safety only use original spare
parts from the manufacturer
or approved by the manufac-
turer.
 High pressure hoses, fi ttings
and couplings are important
for the safety of the appli-
ance. Only use hoses, fi ttings
and couplings recommended
by the manufacturer.
 Do not use the appliance
if a supply cord or impor-
tant parts of appliance are
damaged, e.g. safety device ,
high pressure hose and trig-
ger gun.
 The appliance is intended to
clean cars and garden etc..
 Appropriate ear protection
has to be used.
 Never use the machine in
an environment where there
could be a danger of explo-
sion. If any doubt arises,
please contact the local
authorities.
 It is not allowed to clean
asbestos- containing surfaces
with high pressure.
 This high pressure washer
must not be used at tempera-
tures below 0°C.
WARNING!
Inadequate extension cables
can be dangerous. Cables on
drums should always be com-
pletely unwinded to prevent the
cable from overheating.
If an extension cable is used,
the plug and the socket must be
waterproof and comply with the
below-mentioned requirements
for length and cable dimen-
sions.
1.0 mm² max. 12.5 m
1.5 mm² max. 20 m
2.5 mm² max. 30 m
 If the electric cable is
damaged, it must be re-
placed by the manufacturer
or his service agent or simi-
larly qualifi ed person in order
to avoid a hazard.
Mains power connection
The following should be ob-
served when connecting the
high pressure washer to the
electric installation:
 The electric installation shall
be made by a certifi ed elec-
trician and comply with IEC
364.
 It is recommended that the
electric supply to this appli-
ance should include either a
residual current device that
will interrupt the supply if the
leakage current to earth ex-
ceeds 30 mA for 30 ms.
Water connection
 Connection to the public
mains according to regula-
tions.
 Inlet hose can be connected
to the water mains with a
max. inlet pressure of 10
bars.
This high pressure washer is
only allowed to be connected
with the drinking water mains,
when an appropri-
ate backfl ow pre-
venter has been
installed, Type BA
according to EN
1717. The back-
fl ow preventer
can be ordered under number
106411177. The length of the
hose between the backfl ow
preventer and the high pres-
sure washer must be at least
10 metres to absorb possible
pressure peaks (min diameter
½ inch).
Operation by suction (for ex-
ample from a rainwater vessel)
is carried out without backfl ow
preventer. Recommended suc-
tion set: 126411387.
As soon as water has fl own
through the BA valve, this water
is not considered to be drinking
water any more.
IMPORTANT! Only use wa-
ter without any impurities. If
there is a risk of running sands
in the inlet water (i.e. from your
own well), an additional fi lter
should be mounted.
Safety devices
 The unloader valve can re-
duce pressure if it exceeds
pre-set values.
Locking device on spray handle
(7a) (see illustration at the end
of this manual):
The spray handle features a
locking device. When the pawl
is activated, the spray handle
cannot be ope rated.
Thermal sensor:
A thermal sensor protects the
motor against overloading. The
machine will restart after a few
minutes when the thermal sen-
sor has cooled.
