The chain brake is a device which stops the chain should the
chainsaw recoil due to kickback. Normally, the brake is
activated automatically by inertial force, however it can also be
activated manually by pressing the brake lever forward / away
from you.
TO RELEASE THE BRAKE
Release the chain brake by pulling the handle towards you
when holding the saw. Some force maybe required to
disengage the brake. This is to prevent the accidental
releasing of the brake while in use.
TO ENGAGE THE BRAKE
Engage the brake by pushing the brake handle away from you
when holding the saw. The brake is spring loaded so after some
initial force the brake will move forward on its own momentum.
If the brake operates during use immediately release the
throttle to reduce engine speed and when deemed safe release
the brake and resume us

CHAIN BRAKE
Continuous operation while the brake is
engaged will generate excessive heat, which
can melt the brake assembly and damage
the clutch.

CORRECT USE OF CHAIN BRAKE
The following will help maintain the chain brake's ability to protect the
operator
•
Always check whether the brake works properly before each
task.
•
If the chain brake is clogged with wood chips the effectiveness
of the brake is diminished.
•
Always keep the device clean and free of debris.
•
Do not use the throttle while the chain brake is engaged.
•
Chain brake is to be used in emergencies.
•
Do not use it unless absolutely necessary.
•
After starting the engine, release the brake immediately.
•
Never test the brake in an area where petrol fumes are present.
INCORRECT USE OF CHAIN BRAKE
The following may interfere with the chain brake's ability to protect the
operator:
•
Chainsaw incorrectly 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 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 / clutch drum and pivot points may lengthen the brake's
stopping time.
•
A damaged hand guard and lever may render the brake inoperative.
WARNING! Always check that chain brake is fully functional before starting or using the chainsaw.
WARNING! If the chain brake is defective in anyway do not use the chainsaw
