Roadworthiness
When driving on public roads and in other areas, where the highway code applies, or in 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 fertilizers. 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 prevent unnecessary risk for persons and the environment, when carrying out
your spray job.
Frame
Very strong and compact steel frame with a strong chemically resistant and weatherproof electrostatic lacquer coat. Screws
and bolts etc. have been Delta/Magni treated to be resistant to corrosion.
Identification Plates
CE identification plate fitted on the frame indicates producer name,
identification no., make, model, type, production year, tank capacity and
tare mass for the sprayer.
This plate is located on the front side of the sprayer.
Ta nk s
The tanks are made of impact-proof polyethylene, resistant to UV radiation and chemicals. The main tank has a purposeful
design with no sharp corners for easy cleaning. The filling hole is placed so it can be accessed from the platform. This ensures
an easy access for the filling of sprays, cleaning of the tank etc. The sprayer may also be equipped with two rinsing tanks and
a clean water tank.
Nominal tank contents are 1200, 1500 or 1800 litres.

Liquid system
Pump
Diaphragm pump with 3 diaphragms, model 1303 or diaphragm pump
with 6 diaphragms, model 363 or 364 or 464.
Standard = 540 rpm (6 splines shaft). The design of the diaphragm pump
is simple, with easily accessible diaphragms and valves, which ensure
that liquid does not contact the vital parts of the pump.
Pump model 363 is shown on the picture.
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. If the handle is turned to a label-free position (unused
function), the valve is closed. The valves are:
A. Agitation Valve
B. Pressure Valve
C. Suction Valve
D. External Filling Valve (optional equipment)
A - Pressure valve
With this valve you can select where to direct pressurized liquid.
B - Agitation valve
With this valve you can select between agitation in the tank or tank cleaning using the rinsing nozzle.

C - Suction valve
With this valve you can select suction from main tank (for spraying) or from rinsing tank.
D - External Filling Device valve (optional)
This valve is used, when filling from an external tank or reservoir.
Activating the valve starts/stops the filling process. Note that the suction valve must be closed for maximum filling capacity.
μ
ATTENTION! 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 an EVC control unit.
EVC Control Unit
The system is based on EVC - Electrical Valve Control. The ON/OFF is
linked to the section valves (one valve for each spray boom section),
which results in a quick response to ON/OFF. The operating unit is of
modular design, and it is electrically controlled by a remote control box.
The section valves are fitted with a constant pressure device and a
pressure drop line.
These features allows the operator to shut off individual boom sections.
The unit has a built-in HARDI-MATIC system. This system ensures a
constant liquid volume per hectare (l/ha) when driving forward at
varying speed within the same gear, as long as the number of PTO
revolutions are kept between 300-600 rpm.

Clean Water Tank
The water in this tank is for hand washing, for 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: approximately 15 litres.
±
WARNING! Although the clean water tank is only filled with clean
water, this water must NOT be used for drinking.
Filters
A suction filter is fitted at the top of the tank. It is indicated with a red
hose tail.In-line pressure filters can be fitted at each boom section as an
option(J). However, it is standard equipment on this sprayer.
Nozzle filters are fitted at each nozzle.
All filters should always be in use and their function should be checked
regularly. Pay attention to the correct combination of filter and mesh
size. For more, see “Technical Specifications” in this book.
Self-Cleaning Filter
With the self-cleaning filter, the impurities that exist in the spray liquid
will be filtered out and returned to the tank via the return flow.

BoomPrime
BoomPrime is a low pressure circulation system, which primes the spray boom tubes prior to spraying, ensuring a
homogenous fluid in the boom tubes and in the main tank. Below the illustration shows the BoomPrime system for the
boom. Components are explained in the diagrams for the liquid systems.
•
The BoomPrime system is attached to each end of a boom section (A).
• The boom spray sections are fed into the middle of each section (B).
Liquid for BoomPrime is taken through a bypass valve (D) just before the flowmeter. This valve operates in opposite phase:
When priming, the direction of liquid flow will be reversed. The liquid will be fed into the nozzle tubes from each end, and
they will then return any water back to the main tank through the EFC section valves return line (C).
The BoomPrime pressure is adjusted by the handle on the control valve (E), which comprises a pressure gauge.
For adjustment, see the section “BoomPrime Adjustment”.

