You need to use the matching high pressure nozzles to
ensure that your high pressure cleaner works properly.
Note:
Nominal pressure (p): See Operating Instructions or
type plate of your high pressure cleaner.
e.g.: K 6 – K 7, Kärcher 600 – Kärcher 770

Use yellow high-pressure nozzles.
Note:
The yellow high-pressure nozzles have already
been installed.
e.g.: K 4 – K 5, Kärcher 201 – Kärcher 560

Use grey high-pressure nozzles.
 Illustration
1 Loosen the safety clamp with a screwdriver.
2 Remove the protective grid.
3 Remove the clip.
4 Pull out the yellow high-pressure nozzle.
5 Insert the grey high-pressure nozzle.
6 Reinsert the clip.
7 Mount the protective grid on the pin.
8 Push the safety clamp in until it locks.
Note: Always use Kärcher water filter (order no. 4.730-
059.0) during suction operations of the high-pressure
cleaner.
Fasten the T-Racer to the high-pressure gun using the
extension pipes.

Illustration
1 Press the extension pipe into the bayonet catch of
the T-Racer.
2 Turn it by 90° until it locks into place.
3 Tighten the union nut.
Repeat this process even for the other joints.

Adjust the twist grip "Power" in accordance with the
surface to be cleaned.
 Outdoor surfaces should be swept before the T-
Racer is used to avoid damaging the high-pressure
nozzles.
 Prior to use on sensitive surfaces (e.g. wooden sur-
faces), test the product on an imperceptible spot, in
order to promptly detect any changes in the sur-
face.
 The T-Racer is not suited for scouring or scrubbing!
 Guide the T-Racer over the surface without effort.
 Do not remain at one spot; always keep moving
during cleaning.
ṇ CAUTION
Do not run over protruding corners!

Illustration
Fasten the T-Racer directly to the high-pressure gun.
1
Press the bayonet connection of the T-Racer into
the connection of the high-pressure gun, then turn
by 90° until it locks into place.
2 Tighten the union nut.
 Adjust the twist grip "Power" in accordance with the
surface to be cleaned.
ṇ CAUTION
Always hold the T-Racer at the handle while cleaning
the walls.

Illustration
The turning handle "power" is used to change the dis-
tance of the high-pressure nozzles to the surface to be
cleaned.

Illustration
Sturdy surfaces (e.g. tiles, concrete, stone)

Set turning handle "power" to "HARD".
For the effective cleaning of hard-to-remove con-
tamination.
Sensitive surfaces (e.g. wood)

Set turning handle "power" to "SOFT".
For the gentle cleaning of sensitive surfaces.
 Illustration
For normal surface cleaning, operate the foot
switch for surface cleaning (a).
A water stream will be emitted from the two high-
pressure nozzles in the rotor arm.
 Illustration
For edge and corner cleaning, operate the foot
switch for edge cleaning (b).
A water stream will be emitted from green high-
pressure nozzle.
Note
In order to achieve the optimum cleaning result, guide
the T-Racer along the corners.
