Checks
Visual inspection: Check that tank [1], pump [2], hose [3], shut-off valve [7], piston
pressure gage [9] and spray wand [6] with nozzle are undamaged.
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 [9] (Fig. 3)
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 button on the piston pressure gauge [9] until all excess pressure is
released from the tank (Fig. 3)
2. Press the piston rod with handle [11] down and turn it counterclockwise
The piston rod with handle is locked. (Fig. 5)
►
3. Unscrew the pump [2] from the tank. (Fig. 6)
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.
4. Add the spraying liquid to the tank [1] (Fig. 7)
5. Check the filling level with the scale [12] on the tank. (Fig. 7)
6. Screw the pump [2] into the tank. (Fig. 8)
7. Press the piston rod with handle [11] down and turn it clockwise.
The piston rod with handle is unlocked. (Fig. 9)
►
8. Generate the desired pressure (→ Table 2) in the tank (Fig. 10).
The maximum pressure should not exceed 3 bar (red line on the piston pressure gauge,
Fig. 10). If the maximum pressure is exceeded, the safety valve will engage and
release the excess pressure.
9. Press the piston rod with handle [11] down and turn it counterclockwise (Fig. 5)
The 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.
2. Activate the shut-off valve [7]. (Fig. 12)
Spraying may now begin.
