4 - Sprayer setup4.3HZ hydraulic blockThe hydraulic flow can be adjusted on the HZ hydraulic block ifnecessary. First set the hydraulic flow on the tractor so the boom raisesand lowers at the desired speed. Then check the speed of the fold andtilt functions. If adjustment is necessary, loosen jam nut (A) and turnthrottle valve (B) all the way in using an allen wrench. Then turn throttlevalve (B) back out 1-1/2 turns. If the fold and tilt functions are too slow,turn throttle valve (B) out more. If the fold and tilt functions are too fast,turn throttle valve (B) in more. Tighten jam nut (A) when the desiredspeed is reached.Open center hydraulics (trailed - optional equipment)The open center hydraulic block is needed if the tractor uses opencenter hydraulics and/or if load sensing will be used.The valve (1) on the side of the block is factory set for open centerhydraulics, but if closed center hydraulics will be used (also incombination with load sensing) then screw in the valve.Certain tractor models are able to use Load Sensing without connectingan external sensing line. But if optimal sensing control pressure cannotbe obtained, an external sensing line needs to be mounted (3). Pleaseconsult your tractor dealer for correct setup and correct connection.Before operating the hydraulics, the valve should be adjusted accordingto the specific tractor model. If you have doubt about which type ofhydraulic system your tractor is equipped with, please consult yourtractor dealer.List of setting combinations for flow element and circuit value:Valve no. 1 2 3 (LS port)Open center out out Not conn.Closed center in in Not conn.Load sensing (LS) in out* Connected*if tractor requires pressure relief.± WARNING! Always be sure to fully extract or retract the open/closed center selection valve (1). Failure to do so canresult in damages to vital pump parts.± WARNING! It is of essential importance that connectors on sensing line are kept totally clean. Failure to do so canresult in impurities entering the pump and thereby cause damages to vital pump parts.A B
