Održavanje
Proper maintenance will ensure the longevity and smooth operation of your Master Lock padlock:
- podmazivanje: Periodically (e.g., every 6-12 months, or more frequently in harsh environments), apply a small amount of graphite lubricant or a silicone-based lubricant into the keyway and around the shackle mechanism. Avoid oil-based lubricants as they can attract dirt.
- čišćenje: Wipe the padlock body with a clean, dry cloth to remove dirt and grime. For brass components, a mild brass cleaner can be used sparingly, followed by a thorough wipe.
- Briga o ključevima: Do not force the key if it feels stiff. Ensure the key is fully inserted and aligned before turning. Avoid using bent or damaged keys.
- Skladištenje: When not in use, store the padlock in a dry environment to prevent moisture buildup, especially if used outdoors.
