Setup
Setting the TSA Combination Lock
Your Kono luggage comes with a pre-set combination lock set to 0-0-0. Follow these steps to set your personal combination:
- Turn the dials to the factory default setting: 0-0-0.
- Locate the reset button (usually a small hole) on the side of the lock. Use a pen or a pointed object to press and hold the reset button.
- While holding the reset button, set your desired 3-digit passcode by rotating the dials. Choose a memorable combination.
- Release the reset button. The switch button should pop back up. Your new passcode is now set. Test it by scrambling the numbers and then entering your new code to open the lock.

Using the Expansion Feature
To expand the luggage, locate the secondary zipper around the perimeter of the suitcase. Unzip this zipper to extend the fabric gusset, providing an additional 2 inches of packing space. To return to the original size, zip the expansion zipper closed.
Carrying Handles
Use the top and side carry handles for lifting the luggage when rolling is not feasible, such as when placing it in overhead compartments or lifting it onto a baggage carousel. Ensure both handles are securely gripped for balanced lifting.

Maintenance
Cleaning the Exterior
To clean the hard shell exterior, wipe with a soft cloth dampened with mild soap and water. Avoid abrasive cleaners or solvents, as these can damage the finish. Dry thoroughly with a clean cloth.
Wheel Care
Periodically check the wheels for any debris (hair, lint, dirt) that may hinder smooth rolling. Remove any obstructions carefully. If wheels become stiff, a small amount of silicone-based lubricant can be applied to the axle.
Zipper Maintenance
Keep zippers clean and free of debris. If a zipper becomes stiff, apply a small amount of zipper lubricant or wax to the teeth to ensure smooth operation.
Storage
Store your luggage in a cool, dry place away from direct sunlight when not in use. Avoid placing heavy objects on top of the luggage for extended periods to prevent deformation.
Troubleshooting
- Wheels not rolling smoothly: Check for debris caught in the wheels. Clean as per maintenance instructions. If the issue persists, apply lubricant.
- Zipper jamming: Ensure the zipper path is clear of fabric or other obstructions. Apply zipper lubricant if needed. Avoid forcing the zipper.
- Telescopic handle sticking: Ensure the release button is fully pressed when extending or retracting. Check for any foreign objects obstructing the handle mechanism.
- TSA lock not opening: Double-check that you are entering the correct 3-digit combination. If you have forgotten your combination, you may need to contact Kono customer support for assistance, as there is no universal reset key for personal combinations.
