Setup
Unpacking and Nesting
Your luggage set is designed for efficient storage. The smaller suitcases are nested inside the larger ones upon delivery. To access all pieces, simply open the largest suitcase and remove the nested items. When not in use, you can re-nest the suitcases to save space.
Telescoping Handle Adjustment
Each suitcase is equipped with an adjustable telescoping 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 downwards until it is fully collapsed. The handle has multiple locking positions for comfortable use by various users.

360° Spinner Wheels
The luggage features four 360° multi-directional spinner wheels for smooth and effortless maneuverability. These wheels allow the suitcase to glide in any direction, reducing strain during transit. Ensure no debris is caught in the wheels for optimal performance.

Operating Instructions
Setting the TSA-Approved Combination Lock
Your Coolife luggage comes with a built-in TSA-approved combination lock. The initial combination is set to 0-0-0.
- Open the lock by sliding the release button (usually on the side of the lock) or entering the default 0-0-0 combination and pressing the release button.
- With the lock open, locate a small reset button or lever (often recessed and requiring a pen tip to press). Press and hold this button/lever.
- While holding the reset button/lever, set your desired 3-digit combination by turning the dials.
- Release the reset button/lever. Your new combination is now set. Test the new combination to ensure it works correctly before scrambling the dials.
Note: Only TSA agents can open your luggage without damaging the lock using a special key. Do not attempt to force the lock if you forget your combination.

Utilizing the Interior
The luggage interior is fully lined and features mesh zipper pockets and elastic straps. Use the mesh pockets for smaller items, toiletries, or documents. The elastic straps help secure your clothing and prevent shifting during travel, keeping your belongings organized.

Maintenance
Cleaning the Exterior
To clean the hardshell exterior, wipe with a damp cloth and mild soap. For stubborn marks or scuffs, a gentle cleaner designed for ABS plastic can be used. Avoid abrasive cleaners or harsh chemicals, as these may damage the surface finish.
Care for Wheels, Zippers, and Handle
- Wheels: Periodically check the spinner wheels for any trapped debris (e.g., hair, lint) and remove it to ensure smooth rolling.
- Zippers: Keep zippers clean and free of obstructions. If a zipper becomes stiff, a small amount of zipper lubricant or wax can be applied.
- Handle: Ensure the telescoping handle extends and retracts smoothly. If it becomes sticky, clean the shafts with a damp cloth. Do not apply excessive force.
Troubleshooting
Common Issues and Solutions
- Scuffs and Surface Marks: Minor scuffs from handling can often be reduced by wiping with a damp cloth and mild soap. For deeper marks, a plastic polish may help.
- Dents in Hardshell: For minor dents, some users have reported success by gently applying heat with a hairdryer on a low setting and carefully pushing the dent out from the inside. Exercise caution to avoid overheating the material.
- Stiff Telescoping Handle: If the handle does not extend or retract smoothly, ensure the release button is fully depressed. Clean any visible dirt or grime from the handle shafts.
- Wheels Not Rolling Smoothly on Carpet: Spinner wheels perform best on hard, smooth surfaces. On carpeted areas, you may need to tilt the luggage and pull it on two wheels.
