Frequently Asked Questions - FRV 50 ME Kärcher

How to install nozzles on the rotating arm?

Insert the O-ring into the notch of the rotating arm, place the nozzle, then tighten the cap nut. Adjust the wrench flat of the nozzle parallel to the rotating arm. Use the supplied wrench to tighten the cap nut (22 mm opening).

What is the maximum water pressure?

The maximum water pressure is 25 MPa (250 bar). Do not exceed this pressure.

Can I use hot water with this surface cleaner?

Yes, the maximum water temperature is 85 °C. After using hot water, cool the unit by rinsing with cold water for 2 minutes.

What to do if the rotating arm does not turn?

Check if the cleaning nozzles are dirty. If clogged, clean them. Make sure the water pressure is sufficient.

Why does the suction power drop?

This may be due to a worn brush crown (to replace), a clogged suction channel or hose (to clean), or a clogged injector nozzle (to clean).

How to maintain the surface cleaner?

After each use, rinse the steering wheels with clean water, then spray with lubricating oil. Protect the unit from frost and do not let it rest on the brush.

What accessories are available?

Accessories: flexible attachment (ref. 2.642-528.0), dirt collector (2.642-532.0), flexible holder (2.042-001.0), FRV 50 ME brush (6.371-011.0), extension hose (4.441-040.0).

How to choose the right nozzle kit?

Read the nozzle orifice size on the nameplate of your pressure washer. Select the corresponding kit from the table in the manual (e.g., orifice 036-040 → kit 2.431.0).

What are the important safety instructions?

Never direct the spray at people, animals, electrical installations or the unit itself. Wear protective gloves and goggles. Wait for the rotating arm to stop completely before intervening.

How to connect the surface cleaner to the pressure washer?

Grease the O-rings of the fitting, screw the pressure washer gun handle onto the surface cleaner and tighten firmly by hand (or using a 27 mm open-end wrench).

Nozzles packet

You need to use the matching high pressure nozzles to ensure that your high pressure cleaner works properly.

Note:

The required packets of nozzles have been adjusted to suit the corresponding high pressure cleaners and must therefore be ordered separately.

Figure 1, see cover page

1 Nozzle size (example)

→ Read the nozzle size from the type plate of the high-pressure cleaner.
→ Select the nozzle package that is suitable for the high-pressure cleaner from the following table.

Nozzle size high-pressure cleaner	Nozzle package	Nozzle size nozzle package
036...040 2.64	2-431.0 2x10	+ 20
041...045 2.64	2-432.0 2x11	+ 23
046...050 2.64	2-433.0 2x12	+ 26
051...080 2.64	2-982.0 2x20	+ 40
081...100 2.64	3-769.0 2x30	+ 40

Assemble nozzle packet

Figure 2, see cover page

1 O ring
2 Rotation arm
3 Nozzle
4 Union joint

→ Inser the O ring in the nut of the rotation arm.

→ Place the nozzle on it.

→ Slightly fasten the nozzle with the Union joint.

Note:

The exit jet must be directed parallel to the rotation arm.

Figure 3, see cover page

→ Adjust the wrench area of the nozzle (width 10) so that it is parallel to the rotation arm.
→ Tighten the Union joint (width 22) using a wrench.
→ Repeat the process on the second rotation arm.

Note:

Do not attach the nozzles for the surface cleaner to the spray lance of the high-pressure cleaner.

Figure 4, see cover page

1 Injector nozzle
2 W r e n c h

→ Screw the injector nozzle into the injector using the wrench and tighten it fingertight (8 Nm).

The wrench is included with the nozzle set.

Operation

Figure 5, see cover page

1 Trigger gun with control knob
2 Trigger gun without control knob
3 Nipple, short
4 Nipple, long

In delivery condition, the short nipple is installed on the device for use on a trigger gun with a control knob.

For use with a trigger gun without a control knob, the short nipple must be unscrewed and replaced by the enclosed long nipple. Grease the O-rings of the nipple before installation.

Figure 6, see cover page

→ Connect the trigger gun of the high-pressure cleaner to the surface cleaner and hand-tighten it.
Tighten using a wrench (27 mm) if needed.

△CAUTION

A strong wastewater jet will emerge from the hose connection. Do not use the surface cleaner without a hose.

Figure 7, see cover page

→ Grease the O-ring at the end of the hose using the accompanying grease prior to installation.
→ Insert the accompanying hose at the hose connection of the surface cleaner and secure it by turning.
→ Route the other end of the hose to a drain and secure it by means of the accompanying hook-and-loop tape.

Note:

If possible, lay hose without any slopes. Maximum delivery height of the waste water is 1 m.

The free end of the hose can be attached by means of the included Velcro tape (e.g. on a drain grid).

If necessary, use extension hose (see "Accessories").

→ Hold the trigger gun and the handle of the surface cleaner firmly with both hands.
→ Guide the surface cleaner so that it remains close to the surface to be cleaned.

Shutting down

→ After operation with hot water, operate the surface cleaner with cold water for two minutes to cool it down.
→ If necessary, rinse the surface cleaner and the suction hose with clear water.

Care

→ Protect the appliance against frost.
→ Do not allow bristles to deform during storage.

Note:

In order to ensure a good suction result, please do not place the surface cleaner onto the brush crown after use.

→ Rinse the steering rollers with clear water after use and spray with creeping oil after they have dried.
