INSTALLING/REPLACING GRINDING WHEEL
See Figure 2.
WARNING:
Thoroughly inspect a new grinding wheel before
you install it on the grinder.
• Tap lightly around the wheel using a wooden
hammer.
• Listen carefully to the resulting sounds. Places
with fissures or cracks will result in a different
sound.
Do not use a wheel containing fissures or cracks.
When you install a new grinding wheel, carry out a
no load revolution test of approximately one minute
with the grinding wheel facing a safe direction, i.e.,
away from people or objects.
Unplug the grinder.
Depress the spindle lock button and rotate the clamp
nut until the spindle locks.
NOTE: To prevent damage to the spindle or spindle lock,
always allow motor to come to a complete stop before
engaging spindle lock.
Loosen and remove the clamp nut from the spindle. Do
not remove the disc flange.
Make sure the flats on the bottom of the disc flange are
engaged with the flats on the spindle.
Place the grinding wheel over the spindle.
Thread the clamp nut on the spindle with the flat side of
the nut facing up.
Fit the raised, small diameter portion of the clamp nut
into the hole in the wheel and finger tighten.
WARNING:
Always install a grinding wheel with the depressed
center against the disc flange. Failure to do so
will cause the grinding wheel to crack when
tightening the clamp nut. This could result in
serious personal injury because of loose particles
breaking off and being thrown from the grinder. Do
not overtighten.
