Lubrication points should always be __________ before adding oil to a system.

• A. Cleaned off
• B. Cleaned
• C. Inspected
• D. Repaired

Answer: (A)

Contamination control is the goal when preparing lubrication points. Before adding oil, you want to remove any dirt, old lubricant, and debris from the surface where the oil will be applied. Cleaning off the lubrication point ensures a clean surface so the new oil can enter smoothly, flow properly, and not carry in contaminants that could scratch bearings or clog passages. This helps protect seals, reduce wear, and extend component life. Simply stating that a area is cleaned is less precise about removing all residues; and inspection or repair are separate steps that don’t guarantee a clean lubrication surface.
