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. Pull up the red piston pressure gauge [16] until the tank is depressurized. (Fig. 5)
2. Press the piston rod with handle [13] down and turn it counterclockwise.
► The piston rod with handle is locked. (Fig. 6)
3. Unscrew the pump [2] from the tank. (Fig. 7)
4. Add the liquid to the tank [1]. (Fig. 8)
5. Where appropriate, add cleaning agent.
6. Check the filling level with the scale [35] on the tank. (Fig. 8)
7. Screw the pump [2] into the tank. (Fig. 9)
8. Press the piston rod with handle [13] down and turn out of the lock.
► The piston rod with handle is unlocked. (Fig. 10)
9. Generate the desired pressure in the tank (Fig. 11).
+
The maximum pressure should not exceed 3 bar (red line on the piston pressure
gauge, Fig. 11). If the maximum pressure is exceeded, the safety valve will engage
and release the excess pressure.
10. Press the piston rod with handle [13] down and turn into the lock. (Fig. 6)
► The piston rod with handle is locked.
Foaming
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. 13)
2. Align the foam nozzle to the area to be sprayed with a distance of 50 / 70 cm.
3. If required, reset the wheel lock [40] and activate the shut-off valve [9]. (Fig. 12a)
► Spraying may now begin.
4. Make certain the optimum spraying pressure is set on the piston pressure gauge [16]
(Fig. 11).
+
The foaming result may be influenced considerably by the pressure, the type of
fleece pad fitted in the nozzle and the applied foaming agent.
5. Release the lever of the shut-off valve [9]. (Fig. 14)
► Spraying ends.
6. In case the foam width becomes increasingly smaller, pump some more.
