My Lift has a New Life.
Bought the 6K half height lift three years ago, but didn't use it much after installation, though I checked it out for full operation - it worked fine. After sitting unused for a coupe of years the unit would not lift when loaded, but would half heartedly lift when unloaded. I tried to trouble shoot the issue. No joy. I ended up ordering and replacing the power unit for the lift.
It now works like a champ. It raises my car projects all the way to the four foot height in about 90 seconds. It is very stable and offers plenty of room underneath the car to do major work. I'm very happy with how it's working now, just wish I didn't have to replace the power unit. Will definitely look into getting the old power unit refurbished, to keep it on hand.
