WARNING. Always wear safety glasses
and keep guard in place when grinding.
Hot metal sparks from metal grinding can cause a
fire. Avoid spark contact with flammable materials
such as saw dust or clothing.
Grinding wheels must be free of fissures and
cracks. Fissures and cracks can cause a grinding
wheel to shatter resulting in possible serious injury.
Thoroughly inspect a new grinding wheel before it
is installed on the grinder.
1. Use a wooden hammer for the inspection.
2. Using the hammer, lightly tap all around the
wheel, carefully listening to the resulting
sounds.
3. Any places with fissures or cracks will result in
a different sound. Do not use a wheel
containing fissures or cracks. When installing a
new grinding wheel, a no load revolution test of
approximately one minute must be carried out
with the grinding wheel facing a safe direction,
i.e. away from people or objects.
