I have a Craftsman hydraulic floor jack that won’t release the ram once its pushed in/down. Anybody repair one of these before? Its a nice jack and when it works, it works great. Puts my other jacks to shame.

And yes I went to Sears and they don’t warranty jacks like they do tools.

After doing some quick research, one site says to use Mobil DTE Light or DTE 24s or Shell Turbo 32

Appears my jack may have a bad check valve.
