SAFETY INSTRUCTIONS
The following instructions describe how to handle the
common situations you are likely to encounter when using a
chain saw.
Cutting
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
fi
nish the cut.
Cut all the way through the log from above. Avoid letting the
chain touch the ground as you
fi
nish 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
fi
nish the cut from the opposite side.
The log is supported at one end.
There is a high risk that it
will split.
Start by cutting from below (about 1/3 of the way through).
Finish by cutting from above so that the two cuts meet.
The log is supported at both ends.
There is a high risk that
the chain will jam.
Start by cutting from above (about 1/3 of the way through).
Finish by cutting from below so that the two cuts meet.
Limbing
When limbing thick branches you should use the same
approach as for cutting.
Cut dif
fi
cult branches piece by piece.
Tree felling technique
Safe distance
The safe distance between a tree that is to be felled and
anyone else working nearby is at least 2 1/2 tree lengths.
Make sure that no-one else is in this ”risk zone” before or
during felling.
Felling direction
The aim is to fell the tree in a position where you can limb and
cross-cut the log as easily as possible. You want it to fall in a
location where you can stand and move about safely. The
main point to avoid is letting the tree fall onto another tree.
See instructions under the heading Freeing a tree that has
fallen badly.
!
WARNING! It takes a lot of experience to fell
a tree. Inexperienced users of chain saws
should not fell trees. Do not attempt any task
that you feel unsure of!
