TYPES OF CUTTING USED
See Figure 21.
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.
UNDERBUCKING
Begin on the under side of the log with the top of the
saw against the log; exert light pressure upward.
During underbucking, the saw will tend to push back at
you. Be prepared for this reaction and hold the saw
firmly to maintain control.

OPERATION
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
See Figure 22.
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.
