OK. I will examine the elements you mention to me. (At the moment I do not have the Linde program.) Thank you very much!

Sounds as though you do have an error code but you have to have Linde program to retrieve it
However there are a couple of things you can check
1- pull up floorplate and check the tilt angle sensor wires it is located on right hand side (sitting in seat )above drive wheel
2 - check the wiring etc to the hyd temp sensor switch it is located on return to hyd tank good luck !

you need one laptop
