4. Operating Instructions
4.1 Using the Telescopic Handle
The aluminum telescopic handle can be adjusted to multiple heights for comfortable maneuvering. Press the button on the handle to extend or retract it. Ensure the handle is fully extended or retracted before moving the luggage to prevent damage.
4.2 Maneuvering with Spinner Wheels
Your Merax luggage features multi-directional 360-degree spinner wheels. These wheels allow for effortless gliding in any direction, reducing strain on your arm and shoulder. Push the luggage upright on all four wheels for smooth movement through airports and other surfaces.
4.3 Utilizing the Expansion Feature
The 24-inch and 28-inch suitcases include an expansion zipper. To expand the luggage, simply unzip the expansion zipper located along the perimeter of the suitcase. This will provide additional packing space when needed. To return to the original size, zip the expansion zipper back up.

- Zippered Pockets: Additional zippered pockets are available for smaller items, toiletries, or accessories.
- Elastic Compression Straps: Use the elastic clothing compression straps to secure your clothes and minimize shifting during transit.

5. Maintenance
5.1 Cleaning the Hard Case
To clean the exterior of your hard case luggage, simply wipe it down with a damp cloth and mild soap. Avoid using harsh chemicals or abrasive cleaners, as these can damage the ABS material and UV protective coating.
5.2 Wheel and Handle Care
Regularly check the spinner wheels for any debris or hair that might impede their movement. Clean them as needed. Ensure the telescopic handle extends and retracts smoothly. If it becomes stiff, a small amount of silicone-based lubricant can be applied to the shafts.
5.3 Zipper Maintenance
Keep zippers clean and free of obstructions. If a zipper becomes stiff, apply a small amount of zipper lubricant or wax to the teeth.
6. Troubleshooting
- Sticking Telescopic Handle: If the handle does not extend or retract smoothly, ensure no items are obstructing the mechanism inside the lining. Apply a small amount of silicone lubricant if necessary.
- Wheels Not Spinning Freely: Check for tangled hair, lint, or debris around the wheel axles. Clean them thoroughly.
- Zipper Malfunction: Ensure the zipper teeth are aligned. If they are misaligned or stuck, gently work the slider back and forth with a zipper lubricant. Avoid forcing the zipper.
- TSA Lock Issues: If you forget your combination, refer to the lock setting instructions to reset it. TSA agents can open the lock with a master key without damaging your luggage.
