Frame
Strong and compact frame with several options of
drawbars and wheel sizes. The frame has a strong
chemical and weather resistant electrostatic lacquer
coat. Screws, nuts, etc. have been DELTA-MAGNI
treated to be resistant to corrosion.
Tank
UV-resistant Polyethylene in a suitable design with no
sharp corners for easy agitation, emptying and cleaning.
Nominal contents 2200, 2800, 3200 or 4200 l.
Pump
Diaphragm pump with 6 diaphragms, model 363 or 463,
depending on boom width, with easily accessible valves
and diaphragms. Standard = 540 r.p.m. (6 splines)
Optional = 1000 r.p.m. (21 splines).
MANIFOLD SYSTEM
All functions of the spray circuits are operated via the
centrally situated MANIFOLD valves with colour coded
plates and pictorial symbols for easy operation.
Operating unit
The system is based on EVC - Electrical Valve Control.
The on/off is linked to the section valves, which is
resulting in a very quick response to on/off.
and 28 m working width.
Identification plates
An identification plate fitted on the frame indicates
producer name, model, own weight, max. weight, max.
pressure of the hydraulic system, and max. pressure of
the spray liquid system. Frame, boom centre frame, and
inner/outer sections also have identification plates
indicating boom type and part number of spare parts. If
ordering spare parts, inform your dealer of these, so the
right model and version are described.
T271-0010x
The operating unit is constructed of modules and is
electrically controlled via a remote control box.
The built-in HARDI-MATIC ensures a constant volume
per hectare of the liquid (l/ha) at varying forward speed
within the same gear when the number of P.T.O. revolutions are between 300-600 r.p.m. (pump 540 r.p.m) or
650-1100 r.p.m. (pump 1000 r.p.m.).
Filters
With the self-cleaning filter the impurities that exist in the
spray liquid will bypass the filter and be recirculated back
to the tank via the return flow. Also suction filter and
nozzle filters are standard. In-line pressure filters can be
fitted as option.
Boom
All booms are suspended in a strong, stable parallelogram boom lift.
The HAY/HAZ booms are trapeze/pendulum suspended
and fully hydraulically operated, including boom slanting
control and air slot angling. HAZ models have Direct
Acting Hydraulics (D.A.H.) and individual boom tilt
function as well.

The HARDI COMMANDER sprayer is for the application
of crop protection chemicals and liquid fertilisers.
The equipment must only be used for this purpose. It is
not allowable to use the sprayer for other purposes.
If no local law demands that the operator must be
certified to use the 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 the spray job.

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
anticorrosion oil (e.g. CASTROL RUSTILLO or SHELL
ENSIS FLUID) on all metal parts in order to avoid
chemicals and fertilisers discolouring the enamel.
If this is done before the sprayer is put into operation for
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
protection film is washed off.

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 p.s.i.) The system has a built-in flow regulator
that maintains constant speed on hydraulic movements.
The hydraulic distribution block is situated underneath
the platform floor.
The valves on the block are operated by means of
manual override and each valve can be regulated to be
open or closed.

IMPORTANT! The load apportioning
valve must be set at the position
corresponding to the load on the
trailer, for obtaining optimal air pressure to the trailer brakes.
= Relieved= Half full tank
= Empty tank= Full tank
WARNING! Driving with wrong load apportioning
valve setting, will make the brakes under- or overapply, which can cause hazardous situations.
NOTE! If the air hose(s) are disconnected with air in the
brake air tank, control pressure
will be dumped and the brakes
will engage fully. If the sprayer
must be moved with air in the
tank and without the air hose(s)
connected to the tractor, the load
apportioning valve must be set
at relieved to disengage the
brakes. Remember to reset the
handle to brake position again
afterwards. When parking the
sprayer, always engage the parking brake, as the air
brakes will only be engaged as long as there is air in the
tank! Cover the couplings with the dust flaps when
hoses are disconnected.

A trailer with articulating drawbar (TRACKER) behaves
differently than a normal trailer.
In tracking position the vehicle centre of gravity is
displaced further more compared to the vehicle centre
line of a normal trailer.
Compared to a conventional trailer a TRACKER has
decreased stability when turning, especially when turning
on hillsides.
To avoid overbalancing, pay attention to these guidelines:
1. Avoid sudden, tight turns
2. Slow down before entering a curve or turning, and
drive with a constant, low speed during the turn.
3. Never slow down too fast, never brake heavily and
never stop suddenly in a curve, or when turning on a
hillside, when the sprayer is articulated.
4. Be careful when turning on uneven ground
5. Set the track gauge as wide as possible
6. The proper function of the hydraulic damping is
essential to obtain good stability
7. Keep stabiliser chains on the tractors liftarms tight
8. For safety reasons, the following limitations are set for
TRACKERS (with unfolded booms):

