– The controls for the maintenance and service are light gray.

Proper use

Use this high pressure cleaner exclusively for:
– Cleaning machines, vehicles, buildings, tools.
– with accessories and spare parts approved by Kärcher.

Symbols on the machine

| High pressure jets can be dangerous if improperly used. The jet must not be directed at persons, animals, live electrical equipment or at the appliance itself.
---|---
Risk of damage from freezing water! During winter, store the device in a heated room or empty it.
| Danger of hearing damage. Always wear suitable hearing protection when working with the device. Risk of injury! Wear safety goggles.
| Risk of burns on account of hot surfaces!
| Beware of dangerous electrical current!

WARNING
Observe regulations of water supplier. According to applicable regulations, the appliance must never be used on the drinking water net without a system separator. A suitable system separator by KÄRCHER or alternatively a system separator according to EN
12729 type BA must be used. Water that was flowing through a system separator is considered non-drinkable.
CAUTION
Always connect the system separator to the water supply, never directly to the appliance!

Safety instructions

DANGER
Pointer to immediate danger, which leads to severe injuries or death.
WARNING
Pointer to a possibly dangerous situation, which can lead to severe injuries or death.
CAUTION
Pointer to a possibly dangerous situation, which can lead to minor injuries.
Hazard levels
ATTENTION
Pointer to a possibly dangerous situation, which can lead to property damage.
High pressure hose
DANGER
Risk of injury!
– Only use original high-pressure hoses.
– The high-pressure hose and the injection system must be suitable for the maximum operating pressure given in the Technical Data.
– Avoid contact with chemicals.
– Check the high pressure hose daily.
Do not use hoses with kinks.
Stop using the high pressure hose if the external wire layer is visible.
– Do not use the high-pressure hose anymore if the winding is damaged.
– Lay the high-pressure hoses in such a way that no vehicle can drive over it.
– Do not use high-pressure hoses that have been driven over, kinked, pressed or bent even if there is no externally visible damage.
– Store the high-pressure hoses in such a way that they are not subject to any mechanical load.
– Maximum tightening torque of the screwed connections of the high-pressure hose; 20 Nm.

Safety Devices

Safety devices serve to protect the user and must not be rendered in operational or their functions bypassed.
Power switch
The switch prevents unintented starting of the appliance. Stop the appliance during breaks or after operation.
Safety catch
The safety catch on the handgun prevents the handgun from being released unintentionally.
Overflow valve
– only for Classic variant
– If the hand spray gun is closed, the overflow valve opens and the entire water volume will flow back to the pump suction side.
Overflow valve is set and sealed by the manufacturer. Setting only by customer service.
Overflow valve with pressure relief
– only for Advanced variant
– If the hand spray gun is closed, the overflow valve opens and the entire water volume will flow back to the pump suction side.
– If the trigger gun is closed, the water ressure in the high-pressure hose is reduced. This reduces the actuating force of the trigger gun and increases the service life of the device.
Overflow valve is set and sealed by the manufacturer. Setting only by customer service.
Safety valve
The safety valve opens when the overflow valve is defective.
The safety valve is set by the manufacturer and sealed. Setting only by customer service.
Water shortage safeguard
The lack of water fuse shuts off the engine when the water supply is scarce (water pressure too low).
The indicator lamp “lack of water” will illuminate.
Thermostat valve
The thermostat valve protects the highpressure pump from unacceptable heating during circuit operation when the trigger gun is closed. The thermostat valve opens when the permissible water temperature of 80°C is exceeded and lets out the hot water into the open.
Motor protection switch
The motor protection switch interrupts the electric circuit if the motor is overloaded.

Start up

DANGER
Risk of injury! Device, supply lines, highpressure hose and connections must be in faultless condition. If they are not in a perfect condition then the device must not be used.
Check oil level

Replace the transport screw with the supplied bleed screw.
Check oil level of the high pressure pump.
The oil level must be at the centre of the oil level display.
Add oil if required (see technical specifications).

Attaching the Accessories
WARNING
Risk of injury due to unsuitable accessories. Only use accessories hat are approved for the working pressure of the device (see “Technical Data”). Only install accessories while the device is switched off. Maximum tightening torque of the screwed connections of the high-pressure hose; 20 Nm.

Connect high pressure hose and spray pipe to the hand spray gun.
Mount the power nozzle on the spray pipe. Tighten covering nut firmly.
Connect the high pressure hose to the high pressure connection point of the machine.

Power supply
– For connection values refer to technical specifications.
– The electrical connections must be done by an electrician according to IEC 60364-1.
WARNING
The highest allowed net impedance at the electrical connection point (refer to technical data) is not to be exceeded.
In case of any uncertainty regarding the present net impedance at your connection point, please contact your local power supply company.
**DANGER
– Check whether the voltage data on the type plate corresponds with the voltage of the power source.
– Unsuitable electrical extension cables can be dangerous. Only use approved and appropriately marked electrical extension cables with a sufficient line cross section when outdoors:
1 – 10 m: 10 mm2
10 – 30 m: 16mm 2
60 Hz model
With this appliance model, the matching mains plug must be installed onto the mains connecting line by an electrician.
Water connection
WARNING
Observe regulations of water supplier.
According to applicable regulations, the appliance must never be used on the drinking water net without a system separator.
A suitable system separator by KÄRCHER or alternatively a system separator according to EN 12729 type BA must be used.
Water that was flowing through a system separator is considered non-drinkable.
CAUTION**
Always connect the system separator to the water supply, never directly to the appliance! For connection values refer to technical specifications.

Connect the supply hose (minimum length 7.5 m, minimum diameter 1“) to the water connection point of the appliance (such as the tap).
The supply hose is not included.
