O ERBUCKING
LIMBING
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.
PRUNING
Pruning is trimming limbs from a live 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.
• Do not cut from a ladder, this is extremely
dangerous. Leave this operation for
professionals.
• Do not cut above chest height as a saw held
higher is difficult to control against kickback.
• 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.
• Underbuck the branch 1/3 through for your
first cut.
• Your second cut should overbuck to drop
the branch off.
• Now make your finishing cut smoothly and
neatly against the main member so the bark
will grow back to seal the wound.

CUTTING SPRINGPOLES
A springpole is any log, branch, rooted stump,
or sapling which is bent under tension by
other wood so that it springs back if the wood
holding it is cut or removed. On a fallen tree, a
rooted stump has a high potential of springing
back to the upright position during the bucking
cut to separate the log from the stump. Watch
out for springpoles — they are dangerous.
WARNING:
Springpoles are dangerous and could strike
the operator, causing the operator to lose
control of the chain saw. This could result in
severe or fatal injury to the operator.
