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

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.
