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.
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. 10.
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. 10), the wheel edge may cut into the
workpiece. In this case, grind in direction B (Fig. 10).
Once the wheel edge is worn, the workpiece can be
ground in both directions.

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.
