@ 6.2.

WARNING
No chain brake device prevents kickback. This device is
designed to reduce the risk of kickback injury, if activated, in
certain kickback situations. For the chain brake to remain in
good working order, it must be properly maintained, @ 9.
In the event of a kickback, the chain brake is designed to
engage if the left hand contacts the front hand guard and
pushes it forward.
The chain brake is also designed to be activated by the
inertia of the front hand guard if the forces are sufficiently
high. When the brake is activated by inertia, the hand guard
accelerates toward the bar nose, even if your hand is not
behind the hand guard, e.g., during a felling back cut.
Engaging the chain brake locks the chain. To manually
engage the chain brake:
► Push the front hand guard away from the front handle.
You will hear an audible click when the front hand guard
reaches the locked position. If the chain saw is switched on
and the saw is in standby mode, the "CHAIN BRAKE" LED
(1) lights up.

14.2 Disengaging the Chain Brake

WARNING
Before disengaging the chain brake and switching on your
chain saw, be sure that the guide bar and saw chain are
clear of you and all other obstructions and objects, including
the ground, @ 5.5.
