SECTION 7: MAINTENANCE

GeneralLubrication

Make a habit of inspecting your drill press each time you use it. Check for the following conditions and repair or replace when necessary.

1.Loose mounting bolts.

2.Worn switch.

3.Worn or damaged cords and plugs.

4.Damaged V-belt.

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

Belt Tension

Proper belt tension is achieved by tightening the belt adjusting cam so the belt has a slight tension on it. Excessive tension will create heat and shorten belt life. Too little tension will cause the belt to slip and squeal.

Shielded and pre-lubricated ball bearings require no lubrication for the life of the bearings. In a con- tinuous-use environment, expect the bearings to last for several years. With intermittent use, bear- ings can be expected to last much longer. All bearings are standard sizes and can be easily replaced.

For other items on this machine, such as the quill (ref. #56 in the part breakdown), table and col- umn, an occasional shot of light machine oil is all that is necessary. Before applying lubricant, clean off sawdust and metal chips. Use a light grease on the rack, both on the teeth and between the rack and column.

The goal is to achieve adequate lubrication. Too much lubricant will attract dirt and sawdust, and clog the drill press mechanism.
