GRINDER OPERATION

1.Hold the grinder firmly by its handle 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 switch to the “on” position. Switch ON: Push the locking button forward

and then press the switch lever. *For continuous use, press the switch lever. The switch lever is locked by pushing the locking button forward once

again.

(*Subject to change depending on area.) Switch OFF: Press and release the switch lever.

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: 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. 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.

15°–30°

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.

6.Adjust operation to desired finish

For a fine finish, decrease pressure by lifting slightly. Grind slowly and at the appropriate speed.
