2 post lift won't lower

[DWinTX]

Hey guys,

A year or so ago I bought a refurbished lift from a local lift installation/repair company. It is an older Nussbaum. Not sure of the model but I think it's an SPL-7000 from looking at pics on the web.

It has worked flawlessly, until yesterday. I needed to get the arms out of the way for something I was doing in my small shop, so I raised them up unloaded. Now they won't lower. I think this is the first time I've ever raised them without a car on them. I tried hanging on them, I attached a tie down strap to the bumper of my car and tried cranking them down. Neither worked.

This is my first lift. Is this a common problem? Any idea how to get them down? I can call the lift company back out, but I'll have to pay a service fee as there was only a 90-day warranty being it's a used lift.

check to make sure your not on one of the locks then have someone stand on it to add weight as you lower if

Definitely not on the locks.

I braced the control lever to the lower position (to open the hydraulic valve), and hung from the arms. The tie down I mentioned above was wrapped around the arms on one end and the bumper of my car on the other. I cranked it till I couldn't any more and it didn't budge. I'm sure that was putting several hundred pounds of pressure on it. It's the kind of tie down you use to tie a car down on a trailer. Heavy duty.
