d. Fix the cutting object if it is unfixed.
e. Never operate the engine without wheel guard.
f. Adjust the wheel guard to deflect sparks, dust,
and material away from the operator and
flammable materials.
g. Inspect the entire unit for loose fasteners and
fuel leakage. Make sure that the blade is
properly installed and securely fastened.
h. The product is equipped with a centrifugal clutch
mechanism, so the wheel begins to rotate as
soon as the engine is started when the throttle is
in the start position. When starting the engine,
place the unit on firm ground or other solid
surface in an open area and hold it firmly in
place so as to ensure that neither the wheel
comes into contact with any obstacle when the
engine starts.
i. Never attempt to drop-start the engine.
j. Be sure the wheel does not turn while the engine
is idling. Adjust the carburetor if necessary.
■ OPERATION SAFETY PRECAUTIONS
a. Grip the handles firmly with both hands. Place
your feet slightly apart so that your weight is
distributed evenly across both legs, and always
be sure to maintain a steady, even posture while
working.
b. Keep all parts of your body away from rotating
wheel.
c. Never raise the engine speed above the
maximum spindle speed (3000 1 /
min
(rpm)).
d. If the unit start to shake or vibrate, turn off the
engine and check the whole unit. Do not use it
until the trouble has been properly corrected.
e. Keep the wheel always sharp. While using the
unit, if the wheel won’t cut well caused by
clogging, set the teeth of the saw by cutting
concrete block, clayware or sandstone.
f. Avoid standing in a direct line with the cutting
wheel.
g. Never force to push off the wheel on the cutting
object.
h. Use only downward pressure on the saw, as
lateral pressure may cause the blade to brake
and shatter.
