 Take out detergent suck hose.
 By turning the filter the detergent can be
dosed roughly.
Cleaning
 Set pressure/temperature and deter-
gent concentration according to the sur-
face to be cleaned.
Note: To prevent damage due to too much
pressure, always position high pressure ray
first from a greater distance towards object
to be cleaned.
Working with the high pressure nozzle
The spray angle is essential for the effec-
tiveness of the high pressure ray. Normally
work is performed with a 25° flat ray nozzle
(included).
Recommended nozzles are deliverable as
accessories
For strong contaminations
–
0° full ray - nozzle
For sensitive surfaces and light contam-
–
inations
40° flat ray - nozzle
For thick layered, persistent contamina-
–
tions
Dirt grinder
Nozzle with adjustable spray angle, for
–
adaption to different cleaning tasks
Angle-Vario-Nozzle
Recommended cleaning method
Loosen the dirt:
–
 Spray detergent economically and let it
work for 1...5 minutes but do not let it
dry up.
Remove the dirt:
–
 Spray off loosened dirt with the high-
pressure jet.
Operating with cold water
Removal of light contaminations and clear
rinse, i.e.: Gardening tools, terrace, tools,
etc.
 Set operating pressure according to
need.
 Set the appliance switch to "I".
Operating with hot water
Danger
Scalding danger!
 Set device switch to desired tempera-
ture.
We recommend the following cleaning tem-
peratures:
Light contaminations
–
30-50 °C
Contaminations containing protein, i.e.
–
in the food processing industry
max. 60 °C
Vehicle cleaning, machine cleaning
–
60-90 °C
Operating with steam
Only HDS 558.../601.../698.../798...
Danger
Scalding danger! The operating pressure
must not exceed 3,2 MPa (32 bar) when
operating with temperatures above 98 °C.
Therefore the following measures must
definitely be performed:
 Replace high pressure nozzle (stain-
less steel) with steam nozzle (brass,
order see specification).
 Open up the pressure/ quantity regula-
tor on the hand spray gun completely,
direction + until stop.
See Figure 5 (B).
 Set the operating pressure on the appli-
ance to the minimum value.
See Figure 6.
 Set device switch to min. 100 °C.
Danger
Scalding danger!
We recommend the following cleaning tem-
peratures:
De-preserve, contaminations contain-
–
ing strong fat contents
100-110 °C
De-frosting of surcharge substances,
–
partially facade cleaning
up to 140 °C
