Setup
Setting Your TSA Combination Lock
Your Coolife hardside luggage comes equipped with a built-in TSA-approved combination lock for enhanced security. Follow these steps to set your personal combination:
- The lock is preset to 0-0-0.
- Locate the reset button (a small, recessed button) on the side or top of the lock. Use a pen or a pointed object to press and hold this button.
- While holding the reset button, rotate the dials to your desired 3-digit combination. Choose a memorable number.
- Release the reset button. Your new combination is now set.
- To lock, align your chosen combination. To unlock, align your chosen combination and press the release button.
Important: Do not forget your combination. There is no master key for personal combinations. Only TSA agents have a universal key to open the lock without damaging it.

Operating Instructions
Using Spinner Wheels and Retractable Handle
Your Coolife luggage features four multi-directional spinner wheels and a sturdy retractable handle for effortless mobility.
- Spinner Wheels: The 360-degree spinner wheels allow the luggage to glide smoothly in any direction, reducing strain on your arm and shoulder. You can push, pull, or roll the suitcase alongside you with ease.
- Retractable Handle: To extend the handle, press the button located on the top of the handle and pull upwards. To retract, press the button again and push the handle down until it locks into place. Ensure the handle is fully extended or retracted before moving the luggage to prevent damage.

Internal Organization and Additional Bags
The luggage features a fully-lined interior with divider and organization pockets to keep your belongings secure and tidy. The accompanying duffel bag and toiletry bag are designed for convenience and versatility.
- Interior Divider: Use the zippered divider to separate contents within the main compartment, such as clean and dirty clothes, or to keep items from shifting during transit.
- Organization Pockets: Utilize the various mesh and zippered pockets for smaller items, toiletries, or accessories, ensuring easy access and preventing clutter.
- Duffel Bag & Backpack: These bags are made of mild water-resistant polyester fabric. They feature a back sleeve that allows them to be conveniently attached to the retractable handle of your hardside luggage, making airport navigation simpler.
- Toiletry Bag: Ideal for organizing personal care items, this bag fits neatly inside the larger luggage or can be carried separately.

Maintenance
Cleaning and Care
Proper care will extend the life and appearance of your Coolife luggage set.
- Hardside Shell (ABS): For general cleaning, wipe the exterior with a soft cloth dampened with mild soap and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish. For scuffs, a magic eraser or a small amount of rubbing alcohol on a soft cloth can often remove marks.
- Fabric Bags (Polyester): The duffel and toiletry bags can be spot cleaned with a damp cloth and mild detergent. Allow to air dry completely. Do not machine wash or tumble dry.
- Wheels: Periodically check the wheels for any debris (hair, lint, etc.) that might hinder smooth rolling. Clean as needed.
- Zippers: Ensure zippers are free of debris. If they become stiff, a small amount of zipper lubricant or wax can help.
- Storage: When not in use, store your luggage in a cool, dry place, away from direct sunlight. Nesting smaller pieces inside larger ones can save space.

Troubleshooting
If you encounter any issues with your Coolife Suitcase Set, please refer to the common solutions below. If the problem persists, contact customer support.
| Problem | Possible Cause / Solution |
|---|---|
| TSA Lock not opening/resetting. | Ensure the correct combination is aligned. If resetting, ensure the reset button is fully pressed before setting a new combination. If the combination is forgotten, the lock cannot be opened without the correct code or by TSA. |
| Wheels not rolling smoothly. | Check for debris (hair, lint, dirt) caught in the wheel mechanism. Clean thoroughly. If a wheel is damaged, contact customer support. |
| Retractable handle is stuck or wobbly. | Ensure the release button is fully pressed when extending or retracting. Avoid forcing the handle. If it feels excessively wobbly, it may be due to normal play in telescopic handles, but if it impacts functionality, contact support. |
| Zippers are difficult to move. | Check for fabric caught in the zipper teeth. Apply a small amount of zipper lubricant (e.g., beeswax, silicone spray) to the teeth. |
| Exterior scuffs or marks. | For minor scuffs on the ABS hardshell, use a damp cloth with mild soap, or a magic eraser. Some deeper scratches may be permanent due to normal wear and tear during travel. |
