Grinding Wheels
The grinding wheel should be inspected before
every use. Use the ring test method noted in
Wheel Inspection on Page 20 to verify the
structural integrity. Take care in storing grinding
wheels to keep them free from potential damage
by being dropped or having other items drop on
them.
Replace the wheel when the spark arrestor or
work rest has no more adjustment and the gap
has exceeded the safe limit.
Wheel Dressing
Depending on the type of grinding you do, the
grinding wheel may require periodic dressing.
Several different kinds of wheel dressing devices
are available (see Page 22). Dressing restores the
abrasive quality of the wheel surface and squares
up the wheel edge.
Refer to the instructions that accompany your
dressing accessory for complete details on how
to properly dress a wheel.
