GENERAL SAFETY PRECAUTIONS

!

WARNING! 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. Such 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. These

 

symptoms may be increased in cold

 

temperatures.

Stop switch

Use the stop switch to switch off the engine.

Muffler

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

!

WARNING! The exhaust fumes from the

engine are hot and may contain sparks

 

 

which can start a fire. Never start the

 

machine indoors or near combustible

 

material!

In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor mesh.

CAUTION! The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.

WARNING! Never use a saw without a

! muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:

•Reduce the risk of kickback.

•Reduce the risk of the saw chain breaking or jumping off the bar.

•Obtain optimal cutting performance.

•Extend the life of cutting equipment.

•Avoid increasing vibration levels.

General rules

•Only use cutting equipment recommended by us! See instructions under the heading Technical data.

•Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.

•Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.

•Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.

•Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
