The D.A.H. system requires a double acting hydraulic
outlet. The hydraulic hoses are marked with arrows to
indicate direction of oil flow.
The D.A.H. system requires an oil flow between 10 and
90 l/min (19.8 Imp. gal/min.) and a min. pressure of 130
bar (1886 psi.). The system has a built-in flow regulator
that 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 CENTRE
tractor hydraulics, depending on tractor model.
1. Unlocked = Open centre hydraulics (Constant Flow)
2. Locked = Constant Pressure (Closed Centre) and
Load-Sensing hydraulics
If you doubt which type of hydraulic system your tractor
is equipped, ask your tractor dealer.
WARNING!
Hydraulic leaks: Never use your
fingers to locate a leakage in any part of the
hydraulic system. Due to high pressure, hydraulic
oil may penetrate the skin.

12V power sockets are required for the control boxes.
Note polarity!

The control boxes for EC
operating unit and D.A.H.
are to be fitted in the tractor
cabin at a convenient place.
Tapping screws can be
used for mounting.
The wires must have a cross-sectional area of at least
4.0 mm2 (#10 awg) to ensure sufficient power supply.
The boxes must be fused according to the table.
Use the HARDI Electric distribution box (No. 817925) if
the tractor has a doubtful power supply.
