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.
