H7762 Heavy Duty Tool Grinder
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 1
