Identification plate
An identification plate fitted on the frame indicates model
and serial no. 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.
DescriptionDescription
DescriptionDescription
Description
Frame
Strong and compact frame which has a strong chemical
and weather resistant electrostatic lacquer coat.
Screws, nuts, etc. have been DELTA-MAGNI treated to
be resistant to corrosion.
Front tank
UV-resistant Polyethylene in a suitable design with no
sharp corners for easy agitation, emptying, and cleaning.
Nominal contents: 1000 l or 1300 l.
Pump
Diaphragm pump with 6 diaphragms, model 463, with
easily accessible valves and diaphragms. Standard =
540 r.p.m, optional = 1000 r.p.m.
MANIFOLD SYSTEM
All functions of the spray circuits are operated via the
centrally situated MANIFOLD valves with colourcoded
plates and pictorial symbols for easy operation.
Operating unit
The operating unit is constructed of modules and con-
sists of main ON/OFF valve, pressure gauge, pressure
regulation with built-in HARDI-MATIC and distribution
valves with pressure equalization. HARDI-MATIC en-
sures 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/min
(for pump/540 r.p.m.) or 650-1100 r/min (for pump/1000
r.p.m.).
The operating unit is fully electrically controlled (EC) via
remote control box.
Filters
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. Also suction filter
and nozzle filters are standard. In-line pressure filters
can be fitted as option.
Boom
The sprayer is equipped with a HAZ boom, avaliable in
18, 20, 21 and 24 m working width. The boom is sus-
pended in a strong, stable parallelogram boom lift and is
fully hydraulically operated, including boom slanting
control and air slot angling. The HAZ boom has Direct
Acting Hydraulics (D.A.H) and individual boom tilt
function as well.
All boom widths can spray 12 m with outer sections
folded.
The TWIN blowers are driven by a built-in hydrostatic
transmission, powered via the tractor P.T.O. Blower
speed can be adjusted stepwise from the tractor cabin.

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 usespray equipment, it is strongly recom-
mended 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.

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 discoloring 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.

To avoid accidents and personal injuries, note the
following recommended precautions and safe operation
practices.
Always STOP ENGINE before attaching the transmis-
sion shaft to tractor P.T.O. - most tractor P.T.O. shafts
can be rotated by hand to facilitate spline alignment,
when engine is stopped.
When attaching the shaft, make sure that the snap lock
is FULLY ENGAGED - push and pull shaft until it locks.
WARNING! ROTATING TRANSMISSION
SHAFTS WITHOUT PROTECTION GUARDS
ARE FATAL.
Always keep protection guards and chains intact and
make sure that it covers all rotating parts, including CV-
joints at each end of the shaft. Do not use without
protection guard.
Do not touch or stand on the transmission shaft when it
is rotating - safety distance: 1.5 meter.
Prevent protection guards from rotating by attaching the
chains allowing sufficient slack for turns.
Make sure that protection guards around tractor P.T.O.
and implement shaft are intact.
Always STOP ENGINE and remove the ignition key
before carrying out maintenance or repairs to the trans-
mission shaft or implement.

First installation of the transmission shaft is done the
following way:
1. Attach sprayer to tractor and set sprayer height in the
position with shortest distance between the tractor
and sprayer pump P.T.O. shafts.
2. Stop engine and remove ignition key.
3. If transmission shaft must be shortened, the shaft is
pulled apart. Fit the two shaft parts at tractor and
sprayer pump and measure how much it is necessary
to shorten the shaft. Mark the protection guards.
NOTE! The shaft must always have an overlap of
minimum 1/3 of the length.
4. The two parts are shortened equally. Use a saw, and
file the profiles afterwards to remove burrs.
5. Grease the profiles, and assemble male and female
parts again.
6. Grease the tractor P.T.O. and pump shafts.
7. Fit the shaft to tractor P.T.O. and sprayer pump shaft.
Note: Female part marked with a tractor towards
tractor! Twist the collar and slide the yoke onto the
P.T.O. shaft. Make sure
that the lock engages by
pushing and pulling the
shaft forwards and
backwards. Fit the
chains to prevent the
protection guards from
rotating with the shaft.
8. When operating,
ensure that joint
angles are equal.
Disengage the
P.T.O. when the
angle of the joints
exceeds 35o

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.

