MAINTAINING YOUR DRILL PRESS
WARNING:
For your own safety, turn the switch
OFF and
remove the plug from the power source outlet before main-
taining or lubricating your drill press.
Frequently blow out any dust that accumulates inside the
motor with an air compressor or dust vacuum. A coat of
paste wax applied to the table and column will help to keep
the surface clean & help avoid rust.
To avoid shock or fire hazard, if the power cord is
worn or cut on any way, have it replaced immediately.
MAINTENANCE
LUBRICATION
All of the drill press ball bearings are packed with grease
at the factory. They require no further lubrication. Lower
spindle to maximum depth and oil moderately once every
three months.
