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 as-
bestos- 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 pres-
sure washer is
only allowed to be
connected with
the drinking water
mains, when an appropriate
backfl ow preventer has been
installed, Type BA according
to EN 1717. The backfl ow pre-
venter can be ordered under
number 106411177. The length
of the hose between the back-
fl ow preventer and the high
pressure washer must be at
least 10 metres to absorb pos-
sible pressure peaks (min diam-
eter 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 gun
(7a)
(see illustration at the end
of this manual) :
The spray gun features a lock-
ing device. When the pawl is
activated, the spray gun 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.
