Installing Grinding Wheels
1. Unplug tool and place it upside down on a level surface as shown. Remove any accessories from spindle.
2. Thread nylon washer onto spindle. Attach guard and grinding wheel using Fig. 8 to determine type and order of assembly (See Fig. 2 and 3 for attach-
ing guard). NOTE: When installing Type 27 or Type 29 grinding wheels, position disc nut according to wheel thickness.
Position the guard in the location which offers best control and guard protection. For operating zones that provide maximum protection for the operator,
see Fig. 9. NOTE: When selecting Type 11 grinding cup wheels, the guard's skirt should be adjusted so that no more than 1/8" of the wheel extends
beyond the guard.
3. To tighten, press the spindle lock button while turning wheel or disc nut clockwise using the spanner wrench provided.
4. To remove grinding wheel and guard, unplug tool and reverse procedure.

Troubleshooting
Deep scratches and circular marks can result from:
• Uneven pressure
• Using a partially glazed wheel - especially on aluminum applications
• Dirt or loose metal on the workpiece
• Failure to constantly move across surface
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a small area
• Excessive pressure
• Use of worn out or glazed wheels
Inspecting Wheels
Always handle wheels carefully to avoid damage. Before installing any
wheel, always inspect it for cracks. If wheel is cracked, discard it to prevent
others from using it.
Only use wheels with Maximum Safe Operating Speed rated at
or above the RPM listed on the "WARNING" section of the tool's
nameplate. This speed is based on the strength of the wheel,
allowing for a reasonable measure of safety. It is not meant to
imply a best or most effi cient operating speed. Do not exceed the
Maximum Safe Operating Speed.
