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.
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. It will do the job better
and safer at the rate for which it was
intended.
8. Remove saw from a cut with saw run-
ning at full speed. Stop saw by releas-
ing trigger. Make sure chain has
stopped before setting saw down.
9. Practice until you can maintain a steady,
even cutting rate.

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.
