Chain brake operation (Fig. 2, 11)
Chain brake is designed to activate in an emergency such as kick-
back action.
Application of brake is made by moving the front hand guard towards
the bar. During the chain brake operation, even if the throttle lever
is pulled, the engine speed does not increase and the chain does
not turn. To release the brake, pull the front hand guard toward the
front handle.
If the engine keeps rotating at high speed with the brake engaged,
the clutch will overheat causing trouble.
When the brake engages during operation, immediately release the
throttle lever to slow down the engine.

o
ff
the engine.
2) Holding the chain saw horizontally, release your hand from the
front handle, hit the tip of the guide bar to a stump or a piece
of wood, and con
fi
rm brake operation. Operating level varies by
bar size.
In case the brake is not e
ff
ective, ask our dealer for inspection and
repairs.
