Another important safety feature is that it prevents the chain from hitting your left hand if you lose your grip on the front handle. 3 You can also use the chain brake as a temporary brake when you change position or if you put the saw down[...]

6 – English 6 The 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.

English – 7 4 Vibration damping system Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations in the handles and make operation easier.
