What it is
The HD 9/23 G Kärcher is a cold water pressure washer from Kärcher, the world leader in professional cleaning technology, headquartered in Winnenden (Germany). The HD 9/23 G cold water pressure washer with Honda petrol engine can work independently. Ideal for outdoor and on-the-move work, even in adverse outdoor conditions.
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.
