The Wheel Dresser is to be used on the grinding
wheels. It will remove buildup of material on the grind-
ing wheel, remove imperfections and make the corners
of the grinding wheel square. See Fig. J.
1. Loosen the correct side tool rest (A) and adjust it
until it is in the flat horizontal position as shown and
1/16" away from the grinding wheel.
2. Turn "ON" the Bench Grinder. Let the grinding
wheel come up to a steady speed for one minute.
.
After the grinding wheel has gotten to a steady
speed, place the Wheel Dresser (B) flat on the Tool
Rest with the serrated wheels facing the grinding
wheel.
4. Firmly hold on to the handle of the Wheel Dresser.
.
Move the Wheel Dresser forward until the serrated
wheels make light contact with the grinding wheel
(C). After contact has been made, slide the Wheel
Dresser side to side across the Tool Rest to dress
the grinding wheel until the edge of the grinding
wheel is square and the surface is clean.
6. After the operator has completed dressing the
grinding wheel, turn "OFF" the Bench Grinder and
let the grinding wheel come to a complete stop.
7. Inspect the grinding wheel for any damage!
.
The grinding wheel may now be slightly smaller in
diameter after dressing. Readjust the tool rests and
spark arrestors to maintain a 1/16" clearance to the
grinding wheel.
