Making preparations

Observe the instructions in the section entitled "Safety".
The device must be in an upright position.
1. Screw the cover [7] off the tank. (Fig. 4)
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.
2. Pour the spray liquid through the filling strainer [8] into the tank. (Fig. 5)
If filling the tank from a water line, ensure that the line or a hose does not project into
the tank.
3. Check the filling level with the scale [9] on the tank. (Fig. 5)
4. Screw the cover [7] onto the tank. (Fig. 6)
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. 7)
2. Using the lever [10], generate the required pressure (→ Table 2, Fig. 7).
The maximum pressure should not exceed 6 bar (red line on the pressure gauge [11],
Fig. 8). If the max. pressure is exceeded, the function may be affected.
To prevent dripping, hold the spray lance up when first spraying and activate the shut-
off valve until no more liquid mixed with air is emerging.
3. Activate the shut-off valve [6]. (Fig. 8)
Spraying may now begin.

4. Ensure that the optimum spraying pressure (→ Table 2) is set on the pressure gage [11]
(Fig. 8).

Table 2. Dependence: spraying rate and spraying pressure
5. Continue pumping slowly and regularly to maintain a continuous spraying pressure. (Fig. 7)
If liquid mixed with air emerges from the nozzle, the tank is empty. Pump
completely empty after each fifth filling at the latest.
