BK operating unit
The BK operating 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 unit
EVC - Electrical Valve Control. The ON/OFF is linked to
the section valves, which results in a very quick re-
sponse to ON/OFF. The operating unit is constructed of
modules and is electrically controlled via a remote
control box. The unit is fit with built-in HARDI-MATIC.
HARDI-MATIC ensures a constant volume per hectare
of the liquid (l/ha) at varying forward speed within the

Boom
The sprayer can be fitted with VHY or VHZ boom. Both
booms are supported by a trapeze which is 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 12, 12.5, 15, 16 and 18 m
working width. Alternative boom widths are possible for
the VHZ model. All booms are provided with spring
loaded
breakaway.

The HARDI MASTER 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 spray 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.
1. 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.
2. 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.
3. 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.
4. Do not touch or stand on the transmission shaft when
it is rotating - safety distance: 1.5 meter.
5. Prevent protection guards from rotating by attaching
the chains allowing sufficient slack for turns.
6. Make sure that protection guards around tractor
P.T.O. and implement shaft are intact.
7. Always STOP ENGINE and remove the ignition key
before carrying out maintenance or repairs to the
transmission shaft or implement.

First installation of the transmission shaft is done in 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 a minimum overlap.
The size of this overlap depends on the pump model:
Pump with 6 splines/540 r.p.m.
The shaft must always have an overlap (A) of minimum
1/3 of the length.
Pump with 21 splines/1000 r.p.m.
The shaft must always have an overlap (A) of minimum
2/3 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. Fit the shaft to tractor P.T.O. and sprayer pump shaft.
NOTE! Female part marked with a tractor towards
tractor!

has 4 settings.
Setting 1: For use on uneven ground with many obsta-
cles.
Setting 2: All-round standard setting (Factory setting)
Setting 3: Slightly slower mowing trapeze. Good at
following slopes, but less compensating for
obstacles.
Setting 4: Very slow moving trapeze. For use on even
ground and slopes where there are no
obstacles.
How to alter the setting
1. Unfold and support the boom.
2. Loosen bolt from locking hole (A).
3. Remove pin + mounting (B).
4. Place (B) in new setting position (1-4).

WARNING! Before unfolding the boom it is
important to connect the sprayer to the tractor to
prevent overbalancing of the sprayer.
DANGER! When folding or unfolding the boom,
make sure that no persons or objects are in the
operating area of the boom.
DANGER! Always follow the guidelines listed
below when driving in areas with overhead power
lines:
Never use the folding/unfolding functions in areas
with overhead power lines.
Unintended boom movements can cause contact
with overhead power lines.
NOTE! A label (ref. no. 978448) follows the sprayer. This
label must be placed in the cabin at a place visible from
the operator’s seat.

Review - MANIFOLD system
The MANIFOLD system is located at the left side of the
sprayer and permits operation of the liquid from one
position. 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.
Symbols
The valves are distinguished by coloured identification
discs on the 3-way valves. Symbols corresponding to the
optional extras are located on the discs for easy identifi-
cation and operation.
A function is activated/opened by
turning the handle towards the
desired function.
IMPORTANT! Only the functions
in use should be open - always
close remaining valves.

The green pressure valves and the black suction valves
have 4 positions. Two positions are for options. The
other two are marked “O” indicating the valve is closed.
The blue return valve only has 2 positions.
The arrow on the handle indicates which position is
selected.

To select the optional equipment, the handle is turned so
the arrow and thereby liquid is directed to the optional
extra instead of to the self-cleaning filter/operating unit.
When spraying is to resume, turn the handle so the self-
cleaning filter/operating unit is selected.
If 2 or more valves are fitted, the arrow must point
towards the optional extra you select. Remaining
handles are turned to “O” (closed). When spraying is to
resume, select the self-cleaning filter/operating unit. The
other handles are turned to “O”.
If all the green pressure valves are closed the safety
valve will open inside the tank.

Turn the handle so the arrow points towards the selected
optional equipment. The handle is turned back when you
want to aspirate from the main tank.
If 2 valves are fitted, e.g. front tank and rinsing tank,
select optional extra and turn the other valve to “O”
(closed). To resume aspiration from the main tank, the
arrow must point towards the main tank.
Remaining valve must be closed.

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 instead
of to the tank return.
