If you are experiencing abnormal motor noise in your V40, don't worry, we are here to help. Follow these steps to troubleshoot the issue and get your scooter back to its normal, smooth operation.

Firstly, check if the tire pressure is normal and if there are any foreign objects inside the tire. Low tire pressure or foreign objects inside the tire can cause abnormal noise while riding . If you find any issues, make sure to address them immediately.

Next, check if the screws are tightened in place. Loose or missing locks can cause abnormal noise, so make sure to re-lock them if necessary.

Thirdly, check for foreign objects and deformation of materials at the location of the abnormal noise. Any foreign objects or deformations can cause abnormal noise, so make sure to inspect the area thoroughly.

Fourthly, check if the lubrication at the abnormal sound position is sufficient. If not, increase the lubrication to reduce friction and eliminate the abnormal noise.

Lastly, if the abnormal noise comes from inside the motor, disassemble it for inspection or replace the motor. This is a more complex task, so it's recommended to take your scooter to an authorised Service Location.

By following these steps, you can troubleshoot and eliminate abnormal motor noise in your V40. If you have any further questions or concerns, don't hesitate to contact our customer support team for assistance.
