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

9 for details on how this is done.
