CHAIN BRAKE
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 disen-
gage 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 on momentum.
If the brake operates during use immediately release the throt-
tle to reduce engine speed and when deemed safe release the
brake and resume us e.
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
•
At all times, confirm whether the brake works properly before
each task.
• If the chain brake is clogged with wood chips the effectivness of
the brake is diminshed.
•
Always keep the device clean.
•
Do not increase engine revolutions while the chain brake is
engaged.
•
Chain brake is 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.
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 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 stop-
ping time.
•
A damaged hand guard and lever may render the brake inoperative.
Always check that chain brake works properly before use.
