jet of the high-pressure nozzle
Never direct the cleaning jet of the
high-pressure cleaner or hot water
high-pressure cleaner onto the marked
components.
Never aim the cleaning jet of high-
pressure cleaners or hot water high-
pressure cleaners on electrical or
electronic components.
Never aim the cleaning jet of the high
pressure cleaner directly on lubrication
points, bearings, rating plates, warning
