Operating pressure and flow rate
can be set at handgun.
Set pressure on unit if use is to be
made of reduced pressure for a
lengthy period. See Fig. 8
Measuring out the cleaning agent
*
Use cleaning agents sparingly to
protect the environment
*
The cleaning agent must be
suitable for the surface to be
cleaned.

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
*
To avoid damage from excessive
pressure, always direct the high-
pressure stream onto the object to
be cleaned from a sufficient
distance away.
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
