LIMBING AND PRUNING
_WARNING:
Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branches or ob-
jects at the nose of the guide bar when limb-
log or pruning. Allowing such contact can re-
sult in serious injury.
_k WARNING:
Never climb into a tree to
limb or prune. Do not stand on ladders, plat-
forms, a log, or in any position which can cause
you to lose your balance or control of the saw.
IMPORTANT POINTS
• Work slowly, keeping both hands firmly
gripped on saw. Maintain secure footing
and balance.
• Watch out for springpoles, Use extreme
caution when cL_ting small size limbs. Slen-
der material may catch saw chain and be
whipped toward you or pull you off balance.
• Be alert for springback, Watch out for
branches that are bent or under pressure,
Avoid being struck by the branch or the
saw when the tension in the wood fibers is
released.
• Keep a clear work area, Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
• Always limb a tree after it is cut down. Only
then can limbing be done safely and prop-
erly.
• Leave the larger limbs underneath the
felled tree to support the tree as you work,
• Start at base of the felled tree and work to-
ward the top, cutting branches and limbs,
Remove small limbs with one cut.
• Keep the tree between you and the chain
as much as possible. Cut from the side of
the tree opposite the branch your are cut-
ting.
• Remove larger, supporting branches with
the cutting techniques described in BUCK-
ING WITHOUT A SUPPOR£
• Always use an overout to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw,
PRUNING

Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder, Get
a professional to do the job.
• Make your fist cut I/3 of the way through
the bottom of the limb.
• Next make a 2nd cut all the way through
the limb. Then cut a third overcut leaving a
1 to 2 inch collar from the trunk of the tree,
