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.
Use a water filter to avoid potential damage from dirt in the water supply

• The Garden hose must be at least 5/8 inch (16 mm) in diameter.
• Flow rate of the water supply must not fall below 2 GPM/gallons per minute (7.6 L/min).
• Flow rate can be determined by running the water for one minute into an empty 5-gallon (18.9 liter) 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.

Using the Accessories

WARNING
To avoid serious injury, never point spray nozzle at yourself, other persons or animals.
CAUTION
Always test an inconspicuous area before cleaning with high pressure.
Using the Nozzles
Each of the nozzles has a different spray pattern. Before starting any cleaning job, determine the best nozzle for the job.
The Turbo Nozzle rotates in a zero degree spray pattern in a circular motion to break down tough dirt and grime. The spray pattern can cover an area of 4 to 8 inches (10 to 20 cm), depending on the distance between the tip and the surface being cleaned.
The 40° Nozzle is efficient for general purpose cleaning. Use to remove loose dirt and grime from most surfaces including cars, wood decks, patios, outdoor furniture, home siding and lawn & garden equipment.
The 15° Nozzle is optimized for concentrated cleaning power and time. Use to remove paint, stains, mildew, oil, compacted dirt and grime from decks, siding, driveways and patios.
The Soap Nozzle is used to apply cleaning solution to any surface. Use to provide a thorough cleaning to all surfaces.

Working with Detergents

For best results see Cleaning Tips for specific information on how to clean different surfaces.
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 and will protect the internal parts of the pressure washer for a longer life.
For Kärcher detergents, check your retailer or visit our website: www.Karcher.com/us
CAUTION
Never Use:

• Bleach, chlorine products, and other corrosive chemicals
• Liquids containing solvents (i.e., paint  thinners, gasoline, oils)
• Trisodium phosphate products
• Ammonia products
• Acid-based products

These chemicals will harm the unit and will damage the surface being cleaned.
The use of these items will void the warranty.
Detergents can only be applied at low pressure.

1. Install the soap nozzle to the quick connect on the end of the wand by pulling the collar back, inserting the soap nozzle, then pushing the collar back. Check to make sure the nozzle is secure.
2. Fill the soap tank with Kärcher detergent. This machine is equipped with a dual soap tank system, allowing you to use two different detergent solutions.
   
3. Turn on the pressure washer by stepping on the foot pedal. Pull the trigger to operate the unit. Liquid detergent is drawn into the unit and mixed with water. Apply detergent to the work area. Do not allow detergent to dry on the surface.

Cleaning Tips
CAUTION

• Before cleaning any surface an inconspicuous 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 a pressure washer may remove the loose paint from the surface. When used on surfaces that might come in contact with food, flush surfaces with plenty of drinking water. For additional cleaning tips, visit our website: www.Karcher.com/us/

Deck Cleaning
(With or without detergent).
Pre-rinse deck and surrounding area with fresh water. If using detergent, apply to the surface at low pressure. For best results, limit your work area to smaller sections of approximately 25 sq. ft (2.3 m²). Allow the detergent to remain on surface for 1-3 minutes. Do not allow detergent to dry on the surface. Rinse at high pressure in a long sweeping motion keeping the spray nozzle approximately 3-6 in. (7.5-15 cm) 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
