Detergents can only be applied with the black nozzle.

Step 1

Install the black quick-connect

low pressure nozzle for detergent
application at low pressure.

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.

For best results see Cleaning Tips
on pages 8 & 9 for specific 
information on how to clean 
different surfaces.

Always Use Kärcher 
Detergents for Best Results.

Kärcher biodegradable detergents are
specially formulated to protect the
environment and your pressure washer.
The special formula won’t clog the suction
tube filter and will protect the internal parts
of the pressure washer for a longer life.
For Kärcher Detergents, check your
retailer or call:

The following Kärcher detergents 
are available:

• Vehicle Wash

• House Wash

• Degreaser

• Deck Wash

• All Purpose Cleaner

Step 2

Adjust the filter end of the

detergent tube for light (-), or maximum (+)
detergent coverage.

Step 3

Fill a container with Kärcher

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

Caution

Never use:

• Bleach, Chlorine products and other 
corrosive chemicals
• Liquids containing solvents 

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

• Tri-sodium phosphate products
• Ammonia products
• Acid-based products
These chemicals will harm the unit and
will damage the surface being cleaned.
