I have a floor jack that’s malfunctioning. It was purchased from Walmart several years ago so it’s certainly not a high quality unit, but I would like to get it back into service if possible. It will rise easily when unloaded, and will start to bear the weight of the vehicle a bit, but once it unloads the springs a tad it won’t life any further.
When it first started doing this I could “reset“ it by fully raising it, barely opening the valve and then standing on it so it slowly lowered. Sometime it took a couple of tries before it would start lifting again. I tried to use it today and it wouldn’t life even after several up and down cycles.
Any suggestions on troubleshooting? I know absolutely nothing about the inner workings of hydraulic jacks other than understanding the basic principles of hydraulics from a physics perspective.
