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.

10 Follow 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.

•

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.

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.

1

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

2

Make sure the object you are cutting will not split.

3

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

4

Is there a risk of kickback?

5

Do 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.

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

The log is lying on the ground. There is little risk of the 
chain jamming or the object splitting. However there is a risk 
that the chain will touch the ground when you finish the cut.

Cut all the way through the log from above. Avoid letting the 
chain touch the ground as you finish the cut. Maintain full 
throttle but be prepared for what might happen.

   - If it is possible (can you turn the log?) stop cutting about 2/
3 of the way through the log.

   - Turn the log and finish the cut from the opposite side.
