IMPORTANT SAFETY IN-

STRUCTIONS

몇 WARNING

When using this product basic precau­tions should always be followed, in­cluding the following:

1 Read all the instructions before us-

ing the product.

2 High pressure jets can be danger-

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

3 To reduce the risk of injury, close

supervision is necessary when a
product is used near children.

4 Know how to stop the product and

bleed pressures quickly. Be thor­oughly familiar with the controls.

5 Stay alert – watch what you are do-

ing.
6 Wear safety goggles.
7 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 ma-

chine.
8 Do not operate the product when fa-

tigued or under the influence of al-

cohol or drugs.
9 Do not overreach or stand on unsta-

ble support. Keep good footing and

balance at all times.
10 To reduce the risk of electrocution,

keep all connections dry and off the

ground. Do not touch plug with wet

hands.
11 The Trigger Gun Safety Lock pre-

vents the trigger from accidentally

being engaged. This safety feature

DOES NOT lock trigger in the ON

position.

12 Keep operating area clear of all per-

sons.

13 Follow the maintenance instruc-

tions specified in the manual.

14 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.

15 Risk of Injection or Injury – Do Not

Direct Discharge Stream At Per­sons.

16 Do not use extension cord with this

product.

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.

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 the replacement of the plug or cord is
needed use identical replacement
parts.

WATER SUPPLY

(Cold Water Only)

몇 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 inch

in diameter.

– Flow rate of water supply must not

fall below 2.6 GPM (gallons per

minute).

– Flow rate can be determined by

running the water for one minute

into an empty 5-gallon container.

– The water supply temperature must

not exceed 140°F/60°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.

CANADA

몇 WARNING

Do not spray electrical apparatus and
wiring.

Do not use with flammable liquids and
toxic chemicals.
Injection hazard: equipment can cause
serious injury if the spray penetrates
the skin. do not point the gun at anyone
or any part of the body. In case of pen­etration seek medical aid immediately.

This system is capable of producing
13700 kPa/2000 PSI. To avoid rupture
and injury, do not operate this pump
with components rated less than
13700 kPa/2000 PSI working pressure
(including but not limited to spray guns,
hose and hose connections).

Before servicing, cleaning or removing
any parts, shut off power and relieve
pressure.

EXTENSION CORDS

Use only 3-wire extension cords that
have 3-prong grounding-type plugs
and 3-pole cord connectors that accept
the plug from the product. Use only ex­tension cords that are intended for out­door use. These extension cords are
identified by a marking "Acceptable for
use with out-door appliances: store in­doors while not in use." Use only ex­tension cords having an electrical
rating not less than the rating of the
product. Do not use damaged exten-

4 EN

– 2

sion cords. Examine extension cord
before using and replace if damaged.
Do not abuse extension cord and do
not yank on any cord to disconnect.
Keep cord away from heat and sharp
edges. Always disconnect the exten­sion cord from the receptacle before
disconnecting the product from the ex­tension cord.
If you are using an extension cord, it
should always be completely unwound
from the cable drum.
Up to 100 ft = 10/3 AWG.

몇 WARNING

To reduce the risk of electrocution,
keep all connections dry and off the
ground. Do not touch plug with wet
hands.

Safety instructions

– Before first start-up it is definitely

necessary to read the operating in­structions and safety indications Nr.

5.951-949!

– Please follow the national rules and

Symbols in the operating in-

structions

 Danger

Immediate danger that can cause se­vere injury or even death.

몇 Warning

Possible hazardous situation that
could lead to severe injury or even
death.

Caution

Possible hazardous situation that
could lead to mild injury to persons or
damage to property.

Symbols on the machine

High-pressure jets can be
dangerous if improperly

used. The jet may not be di­rected at persons, animals, live electri­cal equipment or at the appliance itself.

According to the applicable
regulations, the appliance

must never be used on the
drinking water net without a system
separator. Use a suitable system sep­arator manufactured by Kärcher; or, as
an alternative, a system separator as
per EN 12729 Type BA.
Water flowing through a system sepa­rator is considered non-drinkable.

Proper use

Use this high pressure cleaner exclu­sively for

– Cleaning using low pressure jet and

detergent (for e.g. for cleaning ma­chines, cars, buildings, tools),

– For cleaning using high pressure jet

without detergent (for e.g. for clean­ing facades, terraces, garden appli­ances).

For stubborn dirt, we recommend the
use of the dirt blaster as a special ac­cessory.

Safety Devices

Safety devices serve for the protection
of the user and must not be put out of
operation or bypassed with respect to
their function.

Overflow valve with pressure

switch

While reducing the water supply/quan­tity regulation at the pump head, the
overflow valve opens and part of the
water flows back to the pump suck
side.

6 EN

– 4

If the lever on the trigger gun is re­leased the pressure switch turns off the
pump, the high-pressure jet is stopped.
If the lever is pulled the pump is turned
on again.

Safety valve

The safety valve opens when the per­missible operating pressure is exceed­ed; water flows back to the suction side
of the pump.
The overflow valve, pressure switch
and safety valve are set and sealed at
the factory.
Setting only by customer service.

Environmental protection

The packaging material can
be recycled. Please do not
throw the packaging materi­al into household waste;
please send it for recycling.

Old appliances contain
valuable materials that can
be recycled; these should
be sent for recycling. Batter­ies, oil, and similar sub­stances must not enter the
environment. Please dis­pose of your old appliances
using appropriate collection
systems.

Please do not release engine oil, fuel
oil, diesel and petrol into the environ­ment Protect the ground and dispose
of used oil in an environmentally­clean manner.
