Control Elements; Troubleshooting - Kärcher T 550 T-Racer Manual

Working with detergent
The most commonly used KÄRCHER detergents can
be purchased ready to use in their Plug 'n' Clean deter-
gent bottles with locking lids. This will make the pesky
refilling and filling processes redundant.
Illustration
 Remove the lid from the Plug 'n' Clean detergent
bottle and press the detergent bottle into the deter-
gent connection with the opening facing down.
 Adjust the suction volume of the detergent solution
by means of the dosage regulator for detergents.
Note
– Bring the bottleneck into an upright position to com-
pletely empty the detergent bottle.
– Turn the detergent bottle around after cleaning,
close it and place it in the retainer for the Plug 'n'
Clean detergent bottle.
– Clean gravel surfaces without detergent.
– Do not adjust the detergent supply via the dosing
regulator for detergents while under pressure.
Cleaning wall surfaces
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.
CAUTION
Always hold the T-Racer at the handle while cleaning
the walls.

Troubleshooting

Pressure washer does not build up pressure or is
pulsating.
 Dismantle the high-pressure nozzles, check the
high-pressure nozzles for damage, rinse the T-
Racer with clean water then reinstall the high-pres-
sure nozzles.
You need to use the matching high pressure noz-
zles to ensure that your high pressure cleaner
works properly.
 Select and install the high-pressure nozzles in ac-
cordance with the pressure washer used.
No detergent infeed
 Check the settings at the dosage regulator for de-
tergent.
 Check whether the Plug 'n' Clean detergent bottle
is placed into the detergent connection facing
