If your Craftsman Jack will not lower after unloading, it could be due to an overfilled oil reservoir. Try draining the fluid to the proper level. Another possibility is binding linkages. In this case, clean and lubricate the moving parts.
Why does my Craftsman Jack bleeds off after lift?
If your Craftsman Jack is bleeding off, meaning it starts to lower after lifting, there could be a couple of reasons. First, check that the release valve is tightly closed. If that's not the issue, it's possible there's a hydraulic unit malfunction, in which case you should replace the power unit assembly.
What to do if my Craftsman Jack has poor lift performance?
If your Craftsman Jack isn't lifting properly, it might be due to a low fluid level. Make sure the fluid level is at the correct level. Also, there could be air trapped in the system. To resolve this, fully retract the ram, open the release valve, and pump the handle several times to expel any trapped air.
