Used jack to level a house. Just all day for 2 days with no issues or leaks. Also used on 18 wheeler multiple times with good service. Jack is tall and heavy so keep that in mind if considering purchasing.
Found this while looking for a jack for my homemade shop press. It works great when it's warm but not so much when it's cold. I had to take apart the pneumatic part and clean some of the "grease" out to make it work better. I will have to take it apart periodically to regrease it.
After unboxing, the hydraulic pump worked but the pneumatic motor did not. The diagram looked simple enough so I disassembled the air motor. The piston was very, very tight. I removed all the grease and cleaned the cylinder and piston, replaced with pneumatic oil, also primed the small pneumatic piston with oil, reassembled and then it worked. I didn't want to be bothered with returning the item. Pneumatic function is slower than expected at 150psi. Possibly because the factory air fitting is a larger diameter than what I have on all my other air tools.
I absolutely hate jacking up cars with the jacks that come with them. This one here is a huge time and effort saver. It takes a lot more air from my compressor than I thought it would, but still does the job just fine. Highly recommend.
