Hi, yes I had All covers off. The only books within the machine were the operator manual in the pouch by the floor plate. The other book is beneath the floor plate is a parts manual in the plastic tube. It seems maybe the agent here removes the service Manuals so clients do not have access to them and only the service department does.

Anyway, I managed to find the fault.
The mast cable on the right hand side when in the operation position took a pinch where the small bracket holds it to the mast. ( lift the platform up).

Thanks :)
