3. Cleaning agents
Solvents
Hazard!
Hazard (explosive atmosphere) protection is to
observed both for use with solvents and in
hazardous areas!
Maximum pressure for use with solvents: 50 bar
Caution!
Using solvents as cleaning liquids reduces the
resistance of the sealing materials, therefore
rinse immediately after use! Contact Kärcher if
you have any questions!
