Intended use

Cleaning of: Machines, vehicles,
buildings, tools, facades, terraces,
garden tools, etc..
* Heed appropriate safety
regulations for use at petrol
stations or in other hazardous
environments.
Please ensure waste water
containing mineral oil
does not contaminate soil, lakes and
rivers or the sewerage system.
Therefore, please wash engines and
underbodies only in appropriate
washing installations provided with
oil traps.
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
HDS 551 C, 558 C, 698 C, 798 C, 558 CSX, 698 CSX, 798 CSX
– 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
– Motor vehicle cleaning, machine
cleaning 60-90°C
Set selector switch to desired
temperature

Operation with steam

(only HDS 558../698../798..)
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
