Installing a Non-threaded Grinding (cut-off) Wheel
1. The Grinding (cut-off) Wheel MUST be:
• rated to at least 7000 RPM.
• no larger than 4-1/2" (115 mm) in diameter.
• fitted with a 7/8" round arbor hole.
• 4-1/2" (115 mm) thick or less.
• suitable for surface edge grinding,
not edge surface grinding.
• dry and clean.
• proven undamaged by inspection and
by the ring-test explained below.
2. Press in and hold the Spindle Lock Button
to prevent the Spindle from turning.
3. Using included Wrench, remove the Outer Flange.
Keep the Inner Flange in position on the Spindle.
4. 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.

For technical questions, please call 1-888-866-5797.
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.
5. 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.
6. Thread the Outer Flange onto the Spindle.
Wrench tighten only enough so that the wheel is
securely held on the spindle.
WARNING: To prevent serious injury,
do not overtighten flange. Overtightening can
damage the wheel, causing wheel failure.
