- Unfolding the Frame: Carefully unfold the aluminum frame until it locks into its open position. Ensure all locking mechanisms are securely engaged.
- Attaching the Wheels: The four EVA material wheels are easily detachable for compact storage. To attach, align each wheel with its axle and push firmly until it clicks into place. Ensure all wheels are securely fastened before use. The front wheels are designed to swivel 360 degrees for enhanced maneuverability.

Maintenance
- Cleaning the Bag: The removable bag is made of waterproof material. It can be wiped clean with a damp cloth and mild soap. Do not machine wash or tumble dry. Ensure the bag is completely dry before reattaching it to the frame.
- Frame and Wheels: Wipe the aluminum frame and EVA wheels with a damp cloth to remove dirt and debris. Avoid using abrasive cleaners. Periodically check that all wheel axles are free of obstructions and rotate smoothly.
- Storage: When not in use, fold the trolley compactly and store it in a dry place, away from direct sunlight and extreme temperatures. The removable wheels can be detached for even more compact storage.
Troubleshooting
This section addresses common issues you might encounter with your CARLETT Lett450 shopping trolley.
- Wheels not rotating smoothly: Check for debris (e.g., hair, lint) caught in the wheel axles. Clean as necessary. Ensure wheels are properly attached and locked into place.
- Handle not adjusting: Ensure the release button for handle adjustment is fully pressed. Check for any obstructions in the adjustment mechanism.
- Trolley does not fold/unfold easily: Verify that no parts are obstructed. Ensure the safety lock is disengaged before folding. Apply gentle, even pressure.
