I just bought a used Hoveround MPV4, but there was no manual included. I hope this isn't a really stupid question, but here goes:

To charge the batteries, do you plug the charger into an electrical socket, let it charge up, and then plug the charger into the wheelchair. Or, do you plug in the charger and then plug in the socket in the wheelchair?

Also, will Hoveround sell me a manual even though I bought the wheelchair second-hand.

Thanks in advance for any advice!
