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

–
Slight contamination 86-122°F
–
Protein soiling, e.g. in foodstuffs
industry max. 140°F
–
Motor vehicle cleaning, machine
cleaning 140-194°F
Set selector switch to desired
temperature
AFTER EVERY OPERATION
Following operation with cleaning

drained off completely!
Store unit in a frost-free location
Take unit out of service if frost-free
storage is not possible.
SHUTTING DOWN
In the event of lengthy periods of
non-use or if frost-free storage is not
possible:
–
Drain unit or flush with anti-freeze
–
Drain cleaning fluid tank
Draining unit
–
Unscrew water supply hose and
high-pressure hose
–
Unscrew supply line at boiler base
and allow heating coil to drain
–
Run unit for max. 1 min until pump
and lines are empty
Flushing unit with anti-freeze
–
Use commercial grade antifreeze
–
Observe handling instructions of
antifreeze manufacturer
–
By this means, a certain degree of
corrosion protection is achieved.
