- First Number: Turn the dial clockwise to the first number of your preset combination. Stop precisely on this number.
- Second Number: Turn the dial counter-clockwise past zero once, then continue to the second number of your combination. Stop precisely on this number.
- Third Number: Turn the dial clockwise directly to the third number of your combination. Stop precisely on this number.
- Open: Pull up on the shackle to open the padlock.

Note: The combination for your padlock is permanently set at the factory and cannot be changed. It is typically found on a sticker on the back of the packaging or on the lock itself when new. Keep this combination in a safe, memorable place.
Maintenance
To ensure the longevity and smooth operation of your Master Lock 1500T combination padlock, consider the following maintenance tips:
- Keep Clean: Periodically wipe the lock body and shackle with a soft, dry cloth to remove dust and grime.
- Avoid Moisture: As this padlock is designed for indoor use, protect it from excessive moisture and humidity to prevent rust or corrosion.
- Lubrication (Optional): If the dial or shackle mechanism becomes stiff over time, a small amount of graphite lubricant or a silicone-based spray lubricant can be applied to the moving parts. Avoid oil-based lubricants as they can attract dirt.
Troubleshooting
Lock Does Not Open:
- Verify Combination: Double-check that you are using the correct preset 3-digit combination. The combination is fixed and cannot be changed.
- Precision is Key: Ensure you are stopping precisely on each number of the combination. Even a slight deviation can prevent the lock from opening.
- Correct Sequence: Confirm you are following the exact opening sequence: clockwise to the first number, counter-clockwise past zero once then to the second number, and clockwise directly to the third number.
- Clear the Lock: Always perform the initial two or more full clockwise turns to clear the mechanism before entering the combination.
- Shackle Pull: After entering the combination, ensure you are pulling the shackle firmly upwards.
Dial is Stiff:
- Cleanliness: Dirt or debris might be obstructing the dial's movement. Clean the lock as described in the Maintenance section.
- Lubrication: Apply a small amount of graphite or silicone-based lubricant to the dial mechanism if it remains stiff after cleaning.
