Commissioning and operation

Before Startup

Push out the safety clip in the trigger
gun using e.g. a small screwdriver.
Join HP hose and trigger gun together.
Push clip in until it engages and check
that it is securely fastened by pulling on
the HP hose.

Water supply

According to the applicable regula-
tions, the appliance must never be
used on the drinking water net
without a system separator. Use a
suitable system separator manufactured by
Kärcher; or, as an alternative, a system
separator as per EN 12729 Type BA.
Water supply from mains
For connection values, see type plate/tech-
nical data.
Observe regulations of water supplier.
Use a fibre-reinforced hose (not includ-
ed) with a standard coupling:
- Minimum diameter, 1/2 inches (13 mm)
- Minimum length, 7.5 m
Screw the coupling unit (supplied) to
the water connection on the appliance.
Push the water supply hose onto the
coupling unit, then connect it to the tap.
Caution
Never operate the high-pressure cleaner
when the tap is turned off as dry running will
damage the HP pump.
If the water supply is not clean, the Kärcher
water filter must be used (special accesso-
ry - order No. 4.730-059).
Water supply from open reservoirs
When fitted with the appropriate accesso-
ries, this high-pressure cleaner can draw in
surface water, e.g. from water butts or
ponds (max. suction height 0.5 m).
Use the Kärcher water filter to protect
the HP pump and accessories (special
accessories). This filter removes dirt
from incoming water.

English
As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated fil-
ter should be used instead (special ac-
cessory) and suspended inside the
water butt.

ation: Switch on the appliance when the
HP hose is not connected and run it un-
til the water which discharges from the
HP outlet is free of bubbles. Switch off
appliance and connect HP hose.
Start up
Screw HP hose on to HP outlet on ap-
pliance.
Push the appropriate spray lance on to
the trigger gun and fasten it by turning it
through 90°.
Open tap.
Plug in the main plug.
Set main switch to "I/ON".
Press safety catch on the trigger gun to
release it and pull lever.

High pressure operation

Risk of injury
The trigger gun is subjected to a recoil force
when the water jet is discharged. Make
sure that you have a firm footing and are
also holding the trigger gun and spray lance
firmly.
Spray gun with EPC
EPC: 3-Step electronic power control.
Loose lever on the spray gun briefly
(less than one second) to change EPC-
setting.
The EPC power steps will be changed
one after another, from Step 3, over
Step 2, to Step 1. From Step 1 it will be
changed back to Step 3.
Step 3 - Maximum:
–
Maximum pressure and water flow.
Step 2 - Medium:
–
Reduced pressure and water flow.
Step 1 - Soft:
–
Gentle pressure and water flow.
