damaged.

5

Check that all handles are free from oil.

6

Check that the anti vibration system works and is not 
damaged.

7

Check that the muffler is securely attached and not 
damaged.

8

Check that all parts of the chain saw are tightened 
correctly and that they are not damaged or missing.

General working instructions

Basic safety rules

1

Look around you:

To ensure that people, animals or other things cannot 
affect your control of the machine.

To make sure that none of the above might come 
within reach of your saw or be injured by falling trees.

CAUTION! Follow the instructions above, but do not use a 
chain saw in a situation where you cannot call for help in 
case of an accident.

2

Do not use the machine in bad weather, such as 
dense fog, heavy rain, strong wind, intense cold, etc. 
Working in bad weather is tiring and often brings 
added risks, such as icy ground, unpredictable felling 
direction, etc.

3

Take great care when removing small branches and 
avoid cutting bushes (i.e. cutting many small branches 
at the same time). Small branches can be grabbed by 
the chain and thrown back at you, causing serious 
injury.

4

Make sure you can move and stand safely. Check the 
area around you for possible obstacles (roots, rocks, 
branches, ditches, etc.) in case you have to move 
suddenly. Take great care when working on sloping 
ground.

5

Take great care when cutting a tree that is in tension. 
A tree that is in tension may spring back to its normal 
position before or after being cut. If you position 
yourself incorrectly or make the cut in the wrong place 
the tree may hit you or the machine and cause you to 

IMPORTANT!

This section describes basic safety rules for using a 
chain saw. This information is never a substitute for 
professional skills and experience. If you get into a 
situation where you feel unsafe, stop and seek expert 
advice. Contact your chain saw dealer, service agent or 
an experienced chain saw user. Do not attempt any task 
that you feel unsure of!

Before using a chain saw you must understand the 
effects of kickback and how to avoid them. See 
instructions under the heading How to avoid kickback.

Before using a chain saw you must understand the 
difference between cutting with the top and bottom 
edges of the bar. See instructions under the headings 
How to avoid kickback and Machine’s safety equipment.

Wear personal protective equipment. See instructions 
under the heading ”Personal protective equipment”.
