Intended use
Cleaning of: Machines, vehicles,
buildings, tools, facades, terraces,
garden tools, etc..
* Engine cleaning is only to be
performed in areas provided with
oil separator.
* Heed appropriate safety
regulations for use at petrol
stations or in other hazardous
environments.
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 dirt
blaster
– Nozzle with variable spray angle,
for adaptation to various cleaning
tasks variable-angle nozzle
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. 8
– 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
