lör 14 sep 2024, 13:40#855818 Hello, I have a problem with GREMO 950R. it shows me this error as soon as i turn on the ignition, after starting the engine, the numbers jump to
27-32. I suspect problem with the sensor. Maybe someone can advise which sensor might be broken? P.S I bought forwarder with a defective screen, after changing the screen I found this surprise, so I don't know how and when it appeared. Thanks for the answers and advice

But a new problem appeared Forwarder did not work for a month because I sent the joystick for repair. after a month appeared a problem with hydrostatic system. starts to drive unevenly, with small jumps (it doesn't matter what speed or gear it is, it's always the same) It doesn't have the strength to drive at full speed. I tried disconnecting all the brakes, the problem remained the same. Joysticks and other hydraulics work well. There was no such thing before, it worked perfectly. I think some kind of hydro electromagnet is stuck. Not much chance, but maybe someone has had this happen and could you tell me where to start looking? Because a lot of wires really don't want to take everything apart. broke while standing

This was fixed with running E-gas procedure, and was caused from a mis-match between throttle pedal and engine speed. Maybe new electronic component is detected as a failure? OH
