The controller has a backup system for operator dry operation. When there is a problem with the electronic control system, the operator can activate the backup system to control the size of the main spring and the engine throttle. The backup system consists of a backup device for the governor that controls the engine speed and a backup device for the main pump. When there is a problem with the electronic control system that controls the governor, the operator can activate the governor backup device, and when there is a problem with the electronic control system that controls the main pump, the operator can activate the main pump backup device.
