the skin. do not point the gun at anyone or any part of the body. In case of penetration seek medical aid immediately. This system is capable of producing 12400 kPa /1800 PSI to avoid rupture and injury, do not operate this pump with components rated less than 12400 kPa /1800 PSI working pressure (including but not limited to spray guns, hose and hose connections). Before servicing, cleaning or removing any parts, shut off power and relieve pressure.
This product must be grounded. If it should malfunction or breakdown, grounding provides 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 codes and ordinances.
DANGER
Improper connection of the equipmentgrounding conductor can result in a risk of electrocution. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use any type of adapter with this product.
This pressure washer is provided with a ground-fault circuit-interrupter (GF-
CI) built into the plug of the power-sup- ply cord. This device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.
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.
Flow rate can be determined by running the water for one minute into an empty 5-gallon container.

USING THE ACCESSORIES
WARNING
To avoid serious injury never point spray nozzle at yourself, other persons or animals.
Always test an inconspicuous area before cleaning with high pressure.
Vario Power Spray Wand
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.
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.
Before cleaning any surface an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.
To apply detergent, the wand must be positioned to the lower pressure setting (Mix).
WORKING WITH DETERGENTS
Detergents can only be applied at low pressure setting (Mix).
STEP 1:
Install the Vario Power Spray Wand. Set the spray wand to the low pressure setting (Mix).
STEP 2:
Fill the detergent tank with Karcher detergent and position the tank into its storage area. Insert the suction tube with filter into the tank and close it with the cap.
English 11
STEP 5: |
Always Use Kärcher® Detergent for
Best Results
Kärcher® biodegradable detergents are specially formulated to protect the environment and your pressure washer. The special formula won’t clog the suction tube filter and will protect the internal parts of the pressure washer for a longer life. For Kärcher® Detergents, check your retailer or visit our website:
CAUTION
–Bleach, Chlorine products and other corrosive chemicals
–Liquids containing solvents (i.e., paint thinners, gasoline, oils)
–Tri-sodium phosphate products

Pull out water inlet filter with flatnose pliers.
14 English
CAUTION
(with or without detergent). Pre-rinse deck and surrounding area with fresh water. If using detergent, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow detergent 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.
(with or without detergent). Pre-rinse cleaning surface with fresh water. If us-
ing detergent, 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 detergent 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.
(with or without detergent). Pre-rinse cleaning surface with fresh water. If using detergent or Degreaser, apply to surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow detergent 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.
(with or without detergent). Pre-rinse vehicle with fresh water. If using detergent, 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,
English 15
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 detergent or Degreaser, apply detergent at low pressure. Allow 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.
(with or without detergent). Pre-rinse furniture and surrounding area with fresh water. If using detergent, apply to surface at low pressure. Allow detergent to remain on surface 1-3 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.

For example, insert the cleaning nozzle in the base of a downspout, pull the trigger on the pressure washer gun and watch as the nozzle shoots out leaves and other debris while climbing upward. Connects directly to the trigger gun of most Kärcher® pressure washers up to 2300 PSI. (bayonet)
Why spend hours stripping old paint and rust by hand using harsh chemicals? Let the Kärcher® Wet Sandblasting Kit do the work! Attach the kit to your pressure washer, add abrasive
English 17

When you finish cleaning the patio and driveway, remove the wand and use the handle to clean garage doors and other vertical surfaces. Includes two nozzles which spin at high speed for optimum results. Our top selling accessory for Kärcher® pressure washers up to 2300 PSI. (bayonet)
