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 between the notch and back-cut. (Fig. 17)

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 chain saw, 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
chainsaw. 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. 18)
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. 18)
OVERBUCKING
LIMBING (Fig. 19)
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the chain 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 chain saw.
Keep the tree between you and the chain 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
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.
