Safety instructions

DANGER
– Do not use high pressure cleaners
when there has been an oil spill; move
the appliance to another spot and avoid
any sort of spark formation.
– Do not store, spill or use fuel in the vi-
cinity of open flames or appliances such
as ovens, boilers, water heaters, etc.
that have an ignition flame or can gen-
erate sparks.
– Keep even mildly inflammable objects
and materials away from the silencer (at
least 2 m).
– Do not start the engine without the si-
lencer; check, clean and replace, if re-
quired, the silencer at regular intervals.
– Do not use the engine in forest, bushes
or grassy areas without fitting a spark
receiver at the exhaust.
– Except for setting jobs, do not run the en-
gine when the air filter is removed or there
is no cover over the suction support.
– Do not make any adjustments to the reg-
ulator springs, regulator bars or other
parts that can bring forth an increase in
the engine speed.
– Risk of burns! Do not touch hot silenc-
ers, cylinders or radiator ribs.
– Do not put hands or feet close to mov-
ing or rotating parts.
– Risk of poisoning! The appliance should
not be operated in closed rooms.
General notes on safety

– The heating appliance of the machine is
an ignition plant. All national laws and
regulations about heating systems must
also be followed.
High pressure hose
DANGER
Risk of injury!
– Only use original high-pressure hoses.
– The high-pressure hose and the injec-
tion system must be suitable for the
maximum operating pressure given in
the Technical Data.
– Avoid contact with chemicals.
– Check the high-pressure hose daily.
Do not use hoses with kinks.
Stop using the high-pressure hose if the
external wire layer is visible.
– Do not use the high-pressure hose any-
more if the winding is damaged.
– Lay the high-pressure hoses in such a
way that no vehicle can drive over it.
– Do not use high-pressure hoses that
have been driven over, kinked, pressed
or bent even if there is no externally vis-
ible damage.
– Store the high-pressure hoses in such a
way that they are not subject to any me-
chanical load.

Safety Devices

Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.
Water shortage safeguard
The safety mechanism against lack of wa-
ter prevents the heater from over-heating
when there is no water. The burner oper-
ates only when there is adequate water
supply.
Overflow valve
– If the hand spray gun is closed, the
overflow valve opens and the high pres-
sure pump diverts the water back to the
pump suction side. Thus the permissi-
ble working pressure is not exceeded.
– The overflow valve is set by the manu-
facturer and sealed. Setting only by
customer service.
