Floor Jack Goes Down By Itself

Can anyone explain how i can fix my floor jack so can build up pressure.

Floor jack goes down by itself.

Floor jack best for general use like working on cars easier to use can get lower more stable can roll around with weight on it more stable lift platform hydraulic jack greatest weight lift also called bottle jacks greater lift potential while i have given you what. Both mention jacks are hydraulic. I will assume you are talking about the roll around jack used in garages and the bottle jack. On his you can pump the jack up and wherever you leave the handle it will stay in place and will not move when weight is applied.

The jack will not even lift its arm by itself let alone the weight of an axle. I figure it is like bleeding brakes but don t know how to do it with a floor jack. Try it if yours has the same symptoms it just may fix. I have a 3 ton craftsman jack that i got from sears as a jack stand creeper.

I also need to put the cover on the hydro fluid reservoir. So after using a friend s floor jack i noticed that mine behaved in a different way. Remove the oil fill plug and look into the chamber. The oil level should be between 3 16 to a 1 4 of an inch above the cylinder on most floor jack models.
