GENERAL SAFETY PRECAUTIONS

Locking nut

A locking nut is used to secure some types of cutting 
attachment.

When fitting, tighten the nut in the opposite direction to the 
direction of rotation of the cutting attachment. To remove it, 
undo the nut in the same direction as the cutting attachment 
rotates. (CAUTION! The nut has a left-hand thread.) Tighten 
the nut using the socket spanner.

When loosening and tightening the saw blade nut, there is a 
risk of injury from the teeth of the saw blade. You should 
therefore always ensure that your hand is shielded by the 
blade guard when doing this. Always use a socket spanner 
with a shaft that is long enough to allow this. The arrow in the 
diagram shows the area where you should operate the 
socket spanner when loosening or tightening the nut.

The nylon lining inside the locking nut must not be so worn 
that you can turn it by hand. The lining should offer a 
resistance of at least 1.5 Nm. The nut should be replaced 
after it has been put on approx. 10 times.

Cutting equipment

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

•

Reduce the risk of blade thrust.

•

Obtain maximum cutting performance.

•

Extend the life of cutting equipment.

Cutting equipment

Saw blades are intended for cutting fibrous types of wood.

Grass blades and grass cutters are intended for cutting 
coarse grass.

A trimmer head is intended for trimming grass.

IMPORTANT!

Only use cutting attachments with the guards we 
recommend! See the chapter on Technical data.

Refer to the instructions for the cutting attachment to check 
the correct way to load the cord and the correct cord 
diameter.

Keep the teeth of the blade correctly sharpened! Follow our 
recommendations. Also refer to the instructions on the 
blade packaging.

Maintain the correct blade setting! Follow our instructions 
and use the recommended file gauge.

!

WARNING! Always stop the engine before 
doing any work on the cutting attachment. 
This continues to rotate even after the 
throttle has been released. Ensure that the 
cutting attachment has stopped completely 
and disconnect the HT lead from the spark 
plug before you start to work on it.

!

WARNING! Using an incorrect cutting 
attachment or an incorrectly sharpened 
blade increases the risk of blade thrust.
