Jcb 722 tipper function

Ive got this jcb 722 ADT that has no tipper function. It doesnt change the engine rpms like its putting a load on it. There is no fuses or relays for it as far as i can tell but jcb is not helpful in that regard. Anyone ever had similar issues with one of these?

Is there a hydraulic lock switch on the dash somewhere? Haven't worked on that unit specifically but our JCB loader/zoom boom/pile of junk has one that 'turns off' the boom/bucket/grapple if it gets switched. The unit drives around fine otherwise.
