This Generac Professional Grade Pressure Washer’s 12-inch pneumatic wheels and professional-grade spray gun complement the powerful 420cc Generac OHV horizontal-shaft engine and professional-grade triplex pump. With a long 50-foot non-marring rubber hose, you’ll be ready to take on even the biggest cleaning jobs. With features like ceramic-coated pistons, the professional-grade triplex pump is designed for rugged duty and long life. The powerful 420cc Generac OHV engine provides maximum cleaning performance and reliability, and has a low-oil shutdown to protect the engine. With the oversized pneumatic tires, you can take the pressure washer over even the most rugged terrain around the house, at work, or on the farm. The folding handle takes up even less space in your garage or shed during storage and helps you transport the pressure washer even more easily. The pressure control valve provides complete control of water pressure for all applications. The brass quick change fittings help you make hose connections even more quickly and effortlessly. The durable, non-marring, 50-foot steel-reinforced hose will not leave scuff marks. The professional spray gun with adjustable side handle provides precise control and cushion grip. The easy-to-pull trigger reduces fatigue and improves comfort during extended use. The welded roll cage frame protects the engine and pump while providing grab bars for easy lifting. The five Quick Click nozzle tips include 0°, 15°, 25°, 40°, and soap. The detergent siphon hose allows you to use a variety of cleaning solutions to improve results. The Generac Professional Grade Pressure Washer offers tough cleaning performance for any jobsite.
