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.

Danger of squeezing between the machine and the load, when it is
oscillating.
Do not stay near the P.T.O. injuries possible.
Do not go into the tanks- TOXIC.
DANGER: rotating parts- do not reach with your hands near the fan.
