3. Use light grinding pressure.
There is no need to press hard when grinding. Usually
the grinder's own weight is suffi cient to allow the
required light contact with the surface to be ground.
Do not apply the grinding wheel strongly to the grinding
surface. The grinder makes use of electronic circuit,
so during application of load rotates at high speed,
so ample grinding eff ect can be obtained by applying
light pressure. If a strong grinding pressure or other
abnormal load is applied, the overload protection
circuit will operate and make the grinder stop rotating,
so please stop applying load immediately. Following
this, switching the power OFF and then ON again, will
cause the rotation to increase to the regular speed.
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.
4. Use proper grinding angle.
Grind only with the wheel's edge by lifting the grinder
15° to 30°, as shown in Fig. 17.
CAUTION
Do not use the entire surface of the depressed
center wheel. Use only the edge of the depressed
center wheel.

5. Move the grinder in the proper direction.
When using a new depressed center wheel in direction
A (Fig. 17), the wheel edge may cut into the workpiece.
In this case, grind in direction B (Fig. 17).
Once the wheel edge is worn, the workpiece can be
ground in both directions.

NOTE
The wheel provided (resinoid wheel) is rated as Class
A grain and # 36 grain size. It is most suitable for
heavy grinding of steel and other types of materials.
6. Adjust operation to desired fi nish.
For a fi ne fi nish, decrease pressure by lifting slightly.
Grind slowly and at the appropriate speed.
CAUTION
The revolving depressed center wheel will create
air turbulence.
Do no lay the grinder down in areas of dust or dirt
until it has come to a complete stop.
