3. Setup: Setting Your TSA Combination Lock
Your COOLIFE luggage comes with a built-in TSA-approved combination lock. The initial combination is set to 0-0-0. Follow these steps to set your personal combination:
- Ensure the lock is set to the default combination 0-0-0.
- Locate the small reset button (often a small hole) on the side or top of the lock. Use a pen or a pointed object to press this button until you hear a 'click' sound.
- While the reset button is pressed, set your desired 3-digit combination by turning the dials to your chosen numbers.
- Release the reset button by pushing the shackle or the side release tab. You should hear another 'click' sound.
- Your new combination is now set. Scramble the dials to lock, and use your new combination to unlock.
Important: Remember your combination. There is no master key for personal combinations, and the manufacturer cannot assist in resetting it if forgotten.

4. Operation
4.1. Telescopic Handle
The luggage features an adjustable 3-level 100% pure aluminum telescoping handle. To extend, press the button on the handle grip and pull upwards. To retract, press the button and push downwards until fully collapsed. Ensure the handle is fully extended or retracted before moving the luggage.

4.2. Spinner Wheels
Equipped with quiet airplane spinner wheels, your luggage can be effortlessly maneuvered in any direction. These wheels provide smooth 360-degree rotation, enhancing stability and ease of transport. For best performance, push the luggage upright rather than tilting and pulling.
4.3. Expandable Capacity (28-inch model only)
The 28-inch suitcase includes an expandable zipper section, increasing its capacity by approximately 15%. To expand, locate the secondary zipper around the perimeter of the suitcase and open it. To return to standard size, close this zipper.

4.4. Interior Organization
The fully-lined interior features a zippered divider, mesh pockets, and elastic cross straps. Use the zippered divider to separate contents, mesh pockets for smaller items, and cross straps to secure clothing and prevent shifting during transit.

5. Maintenance and Care
- Cleaning the Exterior: Wipe the hard shell exterior with a soft, damp cloth and mild soap. Avoid using abrasive cleaners or harsh chemicals, as these can damage the finish.
- Cleaning the Interior: The interior lining can be spot cleaned with a damp cloth and mild detergent. Allow to air dry completely before closing.
- Wheel Maintenance: Periodically check the spinner wheels for any accumulated dirt, hair, or debris. Remove any obstructions to ensure smooth rolling.
- Handle Care: Keep the telescopic handle free from dirt and debris. If it becomes stiff, a small amount of silicone-based lubricant can be applied to the extending rods.
- Storage: When not in use, store your luggage in a cool, dry place away from direct sunlight. The smaller suitcases can be nested inside the larger ones for compact storage.
6. Troubleshooting
Common Issues and Solutions:
- TSA Lock Not Opening: Double-check that the correct 3-digit combination is entered. Ensure each dial clicks into place. If the combination was forgotten, the lock cannot be reset without the correct code.
- Telescopic Handle Sticking: Check for any visible obstructions or debris in the handle mechanism. Gently pull and push the handle several times. If needed, apply a small amount of silicone spray lubricant to the extending parts.
- Wheels Not Spinning Smoothly: Inspect the wheels for hair, lint, or other debris caught in the axles. Carefully remove any obstructions. Ensure the luggage is not overloaded beyond its capacity.
- Zipper Issues: If a zipper is stuck, avoid forcing it. Gently pull the fabric away from the zipper teeth and try to move the slider. Ensure the zipper teeth are properly aligned.
