Setup
Setting Up Your TSA Combination Lock
Your luggage is equipped with a TSA-approved combination lock. Follow these steps to set your personal combination:
- The lock is preset to 0-0-0.
- Locate the small reset button (usually a small hole) on the side of the lock. Use a pen or pointed object to press and hold this button until you hear a "click".
- While holding the reset button, set your desired 3-digit combination by turning the dials to your chosen numbers.
- Release the reset button. Push the main button (usually a larger button or slider) in the direction of the arrow until you hear another "click" to confirm the new combination.
- Your personal combination is now set. Remember your combination as there is no master key.

Expanding the 28-inch Suitcase
Only the large 28-inch suitcase in your set features an expansion zipper. To expand, simply unzip the secondary zipper located around the perimeter of the suitcase. This will provide an additional 15% of packing space.

Maintenance
Exterior Care
The ABS hardshell exterior is designed to be durable and scratch-resistant. To clean, wipe the surface with a soft, damp cloth using mild soap. Avoid using harsh chemicals or abrasive cleaners, as these can damage the finish.
Zippers
For optimal performance, ensure that the zippers are kept clean and free from debris. If a zipper becomes stiff, a small amount of silicone-based lubricant or even rubbing a pencil lead along the teeth can help restore smooth operation.

Wheels and Handles
Periodically inspect the spinner wheels and telescopic handle for any signs of wear or damage. Clean any accumulated dirt, hair, or lint from the wheel mechanisms to maintain smooth rolling. Ensure the telescopic handle extends and retracts freely without obstruction.
Troubleshooting
Wheels Not Rolling Smoothly
If the wheels are not gliding smoothly, check for any debris (such as hair or lint) caught in the wheel axles. Carefully remove any obstructions. If the issue persists or wheels are damaged, contact customer support.
Telescopic Handle Jammed
Ensure that no items inside the luggage are pressing against or obstructing the handle mechanism. Press the release button firmly while gently wiggling the handle to extend or retract it. Avoid excessive force.Combination Lock Issues
If you forget your combination, unfortunately, there is no master key to open the lock. You may need to contact a locksmith or the airline for assistance. Always ensure your combination is noted down in a secure place.
