IMPORTANT SAFETY INSTRUCTIONS

WARNING!

When using this product basic
precautions should always be

followed, including the following:

 Read all the instructions before us-

ing the product.

 To reduce the risk of injury, close su-

pervision is necessary when a prod­uct is used near children.

 Know how to stop the product and

bleed pressures quickly. Be thor­oughly familiar with the controls.

 Stay alert – watch what you are do-

ing.

 Do not operate the product when fa-

tigued or under the influence of alco­hol or drugs.

 Keep operating area clear of all per-

sons.

 Do not overreach or stand on unsta-

ble support. Keep good footing and
balance at all times.

 Follow the maintenance instructions

specified in the manual.

 This Product Is Provided With A

Ground Fault Circuit Interrupter Built
Into The Power Cord Plug. If Re­placement Of The Plug Or Cord Is
Needed, Use Only Identical Re­placement Parts.

 Risk of Injection or Injury – Do Not

Direct Discharge Stream At Per­sons.

 High pressure jets can be dangerous

if misused. The jet must not be di­rected at persons, animals, electrical
devices, or the machine itself.

 Wear safety goggles.
 Do not use acids and solvents in this

product. These products can cause

physical injuries to the operator and
irreversible damage to the machine.

 To reduce the risk of electrocution,

keep all connections dry and off the
ground. Do not touch plug with wet
hands.

 The Trigger Gun Safety Lock PRE-

VENTS the trigger from accidentally
being engaged. This safety feature
DOES NOT lock trigger in the ON
position.

 Do not use extension cord with this

unit.

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

English 5

GROUND FAULT CIRCUIT IN-

TERRUPTER 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
re-close 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

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 1/2

inch or 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 sol­vents, 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.

English 13

Barbecue Grills, Outdoor Power

Equipment & Gardening Tools

(with or without detergent). Pre-rinse

cleaning surface with fresh water. If us­ing Kärcher Pressure Wash or Degreas­er, apply detergent at low pressure.
Allow Pressure Wash 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.

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

spray nozzle approximately 3-6 inches
from the cleaning surface. For best re­sults, clean from top to bottom and from
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.
