Description

Graco G-Force II 4240 KA-DD 4200 PSI Pressure Washer 

The Graco G-Force II™ 4240 KA-DD is a high-performance petrol pressure washer built for residential remodelers, paint contractors, and property maintenance professionals. Engineered to deliver exceptional durability for medium-to-heavy cleaning schedules (10 to 20 hours per week), it unleashes a powerful 4200 PSI of stripping force combined with a steady 15 LPM water flow to clear away grit, grime, and scaling paint instantly.

By utilizing an ultra-compact Direct Drive (DD) design, the water pump is coupled directly to the engine's primary drive shaft. This layout matches the pump's RPM directly to the engine (around 3500 RPM), completely removing the need for drive belts, pulleys, or extra mechanical linkages. The result is an exceptionally lightweight 47 kg machine that offers maximum portability on the jobsite and loads into trucks with minimal effort.

Features

  • The Engine (Kohler® Command Pro CH440): Powered by a commercial-grade, multi-use Kohler CH440 engine. Features a heavy-duty forged steel crankshaft, cast-iron cylinder bore lining, and an advanced Quad-Clean™ 4-stage cyclonic air filtration system that forces airborne dust and paint overspray particles out before they can contaminate the combustion chamber.
  • The Water Pump (Annovi Reverberi® Triplex Plunger Pump): Built with a professional-tier AR Triplex plunger pump featuring a forged brass manifold. This composition disperses thermal energy far more effectively than standard steel parts, reducing internal heat buildup to protect your high-pressure packings from cracking.
  • 100% Lightweight Aluminum Chassis: Constructed from Graco’s signature structural aluminum frame. It is naturally resistant to rust, chemical degradation, and water corrosion while remaining up to 40% lighter than heavy steel-frame alternatives.
  • EZ Start™ Pressure Relief Unloader: Features an adjustable pressure unloader integrated directly into the pump head. Its EZ Start loop bypasses high-pressure water buildup during starting sequences, allowing the recoil pull-start to glide freely without requiring the operator to clip or squeeze the spray gun trigger.
  • Heavy-Duty 19mm Steel Axles: Built over professional-grade 19mm steel axle shafts that hold up under jobsite shocks and rough transportation, keeping the frame perfectly square and the pneumatic tires rolling smooth.
  • Downstream Chemical Injector: Arrives pre-packaged with an integrated detergent siphoning kit, letting you pull downstream soaps and exterior cleaning solutions straight from the bottle into your low-pressure spray pattern.
