6 - GENERAL CUTTING INSTRUCTIONS
6-2. LIMBING
Limbing a tree is the process of removing the branches
from a fallen tree. Do not remove supporting limbs (A) until
after the log is b
ucked (cut) into lengths (Figure 6-2A).
Branches under tension should be cut from the bottom up
to a
void binding the chain saw.
WARNING
Never cut tree limbs while standing on tree trunk.
6-3. BUCKING
Bucking is cutting a fallen log into lengths. Make sure you
have a good footing and stand uphill of the log when cutting
on sloping ground. If possible, the log should be supported
so that the end to be cut off is not resting on the ground. If
the log is supported at both ends and you must cut in the
middle, make a downward cut halfway through the log and
then make the undercut. This will prevent the log from
pinching the bar and chain. Be careful that the chain does
not cut into the ground when bucking as this causes rapid
dulling of the chain.
When bucking on a slope, always stand on the uphill side.
1. Log supported along entire length: Cut from top (over-
b
uck), being careful to avoid cutting into the ground
(Figure 6-3A).
2. Log supported on 1 end: First, cut from bottom (under-
buck) 1/3 diameter of log to avoid splintering. Second,
cut from above (overbuck) to meet first cut and avoid
pinching (Figure 6-3B).
3. Log supported on both ends: First, overbuck 1/3 diam-
eter of log to a
void splintering. Second, underbuck to
meet first cut and a
v
oid pinching (Figure 6-3C).
NO
TE:
The best w
a
y to hold a log while b
uc
king is to use a
sawhorse. When this is not possible, the log should be
r
aised and suppor
ted b
y the limb stumps or b
y using sup-
por
ting logs
.
Be sure the log being cut is securely suppor

ed.
6-4.BUCKING USING A SAWHORSE
For personal safety and ease of cutting, the correct position
for vertical bucking is essential (Figure 6-4A).
VERTICAL CUTTING:
A. Hold the saw firmly with both hands and keep the saw
to the right of your body while cutting.
B. Keep the left arm as straight as possible.
C. Keep weight on both feet.
CAUTION
While the saw is cutting, be sure the chain and bar are
being properly lubricated.

7 - MAINTENANCE INSTRUCTIONS
All chain saw service, other than items listed here in your user manual maintenance
instr
uctions, should be performed by your nearest Authorized Service Center.
7-1.PREVENTIVE MAINTENANCE
A good pre
ventive maintenance program of regular inspection and care will increase life and improve performance of your MTD
chain saw. This maintenance checklist is a guide for such a program.
Cleaning, adjustment, and parts replacement may be required, under certain conditions, at more frequent intervals than those
indicated.
