Spraying:
Approach the target object with the engine at
idling speed. Accelerate to full engine speed, then
open formula on-off tap.
Wide-range nozzle (18):
When spraying plants and trees we recommend
fixing the wide-range nozzle (18) onto the red
standard nozzle (15). 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 (18a)
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 (19):
The nozzle attachment (19) is positioned onto the
standard nozzle (15) with the selected grille.
Use the dual grille (19a) 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 (19b). 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.: 49137):
Remove standard nozzle (15) from the spray wand
and push the dual nozzle onto the spray wand.
12.2 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.
12.3 Strainer for accessory sets
When using the liquid pump (accessory part no.:
49117) or the ULV accessory (part no.: 49480), a
strainer is integrated into the tank connector.
The strainer has a mesh size of 0.32 mm. Only use
original strainer part no.: 12289 with standard
mesh size when replacing the strainer.
12.4 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.
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.
