3. Initial Setup
Setting Your Combination
Your padlock comes preset to a factory combination, typically 0-0-0-0. To set your personal combination:
- Ensure the padlock is open. If it's closed, use the override key to open it.
- Locate the reset mechanism. This is typically a small button or lever on the side or bottom of the padlock, or a turnable shackle. (Note: Specific reset method may vary. Refer to the packaging for exact instructions if available.)
- With the padlock open and the reset mechanism engaged (e.g., button pressed in, lever moved), set your desired 4-digit combination by rotating the dials.
- Release the reset mechanism (e.g., release button, move lever back).
- Scramble the dials to lock in your new combination.
- Important: Write down your new combination and store it in a safe, memorable place. Do not store it inside the secured area.
Using the Override Key
The override key provides backup access in case you forget your combination. Insert the key into the key slot at the bottom of the padlock and turn it to open the lock. This key can also be used to open the lock to reset the combination if you have forgotten it.
4. Operation
Opening the Padlock
- Rotate the combination dials to align with your preset 4-digit combination.
- Press the unique push-to-open button located below the dials. The shackle will release.
- Pull the shackle upwards to fully open the padlock.
Closing and Securing the Padlock
- Align the shackle with the padlock body and push it down firmly until it clicks into place.
- Scramble the combination dials to a random set of numbers. This secures the padlock and prevents unauthorized access.

5. Maintenance
To ensure the longevity and smooth operation of your Master Lock padlock, follow these maintenance guidelines:
- Cleaning: Periodically wipe down the padlock body and shackle with a clean, damp cloth to remove dirt and grime. Avoid harsh chemicals that may damage the finish.
- Lubrication: For optimal performance, especially in outdoor or dusty environments, apply a small amount of graphite lubricant or a silicone-based spray to the shackle mechanism and combination dials. Do not use oil-based lubricants as they can attract dirt.
- Inspection: Regularly inspect the padlock for any signs of wear, damage, or corrosion. Address any issues promptly.
Storage
When not in use, store the padlock in a dry environment to prevent moisture buildup, which can lead to corrosion over time.
6. Troubleshooting
| Issue | Possible Cause | Solution |
