Without compressed-air filling valve
8. Press the pump handle [13] down and turn it clockwise.
►The pump handle is unlocked. (Fig. 10).
9. Generate the required pressure (→Table 2) in the tank [1] (Fig. 11).
The maximum pressure should not exceed 6 bar (red line on the pressure gauge [16],
Fig. 11). If the maximum pressure is exceeded, the safety valve will engage and
release the excess pressure.
10. Press the pump handle [13] down and turn it counterclockwise.
►The pump handle is locked in place. (Fig. 5).
With compressed-air filling valve (option)
8. Connect the compressed-air hose [17] to the compressed-air filling valve [18]. (Fig. 12).
►Pressure is built up (max. 6 bar).
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. Suspend the device from your shoulder or place it on your back.
(Fig. 13 and/or 14)
To prevent dripping, hold the spray lance up when first spraying and activate the shut-
off valve until no more liquid mixed with air is emerging.
2. Activate the shut-off valve [9] (Fig. 15).
►Spraying may now begin.
Pressure regulation cannot be adjusted on the shut-off valve
(Device types 3565, 3585, 3595, 3615)
3. Make certain the optimum spraying pressure is set (→Table 2) on the pressure
gauge [16].
Spraying pressure Spray quantity for hollow cone nozzle
1,5 bar (21,8 psi) 0,49 l/min
2,0 bar (29,0 psi) 0,56 l/min
3,0 bar (43,5 psi) 0,69 l/min
Table 2. Dependence: spraying rate and spraying pressure
4. If the spraying pressure decreases more than 0,5 bar (7,3 psi) from the optimum level, pump
some more.
Pressure regulation can be adjusted on the shut-off valve
(Device types 3585G, 3615G)
3. Turn the red "DOSICONTROL" adjusting wheel [20] (Fig. 15) ("+" higher pressure,
"–" lower pressure) and adjust the optimum spraying pressure. (→Table 2, above)
4. Observe the spraying pressure on the pressure gauge [19] (Fig. 15) and readjust if
necessary.
5. If the pressure can no longer be adjusted, pump some more.
If liquid mixed with air emerges from the nozzle, the tank is empty.