Dilution Kit (optional)
The dilution kit is a built-in system consisting of the two valves (no. 25 and 26 below) added to the liquid system, enabling
the liquid to be redirected from the rinsing tanks into the main tank and piping to dilute the spray liquid residues.
The dilution kit will ease diluting of chemicals in main tank or boom piping done from the drivers seat, while driving in the
field. This can be useful when interrupting a spray job, e.g. because of rain or before the tank has to be refilled at the farm.
The dilution kit has two functions which are selected from the optional function switch on the Spray Box in the tractor.
• Tank dilution: Dilute boom piping and the main tank at the same time.
• Boom dilution: Dilute the boom piping only.
÷
NOTE! The dilution kit is NOT a rinsing device. For rinsing the sprayer, please see the section “Cleaning” in this book.

NO TE! Dilu tion of che mical resi dues m ay be req uire d by la w in c er tai n situ atio ns bef ore ret urning to th e farm f or f illin g
or cleaning. Please familiarize with applicable rules and follow these.
Dilution kit label
As the Dilution kit uses the optional function switch on the Spray Box, a
label (HARDI item no. 97617800) has to be fitted before use. The label is
to easily recognize, which function of the Dilution kit is to be selected.
Place the label around the switch used for optional functions, as shown
on the picture.

Spray Boom
Boom and Terminology
The sprayer is fitted with a VPZ boom. The boom is supported by a trapeze fitted to the tank frame.
The trapeze helps the boom to stay horizontal when unfolded, and it protects the boom against vibrations and shocks, when
driving on uneven ground. This ensures longer boom life and improves boom stability for better spray distribution.
Booms are available in 20, 21, 24, 27 and 28 m working width. All booms are provided with spring loaded breakaway.
For 3-folded booms, the terminology is as follows:
A - Centre section
C - Middle section
D - Outer section
E - Breakaway section

Equipment
Nozzle Pressure Gauge
The remote pressure gauge is integrated at the front of the sprayer. This
gauge measures the working pressure in the boom tubes as close to the
nozzles as possible.
The outputs stated in the nozzle charts are always based on the pressure
measured at the nozzle. Both when calibrating and spraying, the
pressure must be adjusted according to the readings of this pressure
gauge.
Footboard
The footboard gives access to the main tank lid. It ensures easy access
for filling of sprays, cleaning of tank, etc.
Safety Locker
The safety locker is for storage of safety gear such as non-contaminated
protective gear, soap for hand washing etc. The locker is split in two
compartments for the separation of clean clothes and contaminated
equipment.
±
WARNING! Although this locker is meant for the storing of noncontaminated items, it must never be used for the storing of food,
beverage or other items meant for human consumption.

Canister for Pesticide Information
This canister is for storing information about the present pesticide
product in the tank - such as labels, instructions and safety data sheet
(SDS) from the pesticide supplier.
The canister is placed on the side of the footboard.
Unscrew the lid and store this information inside the canister at all times
when using the sprayer.
μ
ATTENTION! Although this canister is meant for the storing of
non-contaminated items, it must never be used for the storing of
food, beverage or other items meant for human consumption.
Tank Level Indicator
The actual tank level in the main tank can be observed on the tank level
indicator. The scale is displayed in litres (or Imp. gal/US gal. for certain
countries).
External Cleaning Device (optional)
This equipment comprises a hose reel for cleaning the complete sprayer
externally in the field with clean water. The External Cleaning Device is
located on the boom centre section at the back.
±
WARNING! The cleaning device produces a high water pressure.
Incorrect use may result in injuries!
€
DANGER! Never work in bare feet or sandals. It is recommended
to wear goggles during the cleaning work. It is recommended
that the user, or anyone near the cleaning place, protects himself
against particles bouncing up during the cleaning.
