As the tree limbs 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 be-
tween the notch and back-cut.(Fig. 27)

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.
When "Cutting through", to maintain complete control of the pole saw,
release the cutting pressure near the end of the cut without relaxing
your grip on the pole 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 pole 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 button of
the saw against the log; exert light pressure downward. Note that the
saw will tend to pull away from you. (Fig. 28)
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. (Fig. 28)

LIMBING (Fig. 29)
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the 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 bind-
ing 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.
LIMBING
CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT
LIMBS UNDER TREE UNTIL LOG IS CUT
PRUNING (Fig. 30)
Pruning is trimming limbs from a live tree.
Work slowly, keep both hands on
the pole saw with a firm grip and the
handle positioned firmly against your
body for added control and ease of
handling. 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 as possible on underside of
limb stub. Use top of guide bar to make this cut. Cut 1/3 through diame-
ter of stub.
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 spring pole is 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 spring poles, they are dangerous, They could
result in severe or fatal injury.
