SAFETY INSTRUCTIONS

5 Vibration damping system

Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations and make operation easier.

When you use a chain saw vibrations are generated by the uneven contact between the chain and the wood you are cutting.

Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with a chain that is blunt or faulty (wrong type or badly sharpened, see section

D)will increase the vibration level.

The vibration damping system reduces the vibrations transmitted from the engine and chain to the handles of the chain saw. The body of the saw, including the cutting equipment, is insulated from the handles by vibration damping units.

Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation.

Contact your doctor if you experience symptoms of overexposure to vibration. These symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists.

6 Stop switch

Use the stop switch to switch off the engine.

7 Muffler

The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

The exhaust fumes from the engine are very hot and may contain sparks which can start a fire. Never start the saw indoors or near combustible material!

In areas with a hot, dry climate there is a high risk of forest fires. These areas are sometimes controlled by legislation and requirements that among other things the muffler must be equipped with an approved type of spark arrestor mesh.

For mufflers it is very important that you follow the instructions on checking, maintaining and servicing your saw (see the section on ”Inspecting, maintaining and servicing chain saw safety equipment”).

The muffler gets very hot in use and remains so for a short time afterwards. DO NOT TOUCH THE MUFFLER IF IT IS HOT!

WARNING!

The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapours.
