Grinder Operation - Hitachi G 10SR2 Mode D'emploi

GRINDER OPERATION

1. Hold the grinder firmly by its housing and
side handle (Fig. 1).
The grinder produces a counterforce which
must be controlled by firmly holding onto the
grinder.
2. Turn the grinder "on". (Fig. 3)
While holding the grinder firmly, use one finger
to slide the switch to the "on" position.
3. Use light grinding pressure.
There is no need to press hard when grinding.
Usually the grinder's own weight is sufficient
to allow the required light contact with the
surface to be ground.
WARNING:
4. Use proper grinding angle.
Grind only with the wheel's edge by lifting the grinder 15° to 30°, as shown in Fig. 4.
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. 4), the wheel edge may cut into
the workpiece. In this case, grind in direction B
(Fig. 4).
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 finish.
For a fine finish, 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.
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.
