Limbing And Pruning - Ryobi RY3714 Manuel D'utilisation

OVERBUCKING
See Figure 28.
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
See Figure 29.
Begin on the underside of the log with the top
of the saw against the log; exert light pressure
upward. During underbucking, the saw will tend
to push back at you. Be prepared for this reaction
and hold the saw firmly to maintain control.

LIMBING AND PRUNING

See Figures 30 - 31.
 Work slowly, keeping both hands on the saw
with a firm grip. Maintain secure footing and
balance.
 Keep the tree between you and the chain while
limbing.
 Do not cut from a ladder. This is extremely dan-
gerous. Leave this operation for professionals.
 Do not cut above chest height. A saw held
higher than chest height is difficult to control
against kickback.
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
balance or control of the saw and cause death
or serious personal injury.
 When pruning trees it is important not to make
the flush 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 limb or trunk.
• Underbuck the branch 1/3 through for your
first cut.
• Overbuck the branch to drop it.
• Finish by cutting smoothly and neatly against
the main limb or trunk so the bark will grow
back to seal the wound.
