OILING CHAIN
Always check oil level before using saw. To
oil chain, press squeeze bulb on oil cap. Do
not attempt to operate the oiler while cut-
ting with the saw. Oil will feed onto guide
bar and chain. Press squeeze bulb on oil cap
at least once before each cut. Check oil level
often by looking at oil sight level hole. Oil
sight level hole is on left side of saw, be-
tween front handle and front hand guard.
CUTTING WITH THE CHAIN
SAW
1.
Connect saw to extension cord. Con-
nect extension cord to power supply.
2.
Make sure section of log to be cut is
not laying on ground. This will keep
chain from touching ground as it cuts
through log. Touching ground with
moving chain will dull chain.
3.
Use both hands to grip saw. Always use
left hand to grip front handle and right
hand to grip rear handle. Use firm grip.
Thumbs and fingers must wrap around
saw handles (see Figure 9).
4.
Make sure your footing is firm. Keep
feet apart. Divide your weight evenly
on both feet. Stand slightly to left side
of saw. This keeps your body from be-
ing in direct line with chain.
5.
When ready to make a cut, press in
switch lockout with right thumb and
squeeze trigger (see Figure 9). This will
turn saw on. Releasing trigger will turn
saw off. Make sure saw is running at
full speed before starting a cut.
6.
When starting a cut, place moving
chain against wood. Hold saw firmly
in place to avoid possible bouncing or
skating (sideways movement) of saw.
7.
Guide saw using light pressure. Do not
force saw. The motor will overload and
can burn out.
8.
Remove saw from a cut with saw run-
ning at full speed. Stop saw by releas-
ing trigger. Do not use the chain brake.
Make sure chain has stopped before
setting saw down.
9.
Practice until you can maintain a steady,
even cutting rate.

Trimming a tree is the process of cutting
limbs from a living tree. Make sure your
footing is firm. Keep feet apart. Divide your
weight evenly on both feet. Follow direc-
tions below to trim a tree.
1.
Make first cut 15 centimeters (six
inches) from tree trunk on underside of
limb. Use top of guide bar to make this
cut. Cut 1/3 through diameter of limb
(see Figure 10).
2.
Move five to ten centimeters (two to
four inches) farther out on limb. Make
second cut from above limb. Continue
cut until you cut limb off.
3.
Make third cut as close to tree trunk as
possible on underside of limb stub. Use
top of guide bar to make this cut. Cut
1/3 through diameter of stub.
4.
Make fourth cut directly above third
cut. Cut down to meet third cut. This
will remove limb stub.
