MAINTENANCE
WARNING! For your own safety, turn the switch "OFF" and remove the
plug from the power source before maintaining or lubricating your drill
press.
• Keep the Drill Press clean and free of dust and debris. Painted surfaces
can be wiped with a damp rag.
• Periodically lubricate all sliding or moving parts including the column and
rack (A & C) Fig.8 and the quill (C) Fig.16 (use any all purpose grease,
available at any hardware store).
• Lightly grease the belt tension slide bars (A) Fig.23 every two months or
as needed depending on frequency of use.
• Bearings in the quill and the V-belt pulleys are sealed and permanently
lubricated – no further lubrication is required.
• 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.
