Starting
-Dirt in the feed water could lead to the
appliance being damaged. To avoid this
risk, we recommend fitting a filter with
3/4" connection .
-If you are using an extension cable, it
should always be completely unwound
from the cable drum and have a sufficient
cross-sectional area (10 m = 1,5 mm²,
30m = 2,5 mm²).
Operation with high pressure
-The appliance is equipped with a pressu-
re-operated switch. The motor starts only
if the lever of the gun is pulled.
-The safety ratchet does not lock the lever
of the gun during operation but only
prevents it from opening unintentionally.
Suction operation
-Allow the pump to operate without the
high-pressure hose until water appears at
the high-pressure outlet without any
more bubbles.Then re-attach the high-
pressure hose.
Operation with Detergent
-We recommend that you use detergent
sparingly for the sake of the environment.
Observe the recommended dosage on
the detergent label.
-By offering you an individualised range of
clea-ning and preserving agents, Kärcher
guarantees trouble-free operation of the
unit.
-We recommend the following cleaning
methods:
Step 1: Loosening dirt
Spray on detergent sparingly and allow
to react for a short time.
Step 2: Removing dirt
Spray off the loosened dirt with the
high-pressure spray.
Switching Off
-After using a detergent, the appliance
should be rinsed clear. To do this, sus-
pend the detergent suction hose in a con-
tainer of clean water, and run the pump for
approx. 1 minute.
-Pull the trigger until there is no more pres-
sure in the appliance, and secure the
trigger with the safety ratchet against
unintentional opening.
-Frost will destroy an appliance which has
not been completely emptied of water.
Troubleshooting
!Note: Disconnect the appliance from the
power mains before all repair work.
Appliance does not Work
-Check whether the voltage shown on the
rating plate corresponds to that of the
power source.
-Check the connector cable for damage.
Appliance does not reach Pressure
-Set the spray lance to the maximum
working pressure.
-Vent the appliance.
-Clean the strainer in the water
connection.
-Check the inlet water flow rate.
-Check all inlet pipes to the pump for leaks
or block-age.
Strong Pressure Fluctuations
-Clean the high-pressure nozzle. Remove
dirt from the nozzle hole with a needle and
then rinse out with water from the front.
Pump Leaks
-3 drops per minute are permissible. In the
case of more serious leakage, you should
contact the authorized customer service.
No Detergent Suction
-Set the spray lance to the minimum
working pressure.
-Clean the detergent suction hose with fil-
ter, and check for leaks.
Spare Parts
-A selection of the most common spare
parts numbers is listed at the end of these
operating instructions.
General Information
Purpose
-Use the appliance to clean machines,
vehicles, buildings, tools etc.
-Clean facades, terrasses, garden equip-
ment etc. without detergent only with the
high-pressure spray.
-Engines may only be cleaned at locations
with appropriate oil separators (environ-
mental protection).
Safety Equipment
When the hand-held spary gun is closed,
the overflow valve switches off the
appliance via a pressure-operated switch.
The overflow valve is also a safety device
against exceeding the maximum allowable
working pressure.
