IMPORTANT: Read this instruction manual before you start up your high pressure washer for
the first time.
This machine is a hot water high pressure washer producing a water jet under high pressure and of a high
temperature which is why severe injuries and scalding can occur if the safety precautions are not observed.
Therefore a complete understanding of the contents of this instruction manual is required in order to pre-
vent injuries to yourself, objects and persons near-by, and the machine itself.
