Hi Guys Brian from Expressimo Audio .
You should always email the manufacture when something is not working. I personally go out of my way to make things right or refund your money. If the Lift is not LIFTING the arm it is simple email me I have custom head weights and I have the NEW Project Music Hall Lift with more Lift force. I would have gladly helped you. If you still need help email me. My Father Sal C passed away 5 years ago.
