•
keep a clear-cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this
can cause kickback. Refer to kickback earlier in this manual.
•
When bucking on a slope, always stand on the uphill side of the log. To maintain complete control of the chain saw
when cutting through the log, release the cutting pressure near the end of the cut without relaxing your grip on the
chain saw handles. Do not let the chain contact the ground. After completing the cut, wait for the saw chain to stop
before you move the chain saw. Always stop the motor before moving from tree to tree.
CUTTING TREES AND BRANCHES THAT ARE IN TENSION
Preparations:
Work out which side is in tension and
where the point of maximum tension is (i.e. where it would
break if it was bent even more). Decide which is the safest
way to release the tension and whether you are able to do
it safely. In complicated situations the only safe method is
to put aside your chain saw and use a winch.
general advice
Position yourself so that you will be clear of the tree or
branch when the tension is released. See fig 22.
•
Make one or more cuts at or near the point of maximum
tension. Make as many cuts of sufficient depth as
necessary to reduce the tension and make the tree or
branch break at the point of maximum tension. See fig
23.
CAUTION: Never cut straight through a tree
or branch that is in tension!
•
If you must cut across tree/limb, make two to three cuts,
one inch apart, one to two inches deep. See fig 24.
•
Continue to cut deeper until tree/limb bends and tension
is released.
•
Cut tree/limb from outside the bend, after tension has
been released. See fig 25.
LIMBING (FIG 26)
Warning:
accidents occur during limbing. Do not use
the kickback zone of the guide bar.
Be extremely cautious and avoid contacting the log, other
limbs or objects with the nose of the guide bar. Be extremely
cautious of limbs under tension. They can spring back
toward you and cause loss of control resulting in injury.
When limbing, leave larger, lower limbs to support the tree
off the ground. Limbs should be cut one at a time. Branches
under tension should be cut from the bottom up to avoid
binding the chain saw.
Make sure that you can stand and move about safely. Work on the left side of the trunk. Work as close as possible to the
chain saw for maximum control. If possible, let the weight of the chain saw rest on the trunk.
keep the trunk between you and the chain saw as you move along the trunk.