Unfolding the boom
NOTE! Ensure that the transport safety chains are
removed and that the booms are clear from the trans-
port brackets before unfolding.
1.Push switch 1upwards to lift the boom clear of the
transport brackets.
2.Push switch 2upwards to unfold the inner sections.
Rear transport hooks disengage automatically.
3.Push switsches 6 and 7 downvards to lower individual
tilt rams.
4.Push switch 3upwards to unfold outer sections.
5.Push switch 4to correct slant angle.
6.Push switch 1downwards to lower the boom to correct
height above crop or ground level.
7.In order to reduce wind drift and/or increase penetra-
tion of spray liquid in the crop, the slot angle can be
changed backwards and forwards with switch 5.
IMPORTANT! The two upper functions in the red rectan-
gle with STOP signs must only be operated when
sprayer is stationary! Failure to do so will damage the
boom.
Folding the boom
1.Check that the slanting function is midway 4.
2.Set slot angle at midway 5.
3.Raise boom 1to upper position.
4.Fold outer sections 3
5.Lift individual boom tilt 6and 7
6.Fold inner sections 2. Rear transport hooks
engage automatically.
7.Lower boom 1until boom rests on transport
brackets.
Hydraulic slanting control
The hydraulic slanting control 4enables slanting of the
entire boom hydraulically. This is advantageous when
spraying across hillsides.
Reset position to neutral (midway) before folding the
boom.
Boom tilt function
The boom tilt function control 6and 7enables you to
adjust the boom height individually in right and left-hand
side.
Air slot angling
The air slot and nozzle assembly can be angled approx.
40º forwards and 30° backwards compared to vertical
position. Regarding adjustments - see section on
“Air technique”.
Electric fan speed adjustment (if fitted)
Increasing of fan speed
Decreasing of fan speed
The max. revolutions for the fan are 3100 r.p.m., which
will give full air speed of approx. 40 m/sec (90 mph).
The fan speed is indicated by the transmission working
pressure by means of a pressure gauge. (Please see
the part “Air Technique”).
Conversion table between pressure and fan speed - see
the part “Air Technique”

GB 07 02 02
IMPORTANT! To avoid shock starting the fans always
set fan speed to 0 before engaging the P.T.O.
Boom support wheels
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!
Boom suspension sensitivity
The boom suspension would normally suit most condi-
tions and would not require any adjustment. The sus-
pension 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.
Add 1-4 pcs. of 10 mm spacers as shown at each rod
until the decired function is reached.

Water can be filled into the main tank in following ways:
1. Filled through tank lid.
2. Filled by diaphragm pump through a suction side fitted
filling device (optional extra) using normal pump
capacity directly to the tank.
3. Filled by diaphragm pump through a pressure side
fitted injector/venturi type Fast Filling Device (optional
extra) using up to 3 times normal pump capacity.
4. Combination of 2 and 3.
The tank should normally be filled 1/3 with water, before
adding the chemicals.
Always read instruction on chemical container!
NOTE! Max. permitted tank contents:
Filling through tank lid
Remove tank lid and fill water through strainer to prevent
rust or other particles to enter the tank.
An overhead tank can be used in order to obtain high
filling capacity.
It is recommended to use as clean water as possible for
spraying purposes.
WARNING! DO NOT LET FILLING HOSE ETC.
ENTER THE TANK. KEEP IT OUTSIDE THE
TANK, POINTING TOWARDS THE FILLING
HOLE.
IF THE HOSE IS LEAD TO THE BOTTOM OF THE
TANK, AND THE WATER PUMP AT THE WATER
SUPPLY PLANT STOPS, CHEMICALS CAN BE SI-
PHONED BACK AND CONTAMINATE THE WATER
SUPPLY LINES.
Suction Filling Device (if fitted)
WARNING! Avoid contamination or personal
injury. Do not open suction valve towards
Suction Filling Device unless pump is run-
ning and filling hose is connected. If this valve is
opened without pump running, liquid will stream out
of the MANIFOLD.
The Suction Filling Device is operated as follows:
1. Remove cover A, and connect suction hose Bto
Suction Manifold.
2. Engage diaphragm pump and set P.T.O. revolutions at
540 r/min or 1000 r/min depending on pump model.
