Assembling the remote deflector and remote 3rd hole unit on my new lesco spreader was a bit tricky. It seems that the offset bracket has to be flipped around to face inward instead of outward as it shows in the diagram. It would have been much easier with better diagrams and pictures. When you push the dual remote handles both down to the on position should this drop the deflector and close the third hole? So, when the third hole lever is in the on position, this really means the hole is closed?
