USING GRINDING AND CUT-OFF WHEELS

Installing Grinding Wheels (Fig. 4)

1.Unplug tool and place it upside down on a level surface as shown. Remove any accessories from spindle.

2.Thread flange and nylon washer onto spindle. Attach guard and grinding wheel using Fig. 4 to determine type and order of assembly (See "Installing, Adjusting, and Removing the Guard" for attaching guard). NOTE: When installing Type 27 or Type 29 grinding wheels, position wheel 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 "Grinding". 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 in 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.

Care of Grinding & Cut-Off Wheels

WARNING!

To reduce the risk of injury, the operator should be in- structed in the use, care and protection of grinding wheels.

Grinding and cut-off wheels should be protected from:

wetness and extreme humidity

any type of solvent

extreme changes in temperature

dropping and bumping

Grinding and cut-off wheels should be stored:

in an organized way so wheels can be removed without disturbing or damaging other wheels

with their safety information

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.

Grinding and cut-off wheels should NOT be:

dropped

rolled

bumped

If any wheel is dropped, rolled, bumped, subjected to extreme changes in temperature, or has come into contact with solvents or wetness, discard wheel immediately.
