8MAINTENANCE

(To be done with the machine and cardan shaft stopped)

The maintenance of the sprayer is essential for maintaining a high level of safety. Also consult the single handbooks of the main components of the sprayer.

All of the maintenance operations and repairs must be carried out with the machine and cardan shaft stopped and the tank and circuit clean of any residues of chemical products.

8.1PROGRAMMED MAINTENANCE ( TAB. N° 7)

We recommend using a table of programmed maintenance to follow in time to keep the sprayer in an efficient working condition.

For major and important maintenance jobs we recommend using the normal UNIGREEN assistance service available from your reseller, using original UNIGREEN spare parts.

8.2ROUTINE MAINTENANCE

=After every treatment, wash the inside of the tank and the entire circuit as indicated in paragraph 4.13

=Periodically check that the suction and delivery filters are clean (see figure)

=Check the oil level in the volumetric compensator of the pump, as indicated in paragraph 5.1.1

=The use of chemical products that are particularly damaging for a nitrile rubber mix (ex.. herbicides and products for rice fields) can cause the diaphragm to break before time.

In these conditions check the state of the components more often.

8.3EXTRAORDINARY MAINTENANCE

At the end of a season of intense use, or every two years of normal use, it is a good idea to have a specialised service technician perform a general check on the machine.

8.4MAINTENANCE OF THE HERBICIDE BOOM - SELF-LEVELLING DEVICE - LIFTING SYSTEM

(to be done with the machine and cardan shaft stopped)

a) Check the state of wear of the nozzles and replace them when the delivery is over 30-35% of the theoretical level. Don’t clean with nails, bradawls or punches. Use small brushes or compressed air.

- drain the pressure and stop the machine

- dismantle the screw or bayonet ring nuts holding the nozzles

- clean with a small brush or compressed air, don’t use nails, punches or bradawls - reassemble the nozzles and the ring nuts, replacing the filters and seals.

b) Keep the joints greased.

c) If you are using the boom and you notice excessive pitching or the same closing on sloping ground, you can load the spring more by screwing in the relevant nut. d) If the external arms droop downwards after some use you can realign them using the relevant adjustment screws:

- unscrew the locknut

- adjust the inclination by screwing in the screw

- tighten the locknut again to stop it unscrewing accidentally.

8.5REPAIRS

We recommend having the normal UNIGREEN assistance service available from our reseller perform any repairs or contact a specialised workshop. During all of the repairs, in particular when welding, the machine and the circuit must be clean of any residues of chemical product.

If the machine has to be lifted (for example to change a wheel) follow the instructions in point 4.3 of the present handbook.

Also make sure the machine is stopped, connected to the tractor, and use the relevant chocks to block the wheel still on the ground.

If you use a jack (manual or hydraulic) make sure you use a jack that is suitable for the frame so it can’t slip and put it in the right position. The jack must be placed under the main frame of the machine near the wheel to change. Make sure the ground is compact: if necessary use wooden beams or other sufficiently resistant material to broaden the supporting base of the jack.

8.6STORAGE IN A WAREHOUSE AND TRANSPORTATION

The sprayer must be kept in a closed place away from excessive humidity and protected from frost. Especially if electrical pressure regulators, electrical motors, a spraying computer or similar components are fitted.

Before storing the machine, after you have washed it, apply a light coat of oil.

If the temperature might drop to below zero, drain any residual liquid or add roughly 0.5 L of normal antifreeze for auto vehicles.

To transport the machine follow the instructions in point 4.3 of the present handbook.

CAMPO 11 - 16 - 22 - 32, DSP 11 - 16 - 22 - 32 specifications

Unigreen DSP Series and CAMPO Series are advanced agricultural sprayers designed to meet the evolving needs of modern farming. The Unigreen DSP (Dynamic Spraying Product) models 11, 16, 22, and 32, along with the CAMPO models of the same specifications, are engineered for efficiency, precision, and reliability in crop protection.

One of the key features of the Unigreen DSP models is their innovative spraying technology. Each model is equipped with a high-capacity tank that allows for extended operation without the need for frequent refills. The DSP series incorporates adjustable booms that provide precise application across various crop types. This ensures uniform coverage and minimizes waste, making it an environmentally friendly option for farmers.

The CAMPO series also boasts similar tank capacities and boom adjustments, making them suitable for diverse agricultural applications. Both series offer customizable options, allowing farmers to choose the configuration that best fits their land and crop requirements.

Another standout characteristic of both Unigreen and CAMPO sprayers is their user-friendly interface. Equipped with advanced electronic controls, farmers can easily monitor and adjust spray rates, pressure, and other critical parameters in real time. This technology not only enhances the sprayers' operational efficiency but also aids in achieving the optimum application rates for different pesticides and fertilizers.

Furthermore, both series integrate cutting-edge GPS technology, enabling precision agriculture practices. This feature allows operators to map their fields, ensuring that every inch is accurately treated, while also reducing the possibility of overlap or missed areas. This precision application reduces chemical usage and ultimately leads to cost savings.

Durability is another primary focus in the design of the Unigreen DSP and CAMPO sprayers. Built with high-quality materials that can withstand harsh environmental conditions, these sprayers promise longevity and consistent performance over time.

In summary, Unigreen DSP and CAMPO models 11, 16, 22, and 32 are technologically advanced agricultural sprayers that combine efficiency, precision, and durability. With features such as adjustable booms, advanced electronic controls, and GPS technology, they cater to the diverse needs of today’s farmers, helping to enhance productivity while minimizing environmental impact. These sprayers are positioned to play a pivotal role in the future of sustainable agriculture.
