Maintenance & Troubleshooting - King Industrial KC-122FC-LS Manual

LUBRICATION
All of the ball bearings are packed with grease at the factory. They require no further lubrication. Periodically lubricate the splines
(Grooves) in the spindle and the rack (Teeth of the quill).
WARNING! For your own safety, turn the switch "OFF" and remove the plug from the power source before maintaining or lubricating
your drill press.
Frequently blow out any dust that may accumulate inside the motor. After operation, remove chips or dirt on the machine and apply a
coat of furniture-type paste wax to the table and the column, this will help keep the surfaces clean and free of rust.
