling position.
