SAFETY INSTRUCTIONS

General
Basic cutting technique
Two factors decide whether the chain will jam or the log will
split. The first is how the log is supported and the second is
whether it is in tension.
•
Always use full throttle when cutting!
In most cases you can avoid these problems by cutting in two
stages; from the top and from the bottom of the log. You need
to support the log so that it will not trap the chain or split during
cutting.
•
Reduce the speed to idle after every cut (running the
engine for too long at full throttle without any load can lead to
serious engine damage).
•
•
Cutting from above = Cutting on the pull stroke.
Cutting from below = Cutting on the push stroke.
!
If the chain jams in the cut:
STOP THE ENGINE! Don’t try to pull the saw
free. If you do you may damage the chain
when the saw suddenly breaks free. Use a
lever to open up the cut and free the bar.
See the section on ”How to avoid kickback” to find out why
cutting on the push stroke increases the risk of kickback.

The following instructions describe how to handle most types of
situation that you will be faced with when using a chain saw.
Cutting
1
The log is lying on the
ground. There is little risk
of the chain jamming or
the log splitting. However
there is a risk that the
chain will touch the
ground when you finish
the cut.
There are five important factors you should consider
before making a cut:

3
Make sure the bar will not
jam in the cut.
Cut all the way through
the log from above. Try
not to touch the ground as
you finish the cut.
Maintain full throttle but
be prepared in case the
chain snatches.
Make sure the log will not
split.
A If it is possible to turn
the log you should stop
cutting about 2/3 of the
way through.
Make sure the chain will
not strike the ground or
any other object during or
after cutting.
B Turn the log and finish
the cut from the
opposite side.
