Operating Instructions
The MIL-4718 lock is designed for straightforward operation.
- Locking: To lock the unit, turn the handle to the closed position and use the key to engage the locking mechanism. The lock can be secured from both the inside and the outside.
- Unlocking: Insert the key into the keyhole and turn to disengage the lock. The handle can then be moved to the open position.
- Open Position Locking: The MIL-4718 can also be locked in its open position, providing additional security or preventing accidental closure depending on your specific needs.
- Key Management: It is critical to make a note of your key number for future reference, especially if replacement keys are ever needed. Keep spare keys in a secure location separate from the primary set.
Maintenance
The Milenco MIL-4718 lock requires minimal maintenance to ensure long-term performance and security.
- Cleaning: Periodically wipe the exterior of the lock with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: If the key mechanism feels stiff, apply a small amount of graphite lubricant or a silicone-based spray lubricant specifically designed for locks into the keyhole. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly inspect the mounting screws and the lock body for any signs of loosening, damage, or wear. Tighten screws as necessary.
