G4008/G4009 Drill Press -19-
SECTION 7: MAINTENANCE
Lubrication
Belt Tension
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.
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.
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.
