Maintenance
This lock is designed for easy maintenance and long-term durability, featuring stainless steel components.
General Care:
- Cleaning: Wipe the stainless steel front and visible parts with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: Periodically apply a small amount of graphite-based lubricant to the keyway and internal moving parts of the cylinder to ensure smooth operation. Do not use oil-based lubricants as they can attract dust and debris.
- Inspection: Regularly check all mounting screws for tightness. Ensure the lock operates smoothly without excessive force.
The rust-proof nature of the stainless steel material contributes to the lock's longevity and reduces the need for extensive rust prevention measures.
