Hydraulic system
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 to
90 l/min and a min. pressure of 130 bar. 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 tractor hydraulics.
Hydraulic pump transmission
Before initial start fill the hydraulic oil tank with the 70 l
of hydraulic oil, type "SHELL TELLUS T46", enclosed in
containers.
Connecting the hydraulic pump
Connect the hydraulic pump with the P.T.O. shaft of the
tractor. Make sure that the pump "locks" correctly. Fix
the pump in such a way that the profile fitted on the
right side is located on the right side of the coupling
device preventing the pump from rotation.
The hydraulic pump gear has already been filled with 0.7
l (25 imp.fl.oz) oil. However, check level before initial
start and never omit the regular service intervals.
Oil cooler (if fitted)
If the sprayer is operating in ambient temperatures
above 30°C (112°F) an oil cooler kit must be fitted in
order to keep transmission oil temperature at the speci-
fied level. The thermostat will engage the electric fan
when the oil temperature reaches appr. 50°C (148°F)
and disengage at appr. 40°C (130°F).
Connect the fan electric plug to a 12 V socket.
Control boxes and power supply
Two power boxes of 12V are required. Note polarity!
For EC: Brown pos. (+), blue neg. (-)
For D.A.H.: White pos. (+), black neg. (-).
The control boxes for EC-operating unit
and for D.A.H. are fitted in the tractor
cabin at a convenient
place. See section on
assembly for initial
mounting.
The wires must have a
cross-sectional area of
at least 4.0 mm to
ensure sufficient power
supply. For the EC-
operating unit the tractor
circuit should have an 8
Amp fuse and for the
D.A.H. a 16 Amp fuse.

Roadworthyness
When driving on public roads and other areas
where the highway code applies, or areas
where there are special rules and regulations for mark-
ing and lights on implements, you should observe these
and equip implements accordingly.
Before taking the sprayer into operation
Although the sprayer has been applied with a strong
and protective surface treatment on steel parts, bolts
etc. in the factories it is recommended to apply a film of
anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL
ENSIS FLUID) on all metal parts in order to avoid
chemicals and fertillizers to discolorate the enamel.
If this is done already before the sprayer is put into
operation the first time, it will always be easy to clean
the sprayer and keep the enamel shiny for many years.
This treatment should be carried out every time the oil
film is washed off.
Operating instructions
Filling of water
Water can be filled into the main tank in fol-
lowing ways:
1. Filled through tank lid.
2. Filled by diaphragm pump through suction side fitted
filling device (optional extra) by normal pump capac-
ity directly to the tank.
3. Filled by diaphragm pump through pressure side
fitted injector/venturi type Fast Filling Device (op-
tional extra) by up to 3 times normal pump capacity.
4. Combination of 2 and 3.
The tank should normally be filled
adding the chemicals - always read instruction at
chemical container!
NOTE! Max. permitted tank content is 2000 kg
(4410 lb) corresponding to 2000 litres (440
imp.gal.) water or appr. 1550 litres (340
imp.gal.) of liquid fertilizers.
Filling through tank lid
Remove tank lid and fill water through strainer to pre-
vent rust or other particles to enter the tank.
It is recommended to use as clean water as possible for
spraying purposes.
WARNING: Do not let the filling hose enter the
tank. Keep it outside the tank, pointing towards
the filling hole. If the hose is lead into the tank
and the water pressure drops at the water sup-
ply plant, chemicals may be
syphoned back and con-
taminate the water supply
lines, plant and well.
