Preparation
Follow the instructions in the section entitled "Safety".
The device must be in an upright position.
If filling the tank from a water line, ensure that the line or a hose does not
project into the tank.
1. Screw the cover [19] off the tank. (Fig. 6)
Measuring cups [20] are integrated in the cover [19] and can be used to prepare
the spraying agent. Fill the tank 1/3 with water, pour in the spraying agent and
then fill up with water.
2. Pour the spray liquid through the filling strainer [21] into the tank. (Fig. 7)
In the case of 18 liter devices the maximum filling quantity is reached as soon as
the liquid level can be seen in the filling strainer.
3. Screw the cover [19] onto the tank. (Fig. 6)
Spraying
Follow 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.
Follow the instructions of the spray product manufacturer!
1. Place the device on its back. (Fig. 8)
2. Using the pump lever [11], pump slowly and regularly to maintain a continuous
spraying pressure. (→ Table 2, Fig. 8)
Max. pressure should not exceed 6 bar. If the maximum pressure is exceeded, the
pressure relief valve will actuate and release the excess pressure from the
pressure vessel.
To prevent dripping, hold the spray wand up when first spraying and activate the
shut-off valve until no more liquid mixed with air comes out of the nozzle.
3. Ensure that the optimum spraying pressure is set on the pressure gauge [22] (Figs.
8 and 9).
