ASSEMBLY
INSTALLING GRINDING WHEEL
See Figure 3.
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 grind- ing wheel facing a safe direction, i.e., away from people or objects.
� Unplug the grinder.
NOTE: The grinder is shipped with the disc flange and clamp nut attached to the spindle.
� 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.
Depress the spindle lock button and rotate the wheel clockwise until the spindle locks in position.
� Tighten the clamp nut securely with the wrench provided. Do not overtighten.
