5. Move the grinder in the proper direction.
When using a new depressed center wheel

in direction B (Fig. 4).
Once the wheel edge is worn, the workpiece
can be ground in both directions.

speed.

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.
