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 chain saw. Always
stop the motor before moving from tree to tree.
TYPES OF CUTTING USED
See Figure 20.
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.
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 bal-
ance or control of the saw and cause death or
serious personal injury.
LIMBING
See Figure 21.
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.
