S Give special attention to logs under strain to
prevent the saw from pinching. Make the first

on the log.

Be alert for and guard
WARNING:
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. 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 re-
leased.
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 proper-
ly.
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:
shoulder height or below.
branches are higher than your shoulder. Get a
professional to do the job.
S Make your fist cut
1/3
bottom of the limb.
S Next make a 2nd cut all the way through the
limb. Then cut a third overcut leaving a 3 to 5
cm collar from the trunk of the tree.
