Frequently Asked Questions - WR 100 Kärcher

How do I mount the WR 100 spray lance on the pressure washer?

Push the Power nozzle into the screw connection, insert a seal, then apply the supplied metal adhesive to the spray lance thread before screwing on the lance. Respect the drying time of the adhesive.

What water temperature should I use with the WR 100?

The device operates with hot water between 90 °C (minimum) and 100 °C (maximum). Set the pressure washer to a maximum of 98 °C.

How do I know when the water is at the right temperature?

The temperature display changes color: the fields turn from black to brown, then the right bar becomes green when the device is ready.

What water flow rate is needed for optimal operation?

The inlet flow rate must be between 8.3 and 16.7 l/min. Use a suitable Power nozzle to limit flow if necessary.

How do I use the WR 100 for weeding?

Pass the lance slowly over the weeds. The hot water should come out almost without pressure, with slight steam formation. Repeat if necessary.

What safety precautions should I observe?

Never direct the jet at people, animals, or electrical installations. Wear protective gloves and safety goggles. Do not touch the lance during operation.

How do I clean and maintain the WR 100?

After each use, run the lance with cold water for 2 minutes to cool it. Clean the nozzles regularly to prevent clogging. Store the device in a frost-free place.

What should I do if the pressure washer shuts off or the burner doesn't start?

Check that the nozzles on the lance are not clogged. Clean them if necessary.

How do I adjust the height of the lance above the ground?

Loosen the star handle screw, adjust the lance in the bracket to a height of 50 to 100 mm above the surface, then retighten the screw.

Where can I find accessories and spare parts?

Use only original Kärcher accessories and parts. Visit www.karcher.com for more information.

Flow restrictor

In order to maintain a consistently high temperature (above 90^ C) of the water, a power nozzle must be inserted into the screw connection of the spray bar to restrict the flow.

Note

The necessary power nozzle is matched to the corresponding high-pressure cleaner and must be ordered separately.

Spray bar

Installing the spray bar

Close-up of a mechanical tool with a magnified inset showing internal components (no text or symbols visible)

→ Push power nozzle into the screw connection.
→ Insert the sealing ring between the power nozzle and the spray lance.

→ Apply metal glue 6.867-075.0 (provided) to the thread of the spray lance.
→ Screw the spray bars onto the spray lance.

Note

Observe drying time of the metal glue!

Note

The connection can no longer be loosened after the metal glue has hardened.

Note

The openings of the spray bar must face downwards not forwards.

Installing chassis and Suspension (WR 50)

Note

If necessary, the WR 50 can be used with the chassis and suspension.

Mechanical component diagram showing a yellow sensor or sensor mounted on a vehicle chassis with arrows indicating motion direction (no text or symbols)

→ Insert spray bar into the chassis and suspension support.

Note

On the support, adjust the clearance between the spray bar and the surface (ap-prox. 50 mm - 100 mm above the surface).

→ Loosen the star handle screw.
→ Move the spray bar in the holder.
→ Tighten star handle screw.

Operation

⚠ WARNING

Risk of burns! The spray bar must be installed in such a way that the outlet openings face downwards.

Do not direct the water jet on persons or animals.

Do not touch WR 20/ WR 50 / WR 100 or reach into the water stream during operation.

→ Set the device switch on the high-pressure cleaner to max. 98 °C.
→ If installed, set the Servo Control to the max. setting.

Note

Depending on the high-pressure cleaner in use, the heating-up time can last between 2 and 5 minutes.

Temperature display

The temperature indicator provides information on when the required water temperature has been reached.

→ Switch on the high pressure cleaner and pull the lever of the high pressure gun.
→ Wait until hot water emerges from the spray bar.
→ The temperature indicator changes with the increasing water temperature.
The colour of the indicator fields changes from left to right from black to brown.
→ When the bar is coloured completely green at the right, the device is ready for operation.

Weed removal

→ Guide the spray bar slowly over the weed.
→ Repeat the procedure several times if required.

Note

The optimal effect has been achieved when the hot water flows with almost no pressure and a light steam formation.

Shutting down

⚠ WARNING

Risk of burns! Allow WR20 / WR 50 / WR 100 to cool before removal.

→ After the operation, operate the spray bar with cold water for two minutes in order to cool it down.
→ If necessary, rinse the spray bars and chassis and suspension (WR 50 / WR 100) with clear water.

Care

→ Protect the appliance against frost.
→ remove any dirt, soil and plant residue from the chassis and suspension (WR 50 / WR 100)
→ Regularly check the nozzles on the spray bar for blockages.

Transport

Mind the weight of the appliance during transport.

Storage

■ Consider the weight of the appliance when storing it.
■ Store the appliance in a frost free area.

Troubleshooting

Steam is coming out of the spray bar:

→ Reduce the temperature setting on the high-pressure cleaner.

The emerging water pressure is too high:

→ Mount power nozzle in screw connection.
→ Select a suitable power nozzle (see table).

High-pressure cleaner switches off/the high-pressure cleaner burner does not start:

→ Check the nozzles on the spray bar for soiling.
→ Check the nozzles on the spray bar for calcification.

The wheels of the chassis and suspension (WR 50 / WR 100) cannot be turned:

→ Check wheel axle and bearings for soiling.
