Using detergent from a separate
container
N Pull out the detergent tank
N Unscrew the cap with intake hose
from the detergent tank
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
After finishing work
N Empty the detergent tank and rinse
it out with clean water
N Immerse the intake hose in clean
water
N Actuate the spray gun and flush out
the residual detergent
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 Pour 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
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 %
(1 + 2)
