Basic cutting technique
WARNING! Never use a chainsaw by
!
holding it with one hand. A chainsaw is
not safely controlled with one hand.
Always have a secure, rm 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 ve important factors you should consider
before making a cut:
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.

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 rst 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 chainsaw free. If you do you
may be injured by the chain when the chainsaw
suddenly breaks free. Use a lever to open up the cut and
free the chainsaw.
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 difcult branches piece by piece.

Cutting
WARNING! Never attempt to cut logs
!
while they are in a pile or when a couple
of logs are lying together. Such
procedures drastically increase the risk
of kickback which can result in a serious
or fatal injury.
If you have a pile of logs, each log you attempt to cut
should be removed from the pile, placed on a saw horse
or runners and cut individually.
Remove the cut pieces from the cutting area. By leaving
them in the cutting area, you increase the risk for
