Safety devices

Safety devices serve to protect against injuries and

must not be changed or circumvented.

Relief valve with pressure switch

When the lever on the handgun is released the pres-

sure switch switches off the pump and the high-pres-

sure jet ceases. When the lever is pulled the pressu-

re switch switches on the pump again.

Moreover, the relief valve prevents the permissible

operating pressure from being exceeded.

The safety button on the handgun prevents inadver-

tent switching on of the unit.

Environmental protection

Dispose of packaging

The packaging materials are recyclable. Please hand

in the packaging for recycling.

Dispose of old equipment

In the development of this appliance careful atten-

tion has been given to its ability to be easily recycled.

Nevertheless, it contains parts or substances which

should not go into the household rubbish. You can

obtain information from any Kärcher sales house

about disposal facilities which protect the environ-

ment.

use of this unit you save up to 85 % of the water

otherwise needed. The unit can also be operated

with rain-water (use a water filter, order-no. 4.730-097).

the dosage recommendations which are supplied with

Connection requirements

Electrical connection

The voltage shown on the rating plate must match

the supply voltage. The current source must be

properly earthed.

Only use splash-protected extension cable with a

sufficient conductor cross-section (10 m: 3 x 1.5 mm²,

30 m: 3 x 2.5 mm²) and unwind completely from the

cable drum.

Connection to water line

Comply with the stipulations of the water supply com-

pany.

Only use supply hoses (not supplied) with the follo-

wing dimensions: length at least 7.5 m, diameter at

least ½”.

See rating plate or Technical Data for connected values.

Operation

Serious danger!

Vehicle tyres and tyre valves can be damaged by

the high-pressure jet and become perforated. The

first sign of this is a discoloration of the tyre. When

cleaning them maintain a distance of at least 30 cm.

Never grasp the power plug with wet hands.

Before each use check the power cord and power

plug for damage. Have a damaged power cord re-

placed immediately by an authorized Kärcher ser-

vice point or an electrical specialist.

Before each use check the high-pressure hose for

damage. Replace a damaged high-pressure hose

immediately.

Danger of injury!

Owing to the water jet emerging from the high-pres-

sure nozzle a recoil force operates on the handgun.

Ensure you have a secure footing and hold the hand-

gun and spray lance firmly.

If necessary wear protective clothing for protection

against return spray.
