 Danger
– The explosion protection must be taken
into consideration when operating with
solvents as well as in EX zones!
– Maximum pressure with solvent opera-
tion: 5 MPa
– Maximum flow volume with solvent op-
eration: 50 l/min
Caution
When operating with solvents, the sealing
materials are less resistent, therefore they
must be flushed immediately after use! En-
quire with Kärcher!
1 Hydrocarbons
Example: Petroleum
2 Aromates (solvents)
Example: Benzene, toluene
3 Ketones
Example: MEK (Methyle Ethyle Ke-
tones), Acetone
4 Ester
Example: Butylacetate, Methylacetate
5 Glycoles
Example: Butyl glycole
6 Mixed solvents
Example: Butyl acetate 85, Isobutyl ac-
etate 85 (85 = 85% Butyl acetate + 15%
n-Butanol)
7 Regenerates, distillates from different
solvents, which have already been
used for cleaning purposes or similar
applications.
1 Water with alkaline cleaning agents
(max. 0-2%)
Example: Kärcher cleaning agents
RM31
2 Caustic soda max. 10%, without hy-
pochlorite particles
3 Potassium hydroxide max. 10%, with-
out hypochlorite particles
Caution
– The material will be worn off faster
when using hydrochloric or sulfuric ac-
ids; therefore it must be rinsed/neutral-
ised immediately!
– Contaminated acids will decrease the
resilience!
– Enquire with Kärcher if needed!
1 Water with acid cleaning agents (max.
0-1%)
Example: Kärcher cleaning agents
RM25
2 Acids (max. temperature +20 °C)
Nitric acid max. 10%.
Acetic acid max. 10%.
Formic acid max. 10%.
Phosphoric acid max. 10%.
Citric acid max. 10%.
Sulfuric acid max. 0.5%.
Hydrochloric acid max. 0.5%.
1 Water
2 Fully desalted water
If other cleaning liquids are used, their resil-
ience must be checked by means of the
materials list! These cleaning liquids can
only be used after being released by Kärch-
er!
