BUCKING WITH A WEDGE
If the wood diameter is large enough for
you to insert a soft bucking wedge without
touching the chain, you should use the wedge
to hold the cut open to prevent pinching.
BUCKING LOGS UNDER STRESS
When the log is supported on one end, cut
1/3 the diameter from the underside. Then
make the finished cut by overbucking to meet
the first cut. When the log is supported on
both ends, cut 1/3 of the diameter from the
top. Then make the finished cut by under
bucking the lower 2/3 to meet the first cut.

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 under bucking, the saw will
tend to push back at you. Be prepared for this
reaction and hold the saw firmly to maintain
control.
LIMBING
Limbing is removing branches from a fallen
tree.
• Work slowly, keeping both hands on the
chainsaw 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.
• Branches under tension should be cut
from the bottom up to avoid binding the
chainsaw.
• Keep the tree between you and the
chainsaw while limbing. Cut from the side
of the tree opposite the branch you are
cutting.
