GROUND FAULT CIRCUIT

INTERRUPTER PROTECTION

WATER SUPPLY

(Cold Water Only)

This product is provided with a ground­fault circuit interrupter (GFCI) built into
the plug of the power-supply 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.
Contact Kärcher Customer Support.

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 INSULATED”. 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 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

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
