8MAINTENANCE
(to carry out with the internal combustion engine stopped or the plug detached for electric motors).
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, page 18 )
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.
8.2EMPTYING TANK
The
When cleaning the interior of the cistern, all the washing liquids can be conveyed toward the tap indicated to the side.
We advise connecting the supplied tube in order to avoid discharging the liquid directly onto the unit and its structure.
8.3ROUTINE 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
=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.
8.4EXTRAORDINARY 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.
8.5REPAIRS
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 4.1 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.
