Apart from protecting your hand if the chain jumps or 
snaps, the right hand guard stops branches and twigs 
from interfering with your grip on the rear handle. (11)

Your machine is equipped with a vibration damping 
system that is designed to reduce vibration and make 
operation easier.

The machine

′s vibration damping system reduces the 

transfer of vibration between the engine unit/cutting 
equipment and the machine

′s handle unit. The body of the 

chain saw, including the cutting equipment, is insulated 
from the handles by vibration damping units.

Cutting hardwoods (most broadleaf trees) creates more 
vibration than cutting softwoods (most conifers). Cutting 
with cutting equipment that is blunt or faulty (wrong type 
or badly sharpened) will increase the vibration level.

Use the stop switch to switch off the engine. (12)

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

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 screen.

When fitting the mesh, make sure that the mesh is 
inserted in the right position.  If necessary, use the 
combination spanner to insert or remove the mesh.

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.

•

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.

The only way to avoid kickback is to make sure that the 
kickback zone of the bar never touches anything.

By using cutting equipment with ”built-in” kickback 
reduction and keeping the chain sharp and well-
maintained you can reduce the effects of kickback.

NB! 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.
