SECTION 6: MAINTENANCE
The grinding wheel should be visually inspected
before every use. Take care in storing grinding
wheels to keep them free from potential dam-
age due to being dropped or having other items
dropped on them. Store all grinding wheels in a
dry location. Type 50 grinding wheels should be
stored vertically with cushioning material between
each wheel.
If a grinding wheel diameter has been reduced
to 5", the wheel must be replaced. Operating a
wheel at anything less than this diameter can lead
to wheel explosion and serious personal injury.
Grinding wheels will require periodic dressing.
Refer to the “Wheel Dressing” instructions on
Page 19 for details on how this is done.
