MAINTENANCE
Checking, maintaining and servicing 
chain saw safety equipment
Chain brake and front hand guard
Checking brake band wear
Brush off any wood dust, resin and dirt from the chain brake 
and clutch drum. Dirt and wear can impair operation of the 
brake.
Regularly check that the brake band is at least 0.6 mm (0,024 
inch) thick at its thinnest point.
Checking the front hand guard
Make sure the front hand guard is not damaged and that there 
are no visible defects such as cracks.
Move the front hand guard forwards and back to make sure it 
moves freely and that it is securely anchored to the clutch 
cover.
Checking the brake trigger
Place the chain saw on firm ground and start it. Make sure the 
chain does not touch the ground or any other object. See the 
instructions under the heading Start and stop.
Grasp the chain saw firmly, wrapping your fingers and thumbs 
around the handles.
Apply full throttle and activate the chain brake by tilting your 
left wrist forward onto the front hand guard. Do not let go of 
the front handle. The chain should stop immediately.
Throttle lock
Make sure the throttle control is locked at the idle setting 
when the throttle lock is released.
Press the throttle lock and make sure it returns to its 
original position when you release it.
Check that the throttle control and throttle lock move freely 
and that the return springs work properly.
Start the chain saw and apply full throttle. Release the 
throttle control and check that the chain stops and 
remains stationary. If the chain rotates when the throttle 
control is in the idle position you should check the 
carburetor idle adjustment.
Note! All servicing and repair work on the machine requires 
special training. This is especially true of the machine
′s 
safety equipment. If your machine fails any of the checks 
described below we recommend you to contact our 
servicing dealer.
