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 other
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.
• 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 = 12/2
AWG; 25 to 50 ft = 10/2 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 Protection
To comply with the National Electrical
Code (NFPA70) and to provide additional
protection from the risk of electrocution,
this high pressure washer should only be
connected to a receptacle that is protected by a ground fault circuit interrupter
(GFCI). For best results, unit should be
plugged into an unshared outlet.
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 double-insulated 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.
3
Water Supply
(Cold Water Only)
• Water hose must be at least 3/4 inch in
diameter.
• Flow rate of water supply must not fall
below 2.5 GPM (gallons per minute).
• Flow rate can be determined by running
the water for one minute into an empty
5-gallon container.
IMPORTANT PRECAUTIONS –
continued
• The water supply temperature must not
exceed 104°F/40°C.
• Never use the pressure washer to draw in
water contaminated with solvents, e.g.
paint thinners, gasoline, oil, etc.
• Always prevent debris from being drawn
into the unit by using a clean water source.

USING THE ACCESSORIES
5
The pressure washer has two fully automatic pressure settings, depending on the wand or
nozzle installed.
This wand features a 0º pencil jet which
rotates 360º for maximum dirt cutting
action, effectively increasing cleaning performance up to 50%. This wand combines
the cleaning performance of a 0º pencil jet
with the surface coverage of a wide angle
nozzle. Use extreme caution when clean-
ing decks, siding, and other sensitive
surfaces as the rotating spray wand may
cause damage if not used correctly.
Rotating spray wand
This nozzle attaches directly to the spray
wand extension and is used to apply detergents to the work area.

CLEANING TIPS
Deck Cleaning
(with or without detergent)
Pre-rinse deck and surrounding area with
fresh water. If using Kärcher Deck Wash,
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
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 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 Wash, 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 Karcher House Wash 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. 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 Karcher All Purpose 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 All Purpose
Cleaner to remain on surface 1-3 minutes.

Rinse at high pressure in a 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.
Cars, Boats & Motorcycles

results, clean one side of vehicle at a time
and always apply detergent from bottom to
top, do not allow detergent to dry on surface. Rinse at high pressure in a sweeping
motion keeping the spray nozzle approximately 8 inches from the cleaning surface
(distance should increase when rinsing pinstriping or other sensitive surfaces). Always
clean from top to bottom and from left to
right. For best results, wipe surface dry with
a chamois or soft dry cloth.

nozzle approximately 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.