The boom is equipped with two support wheels. When
spraying with low boom heights on bare ground or plants
in the first growth stage it is recommended to fold down
the support wheels. In later growth stages the wheels
should remain folded up.
IMPORTANT! When driving on public roads the support
wheels should be folded up and secured in order to keep
the machine overall width according to the regulations!
The boom suspension will normally suit most conditions
and do not require any adjustment. The suspension will
keep the boom parallel to the ground and compensate
for uneven ground.
However, special conditions or situations can require the
suspension to react less or more slowly.
When the RH and LH
guide rods are
parallel to each
other (factory
setting) the boom
suspension will
react immediately,
and the boom will
move independently of the
trailer or tractor.
If the boom
should follow the movements or inclinations of the trailer
the guide rods should be inclined towards each other at
the rear.

*Agitation
Normally, Agitation should be on but please refer to the
following rules of thumb:
1. Choose Without Agitation if a high level of
effervescence occurs in order to reduce the
amount of foam.
2. Choose Agitation when using powder
chemicals in order to avoid sedimentation.
3. Close the valve if spraying with a high
volume and it is impossible to achieve
sufficient pressure.

In order to close one or more sections of the boom,
switch the relevant distribution valve V to off position.
The pressure equalisation ensures that the pressure
does not rise in the sections which are to remain open.
When the sprayer is put aside, the control box and the

The remote pressure gauge is integrated in the front
locker. This gauge measures the working pressure in the
boom tubes as close to the nozzles as possible. This
pressure reading will always be slightly lower than the
reading at the operating unit pressure gauge.
The outputs stated in the nozzle charts are always based
on the pressure measured at the nozzle.
Always adjust pressure when calibrating and spraying
according to readings at the Remote pressure gauge.

IMPORTANT! The yellow MANIFOLD valve should
normally be open, but must be closed in the following
cases:
1. If rinsing with water from the rinsing tank and a
quantity of spray liquid still remains in the main tank
(otherwise the spray liquid will be diluted).
2. If opening the self-cleaning filter and a quantity of
spray liquid still remains in the main tank (otherwise
there is a risk that spray liquid will flow out).
Choice of correct restrictor
It is important to have a large flow through the filter. This
is achieved by choosing the restrictor size in relation to
the liquid consumption of the spray boom.
4 restrictors are supplied. Use the green one (largest
orifice) first.
GB 08 04
37
Operation
The hose N is demounted at the
self-cleaning filter, the restrictor
is put in the hose and the hose
is mounted again. If the required working pressure cannot
be obtained, the restrictor is too
large. Choose a smaller restrictor. Start
with a black one, then a white and finally a
red one.
When cleaning the filter remove hose N
and the hose at the safety valve, and
check there are no residue.
Standard filter size is 80 mesh. Sizes of
50 and 100 mesh are available and can
be changed by opening the filter top,
and replace the strainer.
Check the O-rings before reassembling the filter and
replace if damaged.

With TWIN air assistance energy is added to the spray
droplets to improve control with the spray liquid .
This way TWIN makes it possible to:
carry the spray droplets safely to the target and in-
crease plant deposit
minimize off-target deposit due to wind drift or loss on
the ground
open the crop and obtain good penetration even with a
low volume rate
ensure a high coverage.

The main purpose of the TWIN angling system is to
counteract for the negative influence which wind direction and driving speed have on the quality of the spray
job. Further the co-angling af air and liquid can help
opening dense crops for better penetration
The TWIN FORCE air system can be set at any angle
from 40° forward to 30° back (defined by the air stream).

