Setup and Adjustment
1. Sizing and Head Circumference Measurement
To ensure optimal protection, select the correct helmet size. Measure your child's head circumference approximately 1 cm above the ear, at the widest part of the head.
- Size S: 19.3-22 inches (49-56 cm)
- Size M: 22-22.8 inches (56-58 cm)

2. Fitting the Helmet
- Place the helmet on your child's head, ensuring it sits level and covers the forehead.
- Adjust the 360° regulator at the back of the helmet by turning it right to tighten or left to loosen. The helmet should feel snug but comfortable, without excessive movement.
- Fasten the chin strap buckle. Adjust the straps so they form a 'V' shape under the ears and are snug against the chin without causing discomfort. Only one finger should fit between the strap and the chin.

3. Attaching and Detaching the Chin Guard
The helmet features a removable chin guard for versatile use:
- To Detach: Locate the buttons on each side of the chin guard where it connects to the main helmet. Press these buttons firmly and pull the chin guard downwards and away from the helmet.
- To Attach: Align the connectors on the chin guard with the slots on the helmet. Push the chin guard upwards until you hear a click on both sides, indicating it is securely fastened.

Operation
Once the helmet is properly fitted and adjusted, it is ready for use. Ensure the chin guard is attached for activities requiring full-face protection (e.g., mountain biking, BMX) or detached for more casual riding (e.g., balance bike, scooter).
Maintenance
1. Cleaning
- Outer Shell: Wipe the exterior with a soft cloth dampened with mild soap and water. Do not use abrasive cleaners or solvents.
- Inner Padding: The helmet features a removable and washable inner liner. Detach the padding and hand wash it with mild soap and water. Allow it to air dry completely before reinserting.

Troubleshooting
