Remove screw that lowers jack
Open the drain screw that holds the body of the hydraulic jack. This way you can addhydraulic oil to the hydraulic jack.
lossen the plug and pump handle slowly till fluid comes out, tighten plug.
Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.
Hydraulic jacks have the advantage of working quickly to raise or lower items like autos. A hydraulic jack is filled with fluid and can lift heavier loads while using less force.
you can but you'll be buying a new one very shortly afterwards. Use hydraulic fluid. Brake fluid works well also

Hydraulic Jack oil
A scissor jack uses a fine threaded screw and mechanical advantage to lift a vehicle. A hydraulic jack uses hydraulic fluid, a pump, and a cylinder to lift the car.
Should be a screw at the side of the jack body Make sure piston is in collapsed position and fill with hydraulic jack oil to this level
designed for hydraulic jack perhaps power steering fluid would work Brake fluid Ruins pump
Use "Hydraulic Jack Oil" only
No, use only the appropriate fluid or the jack may fail, killing you.
For most floor and bottle style jacks, you can get hydraulic fluid at most hardware stores. I work at Ace Hardware and we carry it in 20 oz. and gallon containers. The Ace item number for the 20 oz. bottle is 85435. Gary

No. Only hydraulic oil can be used in hydraulic jacks. Hydraulic oil is compressed (a requirement for use in hydraulic cylinders) so that there are no air or other gases dissolved in it. Before adding hydraulic fluid to the jack, be certain that the fluid has been sitting for at least 24 hours to avoid introducing air into the hydraulic fluid in the chamber.You should be able to purchase hydraulic oil (sometimes it will be labeled "Hydraulic Jack Oil/Fluid or Jack Oil/Fluid) in small or large quantities, inexpensively, at any auto parts store worthy of the name. It can also be purchased at some Walmarts and any heavy equipment supply stores.
Remove the fill plug and top it off with hydraulic oil.
Via the fill and drain bolts on the tranmission assembly. The are easily accessable with a floor jack or ramps, but make sure the car is level when changing the fluid.
