WORKING TECHNIQUES

Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting with a pulling chain gives the operator better control over the chain saw and the position of the kickback zone.

9Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data.

Basic cutting technique

WARNING! Never use a chain saw by

! holding it with one hand. A chain saw is not safely controlled with one hand. Always have a secure, firm grip around the handles with both hands.

General

•Always use full throttle when cutting!

•Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage).

•Cutting from above = Cutting with a pulling chain.

•Cutting from below = Cutting with pushing chain.

Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback.

Terms

Cutting = General term for cutting through wood.

Limbing = Cutting branches off a felled tree.

Splitting = When the object you are cutting breaks off before the cut is complete.

There are five important factors you should consider before making a cut:

1Make sure the cutting equipment will not jam in the cut.

2Make sure the object you are cutting will not split.

3Make sure the chain will not strike the ground or any other object during or after cutting.

4Is there a risk of kickback?

5Do the conditions and surrounding terrain affect how safely you can stand and move about?

Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension.

In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting.

IMPORTANT! If the chain jams in the cut: stop the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.

The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.

Limbing

When limbing thick branches you should use the same approach as for cutting.

Cut difficult branches piece by piece.
