4. Onderhoud
Regular maintenance ensures the longevity and reliable operation of your Master Lock padlock.
- Schoonmaak: Veeg het hangslot en de beugel regelmatig af met een schone, droge doek om vuil en stof te verwijderen.
- Smering: For optimal performance, especially in cold or harsh environments, apply a small amount of graphite lubricant or a silicone-based spray lubricant into the keyway and around the shackle mechanism once or twice a year. Avoid oil-based lubricants as they can attract dirt.
- Roestbescherming: The padlock features proprietary rustproofing. However, for prolonged exposure to extreme moisture or corrosive conditions, additional protective measures may be considered.
5. Probleemoplossing
| Probleem | Mogelijke oorzaak | Oplossing |
|---|---|---|
| Sleutel is moeilijk in te brengen of te draaien. | Dirt or debris in the keyway; lack of lubrication; worn key. | Clean the keyway with compressed air. Apply graphite or silicone lubricant. Try a spare key if available. |
