Just bought it and would need service & parts manuel or info swing brake operation air over hydraulic system are the joy stick sending air to hydraulic actuators
Congratulations on your purchase let the game begin, parts are hard to find info manuals very hard to come by, l recently bought atlas 2003 ab looks very similar, l have some documentation mostly parts diagrams, what country are you in, im in Australia, can you put some photos up of your machine, l assume yours will be same as mine swing brake is operated by foot peddle and hydraulic tank has air over hydraulic.
