SECTION 6: MAINTENANCE
Always disconnect power
to the machine before
performing maintenance.
Failure to do this may
result in serious person-
al injury.
For optimum performance from your machine,
follow this maintenance schedule and refer to
any specific instructions given in this section.
Routinely check the condition of the following
items and repair or replace as necessary:
• Cracked or loose grinding wheel.
• Loose mounting bolts.
• Worn switch.
• Worn or damaged cords and plugs.
• Any other condition that could hamper the
safe operation of this machine.
Schedule
The grinding wheel 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 wheel diameter
is reduced to 2" smaller than its original size.
Operating at anything less than this diameter
does not allow the proper surface speed for grind-
ing or spacing of the tool rest and the eye shield,
and the grinding wheel may fly apart.
