NOTE
Use caution not to turn the dial scale to any value below
1 or above 6.
CAUTION
● When using the grinder in the immediate vicinity
of welding equipment, the rotational speed may
become unstable. Do not use the grinder near
welding equipment.

● When using the tool at any value except the
full speed (Dial scale 6), the motor cannot be
suffi ciently cooled due to the decreased number of
revolution. This could result in the risk of burning
and damaging the motor before an overload
protective mechanism starts to function. Make
sure that you use the tool by lightly applying it
to the surface of material when you use it at any
value except the full speed (Dial scale 6).
WARNING
Do not press the grinder forcibly against the
surface to be ground. Heavy pressure can result
in wheel breakage and serious injury. It can also
damage the surface being ground or damage the
grinder's motor.
3. Precautions on operation
(1) Lightly press the wheel to the material to be ground
when grinding materials, high-speed revolution is
necessary. Use a hand grinder with high-speed
revolution, minimizing the pressing force.
(2) Dressing the wheel
After attaching a wheel, adjust defl ection of the wheel
center by using a dresser.
If the wheel center is eccentric, not only precise
fi nishing cannot be achieved but also grinder vibration
increases, lowering grinder accuracy and durability.
A clogged or worn wheel will soil the fi nishing surface or
lower grinding effi ciency. Occasionally dress the wheel
by applying the dresser.
