Function:
2. Activate the pump lever [11]. (Fig. 8)
► Increasing pressure is indicated on the pressure gauge [22]. (Figs. 8 and 9)
+
The wheel lock [23] can be used to lock and unlock the lever on the shut-off valve [8].
Locking the lever [23b] prevents unintentional spraying.
3. Unlock the wheel lock [23a] and activate the shut-off valve [8]. (Fig. 9)
► 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.
Preparation
Observe 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
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. 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 is emerging from the nozzle.
3. Ensure that the optimum spraying pressure is set on the pressure gauge [22] (Figs. 8
and 9).
