GROUND FAULT CIRCUIT
INTERRUPTER PROTECTION
WATER SUPPLY
(Cold Water Only)
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 replacement parts.
SERVICING OF A DOUBLE-
INSULATED PRODUCT
In a double-insulated product, two sys­tems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated product, nor should a means 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 double­insulated product is marked with the words “double-insulation” or “double-in- sulated”. The symbol “” may also be marked on the product.
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 GPM (gallons per minute).
Flow rate can be determined by run-
ning 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 water source.

The Vario Power Spray Wand allows
you to adjust the cleaning pressure. To clean at maximum pressure, the
wand must be positioned to the high pressure setting (Max).
For lower pressure turn the wand collar in the minus (Min) direction. To apply detergent, the wand must be positioned to the lower pressure setting (Min).
Dirtblaster®
This nozzle features a 0º pencil jet
which rotates 360º for maximum dirt cutting action, effectively increasing cleaning performance up to 50%. This nozzle combines the cleaning performance of a 0º pencil jet with the surface coverage of a wide angle nozzle.
Not recommended for soft materi­als, siding, painted surfaces, decks or autos.
Always test an inconspicuous area
before cleaning with the Dirtblaster

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 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 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 1­3 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.
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
vehicle with fresh water. If using Kärch­er Touchless Vehicle Wash, apply to surface at low pressure. For best 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. 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 the cleaning surface (distance should increase when rinsing pin-strip­ing 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.

Barbecue Grills, Outdoor Power
Equipment & Gardening Tools
(with or without detergent). Pre-rinse
cleaning surface with fresh water. If us­ing Kärcher Pressure Wash or Degreas­er, apply detergent at low pressure. Allow Pressure Wash 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.
Patio & Lawn Furniture
(with or without detergent). Pre-rinse
furniture and surrounding area with fresh water. If using Pressure Wash, ap­ply to surface at low pressure. Allow Pressure Wash to remain on surface 1­3 minutes. 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 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 in-
conspicuous area should be cleaned
to test spray pattern and distance for
maximum cleaning results.
If painted surfaces are peeling or
chipping, 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 sur-
faces with plenty of drinking water.
