SECTION 6: MAINTENANCE

Disconnect power to the
machine when perform-
ing	any maintenance,
assembly		or	adjust-
ments. Failure to do this
may	result	in	serious
personal injury.
General
Always be aware of the condition of your machine.
Routinely check the condition of the following
items and repair or replace as necessary:

•Damaged or loose grinding wheel

•Loose mounting bolts

•Worn switch

•Worn or damaged cord

•Worn or damaged support bearings

•Any other condition that could hamper the safe operation of this machine.

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 inspected before every use. Use the “ring test” method on Page 17 to verify the structural integrity. Take care in storing grinding wheels to keep them free from potential damage due to being dropped or having other items dropped on them.

Replace the wheel when the wheel diameter is reduced to 5". Operating at anything less than this diameter does not allow the proper alignment of the tool rest and the eye shield.

Depending on the type of grinding you do, the grinding wheel may require periodic dressing. Refer to the “Wheel Dressing” instructions on Page 18 for details on how this is done.

Sanding Belts

Sanding belts can be cleaned ("unloaded") with commercially-available crepe-rubber belt clean- ers. To clean, simply press the belt cleaner up against the moving belt and move across the surface of the belt until all wood dust has been removed. Grizzly's line of professional-grade PRO-STIK®belt cleaners can be found on Page 21.
