Grounding Instructions

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 in-

4 English

stalled by a qualified electrician. Do not
use any type of adapter with this pro­duct.

Ground Fault Circuit Interrupter

(GFCI) Protection

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 re­close 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.

WATER SUPPLY (Cold Water Only)

 CAUTION

Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.

! Water hose must be at least 5/8 inch

in diameter.

! Flow rate of water supply must not

fall below 2 GPM (gallons per minu-

te).

! 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 sol-

vents, e.g. paint thinners, gasoline,

oil, etc.

! Always prevent debris from being

drawn into the unit by using a clean

water source.

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.

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

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.
