3. Use light grinding pressure.
There is no need to press hard when grinding. Usually the grinder’s own weight is su
ffi
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. 12
.
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. 12
), the wheel edge may cut into the workpiece. In this case, grind in
direction B (
Fig. 12
). 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 # 24 grain size. It is most
suitable for heavy grinding of steel and other types of materials.
