Adding Detergent - Stihl RE 521 Notice D'emploi

English

Adding detergent

Unscrew cap from detergent
N
container
Fill detergent tank with STIHL
N
detergent diluted as specified –
STIHL recommends using STIHL
detergent
Screw cover with intake hose onto
N
detergent container
The cap has a standard thread and fits
all standard detergent containers.
Use the detergent metering knob to
N
adjust the amount of detergent to be
added – as shown in picture
Detergent metering knob
to the left:
Detergent metering knob
to the right:
52
When applying detergent, start at
N
the bottom and work upwards
To achieve a better result, spray the
detergent on the dry surface and let it sit
for a few minutes.
Detergent must not be allowed to dry on
the object to be cleaned.
Rinse detergent system
If detergent is no longer to be added:
Turn the detergent metering knob to
N
the left as far as it will go to
0 % (min)
Let the high-pressure cleaner
N
continue to run with the spray gun
open until no more detergent comes
out of the nozzle
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.
Set the detergent metering knob to
N
"0" % (min)
Hold the spray gun in a suitable
N
empty receptacle (> 20 l) and
actuate for exactly 1 minute
Measure the quantity of water "Q" in
N
the container
Fill 2 liters of detergent diluted as
N
directed into a suitable container
(with a scale of 0.1 l) – STIHL
0 % (min)
recommends the use of genuine
STIHL detergents
5 % (max)
Hold the intake hose in the
N
container
Set the detergent metering knob to
N
the desired concentration: 0 %
(min) to 5 % (max)
Hold the spray gun in a suitable
N
empty receptacle (> 20 l) and
actuate for exactly 1 minute
Read the detergent consumption
N
"QR" on the scale
Calculating the actual detergent
concentration:
QR
x V = concentration
Q
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:
Ratio
1:1 = 50 %
1:2 = 33.3 %
1:3 = 25 %
1:5 = 16.6 %
1:10 = 9 %
