Water Supply; Before Startup - Kärcher K 3.150 Betriebsanleitung

Water supply

According to the applicable regula-
tions, the appliance must never be
used on the drinking water supply
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
flowing through a system separator is con-
sidered non-drinkable.
Water supply from mains
Observe regulations of water supplier.
For connection values, see type plate/tech-
nical data.
Use a fibre-reinforced water hose (not
included) with a standard coupling.
(Minimum diameter 1/2 inch (13 mm),
minimum length 7.5 m).
Screw the coupling element (supplied)
to the water connection on the appli-
ance.
Push the water supply hose onto the
coupling unit, then connect it to the wa-
ter supply.
Drawing in water from open reservoirs
This high-pressure cleaner is suited to work
with the KÄRCHER suction hose with back-
flow valve (Optional accessory, order no.
4.440-238) to draw in surface water, e.g.
from water butts or ponds (see specifica-
tions for max. suction height).
Fill the KÄRCHER suction hose with
backflow valve with water, screw to wa-
ter supply and hang into the water butt.
Appliance ventilation: Switch the appli-
ance on with the high-pressure hose de-
tached and operate (max. 2 minutes) until
the water exits the high-pressure connec-
tion without bubbles. Switch off appliance
and reconnect high-pressure hose.

Before Startup

Mount loose parts delivered with appliance

Push the high pressure hose into the
trigger gun until it locks audibly.
Note: Make sure the connection nipple
is aligned correctly.
Check the secure connection by pulling
on the high-pressure hose.
Caution
Dry runs lasting longer than two minutes lead
to damages to the high pressure pump. If the
appliance does not build up pressure within
two minutes, switch it off and proceed as in-
structed in the Chapter "Troubleshooting".
In case of impurities in the supply water, a
3/4" fine water filter must be used.
Connect the high pressure hose to the
high pressure connection of the appli-
ance.
Push the spray lance into the trigger gun
and fasten it by turning it through 90°.
Completely open the water tap.
Insert the mains plug into the socket.
Turn on the appliance "I/ON".
Danger
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 hold-
ing the trigger gun and spray lance firmly.
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 device will switch off again. High pres-
sure remains in the system.
Spray lance with Dirtblaster
For particularly dirty items or areas.
Not suitable for use with detergents.
Spray lance with pressure regulation
Carrying out the most common cleaning
tasks. The work pressure can be stageless-
ly regulated between "Min" and "Max".
