A Pressure Washer is essentially a powerful electric motor driving a set

of pistons that force water through a small nozzle, thus creating a

pressurised jet of water. This provides the cleaning power behind the

Karcher Pressure Washer.

2. SAFETY INSTRUCTIONS

Never use defect connection or extension lines! If the connection line

is damaged, it must be replaced with a special connection line that is

available from the manufacturer or his customer service.

Please make sure that the connection or extension lines are not

damaged by being ran over, pulled or dragged. Protect the

connection lines from heat, oil, and sharp edges.

Never touch the mains plug and the socket with wet hands.

The connection between connection line and extension line must not

lie in the water.

All current-carrying components within the working area must be jet-

proof.

The appliance may only be connected to an electrical connection that

was performed by an electrician according to IEC 60364.

Only connect the appliance to alternating current. The voltage must

comply with the voltage specified on the typeplate.

To avoid electric accidents, we recommend to use sockets with a

series connected residual current operated device (rated breaking

current max. 30 mA).

Warning: Inappropriate extension lines may be dangerous. If you

work outside, only use extension lines that are approved and

specifically labelled and provide of a sufficient conductor cross

section (see page 5).

The plug and the coupling of an extension line must be waterproof.

Always unwind the extension line completely from the cable drum.

The operation of the device in hazardous locations is not admissible.

Please comply with the corresponding safety instructions if you use

the appliance in danger areas (e.g. filling stations).

Do not turn on the appliance if the power supply line or important

components of the appliance, such as safety components, high-

pressure hoses, spray jet, are damaged.

Warning: High-pressure hoses, fittings, and couplings are of

importance for the appliance safety. Only use high-pressure hoses,

fittings, and couplings recommended by the manufacturer.

The appliance is not intended for use by young children or infirm

persons without supervision. Young children should be supervised to

ensure that they do not play with the appliance.

The operator must use the appliance properly. He must take the local

conditions into consideration and must pay attention to third persons,

in particular children, while working with the appliance.

Warning: Do not use the appliance if third persons are within the

reach of the appliance unless such persons wear protective clothes.

Warning: High-pressure jets may be dangerous if they are used

improperly. The jet must not be directed at people, animals, active

electrical equipment, or the appliance itself.

Never direct the jet at yourself or third persons to clean clothes or

shoes.

Never use the appliance to spray objects containing hazardous

substances (e.g. asbestos).

Warning: Vehicle tyres/tyre valves may be damaged and burst by the

high-pressure jet. A first sign is the discoloration of the tyre. Damaged

vehicle tyres/tyre valves are hazardous. Always perform the cleaning

with a minimum distance of 30 cm.

Cleaning operations during which oil saturated waste water is

generated, such as engine cleaning and underbody cleaning, may

only be performed in cleaning locations that are equipped with an oil

separator.

If you clean varnished surfaces, please respect a minimum distance

of 30 cm to avoid damages.

Never take in solvent-containing liquids or undiluted acids and

solvents! These include, for example, benzene, paint thinner, or

heating oil. The spray is highly inflammable, explosive, and toxic. Do

not use acetone, undiluted acids, and solvents as they affect the

materials used on the appliance.

If required, wear appropriate protective clothes and glasses to protect

yourself from return spray.

Never leave the appliance unattended as long as it turned on.

3.2 Water Connection

• The minimum length of supply hosepipe advised for maximum user

convenience is 7.5 metres with a diameter of 12.5 mm (1/2") to allow

free flow of inlet water to the machine so avoiding backpressure and

any associated potential damage to your machine.

• Attach your supply hosepipe with its connector to the coupling on the

machine (No.7) and the other end should be connected to a suitable

water supply.

3.3 Electrical Connection

• Ensure the Power Switch (No.4) is in the “OFF” position before

connecting the factory fitted Plug attached to the Mains Electric Lead

(No.14) into an earthed socket. (it is recommended that an RCD plug

socket is used.)

If using an Extension Cable make sure it is completely unwound

from the cable drum and is the correct diameter.

3.4 SuctionMode-

anaddedbenefitoftheKarcherPressureWasher

• If you are drawing water from a static water supply such as a water

butt disconnect the water connection/hosepipe with coupling (No.7)

from the machine and replace with a suction hose and filter (Part

No. 4.440.238) that can be purchased as an accessory.

• Disconnect the Spray Lance from the Spray Gun.

• Allow the pressure washer to operate without the Spray Lance fitted

until water flows from the Spray Gun without bubbles.

• Re-connect the Spray Lance to the Spray Gun.

Dirt in the drawn water could damage your Pressure Washer !

To avoid this risk please use a suitable filter - Part No. 4.730-059.
