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 90° and repeat the test
until the entire wheel has been checked.

If cracked, there will be a dead sound
and not a clear ring.

Loosen the Knob on the Moveable Guard and
swing it open, exposing the Blade and Flange.
5. Using the included wrenches, hold the Spindle
in place with the flat Wrench and loosen
the Outer Flange with the Pin Wrench.
6. Remove the Outer Flange and Blade,
noting the orientation of each.
7. 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.

and tighten in place with the Wrenches.
9. Swing the Moveable Guard back in
place and tighten the Knob.
