Is the mast elevated? If so and it won't lower it sounds like it is a problem with the velocity fuse which is located at the base of the cylinder behind the hose fitting. If the mast in elevated and won't come down then you will have to jack up the mast to take the pressure off the cylinders and it should come down.
