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.

Safety devices prevent injury and may not 
be modified or bypassed.

The switch prevents unintented starting of 
the appliance.  Stop the appliance during 
breaks or after operation.

The safety catch on the handgun prevents 
the appliance from being switched on unin-
tentionally.

"

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.

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).

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-
