When spraying plants and trees we recommend fixing the

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.

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.
