페이지 인쇄As the tree limb starts to fall, stop the saw and immediately
retreat along the cleared path. Watch the action in case
something falls your way. Be alert for overhead limbs or
branches that may fall and watch your footing.
WARNING: Never cut through to the notch when making
a back-cut. The hinge controls the fall of the tree, this is a
section of wood between the notch and back-cut.
BUCKING
Bucking is the term used for cutting a fallen tree to the desired
log length.
Always make sure your footing is secure and your weight is
distributed evenly on both feet.
Cut only one log at a time. Support small logs on a saw horse
or another log while bucking.
Keep a clear cutting area. Make sure that no objects can
contact the guide bar nose and chain during cutting, this
can cause kickback.
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.
BUCKING LOGS UNDER STRESS
When the log is supported along its entire length, it should be
cut from the top or over-bucking.
When the log is supported on one end, cut 1/3 diameter from
the underside or under-bucking. Then make the finishing cut
by over-bucking to meet the first cut.
As the log is being cut, it will tend to bend. The saw can
become pinched or hung in the log if you make the first cut
deeper than 1/3 of the diameter of the log.
Give special attention to logs under stress to prevent the bar
and chain from pinching.
OVERBUCKING – Begin on the top side of the log with
the bottom of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull away from you.
UNDER-BUCKING – Begin on the under side of the log with
the top of the saw against the log; exert light pressure upward.
During under-bucking, the saw will tend to push back at you.
Be prepared for this reaction and hold the saw firmly to
maintain control.
OPERATING
CUTTING INSTRUCTIONS
LIMBING
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on pole saw with a firm grip.
Always make sure your footing is secure and your weight is
distributed evenly on both feet.
Leave the larger support limbs under the tree to keep the tree
off the ground while cutting.
Limbs should be cut one at a time. Remove the cut limbs from
the work area often to help keep the work area clean and
safe.
Branches under tension should be cut from the bottom up to
avoid binding the pole saw.
Keep the tree between you and the pole saw while limbing.
Cut from the side of the tree opposite the branch you are
cutting.
WARNING: Never climb into a tree to limb or prune. Do not
stand on ladders, platforms, a log, or in any position which can
cause you to lose your balance or control of the saw.
PRUNING
This unit is designed for trimming
small branches and limbs up to 6"
diameter.
Pruning is trimming limbs from a live tree.
Work slowly, keeping both hands on the saw with a firm grip.
Always make sure your footing is secure and your weight is
distributed evenly on both feet.
When pruning trees it is important not to make the finishing
cut next to the main limb or trunk until you have cut off the
limb further out to reduce the weight. This prevents stripping
the bark from the main member.
Make first cut six inches from tree trunk on underside of
limb. Use top of guide bar to make this cut. (Cut 1/3 through
diameter of limb.)
Move two to four inches farther out on limb. Make second cut
from above limb. Continue cut until you cut limb off.
Make third cut as close to tree trunk as possible on underside
of limb stub. Use top of guide bar to make this cut. Cut 1/3
through diameter of stub.
Make fourth cut directly above third cut. Cut down to meet
third cut. This will remove limb stub.
SPRINGPOLES
A springpole is a branch or sapling which is bent under
tension by other wood so that it springs back if the wood
holding it is cut or removed.
WARNING: Watch out for springpoles. They are dangerous.
They could result in severe or fatal injury.
