I have recently purchased a used knight trailed sprayer, the sprayer came with limited manuals and i was just wondering if anyone could give me more information about the two guages on the front. I beleive the left hand one is water pressure and the right is air pressure? is this for the pressure regulator system for altering speed but rate remaining constant? it also has a fiiting like on a tyre inner tube to attach to a compressor. the sprayer came with a delta 3 computer so not sure if this guage is needed?
Any info would be appreciated