The air speed and angling must always be adjusted
individually for each spray job and the given weather
conditions.
It is always a good idea to get used to a new sprayer out
in a field with only water in the tank, on this occasion the
following routine for air adjustment should be practised:
018
1.Start with the air vertical
2.Set the air speed ............... A
3.Find the best angling ......... B
4.Readjust the air ..................A
IMPORTANT! Fine turning of air speed and angling will
often be necessary all through the spraying job.
T030-0002
It is easiest to find the best air setting to reduce drift
when the sun is low and behind the boom (backlight).
These conditions make the drift more visible.
GB 09 01
43
Air Technique
A Setting of air speed, rules of thumb
Step 1: Find the range of air speeds that can control
drift:
1.Start with the air setting at zero and keep increasing
the air speed just to the point where you can see that
the drift cloud is minimised - note minimum setting.
2.Then increase the air speed until you see drift again note maximum setting.
3.Now you know the range of air speeds that can be
used with minimum drift.
Bare ground / low crop
The range of air speeds is usually very small.
Taller crop
The taller the crop the wider the range of air speeds that
can reduce drift.
At higher wind speeds
More air is needed on the sprayer and it is advisable
to drive more slowly and use minimum boom height
(40 cm)/(16 in).
NOTE! Too high air speed over bare ground/low crop
can cause reflection of the spray liquid and leave dust
on the leaves, which can again reduce the effect of the
plant protection product.
Step 2: Set the optimal air speed within possible the
range mentions above.
ConditionsAir speed recommendations
Bare ground / low crop:Use maximum air within the
possible range
Taller crop:Deeper crop penetration
requires more air on the
sprayer (if you are in doubt
check with water sensitive
paper).
Forward speed:Higher forward speeds require
more air on the sprayer.
Volume rate:Lower volume rates require
more air assistance to avard
drift.
B Angling of air and liquid, rules of thumb
To control wind drift the influence of wind speed and
wind direction as well as the horizontal air current
around the boom due to forward speed must be minimised. Because it is a sum of two forces with variable
direction and size that we have to counteract for, the
following can only be very rough guidelines.
NOTE! Often it will be necessary to drive with two
different anglings, so the angling is changed when
changing driving direction after turning at the headland.
Wind directionAngle / air speed
Head wind:Angle forward
Down wind:Angle back (if the forward speed is
higher than the wind speed: angle
forward)
Side wind /
No wind:Angle vertical or back. Only high
forward speeds may require forward
angling.
Crop conditionAngle / air speed
Bare ground/
low vegetation:Low air speed and angling back will
often be the best setting to avoid
reflection of spray liquid.
Dense crop:The angling feature is ideal to
help opening the canopy and im
prove penetration. If you follow the
crop movement as you are varying
the angling you will find that at certain
settings the crop will open more for
penetration.
If wind speed, wind direction or for some reason forward
speed changes during spraying the optimum angling is
likely to change too. Be aware that with certain combinations of air speed and angling you can close or flatten
the crop and make penetration impossible - follow the
crop movement intensively especially when setting the
air assistance and keep an eye on the crop all through
the application.
NOTE!
It is most important that the sprayer operator is familiar
with the above rules of thumb before using the TWIN
sprayer
All volume rates, pressures and air adjustments stated
in the following tables are, of course, guiding. Special
conditions regarding climate, crop quality, spraying time
and applied chemical can change the procedure. The
tables are showing practice in northern Europe, and
conditions may be very different in other countries. If you
want some local advice you are very welcome to contact
the TWIN application expert at the HARDI importer or
daughter company in your country
The volume rate can generally be reduced to half of
what is applied with a conventional sprayer, but with a
minimum of 50-60 l/ha at 7-8 km/h (5.5-6.5 GPA at 4.5-5

Air Technique
mph. Exceptions are of course liquid fertiliser and
herbicides whose selectivity is based large droplets that
will only stick to the weeds
Low drift nozzles can also be fitted on a TWIN sprayer
and help reduce drift even further
If there is a detailed spraying instruction on the chemical label regarding drop size, spray pressure, spray
volume rate etc. this should be followed. Enclose 1 bag
of water sensitive paper and instruction of how to use
with all TWIN sprayers.

USE WATER SENSITIVE PAPER TO HELP FIND THE
BEST AIR SETTING.
Some time spent in different types of crops with clean
water in the tank and some water sensitive paper will be
valuable experience for the future work with your TWIN
sprayer. The paper can be cut into smaller pieces (to
simulate the target) and fixed with double sided tape at
relevant places in the crop. Then spray with pure water
and check the blue spots (droplets) on the paper. This
way you can test different spraying techniques. Water
sensitive paper is available at your local HARDI dealer,
part No. 893211
NOTE! All volume rates, pressures and air suggestions indicated in these tables are only guiding. Special conditions regarding climate, quality
of the crop, spraying time and chemicals applied (burning) may partially change the procedure.
* NOTE! If dust is deposited on leaves the air speed must be reduced.

In order to derive full benefit from the sprayer for many
years the following service and maintenance program
should be followed.
IMPORTANT! Always read the individual paragraphs.
Read instructions for service/maintenance jobs carefully
before starting on the job. If any portion remains unclear
or requires facilities which are not available, then for
safety reasons please leave the job to your HARDI
dealers workshop.

Guidelines
1. Read the whole chemical label. Take note of any
particular instructions regarding recommended
protective clothing, deactivating agents, etc. Read the
detergent and deactivating agent labels. If cleaning
procedures are given, follow them closely.
2. Be familiar with local legislation regarding disposal of
pesticides washings, mandatory decontamination
methods, etc. Contact the appropriate department,
e.g. Dept. of Agriculture.
3. Pesticide washings can usually be sprayed out on a
soakaway. This is an area of ground that is not used
for cropping. You must avoid seepage or runoff of
residue into streams, water courses, ditches, wells,
springs, etc. The washings from the cleaning area
must not enter sewers. Drainage must lead to an
approved soakaway.
4. Cleaning starts with the calibration, as a well calibrated sprayer will ensure the minimal amount of
remaining spray liquid.

