ing.

Do not operate the product when fa-

tigued or under the influence of alco-

hol 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 replace-

ment of the plug or cord is needed,

use only identical replacement parts.

WARNING

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 di-

rected at persons, animals, electrical

devices, or the unit itself.

Wear safety goggles.

WARNING

Risk Of Explosion – Do not spray

flammable liquids.

Do not use acids, alkaline, solvents,

or any flammable material in this

product. These products can cause

physical injuries to the operator and

irreversible damage to the machine.

CAUTION

Gun Kicks Back – Hold with both

hands.

The Trigger Gun Safety Lock pre-

vents the trigger from accidentally

being engaged. This safety feature

DOES NOT lock trigger in the ON po-

sition.

WARNING – Risk of Electrocution

CAUTION

This unit has been designed for use with

cleaning detergents recommended by

the manufacturer. The use of other

cleaning detergents may affect the oper-

ation of the machine and void the war-

ranty.

WARNING

IMPORTANT SAFETY INSTRUCTIONS

English 5

TURE AND INJURY, DO NOT

OPERATE THIS PUMP WITH COM-

PONENTS RATED LESS THAN 1600

PSI WORKING PRESSURE (INCLUD-

ING BUT NOT LIMITED TO SPRAY

GUNS, HOSE AND HOSE CONNEC-

TIONS).

BEFORE SERVICING, CLEANING

OR REMOVING ANY PARTS, SHUT

OFF POWER AND RELIEVE PRES-

SURE.

IF CONNECTION IS MADE TO A PO-

TABLE WATER SYSTEM, THE SYS-

TEM SHALL BE PROTECTED

AGAINST BACKFLOW.

In a double-insulated product, two sys-

tems 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 dou-

ble-insulated product requires extreme

care and knowledge of the system, and

should be done only by qualified service

personnel. Replacement parts for a dou-

ble-insulated product must be identical

to the parts they replace. A doubleinsu-

lated product is marked with the words

“DOUBLE INSULATION” or “DOUBLE

INSULATED”. The symbol “ ” may also

be marked on the product.

This pressure washer is provided with a

ground-fault 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.

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 con-

nected directly to the public drinking wa-

ter 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 sol-

vents, e.g. paint thinners, gasoline,

oil, etc.

Always prevent debris from being

drawn into the unit by using a clean

water source.

WARNING

To avoid serious injury never point

spray nozzle at yourself, other per-

sons or animals.

Always test an inconspicuous area

before cleaning with high pressure.

This nozzle features a steady powerful

high pressure spray pattern, for general

cleaning.

This nozzle features a 0º pencil jet

which rotates 360º for maximum dirt

cutting action, effectively increasing

cleaning performance up to 50%.

This nozzle combines the cleaning

performance of a 0º pencil jet with

the surface coverage of a wide angle

nozzle.

Not recommended for soft materi-

als, siding, painted surfaces,

decks or autos.

Before cleaning any surface an in-

conspicuous area should be cleaned

to test spray pattern and distance for

maximum cleaning results.

USING THE ACCESSORIES

Spray wand

Dirtblaster®

English 9

pull trigger to operate unit.

ÎSTEP 5:

Cleaning up: Always draw fresh wa-

ter through the detergent tank or si-

phon tube when done to flush any

remaining detergents from the injec-

tion system.

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 envi-

ronment and your pressure washer. The

special formula won’t clog the suction

tube filter and will protect the internal

parts of the pressure washer for a longer

life. For Kärcher® Detergents, check

your retailer or visit our website:

corrosive chemicals

– Liquids containing solvents (i.e.,

paint thinners, gasoline, oils)

– Tri-sodium phosphate products

– Ammonia products

– Acid-based products

These chemicals will harm the unit and

will damage the surface being cleaned.

Use of these items will void the war-

ranty.
