Hello, I am sorry no one could help you earlier. If you still need help, please post the full machine serial number with your reply.

Oil level does not effect controls, the problem could be the lockout switch is on or you have a problem with the hydraulic pump.

Does the steering work correctly?

Do any loader functions work?

Do the stabilizer controls work?

What type oil did you use?
