5.6 MARKER
The marker indicates the zone where the treatment has been applied.
It produces a chemical foam that doesn’t damage the crops, which is
deposited on the ground and disappears after roughly an hour. The marker is
an accessory available on request. For the use and maintenance of the
system follow the instructions in the specific handbook in the package or
enclosed with machine manual.
WARNING: the foam liquid is ruined by frost, very hard water can change the
yield and function.
6 HAND LANCES
When using hand lances bear in mind the following notes:
= Don’t direct the jet of liquid towards electric power lines or zones where
there is electrical current, houses or where people might pass.
= Don’t point the jet at people or animals.
The jet can cause serious injuries simply due to the mechanical force of the
liquid under pressure.
= Never block the spraying lever of the lance in an open position because if
the lance falls it will be uncontrollable.
= At the end of work after you have stopped the pump, make sure that any
residual pressure in the pipes under pressure has been drained to avoid
unexpected jets when putting the lance away.
There are various types of lances; with a lever, mitra spray gun and pistol grip.
For further information please refer to the handbook in the package.
The lever lance is controlled by opening lever A which, depending on how
much it’s pressed, produces a conical spray or direct jet. The standard nozzle
is Ø 1.5
The mitra spray gun can produce a direct jet or a conical spray and the type of
spray is selected by pushing lever B forwards or backwards. Use lever C to
open the jet. The standard nozzle is Ø 2.5
Replacement nozzles are available for all of the lances and the capacities are
indicated in the tables N° 3 e N° 4.
7 HOSE REEL
Available in the following sizes 20-50-100 , with mechanical, electrical and
hydraulic rotation.
To use the system, consult the enclosed handbook as there are significant
differences between each.
After work it is important to block the winding roller to stop the hose unwinding
while you are moving the sprayer.
8 MAINTENANCE
(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.
8.1 PROGRAMMED 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.
