SAFETY INSTRUCTIONS

Inspecting, maintaining and servicing chain saw safety equipment

SPECIAL TRAINING IS REQUIRED to service and repair chain saws. This is especially true of chain saw safety equipment. If your chain saw fails any of the checks described below take it to your SERVICE AGENT.

When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your saw is not a SERVICING DEALER, ask him for the address of your nearest SERVICE AGENT.

1 Chain brake and front hand guard

1Checking brake band wear

Brush off any sawdust, 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

mmthick at its thinnest point.

2 Checking the front hand guard

3 Checking the inertia brake release

Hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar falls onto the stump.

When the bar hits the stump the brake should be applied.

4 Checking the right-hand brake trigger

A) Check that the right-hand brake trigger is undamaged and has no visible defects, such as cracks.

B) Push the trigger up and forwards to check that it moves freely and is securely hinged to the clutch cover.

Never carry or hang the saw by the trigger. This could damage the mechanism and disable the chain brake.

4 Checking the brake trigger

A Make sure the

FRONT HAND GUARD is not damaged and that there are no visible defects such as cracks.

B Move the front hand guard forwards and back to make sure it runs freely and that it is securely anchored to the clutch cover.

Place the chain saw on a firm surface 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 saw firmly, wrapping your fingers and thumbs around the handles.

Apply full throttle and activate the chain brake by tilting your wrist forward onto the front hand guard. Do not let go of the front handle.

The chain should stop immediately.
