Hi.
I think this forklift has a 2 coil brake device. 1 coil for releasing brake and afterwards 1 coil to hold it released. Sometimes the driver for hold-coil is faulty/burned. Or you have an error on power-steering. Error on power-steering keeps forklift from running and the brake is on for safety reasons. I'm back on monday and I'll look in SH for further info.
Regards, Max
