rVerify that fill and demand sensors are set at the correct height and adjusted proper- ly. Refer to manuals sup- plied with the fill or demand signaling device.
If a compressed air line is not connected to vacuum or material valves, the valves cannot open to allow the pump to draw material into the receiver.
