Basic cutting technique

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

•
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).
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.

Cutting from above = Cutting on the pull stroke.
Cutting from below = Cutting on the push stroke.
Cutting on the push stroke increases the risk of kickback.
See instructions under the heading How to avoid
kickback.
The following instructions describe how to handle the
commonest situations you are likely to encounter when
using a chain saw.
Terms
Cutting = General term for cutting through wood.
Limbing = Cutting branches off a felled tree.
Limbing
Splitting = When the object you are cutting breaks off
before the cut is complete.
When limbing thick branches you should use the same
approach as for cutting.
Cut difficult branches piece by piece.
There are five important factors you should consider
before making a cut:

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.
!

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