disconnect machine from
power before adjustments,
maintenance, or service.

Schedule

For optimum performance from this machine, this
maintenance schedule must be strictly followed.
Ongoing
To minimize your risk of injury and maintain proper
machine operation, shut down the machine imme-
diately if you ever observe any of the items below,
and fix the problem before continuing operations:
• Loose mounting bolts.
• Cracked or loose grinding wheel.
• Worn or damaged wires.

Grinding Wheels

The grinding wheels should be inspected before
every use. Use the ring test method noted in
Inspecting Grinding Wheel on Page 23 to verify
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 work rest has no
more adjustment and the gap has exceeded the
safe limit.

Cleaning &
Protecting
Cleaning the Model T32251/T32252 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.
See available wheel dressers on Page 26.

Lubrication

The bearings on the Model T32251/T32252 are
