531. 70 problem

[Bullbeeef]

2012 jcb 531 70. Joystick controls are all jumpy and delayed ( boom up/down in/out crowd ect)

I can wait 5 seconds before any movement sometimes and it’s very jumpy. Cleaned all the connections off but still no luck ?


Also the pick up hitch won’t lift 10 bales on a trailer unless it’s moving forward??
Any pointers? Tia

Pick up hook only has 2 ton lift

Is the pump cavitating? Air in hyd oil.

@ACEngineering thanks I’ll have a look in the morning. How do I go about sorting that out if thats the issue?
