Fitting, removing detergent tank
The detergent tank can be removed
from the machine e. g. to empty or clean
it.
N
Unscrew the cap with intake hose
from the detergent tank
N
Hold the detergent tank by the
handle and pull it up and back out of
the holder
N
if necessary, remove the closed cap
on the rear of the tank and screw it
onto the filling opening of the
detergent tank
N
To fit the detergent tank, push it into
the opening and use the handle to
push it against the frame until it
engages
The intake hose can be pushed into the
high-pressure cleaner housing for
storage.
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:
647BA012 KN
647BA013 KN
QR
x V = concentration
