• Loose mounting bolts.
• Worn switch.
• Worn or damaged cords and plugs.

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.
