1. INTRODUCTION
The sprayers of the series VRA and VCRA are machines for agricultural plant protection in
wine yards and orchards. They transfer the protection agent with an air stream to the plants.
The success of the protection depends on the protection agent, the technique of the protection
and the user. However, we must not only look the efficiency of the spraying, we must also take
care of the environment and the best results always achieved by a symbiosis of the
components.
The series VRA and VCRA sprayers are state of the art products for agricultural plants
protection, their air deflector and fan constructed to provide the best results in plant protection.
Their construction reduces also the noise, the necessary horsepower and the burden on the
user.
With the sprayers series VRA and VCRA, we can protect the plants:
a) Sprinkle 800 - 1500 l/ha
b) Spraying
- Rough spraying 400 - 800 l/ha
- Fine spraying 100 - 400 l/ha
- Very fine spraying do 100 l/ha (only with electrostatic)
In modern plant protection we rarely use high amounts of water (800 - 1500 l/ha), because it is
uneconomical- the loss of the protection agent is enormous (The droplets combine and flow of
the leaf- by 1500 l/ha almost 50 %) and the pollution (ground water).
Spraying with 400 - 800 l/ha are already treated as concentrated plant protection, where the
concentration is from two to four times.
Fine spraying 150 - 400 l/ha has a concentration from four - eight times.
Very fine spraying comes in consideration only in use of electrostatic and spraying every
second row.
The quantity of the protection agent used depends on the technique used and the habitat of the
plant. With the use of our sprayers, you will be able to reduce the luxury consumption of the
protection agent, protect the environment and increase the productivity.

2. GENERAL SAFETY ADVICE
Before starting work ensure, that you understand all the equipment and actuation
elements of the machine and their function. There is no time for this when the machine
is already in operation. Before starting up the machine each time, all the safety and
protection equipment must be properly attached and fully functional. Check the
machine at least before every operation for visible damage and check the function of
safety and protection equipment.
EXTREME CAUTION while working with chemical mixtures.
The sprayers from the series VRA and VCRA have been manufactured
according to the state of the art and the certified safety regulations. Nerveless,
the operation of the machine could be dangerous if it not used properly.
1. For your own safety always, wear personal protection wear, like boots, gloves and hat.
2. Avoid the contact between skin and toxic mediums.
3. When you work with toxic mediums, always be sure, that you have near clear water and
that clean water tank is full.
4. Do not leave the toxic mediums or they package outside or in rooms, where they are in
reach of children or unauthorized persons.
5. Equipment used for toxic mediums should never be used for work with food, drinks and
clean water, we recommend that you mark these items and deposit them in a safe place.
Do not drink, eat or smoke whilst spraying or working with contaminated
equipment.
6. Store the sprayer always in a safe place where the slope should not be more than 8, 5°.
7. Avoid working when the wind is greater than 3 m/s – possible droplet carrying.
8. While the sprayer is working, avoid staying in the wind stream.
Rotating parts are attractive to children, so be sure that there are no children
while the sprayer is operating.

4. DESCRIPTION
The sprayer from series VRA and VCRA should be used for:
-Spraying in wine yards and orchards, with protection agents that are free in sale,
with the consideration of their manufacturer manuals.
-Work in wine yards and orchards with a row width till 4,5m (VRA) / 8,0 m (VCRA)
and a maximal culture height of 4,0 m (VRA)/ 6,0 m (VCRA) (look at table on page
27).
When the machine is not anymore for use, do not throw it away anywhere, but bring it
back to your seller, who will take care of the proper destruction of the machine.
Implications by the use of certain pesticides
We would like to draw attention to the fact that prolonged exposure (20 hours)
to protection agents which are familiar e.g. Laso, Betanal and Tramat, Stomp, Iloxan,
Mudecan Elancolan and Teridox can cause damage to the pump diaphragms, hoses,
spray lines and tanks. Therefore, prolonged stay of pesticides in containers, pump and
spray system for more than 15 hours is prohibited. When using such aggressive plant
protection products, the immediate spreading of the spray mixture and the subsequent
rinse with clean water is recommended. In particular we warn against unauthorised
mixtures of two or more different crop protection agents.
Observe the information on compatibility of crop protection agents and
substances for the sprayer. Do not spray any crop protection agents which have
a tendency to stick together or set.
We would also like to draw your attention to use of bio protection agents, which
can also cause damage to the parts of the pump and other parts of the sprayer.
Do not use chemical agents which are abrasive, because they can cause fast
wear of parts of the pump and other parts of the sprayer.
As a substitute for standard pumps, the pumps made of brass are also available,
which are more resistant if using particular spraying agents.
For sprayer used materials and components are liquid fertilizer proof.
WARNING !

