6. Adjusting the number of revolution
These models are equipped with an electronic infi nite-
variable-speed drive and can change the number of
revolution according to a use.
If you turn and set the dial scale (Fig. 6) to 6, the number
of revolution increases, and if you turn and set it to 1, the
number of revolution decreases.
Before use, set the number of revolution using the dial.
In so doing, refer to the following table as a rough guide.
Dial Use
1 Polishing, fi nishing
2 Removal of paint or coat
3 Removal of rust
4 Removal of burrs
5 Grinding
6 Rough grinding
NOTE: Use caution not to turn the dial scale to any value
below 1 or above 6.
7. Caution when using near welding equipment
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.
8. Using the side handle (Fig. 3)
Be sure to use the side handle to avoid the risk of severe
electrical shock.
Attach the side handle to the machine as follows.
(1) Loosen the side handle grip and insert the side handle
to the nose bracket part of the machine from the fl ange
part of the side handle sleeve.
(2) Set the side handle to a position that is suited to the
operation and then securely tighten the side handle
grip.
HOW TO USE
1. Switching operation
(1) When moving the switch lever to the right (ON side),
power is applied; when moving it to the left (OFF side),
power is switched off .
(2) When fi rst turning on the switch after installing a new
wheel, hold the grinder away from your body to avoid
any danger of a wheel shattering due to an imperfection.
(3) Before starting, test the machine with the wheel pointed
in a safe direction.

2. Precautions on operation
(1) Lightly press the wheel to the material to be ground.
When grinding
is necessary. Use a hand grinder with high-speed
revolution, minimizing the pressing force.
CAUTION
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).
(2) Dressing the wheel
After attaching a wheel, correct 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 spoil the fi nishing surface
or lower grinding effi ciency. Occasionally dress the
wheel by applying the dresser.
WHEEL SELECTING METHOD
Types of wheels are varied according to the materials to
be ground. Select a wheel appropriate for the material to
be ground.
