Safety instructions

• It is essential that you read the safety instructions 5.951-949.0 before initial startup.

• Observe the national regulations for liquid jet cleaners.

• Observe the national accident prevention regulations. Liquid jet cleaners must be tested regularly.
  The test result must be recorded in writing.

• Do not modify the device or accessories.

Symbols on the device

The device may not be connected to the public drinking water network.
The high-pressure jet must not be directed at persons, animals, live electrical equipment or at the device itself. Protect the device from frost.

Safety devices

Safety devices protect the user and may not be disabled or functionally circumvented. The overflow valve, pressure switch an safety valve are set and sealed by the manufacturer. Adjustments are performed only by customer service.

Overflow valve with pressure switch

When the water quantity is reduced via the pressure/ quantity control on the trigger gun, the overflow valve opens and part of the water flows back to the suction side of the pump. When the trigger on the high-pressure gun is release, the pressure switch switches off the high-pressure pump and the high- pressure jet stops. The pump switches on again when the trigger is pulled.

Safety valve

The safety valve opens when the permissible operating pressure is exceeded and the water flows back to the suction side of the pump.

Initial startup

Electrical connection

DANGER
Risk of injury from electric shock
Use a plug to connect the device to the mains grid. Permanent connection to the mains grid is prohibited. The plug is used for disconnection from the mains.
See the type plate or technical data for the connection values.

1. Unwind the mains cable and place on the ground.
2. Plug the mains plug into the socket.

Water connection

Connection to a water line

⚠ WARNING
Health risk from return flow of contaminated water into the drinking water network.
Observe the regulations of your water supply company.
According to applicable regulations, the device must never be used with the drinking water network without a system separator. Use a system separator from
KÄRCHER or a system separator as per EN 12729
Type BA. Water that has flowed through a system separator is classified as undrinkable. Always connect the system separator to the water supply and never directly to the water connection on the device.

1. Check the feed pressure, input temperature and input amount of the water supply. See the “Technical data” section for the requirements.

2. Connect the system separator and water connection of the device with a hose (minimum length 7.5 m, minimum diameter 1”).
   The supply hose is not included in the scope of delivery.

3. Open the water inlet.

Suck water from the container

1. Screw the suction hose (order number 4.440-207.0) and filter (order number 4.730-012.0) onto the water connection.
2. Vent the device.

Vent the device

1. Unscrew the nozzle from the spray lance.
2. Allow the device to run until the escaping water is free of air bubbles.
3. In the case of venting problems, allow the device to run for 10 seconds and then switch it off. Repeat the procedure several times.
4. Switch off the device.
5. Screw the nozzle back in place.

Operation

⚠ DANGER
Risk of injury from the high-pressure water jet
Never fasten the trigger and safety lever in the actuated position.
Do not use the high-pressure gun when the safety lever is damaged.
Push the safety latch of the high-pressure gun forwards every time before starting work with the device.

Opening/closing the high-pressure gun

1. Opening the high-pressure gun: Actuate the safety lever and trigger.
2. Closing the high-pressure gun: Release the safety lever and trigger.

High-pressure operation

Note
The device is equipped with a pressure switch. The motor only starts up when the high-pressure gun is open.

1. Set the power switch to “I”.
2. Unlock the high-pressure gun by pushing the safety latch of the high-pressure gun to the rear.
3. Open the high-pressure gun.

Operation with detergent

Note
A cup foam lance (optional)is needed for operating with detergent.
⚠ WARNING
Health risk through incorrect handling of detergents
Observe the safety instructions on the detergent.
ATTENTION
Unsuitable detergents can damage the device and the object to be cleaned.
Use only detergents approved by KÄRCHER.

Observe the dosing recommendations and notes provided with the detergent.
Use detergents sparingly to help conserve the environment.
KÄRCHER detergents ensure fault-free operation. Ask us for a consultation, request our catalogue or our detergent information sheets.

6. Connect the foam nozzle to the high-pressure gun and hand-tighten.
7. Start up the high-pressure cleaner.

Recommended cleaning method

1. Spray the detergent sparingly on the dry surface and let it work for a while (do not let it dry).
2. Rinse off the loosened dirt with the high-pressure jet.

Rinsing out the foam lance

The foam lance must be flushed after use to prevent the formation of detergent deposits.

1. Unscrew the container.
2. Pour the remaining detergent back into the original packaging.
3. Fill the container with clear water.
4. Screw the container onto the foam nozzle.
5. Operate the foam nozzle for approx. 1 minute to flush the detergent residue.
6. Empty the container.

Interrupting operation

1. Close the high-pressure gun, the device will switch off.
2. Lock the high-pressure gun by pushing the safety latch of the high-pressure gun to the front.

Note
The water pressure in the high-pressure hose is reduced by approx. 70% when the device is switched off.
This reduces the actuating force of the high-pressure gun and extends the service life of the device.

Continuing operation

1. Close off the water inlet.
2. Open the high-pressure gun.
3. Set the power switch to “I” and allow the device to run for 5 to 10 seconds.
4. Close the high-pressure gun.
