Pillow Block Bearings
Bearings should be lubricated every month of operation. Do not over lubricate. One or two
pumps from a hand operated grease gun is sufficient.
Belts
Do not use belt dressing. Belt dressing will collect material and cause the belts to slip and /or
wear faster. There is no substitute for keeping belts dry, free of oil and grease, and tight. Replace
worn and deteriorated belts as required.