6. WORKING PRINCIPE OF THE SPRAYER
The protection agent flows from the tank through the sucking filter to the pump and from pump
under high pressure through the pressure filter to both spraying sides. With the pressure
regulations valve you can regulate the pressure with the turn the pressure regulation handle to
the right (clockwise) to increase the pressure, or to the left (counterclockwise) to decrease the
pressure.
Before you run the sprayer, turn the regulation handle to the left, so that there is no pressure
on the manometer. When you have working rpm, turn the handle to the right so long, that you
achieve the wanted pressure on the manometer
When the nozzles are closed, all fluid is returning to the tank, when they are operating, a part
of the fluid is for spraying and a part returned in the tank.
Tank mixers must be always on, to secure the homogeneity of the protection agent. When the
level of the fluid sinks under 20 l, you must close them to prevent foaming.
Do not work with pressure above 15 bars. With to high pressure the
efficiency of spraying sinks. For a higher range of droplets, increase the rpm
of the fan, not the pressure!

WORKING SCHEME OF THE SPRAYER
7. BEFORE USE
Read the operator` s manual near the sprayer and check the written on the machine.
After studying of the manual, you can begin with the operating with the sprayer, but make it as
written in the manual described.
We recommend the next steps:
1. Connect the sprayer.
2. Control if it is working properly.
3. Fill the tank with water.
4. Turn the P.T.O. on and check if the pump and the pressure unit are working
properly.
5. Check all connections and nozzle holders.
6. Turn the P.T.O. off.
7. Clean the sucking and pressure filter.
8. Make a test spraying with clean water and a speed test (100 m test).
9. After the test spraying or the first two hours of spraying check all screws,
especially on the pump and the fan multiplier.

OCT-16 PAGE 13
8. PREPARATIONS FOR THE WORK
8.1. CONNECTING THE SPRAYER
The sprayer can be connected to every tractor with a standard three point system categories I
and a right hand transmission (also available as left turning). Attach the bolts on the fork to the
tractor and secure them with a pin.
Danger- you could be squeezed between the sprayer and the tractor
While you are connecting the sprayer to the tractor always turn the tractors machine off. Also
do not move the tractors hydraulic handle. The tractors arms should be lateral stabilized and
secured with a spring pin. Make sure that the pins are not loaded sideways- they could break.
If the tractors arms are not lateral stabilized, the sprayer could turn over-
danger for people and the machine
When the sprayer is being lifted or lowered, make always sure that no one
is near the machine (1,5m), if not so someone could get hurt.
When the sprayer is being connected, consider the whole weight of it. In
general it is recommended:
1. Putt weights on the front of the tractor
2. Increase the pressure in the tires (consider the tractors manual)).
3. Drive slowly, especially when the tank is full (longer braking distance,
cradling)
4. Be careful when lifting the full sprayer the first time
8.2. P.T.O. CHOICE
For the sprayers of the VRA series a WALTERSCHEID P.T.O. size W 2300 or W 300 E are
recommended. For the sprayers of the VCRA series a WALTERSCHEID P.T.O. size W 400 E
in right length are recommended.
8.3. CHOOSING THE RIGHT P.T.O. LENGTH
Lift the sprayer so high that the P.T.O. s' are in the same height- the shortest distance between
them.
WARNING !
WARNING !
WARNING !
WARNING !

PAGE 14 OCT-16
Dismantle the P.T.O. and put every part alone on the P.T.O. s'. Mark the needed length, but
consider that the parts should cover each other minimum 150 mm (by a P.T.O. < 1 m).
Consider also the minimum length when assembling.
A too long P.T.O. can damage the tractor or the pump.
When the tubes are shortened, make sure that there are no sharp edges. Before assembling
the P.T.O. grease the inner tube and make sure that the tubes are fitting well together.
Cut the plastic protection tube 20 mm more than the steel tubes.
When you are connecting the P.T.O. to the tractor and pump make sure that it moves free-
that there are no obstacles.
When the P.T.O. is working, the angle should not be more than 15 degrees.
For the personal safety it is important that the plastic protection tube
covers the whole P.T.O. and that the protection also covers the U joints. Do
not forget to set the chain length so that the protection cannot rotate.
WARNING !
WARNING !

OCT-16 PAGE 15
8.4. GREASING THE P.T.O.
Grease the P.T.O. in intervals as shown in the picture below and after long pauses.
DO not use the P.T.O. as a stair- it can cause serious injuries. Do not use
P.T.O. with damaged protection. Always use a P.T.O. with the CE
certificate.
9. FILLING AND EMPTYING THE TANK
EXTREME CAUTION IS NEEDED WHEN THE TANK IS FILLED FROM THE
PUBLIC WATER NETWORKS OR WATER DAMS.
If the safety regulations are unconsidered, people, animals or plants could be poisoned.
Filling from the public or private water networks
Consider the laws and regulations, which are valid for water supply.
By filling the tank from a water network always have a distance between the hose and the tank.
The distance should be minimum 10 cm or 2 times the diameter of the hose.
WARNING !
WARNING !

