Maintenance
The Prime-Line U 9947 lock is designed for durability and corrosion resistance. To ensure optimal performance and longevity:
- Cleaning: Periodically wipe the exterior of the lock with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners that may damage the brass plated finish.
- Lubrication: If the key mechanism becomes stiff, apply a small amount of graphite lubricant or a silicone-based spray lubricant into the keyway. Do not use oil-based lubricants as they can attract dust.
- Inspection: Regularly check the mounting screws for tightness and the overall condition of the lock for any signs of wear or damage.
Troubleshooting
