6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your scooter:
- Battery Care: For lead-acid batteries, regular maintenance is crucial. Charge the battery after each use. Store the battery fully charged and recharge every 1-2 months if not in use to prevent performance degradation.

- Brake Inspection: Regularly inspect the electronic braking system for any signs of wear or malfunction.
- General Check: Periodically check all nuts, bolts, and connections to ensure they are secure.

If you encounter any issues with your scooter, please refer to the following common troubleshooting tips:
- Scooter Not Powering On: Check if the main power breaker is in the 'ON' position. Ensure the battery is charged and properly connected.
- Reduced Range/Power: This often indicates a low battery charge. Ensure the battery is fully charged before use. Battery performance can degrade over time; consider battery replacement if issues persist after proper charging.
- Unusual Noises: Inspect for loose components, worn tires, or issues with the motor or suspension. Contact customer support if the noise persists.
- Braking Issues: If braking feels unresponsive or inconsistent, check the brake levers and the electronic braking system. Do not operate the scooter if brakes are not functioning correctly.
