IMPORTANT PRECAUTIONS – Read First!
Safety Warnings
When using this product, basic precautions should always be followed:
• Read all the instructions before using
the product.
• 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.
• Wear safety goggles.
• Do not use acids,
solvents, or any
flammable material in this product.
These products can cause physical
injuries to the operator and irreversible
damage to the machine.
• Do not operate the product when
fatigued or under the influence of
alcohol or drugs.
• Keep operating area clear of all
persons.
• Do not stand on unstable surfaces.
Stand with both feet balanced at all
times.
• To reduce the risk of electrocution, keep
all connections dry and off the ground.
Do not touch plug with wet hands.
• The Gun Safety Lock PREVENTS
the trigger from accidentally being
engaged. This safety feature DOES
NOT lock trigger in the on position.
Extension Cords
Use a sufficient gauge: Up to 25 ft = 12/3
AWG; 25 to 50 ft = 10/3 AWG. Use only
extension cords that are intended for
outdoor use. These extension cords are
identified by the marking “Acceptable for
use with outdoor appliances; store indoors
while not in use.” Use only extension
cords having an electrical rating not less
than the rating of the product. Do not use
damaged extension cords. Examine
extension cord before using and replace if
damaged. Do not abuse extension cord
and do not yank on any cord to
disconnect. Keep cord away from heat
and sharp edges. Always disconnect the
extension cord from the receptacle before
disconnecting the product from the
extension cord. If you are using an
extension cord, it should always be
completely unwound from the cable drum.
Ground Fault Circuit
Interrupter (GFCI) Protection
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 reclose 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
replacement parts.
This Product Is
Double Insulated
In a double-insulated product, two
systems of insulation are provided instead
of grounding. No grounding method is
provided on a double-insulated product,
nor should a method for grounding be
added to the product. Servicing a doubleinsulated product requires extreme care
and knowledge of the system, and should
be done only by qualified service
personnel. Replacement parts for a
double-insulated product must be
identical to the parts they replace. A
double-insulated product is marked with
the words, “DOUBLE INSULATED.”
Caution
• Follow the maintenance instructions specified in the manual.
• This machine has been designed
for use with cleaning detergent
supplied or recommended by the
manufacturer. The use of other
cleaning detergents may affect
the operation of the machine and
void the warranty.

CLEANING TIPS
Deck Cleaning
(with or without detergent)
Pre-rinse deck and surrounding area with
fresh water. If using Kärcher Deck and Patio
Cleaner, place detergent suction tube directly into cleaning 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
and Patio Cleaner 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.
House Siding
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher House or Window and
Siding Cleaner, place detergent suction tube
directly into cleaning solution and apply to
surface at low pressure (for best results,
limit your work area to sections of approximately 6 feet and always apply detergent
from bottom to top). Allow Kärcher House or
Window and Siding Cleaner to remain on
surface 1-3 minutes. Do not allow detergent
to dry on surface, if surface appears to be
drying, simply wet down surface with fresh
water. If needed, use special Wash Brush
Attachment to remove stubborn dirt. Rinse
at high pressure from top to bottom in an
even sweeping motion keeping the spray
nozzle approximately 6 inches from the
cleaning surface.
Cement Patios,
Brick and Stone
(with or without detergent)
Pre-rinse cleaning surface with fresh
water. If using Kärcher Deck and Patio
or All Purpose Cleaner, place detergent
suction tube directly into cleaning solution

to dry on surface. If needed, use special
Wash Brush Attachment to remove stubborn
dirt. Rinse at high pressure in a sweeping
motion keeping the spray nozzle approximately 6-8 inches from the cleaning surface

CLEANING TIPS –
continued
Barbecue Grills, Outdoor
Power Equipment &
Gardening Tools
(with or without detergent)
Pre-rinse cleaning surface with fresh water.
If using Kärcher All Purpose Cleaner or
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 experiment with different settings on
the Quattro Nozzle.
Patio & Lawn Furniture
(with or without detergent)
Pre-rinse furniture and surrounding area with
fresh water. If using Kärcher All Purpose
Cleaner, place detergent suction tube directly into cleaning solution and apply to surface
at low pressure. Allow Kärcher All Purpose
Cleaner to remain on surface 1-3 minutes.
Do not allow detergent to dry on surface. If
needed use special Wash Brush Attachment
to remove stubborn dirt. Rinse at high pressure in a sweeping motion keeping the
spray nozzle approximately 3-6 inches from
the cleaning surface. For best results, clean
from top to bottom and from left to right.
Recommendations
• Before cleaning any surface an inconspic-
uous 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.
• While using on surfaces which might come
in contact with food. Flush surfaces with
plenty of drinking water.
