A. Main tank.
B. Tank level indicator.
C. Main tank lid.
D. Footboard/SafetyLocker (optional).
E. Rinsing tanks (optional).
F. Clean water tank (optional).
G. TurboFiller (optional).
Roadworthiness
When driving on public roads and other areas where the highway code applies, or areas with special rules and regulations
for marking and lights on implements, you should observe these and equip implements accordingly.
Sprayer use
The HARDI sprayer is for the application of crop protection chemicals and liquid fertilisers. The equipment must only be used
for this purpose. It is not allowed to use the sprayer for any other purposes. If no local law demands that the operator must
be certified to use spray equipment, it is strongly recommended to be trained in correct plant protection and in safe
handling of plant protection chemicals to avoid unnecessary risk for persons and the environment when doing your spray
job.
Frame
Very strong and compact frame which also has a strong chemical and weather resistant electrostatic lacquer coat. Screws,
nuts, etc. have been DELTA-MAGNI treated to be resistant to corrosion.
Tanks and equipment
The main tank made of impact-proof, UV-resistant and chemical resistant polyethylene, has a purposeful design with no
sharp corners for easy cleaning.
Nominal contents 800, 1000, 1200, 1500 or 1800 litres.

Liquid system
Pump
Diaphragm pump with 3 diaphragms, model 1303 or diaphragm pump with 6 diaphragms, model 363 or 463. Standard =
540 r.p.m. (6 splines shaft). Optional = 1000 r.p.m. (21 splines shaft). The design of the diaphragm pump is simple, with easily
accessible diaphragms and valves which ensures liquid does not contact the vital parts of the pump.
Valves and symbols
The valves of the valve system are distinguished by coloured
identification on the function labels. Symbols corresponding to every
possible function of use are located on the discs for easy identification
and operation. The modular MANIFOLD system facilitates the addition
of optional extras on both pressure side and suction side. Furthermore
the suction manifold can be fitted with a return valve which ensures
better draining of the sprayer before cleaning. A function is activated by
turning the handle towards the desired function. The valves are:
A. Agitation valve (optional equipment)
B. Pressure valve
C. Return valve
D. Suction valve
E. External filling device valve (optional equipment)
(D) Suction valve
This valve selects suction from main tank (for spraying) or rinsing tank.
Turn the handle so the indicator points towards the label of the required
function. If the handle is turned to vertical position (indicator not
pointing to a label), the valve is closed.
(B) Pressure valve
This valve selects where to direct pressurized liquid.
The active function is indicated by the indicator. Turn the handle so that the indicator points to the label of the required
function. If the handle is turned to a label-free position (unused function), the valve is closed.
(C) Return valve
With this valve you select whether return liquid should be directed back to the main tank or to the pump. Normally the liquid
is directed to the tank return. When the tank is nearly empty, the handle is turned so the liquid is directed to the suction side
of the pump in order to fully emptying the tank prior to cleaning.
(A) Agitation valve (optional)
With the Agitation valve you can select between agitation in the tank or tank cleaning with the rinsing nozzle.

(E) External Filling Device valve (optional)
The valve is used when filling from an external tank or reservoir.
Activating valve starts/stops the filling process. Note that the suction valve must be closed for maximum filling capacity.
μATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see
the section ‘Maintenance’ for further information.
Control unit
The sprayer is equipped with either a BK control unit or an EVC control unit.
The system is based on EVC - Electrical Valve Control. The ON/OFF is linked to the section valves, which is results in a very
quick response to ON/OFF. The operating unit is constructed of modules and is electrically controlled via a remote control
box.
With HARDI-MATIC that ensures a constant liquid volume per hectare (l/ha) at varying forward speed within the same gear
when the number of P.T.O. revolutions are between 300-600 r/min.
BK control unit
The BK control unit consists of; pressure agitator valve, safety valve, main ON/OFF valve, pressure filter with pressure gauge,
distribution valves with pressure equalization and HARDI-MATIC pressure control valve.
EVC control unit
EVC - Electrical Valve Control. The ON/OFF is linked to the section valves, which results in a very quick response to ON/OFF.
The operating unit is of modular design and is electrically controlled via a remote control box. The unit has a built-in HARDI
MATIC.
Clean water tank (optional)
The water in this tank is for hand washing, cleaning of clogged nozzles
etc. Only fill this tank with clean water from the well.
The clean water tank is placed on the sprayer’s left side, right behind the
MANIFOLD valves.
Capacity: approx. 15 litres (3.3 Imp. gal).
±WARNING! Although the clean water tank is only filled with clean
water, this water must NOT be used for drinking.
Suction from external tank

3 - Description
17
Filters
A suction filter is fitted at the top of the tank and is indicated with red
hose tail.
In-line pressure filters can be fitted at each boom section as an option
(J).
Nozzle filters are fitted at each nozzle.
All filters should always be in use and their function checked regularly.
Pay attention to the correct combination of filter and mesh size (see
“Spray Technique” book).
Self-cleaning filter
With the self-cleaning filter the impurities that exist in the spray liquid
will by-pass the filter and be recirculated back to the tank via the return
flow.

8. Ball valve
Ball valve (8) should normally be open, but may be closed in situations
where return flow is to be avoided, i.e. by flushing of spray lines without diluting the spray liquid in the main tank.
μATTENTION! If the ball valve is closed, the self-cleaning function is inoperative!

3 - Description
18
TurboFiller (optional)
TurboFiller suction valve
The valve is used simultaneously with the TurboFiller. The valve has 2
settings: Continuously open or spring loaded normally closed. Open the
valve when chemicals are to be filled into the TurboFiller.
TurboDeflector valve
This TurboDeflector valve activates the Vortex flushing of the TurboFiller.
Lift the lever to lock it in open position for continuous liquid rotation in
the hopper.
Chemical Container Rinsing lever
The upper lever is used for two purposes:
When the TurboFiller lid is open: For rinsing empty containers. Place the
container over the rotating flushing nozzle in the middle of the
TurboFiller to rinse the inside of the container.
When the TurboFiller lid is closed: Use the Chemical Container Rinsing
lever to rinse the hopper when the filling of chemicals is completed.
€DANGER! Do not press the lever unless the multi-hole nozzle is covered by a container as spray liquid may otherwise
hit the operator.
