e. Limbing
Limbing is removing branches from a fallen
tree. When limbing, leave larger limbs to
support the log off the ground. Remove the
small limbs in one cut as illustrated in Fig. Q .
Branches under tension should be cut from
the bottom up to avoid binding the chain
saw.
WARNING: There is an extreme danger of
kickback during the limbing operation. Be
extremely cautious and avoid contacting the
log or other limbs with the tip of the guide bar.
f. Bucking a log (See Fig. R)
Bucking is cutting a log into lengths. It is
important to make sure your footing is firm
and your weight is evenly distributed on
both feet. When possible, the log should be
raised and supported by the use of limbs,
logs or chocks. Follow the simple directions
for easy cutting.
WARNING: Keep a clear cutting area. Make
sure that no objects can contact the guide
bar nose and chain during cutting; this can
cause kickback.
Overbucking
Begin on the top side of the log with the
bottom of the saw against the log; exert
light pressure downward. Note that the saw
will tend to pull away from you.
Underbucking
Begin on the underside of the log with the
top of the saw against the log; exert light
pressure upward. During underbucking,
the saw will tend to push back at you. Be
prepared for this reaction and hold the saw
firmly to maintain control.
• When the log is supported along its
entire length, it should be cut from the
top (overbucking) (See Fig. S ).
• When the log is supported on only one
end, cut 1/3 the diameter from the
underside (underbucking). Then make
the finishing cut by overbucking to meet
the first cut (See Fig. T ).
• When the log is supported on both ends,
cut 1/3 of that diameter from the top
overbuck. Then make the finished cut by
underbucking the lower 2/3 to meet the
first cut (See Fig. U ).
• When bucking on a slope, always stand
on the uphill side of the log (See Fig. V ).
• To maintain complete control when
cutting through, release the cutting
pressure near the end of the cut without
relaxing the grip on the chain saw
handles. Don’t allow the chain to contact
the ground. After completing the cut,
wait for the saw chain to stop before you
move the chain saw. Always stop the
motor before moving from tree to tree.
18. Maintenance
WARNING: When servicing, use only
identical replacement parts. Use of any
other parts may create a hazard or cause
product damage. To ensure safety and
reliability, all repairs should be performed by
a qualified service technician.
WARNING: Always wear safety goggles
or safety glasses with side shields during
power tool operation or when blowing dust.
If the operation is dusty, also wear a dust
mask.
WARNING: To avoid serious personal injury,
remove the battery pack from the chain saw
before inspecting, cleaning, or performing
maintenance. A battery operated tool with
the battery pack inserted is always on and
can start accidently.
WARNING: When cleaning the chain saw,
DO NOT immerse in water or other liquids.
WARNING: Do not at any time let brake
fluids, gasoline, petroleum-based products,
penetrating oils, etc., come in contact with
plastic parts. Chemicals can damage,
weaken, or destroy plastic, which may result
in serious personal injury.
18.1
Cleaning
• After each use, clean debris from the
chain and guide bar with a soft brush.
Wipe the chain saw surface with a
clean cloth moistened with a mild soap
solution.
• Remove the side cover, and then use a
soft brush to remove debris from the
guide bar, saw chain, sprocket and side
cover.
