5. Maintenance

• Cleaning the Exterior: Wipe the hard shell surface with a soft, damp cloth and mild soap. Avoid using abrasive cleaners or solvents that could damage the finish.
• Zippers: Periodically check the YKK zippers for any debris or fabric snags. Clean them gently if necessary. If zippers become stiff, a silicone-based lubricant can be applied sparingly.
• Wheels: Inspect the spinner wheels regularly for accumulated hair, lint, or debris. Remove any obstructions to ensure smooth rolling.
• Handles: Keep the telescopic handle clean and free of debris. Do not force the handle if it feels stiff.
• Storage: Store your luggage in a cool, dry place away from direct sunlight when not in use. If you have multiple pieces, they can be nested inside each other for compact storage.

6. Troubleshooting

• TSA Lock Not Opening: Double-check that you are entering the correct 3-digit combination. If you have forgotten your combination, contact Coolife customer support for assistance.
• Telescopic Handle Stuck: Ensure no items are obstructing the handle mechanism inside the luggage. Gently try to extend and retract the handle. If it remains stuck, a small amount of silicone spray can be applied to the extending rods. Do not apply excessive force.
• Wheels Not Rolling Smoothly: Remove any hair, lint, or debris that may be caught in the wheel axles. If a wheel is visibly damaged, contact customer support.
• Zipper Issues: Avoid overpacking the luggage, which can strain the zippers. If a zipper is misaligned, gently pull it back and forth to try and realign the teeth.
