Re-tensioning the Chain
When working with the chainsaw, the chain (6) expands as a result of the heat generated.
With the chain (6) expanding, the tension slackens and the chain (6) can slip off the
guide bar (7).
If the chain (6) is tensioned in this condition, it is very important to release the tension
once cutting is completed, otherwise the chain (6) may contract so much on cooling, it
will be excessively tight.
Chain Brake
The chainsaw is fitted with a hand guard/chain brake
(5) which brings the chain (6) to a stop within a tenth
of a second. The hand guard/chain brake (5) is
actuated either manually or while operating as a result
of kickback, the hand guard/chain brake (5)(Fig. 8) is
pushed forward by the back of your hand engaging
the chain brake. To use the chainsaw again, you must
disengage the chain brake, to do this you should pull
the hand guard/chain brake (5) back towards you.
Note:
When the chain brake has been actuated
DO NOT RUN THE MOTOR OF
THE CHAINSAW.
Set the hand guard/chain brake (5) back to its original position, by
pulling the hand guard/chain brake (5) towards the front handle (4).
Note:
If the motor is running and the chain (6) is not turning, turn off the chainsaw and
check the chain brake is not engaged, if it is, disengage the chain brake and try again.
Each time you are about to use the the chainsaw, check it is in perfect working
condition. It is particularly important to ensure the guide bar (7) is properly fitted, the
chain (6) is correctly tensioned and the chain brake is functioning correctly.
CAUTION!
When working with the chainsaw, care should be taken to keep the
power and extension cord away from the chain (6).
Cutting Logs, Branches, etc.
CAUTION!
Position the power and extension cord so that it will not get caught
on tree branches and foliage during cutting.
Guide the chainsaw so no part of your body extends beyond the line of the guide bar (7).
Press the bucking spikes against the timber ensuring the chain (6) is NOT making
contact with the material being cut, only then start cutting by holding the chainsaw by
the front handle (4) and raising the rear handle (1). If you cannot cut the timber in a single
stroke, apply light pressure to the front handle (4) and continue sawing, draw the
chainsaw back a little then apply the bucking spikes a little lower and finish the cut by
raising the rear handle (1).
Withdraw the chainsaw from the cut while the chain (6) is still running.
