3. Setup and First Use
Setting the TSA-Approved Lock
Your Coolife suitcase is equipped with a mounted TSA-approved combination lock for enhanced security. The default combination is 0-0-0.
- Set the dials to the default combination (0-0-0).
- Locate the reset button (usually a small, recessed button on the side of the lock). Use a pen or a pointed object to press and hold this button.
- While holding the reset button, set your desired 3-digit combination by turning the dials.
- Release the reset button. Your new combination is now set.
- To lock, align your chosen combination and insert the zipper pullers into the lock slots. Scramble the numbers to secure.
- To unlock, dial your set combination and press the release button (usually a larger button or lever next to the dials).

Retractable Handle
The luggage features a retractable handle for easy maneuverability. Press the button on the handle to extend or retract it to your desired height. Ensure it clicks securely into place when extended or fully retracted.
4. Operating Instructions
Effortless Mobility with Spinner Wheels
Each suitcase is equipped with four multi-directional spinner wheels, allowing for smooth 360-degree rotation and effortless gliding through airports and various terrains. These wheels are designed for stability and ease of movement, reducing strain on your arm and shoulder.

Interior Organization
The fully-lined interior of each suitcase includes a zippered divider and organization pockets to keep your belongings secure and neatly arranged. Use the adjustable buckle straps to compress and hold your clothes in place, preventing shifting during transit.

Duffel Bag and Toiletry Bag Features
The duffel bag and backpack (if included in your set) are made of mild water-resistant polyester fabric. Both are designed with a back sleeve, allowing them to be conveniently attached to the retractable handle of your suitcase for easy transport. The backpack also features multiple functional pockets for various travel needs.

5. Maintenance
Cleaning the Hardside Shell (ABS)
- Wipe the exterior with a soft cloth dampened with mild soap and water.
- Avoid abrasive cleaners or solvents, as they may damage the surface.
- For stubborn marks, a magic eraser can be used gently.
Cleaning Fabric Bags (Polyester)
- Spot clean with a damp cloth and mild detergent.
- Allow to air dry completely before storage. Do not machine wash.
Wheels and Zippers
- Regularly check wheels for debris and clean as needed.
- Lubricate zippers periodically with a silicone-based spray to ensure smooth operation.
6. Troubleshooting
Stuck Wheels
- Check for hair, lint, or other debris wrapped around the wheel axles. Carefully remove any obstructions.
- Ensure wheels are not bent or damaged.
Jammed Zippers
- If the zipper is stuck, try gently wiggling the puller back and forth.
- Apply a small amount of lubricant (like graphite from a pencil or zipper lubricant) to the teeth.
TSA Lock Issues
- If you forget your combination, unfortunately, there is no master key or universal reset. You may need to try common combinations or contact a locksmith.
