Vibration; Re-Setting Chain Brake - ALDI 50712 37CC User Manual

Operation
Checking the operation of the clutch.
Each time the chainsaw is started, the operation of the clutch (35) 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 (19) should not be trying
to move around the guide bar (18). If it is trying to rotate around the guide
bar (18), STOP the starting process and take the saw to an authorised
service centre.
2. If point 1 is correct and the chain (19) is not trying to rotate around the
guide bar (18), start the chainsaw as per the section in the manual "Starting
the Chainsaw".
3. With the chainsaw operating, and ensuring the chain (19) is in a safe
position with respect of other persons and any objects, release the chain
brake (12).
CHECK, the chain (19) should NOT be rotating around the guide bar (18).
4. Operate the safety lever (2) and then accelerate the throttle trigger (3).
The chain (19) should start and rotate. The harder the throttle trigger (3)
is pulled, the faster the chain (19) will rotate. RELEASE the throttle trigger
(3) so the motor returns to the idle condition. The chain (19) MUST stop
rotating around the guide bar (18) when the motor of the saw is at idle.
5. If the chain (19) 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 (35) does not totally disengage
when the motor of the saw is at idle.
Re-setting the Chain Brake
The front guard / chain brake (12) operates automatically in the event of
kickback. As the guide bar (18) kicks up, the wrist of the operator's hand on
the top handle knocks against the front guard / chain brake (12) causing it to
move forward thus activating the chain brake (12).
To reset the front guard / chain brake (12) this can be done manually by
pulling it firmly towards the back of the chainsaw until a click is heard. Some
generous force can be used as this is a firm operation and will require the
operator to pull back firmly. (Fig U)
CAUTION: Check that the chain brake (12) is operating correctly each time
the chainsaw is used.
