When did you purchase your product? Tampering with it can cause the warranty to be voided. I wouldn’t recommend tampering with it and risking damages or injury.
We’re not able to provide instructions on how to take apart the scooter in the manner you’re describing. You might need to contact a technician to help you fix the issue, I’m sure it would be a quick fix. You may visit https://www.statewidemobility.com and they can provide you with a tele-diagnostic service or in home service.
Hope this was helpful, have a great day!
