Follow the maintenance instructions
specified in the manual.
WARNING
Risk of Injection or Injury – Do Not Direct Discharge Stream At Persons.
High pressure jets can be dangerous if
misused. The jet must not be directed at
persons, animals, electrical devices, or
the unit itself.
Do not spray electrical connections,
electrical outlets or fixtures.
WARNING
Risk Of Explosion – Do not spray flammable liquids.
Do not use acids, alkaline, solvents, or
any flammable material in this product.
These products can cause physical in-
juries to the operator and irreversible
damage to the machine.
WARNING
Gun Kicks Back – Hold with both hands.
The Trigger Gun Safety Lock prevents
the trigger from accidentally being engaged. This safety feature DOES NOT
lock trigger in the ON position.
CAUTION
Risk of Asphyxiation – Use this product only
in a well ventilated area.
Operate and fuel machine in a well ven-
tilated area, free of devices featuring an
open pilot or flame such as boilers, water heaters, etc.
CAUTION
Risk of Fire – Do not add fuel when the
product is operating.
Do not operate if fuel has been spilled.
Instead, move the machine to a different location and avoid creating sparks.
Do not remove the gas tank cap or add
fuel while the engine is running or hot.
Add fuel after the engine has cooled by
waiting 2 or more minutes after the engine is stopped.
Do not smoke when adding fuel
Do not allow the high pressure hose to
come into contact with the muffler
guard.
Do not leave the machine running unat-
tended.
Avoid tipping the machine on its side.
Do not operate the machine with the
muffler or the air cleaner removed. Especially for the muffler, check the tightness of mounting screw, damage and
leakage periodically, and if abnormality
is found, repair or replace it.
Occasionally inspect the fuel system
componets to check for cracks and
leaks. Replace components when necessary.
4 English
WARNING
Do not check for spark with the spark
plug removed.
Do not touch the high-voltage cord or
spark plug cap.
Do not stop the machine by using the
choke lever.
Do not unreasonably adjust the engine

from around the cooling fins and recoil
starter.
Allways use new gasoline. Old gasoline
could cause build up in the carburetor
which could cause poor engine opera-
tion.
SAVE THESE INSTRUCTIONS
WATER SUPPLY
(Cold Water Only)
CAUTION
When connecting the water inlet to the
water supply mains, local regulations of
your water company must be observed.
In some areas the unit must not be connected directly to the public drinking water supply. This is to ensure that there is
no feedback of chemicals into the water
supply. Direct connection via a receiver
tank or backflow preventer, for example, is permitted.
Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.
Garden hose must be at least 5/8 inch in
diameter.
Flow rate of water supply must not fall
below 2.8 GPM (gallons per minute).
Flow rate can be determined by running
the water for one minute into an empty
5-gallon container.
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 wa-
ter source. Use additional water filter.
Do not operate pressure washer without
the water turned on.

CLEANING TIPS
Deck Cleaning
(with or without detergent). Pre-rinse
deck and surrounding area with fresh water. If using Kärcher Deck Wash, apply to
surface at low pressure. For best results,
limit your work area to smaller sections of
approximately 25 square feet. Allow 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 36 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.
몇 CAUTION
Do not use Dirtblaster spray nozzle on
wood surface as it may cause damage.
House Siding
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If using
Kärcher Pressure Wash, 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 Pressure 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. If needed, use special wash
brush attachment (not included) 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.
몇 CAUTION
Do not use Dirtblaster spray nozzle on
siding as it may cause damage.
Cement Patios, Brick and Stone
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If using
Kärcher Pressure Wash or Degreaser, apply to surface at low pressure. For best results, limit your work area to smaller
sections of approximately 25 square feet.
Allow Pressure Wash or Degreaser to remain on surface 1-3 minutes. Do not allow
detergent to dry on surface. 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. For removing extremely stubborn stains, use the Dirtblaster Nozzle.
Cars, Boats & Motorcycles
(with or without detergent). Pre-rinse ve-
hicle with fresh water. If using Kärcher
Touchless Vehicle Wash, apply to surface

side of vehicle at a time and always apply
detergent from bottom to top, do not allow
detergent to dry on surface. If needed, use
special wash brush attachment (not included) to remove stubborn dirt. Rinse at high
pressure in a sweeping motion keeping the
spray nozzle approximately 6-8 inches from

몇 CAUTION
Do not use Dirtblaster spray nozzle on
patio or lawn furniture as it may cause
damage.
Recommendations
Before cleaning any surface an incon-
spicuous area should be cleaned to test
spray pattern and distance for maxi-
mum cleaning results.
If painted surfaces are peeling or chip-
ping, use extreme caution as pressure
washer may remove the loose paint
from the surface.
When using on surfaces which might
come in contact with food, flush surfac-
es with plenty of drinking water.
