Tap the at 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 90° 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.
6. For wheels with paper gaskets (blotters) or metal
gaskets: Slip the grinding wheel onto the Spindle
with the gasket rst. The gasket should be centered
on the grinding wheel and the wheel and gasket
should rest at 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.
7. Place the new GRINDING WHEEL (2)
on the SPINDLE (5) against the
REVERSIBLE INNER FLANGE (3).
8. By hand, screw the WHEEL NUT clockwise back
onto the SPINDLE, then hold in the LOCK PIN
(12) and wrench tighten only enough so that
the wheel is securely held on the spindle.
WARNING: To prevent serious injury, do not
overtighten ange. Overtightening can damage the
wheel, causing wheel failure.
