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 reduce
the risk of kickback injury, it must be properly maintained
and in good working order, @ 6.2.
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.
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.
NOTICE
High revs with the chain brake engaged will quickly damage
the powerhead and chain drive (clutch, chain brake). Always
disengage chain brake before accelerating the engine and
before starting work.
