LIMBING
See Figure 29.
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, which could result
in death or other serious personal injury.
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 op-
posite the branch you are cutting.
PRUNING
See Figure 30.
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 dan-
gerous. 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.
OPERATION
CUT LIMBS ONE AT A TIME AND LEAVE SUPPORT
LIMBS UNDER TREE UNTIL LOG IS CUT
FIRST CUT
1/3 DIAMETER
FINISHING CUT
 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.
WARNING:
If the limbs to be pruned are above chest height,
hire a professional to perform the pruning.
Failure to do so could result in death or serious
personal injury.
