View larger Karcher's most advanced gasoline-powered pressure washer, the G 4000 OH is German engineered from the ground up and designed for heavy-duty use. No job is too difficult for the G 4000 OH. It has many industry-leading features, such as a 390cc Honda GX Series engine and Karcher's high-performance industrial-grade pump with brass pump head.
Introducing Karcher's innovative remote pressure control, exclusive to the G 4000 OH. Simply turn the remote pressure control in either direction to increase or decrease the amount of water pressure and volume right on the wand. Instead of having to go to the pressure washer pump or change the spray nozzle each time you want to change the pressure, simply dial up the desired amount on the remote pressure control. This feature allows you to work continuously without having to stop each time you want to adjust the water pressure.
Other advanced features the professional will appreciate on the top-of-the-line unit include a stainless-steel spray wand, 12-inch pneumatic tires with metal wheels, a 50-foot rubber hose, and a complete set of Karcher's patented pro-style quick-connect nozzles. The G 4000 OH is the perfect solution for those who demand the absolute highest level of cleaning performance.
