carry out a visual check of all the
major components.
CAUTION!
High-pressure water jets can
be dangerous if misused. The
jet must not be directed at
persons, animals, live electri-
cal equipment or the cleaner
itself.
Wear appropriate protective
clothing and eye protection.
Do not direct the jet towards
yourself or towards other per-
sons in order to clean clothes
or footwear.
During operation of the cleaner,
recoil forces are produced at the
gunvalve and spray lance and,
when the spray lance is held at
an angle, a torque is also cre-
ated. The gunvalve and spray
lancemust therefore be held
fi rmly in both hands.
Do not use the cleaner when
other people without protec-
tive clothing are in the working
area.
Check that cleaning will not
result in dangerous substances
(e.g. asbestos, oil) being washed
off the object to be cleaned and
harming the environment.
Do not clean delicate parts
made of rubber, fabric, etc. with
the 0° jet. Keep some distance
between high pressure nozzle
and surface in order to prevent
the surface from damage.
Do not use the high-pressure
hose for lifting loads.
NOTE!
The maximum permissible work-
ing pressure and temperature
are printed on the high-pressure
hose.
Do not use the cleaner if the
power cord or high-pressure
hose is damaged.
Ensure adequate air circulation.
Do not cover the cleaner or oper-
ate it in inadequately ventilated
rooms!
1) Options / model variants
Store the cleaner where
it will not be exposed to
frost or use antifreeze
liquid!
Never operate the cleaner with-
out water. Even brief shortages
of water result in severe damage
to the pump seals.
Water connection
This high pressure
washer is only al-
lowed to be con-
nected with the
drinking water
mains, when an appropriate
backflow preventer has been
installed, Type BA according
to EN 1717. If the back fl ow
preventer hasn't been supplied,
one can be purchased from your
dealer. The length of the hose
between the backfl ow preventer
and the high pressure washer
must be at least 12 metres (min
diameter 3/4 inch) to absorb pos-
sible pressure peaks. Operation
by suction (for example from
a rainwater vessel) is carried
out without backfl ow preventer.
Contact your dealer for suction
set recommendations.
As soon as water has flown
through the BA valve, this water
is not considered to be drinking
water any more.
Operation
Keep cabinet and service door
closed during operation.
CAUTION!
Unsuitable extension cords
can represent a source of
danger. Always unwind cord
from the reels completely to
prevent the power cord over-
heating.
Connectors and couplings of
extension cords must be water-
tight.
Extension cords are not recom-
mended, however if necessaray
refer to the following recommen-
dations:
Cable length Cross section
m
< 16 A
up to 20 m ø1.5mm²
20 to 50 m ø2.5mm²
Do not damage the power cord
(e.g. by driving over it, pulling or
crushing it).
Disconnect the power cord by
grasping the plug only (do not pull
or tug the power cord).
CAUTION!
Unsuitable fuels (e.g. gasoline)
must not be used as they can
explode and catch fi re.
Use clean fuel only, free of mois-
ture and contamination. Contact
your dealer for fuel source and
type recommendations.
If the machine is to be operated at
fuel stations or in other potentially
hazardous areas, the machine
may only be employed outside
the hazard areas defi ned in the
German „Technical Guidelines
for Infl ammable Fluids" applica-
ble at the point of use due to the
potential explosion hazard posed
by the burner.
If the machine is to be operated
indoors, the local building regu-
lations must be observed for the
discharge of the exhaust fumes
into the atmosphere. Ensure an
adequate supply of fresh air.
If the machine is to be connected
to a fl ue gas stack, then local
building regulations must be ob-
served. We will be glad to provide
tips for connection systems, on
request.
CAUTION!
Beware of hot water and
steam discharge up to
0
150 C when operating in
steam stage.
CAUTION!
Do not touch or cover the
exhaust. Risk of burns
and fi re.
Do not touch, cover or place
