7 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling English - Stabilize the log with sturdy wedges, shims or chocks, if necessary. - Never stand on a log while limbing it. ■ There is an increased danger of kickback dur‐ ing limbing operations, as limbs, leaves, stems and other material can entangle (bind) the cut‐ ters of the chain in the upper quadrant of the bar nose, causing the chain to slow or stop suddenly. - Do not use the nose of the bar to cut limbs. - Be extremely cautious and avoid contact‐ ing the log, the ground, other limbs and any leafy materials with the nose of the guide bar. ■ When underbucking freely hanging limbs, a pinch may result or the limb may fall, hitting the operator or the chain saw and causing loss of control. - If a pinch occurs that traps or holds the bar or chain, shut off the engine and acti‐ vate the chain brake before attempting to remove the saw from the cut, exercising caution that the limb does not suddenly snap or release. ■ Limbs or logs under tension (spring poles) can spring back toward you with great force, strik‐ ing you or causing you to lose control of the saw, resulting in severe or fatal injury. - Be extremely cautious when cutting limbs or logs that may be under tension. - Read and follow the warnings and instruc‐ tions on cutting logs under tension, 7.2. 7.4 Pruning Pruning is selectively removing branches from a standing tree. WARNING ■ To reduce the risk of injury from loss of con‐ trol: - Do not use the chain saw one-handed. - Never work on a ladder, on a roof, in a tree or while standing on any other inse‐ cure support. - Never operate the chain saw above shoul‐ der height or cut overhead. - Do not overreach. - If you are unable to follow these instruc‐ tions, you must use a different tool, such as a pole pruner, or have the work per‐ formed by a reputable tree service. ■ To reduce the risk of injury: - Never stand directly underneath the branch you are cutting. - Watch for falling branches. As soon as the branch starts to fall, step aside and keep a sufficient distance away from the falling wood. A branch may spring back at you after it hits the ground. - Prior to beginning work, clear the work area of limbs and brush to reduce the risk of tripping and losing control of the chain saw. To cut branches from a standing tree: When limbing: 2 1 0000-GXX-2950-A1 0000-GXX-1627-A0 ► Rest the chain saw on the log. ► Stand on the side of the log opposite the limb to be cut if it can be done safely. ► Push the guide bar at full throttle with a hinge motion against the branch. ► Cut the branch with the top or the bottom side of the guide bar, keeping the tip of the bar free of the log, the ground, other limbs and any leafy materials. ► Make the first cut (1) on the underside of the branch, approximately 2 in. (5 cm) from the trunk. Cut through approximately 1/4 of the diameter of the branch. This will help prevent the branch from splintering after it is cut. ► Make the second cut (2) on the top side of the branch, approximately 2 in. (5 cm) from the first cut. ► As soon as the branch starts to fall, withdraw the chain saw and let the branch fall to the ground. 0458-221-8621-A 21

–
Stabilize the log with sturdy wedges,
shims or chocks, if necessary.
–
Never stand on a log while limbing it.
■
There is an increased danger of kickback dur‐
ing limbing operations, as limbs, leaves, stems
and other material can entangle (bind) the cut‐
ters of the chain in the upper quadrant of the
bar nose, causing the chain to slow or stop
suddenly.
–
Do not use the nose of the bar to cut
limbs.
–
Be extremely cautious and avoid contact‐
ing the log, the ground, other limbs and
any leafy materials with the nose of the
guide bar.
■
When underbucking freely hanging limbs, a
pinch may result or the limb may fall, hitting
the operator or the chain saw and causing loss
of control.
–
If a pinch occurs that traps or holds the
bar or chain, shut off the engine and acti‐
vate the chain brake before attempting to
remove the saw from the cut, exercising
caution that the limb does not suddenly
snap or release.
■
Limbs or logs under tension (spring poles) can
spring back toward you with great force, strik‐
ing you or causing you to lose control of the
saw, resulting in severe or fatal injury.
–
Be extremely cautious when cutting limbs
or logs that may be under tension.
–
Read and follow the warnings and instruc‐
tions on cutting logs under tension,
7.2.
When limbing:
0000-GXX-2950-A1
►
Rest the chain saw on the log.
►
Stand on the side of the log opposite the limb
to be cut if it can be done safely.
►
Push the guide bar at full throttle with a hinge
motion against the branch.
►
Cut the branch with the top or the bottom side
of the guide bar, keeping the tip of the bar free
of the log, the ground, other limbs and any
leafy materials.
7.4
Pruning
Pruning is selectively removing branches from a
standing tree.
WARNING
■
To reduce the risk of injury from loss of con‐
trol:
–
Do not use the chain saw one-handed.
–
Never work on a ladder, on a roof, in a
tree or while standing on any other inse‐
cure support.
–
Never operate the chain saw above shoul‐
der height or cut overhead.
–
Do not overreach.
–
If you are unable to follow these instruc‐
tions, you must use a different tool, such
as a pole pruner, or have the work per‐
formed by a reputable tree service.
■
To reduce the risk of injury:
–
Never stand directly underneath the
branch you are cutting.
–
Watch for falling branches. As soon as the
branch starts to fall, step aside and keep
a sufficient distance away from the falling
wood. A branch may spring back at you
after it hits the ground.
–
Prior to beginning work, clear the work
area of limbs and brush to reduce the risk
of tripping and losing control of the chain
saw.

►
Make the first cut (1) on the underside of the
branch, approximately 2 in. (5 cm) from the
trunk. Cut through approximately 1/4 of the
diameter of the branch. This will help prevent
the branch from splintering after it is cut.
►
Make the second cut (2) on the top side of the
branch, approximately 2 in. (5 cm) from the
first cut.
►
As soon as the branch starts to fall, withdraw
the chain saw and let the branch fall to the
ground.
