maintenance schedule must be strictly followed.

To maintain a low risk of injury and proper
machine operation, if you ever observe any of the
items below, shut down the machine immediately
and fix the problem before continuing operations:
•
Loose mounting bolts.
•
Cracked or loose grinding wheel.

Any other unsafe condition.
Grinding Wheels
The grinding wheels should be inspected before
every use. Use the ring test method noted in
Wheel Inspection on Page 19 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 deflector or
tool rest has no more adjustment and the gap has
exceeded the safe limit.

Cleaning &
Protecting
Cleaning the Model T28523 is relatively easy.
Vacuum excess debris, and wipe off the remaining
dust with a dry cloth.
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. 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.
Wheel Storage
Grinding wheels can be easily damaged, so it is
important to store them properly. Follow all wheel
manufacturer storage instructions. Always store
grinding wheels in a location that is dry and pro-
tected from potential damage due to them being
dropped or having other items dropped on them.
Also, avoid storing grinding wheels where there is
high humidity, extreme heat or cold, or solvents.