Cleaning the tank
1. Dilute remaining spray liquid in the tank with at least
10 parts of water and spray the liquid out in the field
you have just sprayed - See paragraph Use of rinsing
tank and rinsing nozzles.
NOTE: It is advisable to increase the forward speed
(double if possible) and reduce the pressure to 1.5
bar (20 psi).
2. Select and use the appropriate protective clothing.
Select detergent suitable for cleaning and suitable
deactivating agents if necessary.
3. Rinse and clean sprayer and tractor externally. Use
detergent if necessary.
4. Remove tank and suction filters and clean. Be careful
not to damage the mesh. Replace suction filter top.
Replace filters when the sprayer is completely clean.
5. With the pump running, rinse the inside of the tank.
Remember the tank roof. Rinse and operate all
components and any equipment that has been in
contact with the chemical.
Before opening the distribution valves and spraying
the liquid out, decide whether this should be done in
the field again or on the soakaway.
6. After spraying the liquid out, stop the pump and fill at

1
least
/5 of the tank with clean water. Note that some
chemicals require the tank to be completely filled.
Add appropriate detergent and/or deactivating agent,
e.g. washing soda or Triple ammonia.
5. It is good practice to clean the sprayer immediately
after use and thereby rendering the sprayer safe and
ready for the next pesticide application. This also
prolongs the life of the components.
6. It is sometimes necessary to leave spray liquid in the
tank for short periods, e.g. overnight, or until the
weather becomes suitable for spraying again. Unauthorised persons and animals must not have access
to the sprayer under these circumstances.
7. If the product applied is corrosive, it is recommended
to coat all metal parts of the sprayer before and after
use with a suitable rust inhibitor.
Remember:
Clean sprayers are safe sprayers.
Clean sprayers are ready for action.
Clean sprayers cannot be damaged by pesticides and their solvents.
7. Start the pump and operate all controls enabling the
liquid to come in contact with all the components.
Leave the distribution valves until last. Some detergents and deactivating agents work best if left in the
tank for a short period. Check the label. The SelfCleaning Filter can be flushed by removing the bypass hose from the bottom of the filter. Stop the pump
and remove the hose. Start the pump for a few
seconds to flush filter. Be careful not to lose the
restrictor nozzle.
8. Drain the tank and let the pump run dry. Rinse inside
of the tank, again letting the pump run dry.
9. Stop the pump. If the pesticides used have a tendency
to block nozzles and filters, remove and clean them
now. Also check for sediment on the pressure side of
the safety valve for the Self-Cleaning Filter.

10. Replace all the filters and nozzles and store the
sprayer. If, from previous experiences, it is noted that
the solvents in the pesticide are particularly aggressive, store the sprayer with the tank lid open.

The maintenance and renewal intervals for the following
will depend very much on the conditions under which the
sprayer will be operated and are therefore impossible to
specify.
If it becomes difficult to build up sufficient pressure or if
pressure fluctuations occur, it may be necessary to
renew cone and cylinder. A HARDI kit is available for this
purpose. Ref. no. 741293.

1. Clean the sprayer completely - inside and outside - as
described under Cleaning of the sprayer. Make sure
that all valves, hoses and auxiliary equipment have
been cleaned with detergent and flushed with clean
water afterwards, so no chemical residue is left in the
sprayer.
2. Renew possible damaged seals and repair possible
leaks.
3. Empty the sprayer completely and let the pump work
for a few minutes. Operate all valves and handles to
drain as much water off the spraying circuit as possible. Let the pump run until air is coming out of all
nozzles. Remember to drain the rinsing tank also.

In cases where breakdowns have occurred, the same factors always seem to be the problem:
1. Minor leaks on the suction side of the pump will reduce the pump capacity or stop the suction completely.
2. A clogged suction filter will hinder or prevent suction so that the pump does not operate satisfactorily.
3. Clogged up pressure filters will result in increasing pressure at the pressure gauge but lower pressure at the
nozzles.
4. Foreign bodies stuck in the pump valves with the result that these cannot close tightly against the valve seat. This
reduces pump efficiency.
5. Poorly reassembled pumps, especially diaphragm covers, will allow the pump to suck air resulting in reduced or
no capacity.
6. Hydraulic components that are contaminated with dirt result in rapid wear to the hydraulic system.
Therefore ALWAYS check:
1.Suction, pressure and nozzle filters are clean.
2.Hoses for leaks and cracks, paying particular attention to suction hoses.
3.Gaskets and O-rings are present and in good condition.
4.Pressure gauge is in good working order. Correct dosage depends on it.
5.Operating unit functions properly. Use clean water to check.
6.Hydraulic components are maintained clean.
