Technical data Operating sequence

When the blower is started from the rest position the electric motor rotates the lance through the reduction gear and the drive gear. This movement opens the valve by means of a cam. The lance rotates until the design blowing arc is completed. The valve is closed by reversing mechanism back to its rest position. The rotation of the lance continues up to get its rest position.
