16.1 Engaging the Chain Brake

WARNING
The chain brake will operate only if it has been properly
maintained and the front hand guard has not been modified,
@ 7.2.
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, @ 7.2.
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.
