5. Closely inspect the new cut-off wheel before mounting.
Perform a ring-test on the wheel as follows:
a. Suspend wheel using a dowel or
finger through the arbor hole.
b. 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. Refer to Figure C.

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 cut-off wheel onto the Spindle with
the gasket first. The gasket should be centered on
the wheel and the wheel and gasket should rest
flat against the Inner Flange.
WARNING: To prevent serious injury, gaskets
must be used for all cut-off wheels they are
provided with. Gaskets help prevent cut-off
wheel damage and wheel slippage, causes of
wheel failure.
7. Install the new cut-off wheel, and reassemble the
parts shown in Figure B. The concave side of the
Outer Flange must face the Wheel.
8. Hold in the Spindle Lock and wrench tighten
the Arbor Bolt by turning it clockwise. Release
the Spindle Lock.
WARNING: To prevent serious injury, do not
overtighten flange. Overtightening can damage
the wheel, causing wheel failure.
