LIMBING AND PRUNING

WARNING
: Be alert for and guard
against kickback. Do not allow the moving
chain to contact any other branched or objects
at the nose of the guide bar when limbing or
pruning. Allowing such contact can result in
serious injury.
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
S Watch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch the saw chain and be
whipped toward you or pull you off balance.
S Be alert for springback.
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.
S Keep a clear work area. Frequently clear
branches out of the way to avoid tripping
over them.
LIMBING
S Always limb a tree after it is cut down. Only
then can limbing be done safely and prop-
erly.
S Leave the larger limbs underneath the
felled tree to support the tree as you work.
S Start at base of the felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
S Keep the tree between you and the chain
as much as possible.
S Remove larger, supporting branches with
the cutting techniques described in BUCK-
ING WITHOUT A SUPPORT.
S Always use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
PRUNING
WARNING
