Making preparations
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 handle [14] until the tank is depressurized. (Fig. 4)
2. Unscrew the pump [2] from the tank. (Fig. 5)
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.
If used for HERBICIDES, this spraying device should no longer be used for applying
pesticides.
3. Add the spraying liquid to the tank [1] (Fig. 6)
4. Check the filling level with the scale [15] on the tank. (Fig. 6)
5. Screw the pump [2] into the tank. (Fig. 7)
6. Press the piston rod with handle [16] down and turn it clockwise.
►
The piston rod with handle is unlocked. (Fig. 8)
7. Create the desired pressure (
→
Table 2) in the tank (Fig. 9)
The maximum pressure should not exceed 3 bar (red line on the piston pressure gauge,
Fig. 9). If the maximum pressure is exceeded, the safety valve will engage and release
the excess pressure.
8. Press the piston rod with handle [16] down and turn it clockwise. (Fig. 10)
►
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.
3. Make certain the optimum spraying pressure is set (
→
Table 2) on the piston pressure
gauge [14] (Fig. 10).
Table 2. Dependence: spraying rate and spraying pressure
4. If the spraying pressure decreases more than 0.5 bar from the optimum level, pump
some more.
If liquid mixed with air emerges from the nozzle, the tank is empty.
