Floor Jack Goes Down By Itself

I have a 3 ton craftsman jack that i got from sears as a jack stand creeper.

Floor jack goes down by itself. 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. In this video i demonstrate how to remove air from your hydraulic jack and fixes it from bleeding down. Refer to the owner s manual of your floor jack to ensure the level and measurement is correct. Use only a quality grade hydraulic floor jack oil do not use regular oil products.

Can anyone explain how i can fix my floor jack so can build up pressure. I figure it is like bleeding brakes but don t know how to do it with a floor jack. I will assume you are talking about the roll around jack used in garages and the bottle jack. I also need to put the cover on the hydro fluid reservoir.

The jack will not even lift its arm by itself let alone the weight of an axle. The oil level should be between 3 16 to a 1 4 of an inch above the cylinder on most floor jack models. 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.
