5. Mount the spray screen (3232U) [5] on the spray wand (3232U) [8], then sealing ring
[11], insert [12] and nozzle [13]. (Fig. 3)
Checks
Visual inspection: Are the tank [1], pump [2], hose [3], shut-off valve [7] and spray wand [8]
or [9] with nozzle [13] undamaged? (Figs. 1 and 3)
Pay special attention to the connections between the tank – hose and the hose – shut-
off valve and to the condition of the pump threading and spray wand.
Pump up the empty device to 2 bar (Fig. 10).
No leaks:
The pressure must not decrease more than 0.5 bar within 30 minutes.
►
Function: Pull up the piston pressure gauge handle [14]. (Fig. 4)
The pressure must dissipate.
►
Activate the shut-off valve [7] (Fig. 12)
The shut-off valve must open and close.
►
Have damaged parts or parts that do not work properly repaired immediately by our
customer service department or by service partners authorized by us.
Making preparations
Observe the instructions in the section entitled "Safety".
1. Pull up the red piston pressure gauge handle [14] until the tank is depressurized. (Fig. 4)
2. Unscrew the pump [2] from the tank. (Fig. 5)
We recommend you mix the spraying liquid in the device or premix it in an external
tank: Fill to 1/3 with water, pour in the spraying agent, and then add more water until
full.
If used for HERBICIDES, this spraying device should no longer be used for applying
pesticides.
3. Add the spraying liquid to the tank [1] (Fig. 6)
4. Check the filling level with the scale [15] on the tank. (Fig. 6)
5. Screw the pump [2] into the tank. (Fig. 7)
6. Press the piston rod with handle [16] down and turn it clockwise.
The piston rod with handle is unlocked. (Fig. 8)
►
7. Create the desired pressure (→ Table 2) in the tank (Fig. 9)
The maximum pressure should not exceed 3 bar (red line on the piston pressure gauge,
Fig. 9). If the maximum pressure is exceeded, the safety valve will engage and release
the excess pressure.
8. Press the piston rod with handle [16] down and turn it clockwise. (Fig. 10)
Piston rod with handle is locked.

Spraying
Observe the instructions in the section entitled "Safety".
Operate the device only while it is vertical or suspended upright and nearly vertical.
Avoid allowing drops of spray to drift onto areas that are not being treated.
Observe the instructions of the spray product manufacturer!
1. Hang the device over your shoulder. (Fig. 11)
To prevent dripping, hold the spray wand up when first spraying and activate the shut-
off valve until no more liquid mixed with air is emerging from the nozzle.
