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 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. Use additional water filter.
Do not operate pressure washer
without the water turned on.
Avoid tipping the machine on its
side.

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.

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

When using on surfaces which might
come in contact with food, flush sur-
faces with plenty of drinking water.
