– 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
engine when the air filter is removed or
there is no cover over the suction sup-
port.
– Do not make any adjustments to the
regulator springs, regulator bars or oth-
er 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.
– Do not use unsuitable fuels, as they
may be dangerous.
Safety devices serve for the protection of the
user and must not be put out of operation or
bypassed with respect to their function.
– 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.
