Operation
Chain brake
1.
The chain brake's function is to stop chain rotation after a
kickback.
2.
It neither prevents nor reduces kickback.
3.
Do not depend on the chain brake for protection against kick-
back.
4.
Even with a chain brake, depend on your own good sense
and proper cutting methods just as though there were no
chain brake.
5.
Even with normal use and proper maintenance, the re-
sponse time of the brake may lengthen.
6.
The following may interfere with the brake's ability to protect
the operator:
Saw wrongly held too close to operator's body. Kickback time
may be too fast even for a perfectly maintained brake to work
in time.
The operator's hand may not be in position to contact the front
hand guard. Brake will not be tripped.
Lack of proper maintenance lengthens the brake's stopping
time, making it less effective.
Dirt, grease, oil, pitch, etc. getting into the working parts of the
mechanism may lengthen the stopping time.
Wear and fatigue of the activating brake spring, and wear of
the brake / brake drum and pivot points may lengthen the
brake's stopping time.
A damaged front hand guard may render the brake inopera-
tive.
Checking the brake function of the brake
1.
Place the chain saw on the ground.
2.
Hold the handle with both hands and accelerate the motor to
high speed by using the trigger switch.
3.
Operate the chain brake by turning your left wrist against the
front hand guard whilst gripping the front handle.
4.
The chain stop immediately.
5.
Release the trigger switch.
If the chain does not stop immediately, take the chain saw to
your ECHO dealer to repair.
Release the chain brake
When front hand guard is fully pulled rearward, chain brake is
released.
