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
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
: 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.
S
Make your fist cut 1/3 of the way through
the 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.

Cleaning the air filter:
A dirty air filter decreases engine perform-

harmful emissions. Always clean after every
5 hours of operation.
1. Clean the cover and the area around it to
keep dirt and sawdust from falling into

BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication it may be neces-
sary to service your bar. A worn bar will dam-
age your chain and make cutting difficult.
