SAFETY INSTRUCTIONS

7 Muffler

Never use a chain saw that has a faulty muffler.

Regularly check that the muffler is securely attached to the chain saw.

If the muffler on your saw is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.

Never use a muffler if the spark arrestor mesh is missing or defective.

!NEVER USE A CHAIN SAW WITH FAULTY SAFETY EQUIPMENT. CARRY OUT THE CHECKS AND MAINTENANCE MEASURES DESCRIBED IN THIS SECTION. IF YOUR CHAIN SAW FAILS ANY OF THESE CHECKS CONTACT YOUR SERVICE AGENT TO GET IT REPAIRED.

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 chain breaking or jumping.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

The 5 basic rules

1 Only use cutting equipment recommended by us! See the ”Technical data” section.

2Keep the chain cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.

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

4Keep the chain properly

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

5Keep 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.
