Wide-range nozzle (7):
When spraying plants and trees we recommend fixing
the wide-range nozzle (7) onto the red standard nozzle
(4). This ensures that a large area can be sprayed at
one time. Push the wide-range nozzle onto the
standard nozzle, until the bead engages.
In narrow spaces and for aftercare, we recommend
placing the wide-angle grille (7a) onto the wide-range
nozzle. This ensures that the spray velocity is reduced
and the spray is applied more widespread, to prevent
damage to leaves.
Nozzle attachment (6):
The nozzle attachment (6) is positioned onto the
standard nozzle (4) with the selected grille.
Use the dual grille (6a) when spraying cultures in rows
(e.g. vines, tomatoes, nurseries), to achieve a good
covering on the underside of the leaves.
The deflector grille can be replaced with a dual grille
(6b). The dual grille provides a 90° - 110° spray
pattern. The dual grille is usually used for spraying two
rows at a time. The deflector grille and the dual grille
can be placed onto the external diameter of the nozzle,
until the bead engages.
Dual nozzle (accessories, part no.: 49 00 137):
Remove standard nozzle (4) from the spray wand and
push the dual nozzle onto the spray wand.
7.4 Residual spray medium
Switch off the appliance as soon as no further liquid is
expelled, when the metering body is correctly
positioned for spraying, or air bubbles are visible inside
the lance supply hose.
The tank will then contain less than 100 ml residual
medium.
If you don’t want to refill the tank with spray medium
and you want to terminate spraying, dilute the residual
medium with 2 l of water. Dispose of this solution on
the treated area.
7.5 Strainer for accessory sets
When using the liquid pump (accessory part no.:
type 444 Î 44 00 114, type 450 Î 44 00 235) or the
ULV accessory (part no.: 49 00 479), a strainer is
integrated into the tank connector.
The strainer has a mesh size of 0.32 mm. Only use
original strainer part no.: 25 00 198 with standard mesh
size when replacing the strainer.
7.6 Checking the spray medium flow rate
At the beginning of the spraying season, check whether
the equipment flow rate (l/min) still corresponds to the
„Guide values“ table (see also item „Maintenance
schedule“).
For this, fill the equipment up to the maximum marker
with water, start using the equipment and spray for one
minute exactly at maximum operating pressure. Then
measure the water volume required to bring the water
level back up to the maximum marker.
The actual volume measured represents the flow rate
of the equipment in l/min at maximum operating
pressure.
It should not deviate by more than 10 % from those
listed in the „Guide values“ table. Should the actual
value be too low, sediments inside the metering body
may be the cause. Clean the corresponding parts and
repeat the checking procedure.
