Always Use Karcher 
Detergents for Best Results.

Karcher biodegradable detergents are
specially formulated to protect the environ-
ment and your pressure washer. Special 
formula won’t clog the suction tube filter 
and will protect the internal parts of the
pressure washer for a longer life. For
Karcher Detergents, check your retailer

The following Karcher detergents are
available:

Install the Vario spray wand and

set the Vario spray wand to the low pres-
sure setting (-) by turning the wand collar.
The wand must be set in the low pressure 
(-) position to apply detergents.

Fill a container with Karcher

detergent. Place the filter end of detergent
suction tube into the container.

With the engine running, pull 

trigger to operate unit: Liquid detergent is
drawn into the unit and mixed with water.
Apply detergent to work area. Do not allow
detergent to dry on surface.

corrosive chemicals

• Liquids containing solvents 

(i.e., paint thinners, gasoline, oils)
