Checking the operation of the clutch.
Each time the chainsaw is started, the operation of the clutch (38) should
be checked as per the following detail. The chain MUST first be checked to
ensure correct tension adjustment before starting.
1. When attempting to start the chainsaw, the chain (20) should not be trying
to move around the guide bar (19) under the influence of the recoil starter
(11). If it is trying to rotate around the guide bar (19), STOP the starting
process and take the saw to an authorised service centre.
2. If point 1 is correct and the chain (20) is not trying to rotate around the
guide bar (19), start the chainsaw as per the section in the manual “Starting
the Chainsaw”.
3. With the chainsaw operating and at idle (throttle lock button (5) NOT
engaged), and ensuring the chain (20) is in a safe position with respect of
other persons and any objects, release the chain brake (13).
CHECK, the chain (20) should NOT be rotating around the guide bar (19) at
idle speed.
4. Operate the safety lever (2) and then accelerate the throttle trigger (3).
The chain (20) should start and rotate. The harder the throttle trigger (3)
is pulled, the faster the chain (20) will rotate. RELEASE the throttle trigger
(3) so the motor returns to the idle condition. The chain (20) MUST stop
rotating around the guide bar (19) when the motor of the saw is at idle.
5. If the chain (20) is constantly rotating when the motor of the saw is at idle,
the chainsaw should NOT be used and the chainsaw should be taken to an
authorised service centre for repair.
6. DO NOT use the chainsaw if the clutch (38) does not totally disengage
when the motor of the saw is at idle.
Re-setting the Chain Brake
The front guard / chain brake (13) operates automatically in the event of
kickback. In the event of a kickback, the guide bar (19) kicks up, the wrist of
the operator’s hand on the top handle knocks against the front guard / chain
brake (13) causing it to move forward thus activating the chain brake (13).
To reset the front guard / chain brake (13) this can be done manually by
pulling it firmly towards the back of the chainsaw until a click is heard. (Fig A).
CAUTION: Each time the chainsaw is used, check that the chain brake (13)
is operating correctly.
