Safety Warnings  
When using this product, basic precautions  
should always be followed:  
GROUND FAULT CIRCUIT  
INTERRUPTER (GFCI) PROTECTION  
Read all the instructions before using the  
product.  
This product is supplied with a Ground Fault  
Circuit Interrupter (GFCI) built into the power  
cord plug.This device provides additional  
protection from the risk of electric shock. If  
power is interrupted in the line, the GFCI will  
automatically re-close the circuit to the load  
after power is restored. Depending on the  
GFCI model, it may be necessary to manually  
operate the reset button to restore power to  
the GFCI load circuit. If replacement of the  
plug or cord is needed use identical  
High pressure jets can be dangerous if  
subject to misuse. The jet must not be  
directed at persons, animals, electrical  
devices, or the machine itself.  
To reduce the risk of injury, do not  
operate the machine near children.  
Learn how to stop the machine and  
release pressure quickly. Be thoroughly  
familiar with the controls.  
Stay alert — watch what you are doing.

a path of least resistance for electric current  
to reduce the risk of electric shock.This  
product is equipped with a cord having an  
equipment-grounding conductor and a  
grounding plug.The plug must be plugged into  
an appropriate outlet that is properly installed  
and grounded in accordance with all local

(with or without detergent)  
Pre-rinse deck and surrounding area with fresh  
water. If using Kärcher Deck Wash, place

solution and apply to surface at low pressure.  
For best results, limit your work area to smaller  
sections of approximately 25 square feet.  
Allow Kärcher Deck Wash to remain on  
surface 1-3 minutes. Do not allow detergent to  
dry on surface. Rinse at high pressure in a  
long sweeping motion keeping the spray  
nozzle approximately 3-6 inches from the  
cleaning surface. Always clean from top to  
bottom and from left to right. When moving on  
to a new section of the cleaning surface, be  
sure to overlap the previous section to  
eliminate stop marks and ensure a more even  
cleaning result.

Degreaser, place detergent suction tube  
directly into cleaning solution and apply  
detergent at low pressure. Allow Kärcher  
detergent to remain on surface 1-3 minutes.  
Do not allow detergent to dry on surface.  
Rinse at high pressure keeping the spray  
nozzle approximately 3-6 inches from the  
cleaning surface. For removing extremely  
stubborn dirt, it may be necessary to move  
the spray nozzle even closer to the surface  
for greater dirt cutting action. To remove  
caked on mud from garbage cans, lawn  
mower blades, wheel barrels or other  
non-sensitive metal surfaces, you may want  
to use the Karcher Rotating Nozzle Spray  
Wand.  
Caution: Do not use rotating nozzle  
spray wand on patio or lawn furniture  
as it may cause damage.  
Recommendations  
Caution: Do not use rotating nozzle  
spray wand on cloth, plastic or other  
sensitive surfaces as it may cause  
damage.  
Before cleaning any surface an  
inconspicuous area should be cleaned to  
test spray pattern and distance for  
maximum cleaning results.

If painted surfaces are pealing or chipping,  
use extreme caution as pressure washer  
may remove the loose paint from the  
surface.
