Braking System
This STIHL chainsaw is equipped with a chain brake system that can be activated in three different ways. As before, the chain brake can be activated by the inertia of the front hand guard in certain kickback situations or manually by pushing the front hand guard toward the bar nose. In both of these cases the brake, once activated, is designed to bring the chain to a standstill within fractions of a second. In addition, there is a secondary system that is designed to stop chain rotation within a second of you letting go of the rear handle. The locked chain is not released again until you press down the throttle trigger interlock lever to operate the throttle.
The chain brake can be activated in three ways:

The activating mechanism for the secondary chain braking system is integrated in the throttle trigger interlock lever (rear handle). One of the big advantages of this system is that the saw chain is automatically locked in position for engine starts and when carrying the running saw by the front handle (with the rear handle released).
To reduce the risk of personal injury or property damage during cutting, observe the characteristics that make this saw different from saws not equipped with a secondary chain braking system. Before operating the chainsaw for the first time, make sure you are familiar with how the
