Protection from sub-zero
temperatures
Caution!
Water which has frozen in the cleaner
can destroy parts of it. At best store
the cleaner in a heated room during
the winter or empty it or rinse it
thoroughly with antifreeze.
Empty the cleaner
– Unscrew supply hose and high-pres-
sure hose from the cleaner.
– Leave the cleaner running until
the pump and lines have emptied
(max. 1 minute).
Putting in antifreeze
For longer intervals between operations,
pumping antifreeze through the cleaner
is to be recommended. By this means
also you obtain a sure protection against
corrosion.
Care and maintenance
Danger!
Before undertaking any care or main-
tenance work on the cleaner, pull out
the power plug.
Caution!
When changing the oil, dispose of
any waste oil only at authorised
collection points.
Safety inspection/
maintenance contract
You can arrange with your dealer to have
a regular safety inspection carried out or to
have a maintenance contract. Please seek
advice on this.
Each time before operating
the cleaner
Check connecting cable for damage
(risk of getting an electric shock), have
a damaged connecting cable replaced
without delay by authorised Customer
Service personnel or an electrician.
Check high-pressure hose for damage
(danger of explosion), replace
a damaged high-pressure hose
without delay.
Check cleaner (pump) for any leaks.
3 Three drops per minute are allowable
and can appear on the underside of the
cleaner. Seek the help of Customer
Service if leaks are more serious.
Every week
Check oil level in oil reservoir: if the oil is
milky (water in oil), seek the help of
Customer Service immediately.
Clean the strainer at the water outlet.
Clean the filter at the suction hose for
detergent.
Annually or after
500 operating hours
Change the oil
– For oil quantity and type see
Technical Specifications.
