Visual inspection:
1. Are tank [2], hose [6], shut-o󰀨 valve [8] with pressure gauge [22] and spray wand [7]
with nozzle [41] undamaged?
+Pay special attention to the connections between the tank [17] – hose [6] and the
hose [6] – shut-o valve [8] and to the condition of the spray wand [7].
1. Fasten the carrying strap [1] to the tank. Secure it with the metal pin [12]. (Fig. 2)
2. Attach the eyes [13] on the carrying strap [1] to both sides of the tank.
3. Attach the back cushion [9] to the tank using 2 bolts (outside) and 2 nuts with washers
(inside) [2]. (Figs. 2 and 3)
4. Press the 2 nuts [14] into the carrying handle [3] (for 18 liter devices only).
Insert the carrying handle and screw tight with the 2 screws [15] in the tank [2]. (Fig. 3)
5. Feed the hose [6] through the opening in the lower part of the tank as well as between
the shaft [16] and tank base. Push the hose all the way onto the connecting piece [17].
Tighten the union nut to secure the hose. (Fig. 4)
6. Push the hose [6] all the way onto the connecting piece of the shut-o󰀨 valve [8]. Tighten
the union nut to secure the hose. (Fig. 4)
7. Screw the spray wand [7] onto the shut-o󰀨 valve [8]. (Fig. 4)
8. Turn the shaft [16] clockwise until it engages. Insert the pump lever [10] to the required
depth into the shaft [16] (3 positions). (Fig. 5)
+Pump lever [10] with handle can be tted on the left or right.
9. Secure the pump lever [10] in the shaft using the retaining clip [18]. (Fig. 5)

Preparation
Spraying
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 pres-
sure relief valve will actuate and release the excess pressure from the pressure vessel.
1. Screw the cover [19] o󰀨 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 ll up
with water.
2. Pour the spray liquid through the lling strainer [21] into the tank. (Fig. 7)
+In the case of 18 liter devices the maximum lling quantity is reached as soon as the
liquid level can be seen in the lling strainer.
3. Screw the cover [19] onto the tank. (Fig. 6)

3. Ensure that the optimum spraying pressure is set on the pressure gauge [22] (Figs. 8 and 9).
EN ENGLISH
To prevent dripping, hold the spray wand up when rst spraying and activate
the shut-o valve until no more liquid mixed with air is emerging from the
nozzle.
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!
Check the device regularly and after a longer period of non-use, e.g. a winter break.
Have damaged parts or parts that do not work properly repaired immediately by our
customer service department or by service partners authorized by us.
Observe the instructions in the section entitled „Safety“.
The device must be in an upright position.
If lling the tank from a water line, ensure that the line or a hose does not project
into the tank.
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-o valve [8].
Locking the lever [23b] prevents unintentional spraying.
3. Unlock the wheel lock [23a] and activate the shut-o󰀨 valve [8]. (Fig. 9)
► The shut-o󰀨 valve must open and close.
