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
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 inertia brake release
Place the chain saw, with the engine switched off, on a
stump or other stable surface. Release the front handle
and let the saw fall by its own weight, rotating around the
rear handle towards the stump.
When the bar hits the stump the brake should be
applied.
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.
Note! All service and repair work on the machine
demands special training. This is especially true of the
machine’s safety equipment. If your machine fails any of
the checks described below we recommend that you
take it to your service workshop.
