Start Up; Water Supply; Operation - Kärcher K 7 Premium Bedienungsanleitung

Start up

 Park the appliance on an even surface.
 Insert the mains plug into the socket.

Water supply

For connection values, see type plate/technical data.
ATTENTION
Impurities in the water can damage the high-pressure
pump and the accessories. For protection, the use of
the KÄRCHER water filter (optional accessory, order
no. 4.730-059) is recommended.
Water supply from mains
Observe regulations of water supplier.
ATTENTION
Hose couplings made of metal with aquastop can dam-
age the pump! Please use plastic couplings or KÄRCH-
ER brass couplings.
 Attach the water supply hose to the coupling on the
water connection.
 Connect the water supply hose to the water supply.
 Completely open the water tap.
Drawing in water from open reservoirs
This high-pressure cleaner is suited to work with the
KÄRCHER suction hose with backflow valve (Optional
accessory, order no. 4.440-238) to draw in surface wa-
ter, e.g. from water butts or ponds (see specifications for
max. suction height).
 Remove coupling from the water connection.
 Fill the suction hose with water.
 Screw the suction hose into the water connection of
the appliance and insert it into the water source
(e.g. rainwater drum).
Remove air from appliance before operation.
 Turn on the appliance "I/ON".
 Unlock the lever on the trigger gun.
 Pull on the lever of the trigger gun; the device will
switch on.
 Let the appliance work until the water exits at the
hand spray gun without bubbles (max. 2 minutes).
 Release the lever on the trigger gun.
Note: Release the lever of the trigger gun; the de-
vice will switch off again. High pressure remains in
the system.
 Lock the lever on the trigger gun.
ATTENTION
Dry running of more than 2 minutes leads to damage of
the high-pressure pump. If the appliance does not build
up pressure within 2 minutes, switch the appliance off
and proceed in accordance with the instructions in
Chapter "Troubleshooting".
High pressure operation
CAUTION
Keep a distance of at least 30 cm when using the jet for
cleaning painted surfaces to avoid damage.
ATTENTION
Car tyres, paint or sensitive surfaces such as wood
should not be cleaned with the dirt blaster, as there is a
risk of damage.
Illustration
 Unwind the high pressure hose completely from the
hose drum. Hold on to the transport handle during
this procedure.
Note: If the hand crank is in its secured position,
fold it up first.
Illustration
 Push the spray lance into the trigger gun and fasten
it by turning it through 90°.
 Turn on the appliance "I/ON".
 Unlock the lever on the trigger gun.
 Pull on the lever of the trigger gun; the device will
switch on.
Note: Release the lever of the trigger gun; the de-
vice will switch off again. High pressure remains in
the system.
Operation with detergent
Note: Detergent can only be added when the device is
operated in low pressure mode.
DANGER
When using detergents, the material data safety sheet
issued by the detergent manufacturer must be adhered
to, especially the instructions regarding personal pro-
tective equipment.
Notes regarding the detergent: The most commonly
used KÄRCHER detergents can be purchased ready to
use in their Plug 'n' Clean detergent bottles with locking
lids. This will make the pesky refilling and filling process-
es 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.
Illustration
 Adjust the suction volume of the detergent solution
by means of the dosage regulator for detergents.
 Use spray lance with pressure regulation (Vario
Power).
 Turn the spray lance to "Mix" position.
Note: This will mix the detergent with the water
stream.
Recommended cleaning method
 Spray the detergent sparingly on the dry surface
and allow it to react, but not to dry.
 Spray off loosened dirt with the high pressure jet.
