► Set the desired dosage.
► Turn dosing handle (3) to the right (up to
5 %).
The addition of detergents is increased.
► Turn dosing handle (3) to the left (up to
0 %).
The addition of detergents is reduced.
► If the detergent concentration needs to be
adjusted accurately: Measure and calculate
detergent concentration.
► Soak extremely dirty surfaces with water
before cleaning them.
► Press the spray gun lever and spray the deter‐
gent onto the surface to be cleaned.
► Apply the detergent starting at the bottom and
working up and do not allow to dry.
► Turn the dosing handle to the left as far as it
will go.
Detergent is no longer sucked in.
► Clean surface.
10.6.4
Measuring and calculating the deter‐
gent concentration
For a few detergents, the concentration must be
precisely set. In this case, the water flow rate
and the consumption of detergent must be meas‐
ured.
Calculating the predilution of the detergent in %
If the predilution is not indicated as a % value on
the packaging of the detergent used, it can be
determined as follows:
Ratio value
–
1:1 = 50 %
–
1:2 = 33.3 %
–
1:3 = 25 %
–
1:5 = 16.6 %
–
1:10 = 9 %
Example: Calculation ratio value 1:2.
–
A = 1
–
B = 2
A
x 100 = V
x 100 = 33,3%
( A + B )
1
( 1 + 2 )

Measuring and calculating the detergent concen‐
tration.
► Turn the rotary control to set the working pres‐
sure and water quantity in the + direction up to
the stop.
► Turn the dosing handle for cleaning detergent
to the right as far as it will go.
► Fill the detergent container with cleaning agent
up to the 0.5 liter mark.
► Turn the fan jet nozzle in the direction - up to
the stop.
► Switch on pressure washer.
► Hold the spray gun in an empty collecting con‐
tainer.
► Actuate the spray gun and fill 2 liters into the
collecting container.
► Determine the consumption of detergent
„QR“ from the detergent container.
Calculation of the actual detergent concentration:
QR
Q
x V = K
0000-GXX-9862-A0
–
QR = Quantity of detergent used (in liters).
–
Q = 2 liters.
–
V = Pre-dilution of the cleaning agent (in %).
–
K = Concentration of the cleaning agent..
► If the calculated concentration differs from the
desired one: Reduce dosage at the dosing
handle and repeat measurement and calcula‐
tion.

After finishing work
► Switch off the pressure washer and pull the
mains plug out of the socket.
► If the pressure washer is connected to the
water supply: Turn off water tap.
► Press spray gun trigger.
The water pressure is released.
► Lock spray gun trigger.
► Disconnect pressure washer from the water
supply.
► Remove water hose.
► Remove and clean the nozzle and spray
lance.
► Remove the spray gun and let the remaining
water run out of the spray gun.
