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
saf
ely 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
tw
o 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
commonest situations y
ou 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.
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, y
ou increase the risk for
inadvertently getting a kickback, as well as increasing the
risk of losing your balance while working.
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 g
round 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 w
ay through the log.
Turn the log and finish the cut from the opposite side.
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.
