LIMBING AND PRUNING
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.
Slender 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
released.
S
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 1 to 2 inch collar from the trunk of the tree.

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.
After each use, ensure ON/STOP switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
S
Move ON/STOP switch to the STOP posi-
tion.
S
Loosen and remove chain brake nuts and
chain brake. Remove bar and chain from
saw.
S
Clean the oil holes and bar groove after each
5 hours of operation.
Remove Sawdust From
Guide Bar Groove
Oil Holes
S
Burring of guide bar rails is a normal
process of rail wear. Remove these burrs
with a flat file.
S
When rail top is uneven, use a flat file to re-
store square edges and sides.
