Pruning - Stihl MSA 120 C Manual De Instrucciones

English
WARNING
￭ To prevent a log from rolling while limbing:
– Start limbing by leaving the limbs on the lower,
downhill side of the log to hold the log off the ground.
– 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 during limbing
operations, as limbs, leaves, stems and other material can
entangle (bind) the cutters 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 contacting 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,
switch off the motor, activate the chain brake and
remove the battery from the saw 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, striking 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 instructions on
cutting logs under tension, @ 8.5.

8 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
When limbing:
► 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.

Pruning

Pruning is selectively removing branches from a standing
tree.
WARNING
￭ To reduce the risk of injury from loss of control:
– 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 insecure support.
– Never operate the chain saw above shoulder height
or cut overhead.
– Do not overreach.
