Product Overview
The Master Lock 653D is a resettable 4-digit combination padlock designed for indoor use, ideal for gym and school lockers. It features a durable 2-inch (50mm) wide metal body and a 1/4-inch (6mm) diameter hardened steel shackle, providing resistance against cutting and sawing. The lock's soft-touch bottom and sides ensure a no-slip grip. This model allows users to set their own combination for enhanced security and convenience.

Setup: Setting Your Combination
Your Master Lock 653D comes with a factory preset combination, typically 0-0-0-0. Follow these steps to set your personalized 4-digit combination:
- Open the Lock: Ensure the lock is open. If it's currently locked, dial the current combination (factory default is 0-0-0-0) and pull up the shackle.
- Rotate Shackle (Step 1): With the shackle in the open position, rotate it 90 degrees counter-clockwise.
- Press and Rotate Shackle (Step 2): Press the shackle down firmly into the lock body. While holding it down, rotate it another 90 degrees counter-clockwise (total 180 degrees from the initial open position).
- Set New Combination: While the shackle is held down and rotated, set your desired 4-digit combination by turning the dials. Ensure the numbers are clearly aligned in the viewing window.
- Return Shackle: Release the shackle, then turn it back to its original open position.
- Test New Combination: Scramble the dials and then dial your new combination to ensure it opens correctly. Your new combination is now set.

Operating the Lock

- To Close: With the shackle open, insert it back into the lock body. Scramble the dials to secure the lock.
Maintenance
To ensure the longevity and smooth operation of your Master Lock 653D, consider the following maintenance tips:
- Cleaning: Wipe the lock body and shackle with a soft, damp cloth to remove dirt and grime. Avoid abrasive cleaners.
- Lubrication: Periodically apply a small amount of graphite lubricant or a silicone-based spray to the shackle mechanism and dials to maintain smooth movement.
- Storage: Store the lock in a dry environment when not in use to prevent rust, especially if used in humid conditions.
Troubleshooting
- Lock will not open: Ensure the correct 4-digit combination is entered and that each number is precisely aligned in the viewing window. If unsure of the combination, refer to the "Setup: Setting Your Combination" section for resetting instructions (if the lock is currently open).
- Shackle is stiff or difficult to move: Apply a small amount of lubricant (as described in Maintenance) to the shackle entry points and work the shackle up and down several times.
- Lock does not fit my locker: The Master Lock 653D has specific dimensions. Refer to the "Specifications" section to verify if the shackle clearance and body width are compatible with your locker's hasp. Some lockers may have narrow hasps that prevent the lock from fitting flush.
