CUTTERS EDGE FIRE RESCUE SAWS
Part One:
THE CHAIN BRAKE
The chain brake is designed to stop
the rotation of the chain in less than
one-twentieth of a second. If kickback
should occur, the violent reverse
action will actuate the inertia chain
brake (same principle as a car seat-
belt) or drive the chain brake handle
back into the operator's hand,
engaging the chain brake and
stopping the movement of the chain.
The chain brake has three posi-
tions:
Fig. 1. Center- operating position,
chain brake disengaged.
(Normal cutting position).
During operation, the brake is in the
neutral or center position (Fig.1).
This allows the chain to turn freely.
Fig. 2. Forward Position - chain
brake engaged
When engaged, the chain brake
handle is in the fully forward position
(Fig. 2). In this position the chain
will not turn.
Fig. 3. Back position - to disengage
chain brake
To disengage the chain brake, pull the
chain brake handle back completely
to the saw's top handle (Fig. 3).
It is important that the chain brake
handle comes into full contact with
the saw's handle. Any obstructions,
such as your hand, will prevent
disengagement of the chain brake.
Once you have pulled the chain brake
handle back completely, let go and it
will snap back to the center operating
position. (See Fig. 1)
