Before mounting a new grinding wheel, it must be
inspected. Do not assume that a wheel is in sound
condition just because it is new—often damage
can occur in shipping, with age, or with exposure
to moisture.
First, do a Visual Inspection. Look for any
cracks, chips, nicks or dents in the surface of the
wheel. If you see any of these, DO NOT use the
wheel.
Second, do a
Ring Test. This test will give you an
indication of any internal damage that may not be
obvious during a visual inspection.
To perform ring test:
1. Make sure grinding wheel tested is clean and
dry; otherwise, you may get false results.
2. If size permits, balance grinding wheel with
your finger in mounting hole. If this is not pos-
sible, hang wheel in air with a piece of cord or
string looped through mounting hole.

such as handle of a screwdriver or a wooden
mallet.
Note: Finding exact spot to tap will take sev-
eral attempts.
When grinding, your safety depends, to a large
degree, on the condition of the wheel. A wheel in
poor condition presents the possibility of breaking
apart during rotation and injuring the operator and
others in the area.
Tips to help you avoid breaking the wheel:
• Always transport, store and handle wheels
with care. Wheels may be damaged if they
are dropped or if heavy objects are stacked
on them.
• Select right grinding wheel for job. DO NOT
grind material inappropriate for wheel type.
• Only use wheels that are rated for RPM of
tool grinder.
• Mount wheel properly (see
Installing/
Removing Grinding Wheel on Page 22).
• DO NOT push tooling into grinding wheel with
such force that it causes grinder to bog down.
And do not apply pressure to stop wheel after
turning grinder
OFF.
• Dress wheel when necessary. Do not allow it
to become glazed (see
Dressing Grinding
Wheel on Page 22).
• DO NOT store wheels in damp or wet loca-
tions.
• DO NOT overtighten nut when mounting the
wheel.
• DO NOT leave wheel mounted when machine
is not in use.
