Working with high-pressure
nozzle
Spray angle is crucial to efficiency of
high-pressure jet.
Use is normally made of 25°fan jet
nozzle (included).
Recommended nozzles, available as
accessories
–
For stubborn dirt
0°full jet nozzle
–
For delicate surfaces and slight
contamination
40°fan jet nozzle
–
For thick layers of stubborn dirt

Cleaning
*
Set pressure/temperature and
cleaning-agent concentration in
line with surface to be cleaned
*
Always start by directing high-
pressure jet from a good distance
at object to be cleaned to avoid
damage caused by excessive
pressure.
Recommended cleaning method
Loosen up dirt:
Spray on cleaning agent sparingly
and allow to react for 1...5 min (do
not allow to dry on).
Remove dirt:
Spray off loosened-up dirt with high-
pressure jet.
Operation with cold water
Removal of slight contamination and
rinsing
e.g.: Garden implements, terrace,
tools, etc.
Set operating pressure as required
Set selector switch to "I"
Operation with hot water
*
Danger of scalding
We recommend the following
cleaning temperatures
–
Slight contamination 30-50°C
–
Protein soiling, e.g. in foodstuffs
industry max. 60°C
–
Motor vehicle cleaning, machine
cleaning 60-90°C
Set selector switch to desired
temperature
Operation with steam
At operating temperatures above
98°C operating pressure must not
exceed 32 bar.
Standard high-pressure nozzle is
therefore to be replaced with
steam nozzle (part no.: 4.766-023,
see accessories).
–
Set operating pressure to
minimum value. See Fig. 9
–
Set temperature regulator to
min. 100°C
*
Danger of scalding!
We recommend the following
cleaning temperatures
–
Preservative removal, extremely
greasy dirt 100-110°C
–
Thawing of aggregates, certain
facade cleaning operations up to
140°C
EACH TIME AFTER USAGE
Warning!
Danger of scalding with hot water.
After operating it with hot water or
steam the unit must be cooled for at
least two minutes by operating it
with cold water and its open
handgun.
Following operation with cleaning
agent
–
Set cleaning-agent regulator to "0"
–
Set mode selector switch to "I"
–
Actuate handgun and flush unit for
approx. 1 min
Stopping machine
–
Set mode selector switch to "0"
–
Shut off water supply
–
Briefly (approx. 5 sec.) switch on
pump with selector switch
–
Remove mains plug from socket
ONLY with dry hands
