Replacing a Grinding Wheel
1. The Grinding Wheel MUST be:
• rated to at least 3,450 RPM.
• no larger than 6″ (152.4 mm) in diameter.
• fitted with a 1/2″ round arbor hole.
• 3/4″ thick.
• suitable for edge grinding, not surface grinding.
• dry and clean.
• proven undamaged by inspection and
by the ring-test explained below.
2. Loosen each Eye Shield Lock Nut and move
both Eye Shields up to access the Work Rests.
3. Remove both Work Rests.
4. Remove the Screws (21) holding Wheel
Covers (20, 33) to the Bench Grinder.
5. Remove Wheel Covers.
6. Place a small wooden wedge between
the Grinding Wheel and Work Rest
to prevent Wheel from rotating.
7. Remove the right side Grinding Wheel (34)
by turning the Nut (32) counterclockwise
with a wrench (not included).
8. Remove the left side Grinding Wheel (18) by turning
the Nut (19) clockwise with a wrench (not included).
9. Remove the Outer Flange (17) and
remove Grinding Wheel. Keep the
Inner Flange in position on the Spindle.
10. Closely inspect the wheel before mounting.
Perform a ring-test on the wheel (unless wheel is
smaller than 4″ or is an unusual shape) as follows:
a. Suspend wheel using a dowel or
finger through the arbor hole.

Tap the flat side of the wheel with a light
non-metallic object, such as a screwdriver
handle, at a point 45° from the vertical center
line on each side of the wheel and 1 – 2 inches
from the edge of the wheel (see Illustration).
c. Rotate the wheel and repeat the test until
the entire wheel has been checked.
d. An undamaged wheel will
give a clear tone. If cracked, there will be
a dead sound and not a clear ring.
11. For wheels with paper gaskets (blotters) or
metal gaskets: Slip the grinding wheel onto the
Spindle with the gasket first. The gasket should be
centered on the grinding wheel and the wheel and
gasket should rest flat against the Inner Flange.
WARNING: To prevent serious injury, gaskets
must be used for all grinding wheels they are
provided with. Gaskets help prevent grinding
wheel damage and wheel slippage,
causes of wheel failure.
