2. If required, reset the lock [40] and activate the shut-o󰀨 valve [9]. (Fig. 14)
► Spraying may now begin.
3. Make certain the optimum spraying pressure is set (→ Table 2) on the pressure gauge
[16] (Fig. 11).
EN ENGLISH
Preparation
+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.
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.
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!
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.
1. Hang the device over your shoulder. (Fig. 13)
Spraying pressure Spray quantity for hollow cone nozzle
1.5 bar (21.8 psi) 0.48 l/min (0.13 gal/min)
2.0 bar (29.0 psi) 0.56 l/min (0.15 gal/min)
3.0 bar (43.5 psi) 0.69 l/min (0.18 gal/min)
Table 2. Dependence: Spraying rate – spraying pressure
+If liquid mixed with air emerges from the nozzle, the tank is empty.
4. If the spraying pressure decreases more than 0.5 bar (7.3 psi) from the optimum level,
pump some more.
