use of other detergents or chemicals
may compromise the safety of the appli-
ance or cause appliance damage.
! Make sure that the power cord or exten-
sion cables are not damaged by running
over, pinching, dragging or similar. Pro-
tect the power cords from heat, oil, and
sharp edges.
! The connection between the power cord
and extension cable must not lie in wa-
ter.
! All current-conducting parts in the work-
ing area must be protected against jet
water.
! The appliance may only be connected to
an electrical supply which has been in-
stalled in accordance with IEC 60364.
! The appliance may only be connected to
alternating current. The voltage must
correspond with the type plate on the ap-
pliance.
! The minimum fuse rating required at the
sokket outlet is 10 A (slow-blow).
! To avoid accidents due to electrical
faults we recommend the use of sockets
with a line-side current-limiting circuit
breaker (max. 30 mA nominal tripping
current).
! The plug and coupling of the extension
cable used must be watertight.
! Always fully unroll the extension cable
from the cable drum.

Commissioning and operation

Before Commissioning

" Remove the coupling element from the
lower packaging unit and mount it.
" Remove both bearing wheels from the
lower packaging units.
" Insert the bearing wheels into the axle
box and lock them.
" Mount HP hose clip to HP hose.
" Push out the safety clip in the handgun
using e.g. a small screwdriver.
" Join HP hose and handgun together.
" Push clip in until it engages and check
that it is securely fastened by pulling on
the HP hose.

Water supply

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). - Mini-
mum 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 accessory
- order No. 4.730-059).
Drawing in water 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).
" As the standard coupling system is not
suitable for use in suction mode, the
Kärcher suction hose with integrated fil-
