The HD 9/20-4 SXA Plus cold water pressure washer is made of high-quality materials and features an automatic hose reel and the Vibrasoft nozzle for maximum performance and comfort.
A high-pressure washer is a machine, cold or hot water, that forces a powerful jet through a lance and nozzle to degrease and clean vehicles, machinery and surfaces.
What it is for
Used for high-pressure washing of heavily soiled surfaces, vehicles and machinery, for industrial washing of parts, machinery and surfaces and for cleaning vehicles, inside and out.
How to use it
Connect the water supply, observing the minimum flow required, bleed the air and then start; on hot water models, also check the burner fuel. Hold the lance with both hands, start at a distance from the surface and never aim the jet at people, cables or tyres. At the end of the job, release the pressure, check the pump oil and filters and protect the machine from frost.
