•Worn or damaged cord.

•Worn or damaged support bearings.

Lubrication

Sealed and pre-lubricated ball bearings require no lubrication for the life of the bearings. All bear- ings are standard sizes, and replacements can be purchased from our Parts Department or a bear- ing supply store.

Grinding Wheels

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.
