–
Never draw in fluids containing
solvents or undiluted acids and
solvents (e. g., gasoline, heating oil,
paint thinner or acetone). These
substances damage the materials
used in the machine. The spray is
highly combustible, explosive and
poisonous.
Ensure you always have a firm and safe
footing.
Beware of slipping on ice, water, snow
or uneven ground!
Keep the high-pressure cleaner as far
away as possible from the object being
cleaned.
Do not cover the machine and ensure
adequate motor ventilation.
No smoking when working with or near
the machine - risk of fire! The fuel tank
may give off inflammable vapors.
In hot-water operation, do not touch
metal parts of the spray attachment and
the heat exchanger – Danger of burns!
Do not lean over the exhaust gas outlet
and keep all parts of the body well clear
of the exhaust gas outlet. Do not cover
the exhaust gas outlet – Risk of burns
and explosions!
Do not direct the high-pressure jet
against animals.
Do not direct the high-pressure jet onto
places you cannot see.
Children, animals and bystanders must
remain at a distance.
Hazardous substances (e. g., asbestos
or oil) must not be allowed to escape into
the environment unchecked when
working with the machine. The
applicable environmental regulations
must be observed without fail.
Surfaces of asbestos cement must
never be cleaned with a high-pressure
jet. Hazardous, breathable asbestos
fibers may be released in addition to the
dirt. The danger is greatest when the
washed surface has dried.
Delicate parts made of rubber, fabric
or similar materials must not be cleaned
with a pencil jet, e. g., from the rotary
nozzle. Maintain a sufficient distance
between the high-pressure hose and the
surface when cleaning to avoid any
damage to the surface being cleaned.
The trigger on the spray gun must move
easily and automatically return to its
starting position when released.
Hold the spray attachment firmly with
both hands in order safely to withstand
the kickback force and additional torque
produced when using spray
attachments with angled spray lance.
Ensure that the power cord and the high-
pressure hose are not damaged by
being driven over, squashed or pulled;
protect them against heat and oil.
Do not touch the power cord with the
high-pressure jet.
If the machine is subjected to unusually
high loads for which it was not designed
(e.g., heavy impact or a fall), always
check that it is in good condition before
continuing work - refer also to the
chapter "Before starting work". Also
make certain that the safety
mechanisms are working properly.
Never continue using a machine that is
not in perfect working order. Consult a
servicing dealer if in doubt.
Before leaving the machine: Switch off
the machine – unplug the power cord.
Safety equipment
When the safety equipment is activated,
excessive pressure is returned to the
intake side of the pump via a safety
The plug must be discon -
nected immediately if the
cord is damaged – dan
-
ger of electrocution!
Never direct the high-
pressure jet or water
hose against the machine
itself or against other
electrical appliances and
equipment – danger of
short-circuiting!
Never direct the high-
pressure jet or water
hose against electrical
equipment, connections
and power cords – dan -
ger of short-circuiting!
Never direct the high-
pressure jet against your -
self or other people, not
even to clean clothing or
shoes – risk of injury!
Toxic exhaust gases are
produced in hot-water
operation; these gases
may be odorless and
invisible. Never operate
the machine in enclosed
or poorly ventilated
rooms.
