4. Oil change

!
Danger!
Risk of getting burnt from hot oil and hot
system components. Let pump cool down
for 15 minutes before making oil change.
Important!
Used oil may be disposed of only at the
collecting points designated for this purpo-
se. Please hand in used oil resulting from
the oil change at such a place. Pollution of
the environment with waste oil is a punisha-
ble offence.
Oil types and oil quantities: see Technical
Data.

5. Decalcification

!
Danger!
Explosion hazard through flammable gases!
Smoking is prohibited when carrying out
decalcification procedures. Ensure adequa-
te ventilation.
Caution!
Acid hazard!
Protective goggles and gloves must be
worn.
Lime deposits throughout the water lines of
the high-pressure system create increased
pipe-run resistance and may result in the
failure of calcified components.
According to official regulations, only ap-
proved boiler scale dissolvants (de-scaling
acid) with test mark may be used.
For scale removal in the high-pressure sy-
stem, the use of KÄRCHER scale dissol-
vants should be given preference
(RM 100 ASF, hydrochloric acid-free, part
no. 6.287-008, or RM 101 ASF, containing
hydrochloric acid, part no. 6.287-013).
These products are balanced for use in
conjunction with the materials present
throughout the system. After decalcification
we recommend neutralising the remaining
acid residues by flushing the system with
an alkaline solution (pH value 7–8).
The instructions for use and accident pre-
vention regulations (dilution according to la-
bel specifications), and in particular VBG1,
§4, 14, and 44–47 must be observed.
