The hydraulic hoses are marked with arrows toindicate direction of oil flow.The D.A.H. system requires an oil flow between 10 and90 l/min (19.8 Imp. gal/min.) and a min. pressure of 130bar (1886 psi.). The system has a built-in flow regulatorthat maintains constant speed on hydraulic movements.Before operating the hydraulics, the clip at the distribu-tion valve (situated under the platform behind the pump)should be set for OPEN CENTRE or CLOSED CENTREtractor hydraulics, depending on tractor model.1. Unlocked = Open centre hydraulics (Constant Flow)2. Locked = Constant Pressure (Closed Centre) andLoad-Sensing hydraulicsIf you doubt which type of hydraulic system your tractoris equipped, ask your tractor dealer.WARNING! Hydraulic leaks: Never use yourfingers to locate a leakage in any part of thehydraulic system. Due to high pressure, hydraulicoil may penetrate the skin.ContrContrContrContrControl bool bool bool bool boxxxxxes and powes and powes and powes and powes and power supplyer supplyer supplyer supplyer supply12V power sockets are required for the control boxes.Note polarity!For EC: Brown pos.
