First pour in 1/3 of the water, add the spray 

medium and then top up with the remaining 

water. The screw cap can be used to measu-

re the spray substance (Figure 6). 

• Screw down the screw cap into the tank as 

far as it will go 

(Figure 7).

• Release the pump handle by pushing down-

wards and then turning to the right. 

(Figure 8).

• Generate pressure in the tank, max. 3 bar 

(red line on the piston-type pressure gauge, 

Figure 9). The safety valve integrated into 

the piston-type pressure gauge prevents 

excess pressure build-up.

• Lock the pump handle 

(Figure 10)

.

• 

Figure 11 

shows the relationship between 

pressure and flow rate for the standard 

nozzle supplied with the sprayer.

Recommendation for mixing the spray liquid.

9 Maintenance and Care  

(Figure 19 - 24)

After using 50 times, carry out the following 

at least once per year:

We are happy to provide you with test recom-

mendations.

7 Use 

(Figure 12 - 13)

• Before use press discharge valve and hold 

spray lance vertically upright to let air out of 

disharge equipment. This will assure perfect 

operation of sprayer.

• See Figure 12a or 12b for options on how to 

carry your sprayer.

• Make sure you have the correct spray pres-

sure (1.5 – 2.5 bar) 

(Figure 11).

• Squeeze the lever on the discharge valve to 

start spraying 

(Figure 13).

8 Nach Gebrauch

 (Figure 14 - 18)

 

Always empty sprayer after use! 

• Do not dispose of residual liquid down the 

drain (Figure 14).

  Dilute the residual spray medium twice 

using 1/2 liter of water each time. Spray this 

liquid onto the surface being treated.

  Dispose of excess environmentally harmful 

substances as hazardous waste. Observe 

the information issued by the spray medium 

manufacturer.

• Depressurize. Pull up the knob from the 

safety valve until air stops blowing 

(Figure 

15).

• Now remove the screw cap from the tank 

and place it in the holder 

(Figure 16 - 17).

• Wipe the sprayer with a damp cloth.
• Wash protective clothing and hands after
