N
Set the detergent metering knob to
0 % (min)
N
Let the high-pressure cleaner
continue to run with the spray gun
open until no more detergent comes
out of the nozzle
N
see “Switching off the machine”
Transport
To prevent spillage of detergent during
transport:
N
Unscrew the cap with intake hose
from the detergent tank
N
Clip the intake hose into the groove
and engage the cap in the holder
N
Close the tank using the closed cap
Using detergent from a separate
container
N
Unscrew the cap with intake hose
from the detergent tank
N
Seal the filling opening of the
detergent tank with the closed cap
N
Screw the cap with intake hose onto
a separate detergent container
The cap has a standard thread and fits
all standard detergent containers.
N
Slide the intake hose as far as
possible into the detergent
container
Precisely calculating/setting the
detergent concentration
For a few detergents, the concentration
must be very precisely set. In this case,
measure the water flow and detergent
consumption.
N
Set the nozzle sleeve to low-
pressure operation – as described
above
N
Set the detergent metering knob to
"0 % (min)"
N
Hold the spray gun in a suitable
empty receptacle (> 20 l) and
actuate for exactly 1 minute
N
Measure the quantity of water "Q" in
the container
N
Fill 2 liters of detergent diluted as
directed into a suitable container
(with a scale of 0.1 l) – STIHL
recommends the use of genuine
STIHL detergents
N
Hold the intake hose in the
container
N
Set the detergent metering knob to
the desired concentration: 0 %
(min) to 5 % (max)
N
Hold the spray gun in a suitable
empty receptacle (> 20 l) and
actuate for exactly 1 minute
N
Read the detergent consumption
"QR" on the scale
Calculating the actual detergent
concentration:
–
QR = Amount of consumed
detergent (in l/min)
–
Q = Water without detergent
(in l/min)
–
V = Predilution of detergent (in %)
If the actual concentration deviates from
the desired concentration, reset knob
and repeat measurement if necessary.
Calculating the predilution of the
detergent in %
If the predilution is not indicated as a
percentage, it can be calculated using
the following table:
Example:
Calculation ratio of 1:2
–
A = 1
–
B = 2
671BA011 KN
QR
x V = concentration
Q
Ratio
1:1
= 50 %
1:2 = 33.3 %
1:3 = 25 %
1:5 = 16.6 %
1:10 = 9 %
A
x 100 = value in %
(A + B)
1
x 100 = 33.3 %