PAGE 16 OCT-16
Filling from a dam, brook or a river
For that kind of filling, you must have permission from the water department.
Filling from a tank
The threat that is present by filling from a tank is spilling; never leave the sprayer while filling.
Height of the filling
The tank can be filled only to the sign MAX on the scale. The rest is for
the foam and the decanting of the suspension, while working on slopes.
Emptying the tank
Rotate the red handle of the ball valve on the lower part
of the tank – see photo. Putt a vessel under the outlet,
which will hold the fluid, then turn the red handle, to
empty the tank. After total emptying the tank, turn the
handle back in the work position.
10. HOW TO USE THE REMOTE UNIT
The one hand unit BY MATIC is used to engage the pressure and to open (or close) the left
and the right nozzles.
Handle positions:
1. Left and right side closed, all fluid is returned to the main tank (by pass). On the
manometer is no pressure.

OCT-16 PAGE 17
2. The left side is open.
3. The left and the right side are open.
4. The right side is open.
5. Left and right side closed, the pump is on the adjusted pressure. In this position the
powder mixer can be used and the tank mixer.

PAGE 18 OCT-16
Pressure adjustment:
-Put the handle as shown in figure 5
-Open the pressure regulation handle (turn against the clock)
-Put the gear in and set the working revolutions
-Turn the pressure regulation handle (like the clock) to set the desired pressure (depends on
the nozzles)
-Make the pressure correction with open nozzles and every time when you change the
number of the opened nozzles
11. WORKING WITH THE SPRAYER
For the working test, fill the tank with water and turn the pressure regulation handle to the left,
then turn the P.T.O. slowly on. Run the P.T.O. with middle rpm and check the pump and fan.
Open the left and right side, then turn the pressure handle, until the wanted pressure is
reached (max. 15 bar). Check if the spraying angles are uniform; make a test spraying to
check the quality and the consumption of the fluid. After the test, you can put the protection
agent in the tank. The consumption of the agent you can calculate with the calculators of the
fluid consumption and the spray rate chart.
IMPORTANT
Never use nozzles with different holes (color). If you want to increase the agent deposit in
some areas of the plant, use more nozzles, not different nozzles. For every nozzle type are
certain pressures defined, that should not be exceeded. If you increase the pressure above the
optimum, the droplets become too small and they vaporize before the leaf. If the pressure is
too small, the droplets are too big and they flow off the leaf- the protection is uneconomic.
Do not work with more than 540 rpm on the P.T.O., more rpm could cause
serious damage to the pump and the rotating part of the sprayer. In such
case, the warranty is not valid.

12. CLEANING THE SPRAYER
The whole sprayer must be cleaned after the work. Never start operation if the sprayer
wasn’t cleaned properly. Due to toxic vapours in the spray liquid tank, climbing into the
tank is always forbidden.
If the manual of the protecting agent contains cleaning, advices consider
them. Consider also the region laws for the protection agent removal and
their packaging.
The sprayer should be cleaned only in places, where you do not represent a threat to the
environment (contamination of the water in wells, springs…). The water used in the cleaning
process should be sprayed in the plantation with increased speed.
Do not clean the sprayer in places, where cleaning water could flow into
canalization or other water systems.
DIRTY SPRAYERS REPRESENT A DANGER TO CHILDREN AND ANIMALS.
Never leave a dirty or full sprayer without supervision. If not so, leave it in a place where it is
unreachable for unauthorized personal or animals.
12.1. CLEANING THE SYSTEM WITH A FULL TANK
WARNING !
WARNING !
WARNING !

PAGE 20 OCT-16
If you had to stop spraying before time (wind, rain, defect…)
and you have in your tank fluid, you can clean the pump and
the system with the water from the clean water tank.
Disengage the P.T.O. and turn the handle on three-pole valve
as shown in the picture (Position H2O).
Turn also the handle on three- pole valve (on the return cycle)
of tank so (shown in the picture), that the long part of valve
handle is turned away from the tank. Open the nozzles; engage
the pump and spray until the clean water tank is empty. Close
the mixers too. When you finish, turn the handles in their first
position. This procedure cleans the system enough, so that
there will not be any problems when the work will be continued.
12.2. REMOVING THE TECHNICAL LEFTOVER
We consider as a technical leftover the fluid in the tank, that
cannot be used - because of the tank shape, fluid in the pump,
hoses and filters. The technical leftover must be watered in a
1:10 proportion and sprayed in the plantation. For thinning of
the technical leftover we can use the water from clear water
tank for system washing.
Close the nozzles and put the pump on, wait until it is good
mixed, and then spray it in the plantation.
