Compact, horizontal petrol-powered cold water high-pressure cleaner for go-anywhere applications independent of an electricity supply. The compact engine-pump unit is mounted in a sturdy, portable tubular frame. The unit’s compact dimensions ensure trouble-free transportation between sites. Its single cylinder four-stroke air-cooled engine is easily started with the pull starter. The pump’s brass cylinder head and stainless-steel valves are designed for tough professional applications and ensure a long service life. The infinitely variable detergent metering ensures exactly the right concentration for the job and therefore helps reduce chemical consumption. A built-in safety valve reliably protects the unit against excessively high pressures. The thermal sensor on the pump’s cylinder head shuts down the engine automatically if the temperature exceeds a certain limit during closed circuit operation (with the trigger gun closed). Can be easily loaded for transport, due to the sturdy all-round tubular frame.
