Description

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

The Graco G-Force II™ 4240 HA-DD is a premium, high-power petrol pressure washer engineered specifically for large-scale residential painters, commercial renovation contractors, and property maintenance teams. Built to handle heavy workloads between 20 to 30 hours per week, it generates a blistering 4200 PSI of cutting force coupled with a steady 15 LPM fluid delivery to clean up stubborn jobsites rapidly.

Utilizing an ultra-efficient Direct Drive (DD) design, the water pump is coupled directly to the engine's primary drive shaft. This design eliminates unnecessary belts and pulleys, resulting in an incredibly compact, highly reliable, and exceptionally lightweight package. Weighing in at a nimble 46 kg, it delivers industrial-strength performance while remaining easy to load, lift, and transport in utility vehicles.

Features

The Engine (Honda GX390): Driven by the legendary commercial-grade Honda GX390 engine, celebrated for easy starting, smooth overhead valve (OHV) output, and built-in Oil Alert™ technology that automatically shuts down the motor to prevent catastrophic damage if oil levels run low.
The Water Pump (Annovi Reverberi Triplex Plunger Pump): Features a professional-tier AR Triplex plunger pump designed for high mechanical duty cycles. It includes an integrated thermal sensor that prevents the pump from overheating while idling in bypass mode.
100% Heavy-Gauge Aluminum Frame: Constructed from Graco’s signature structural aluminum frame chassis, which is up to 40% lighter than standard steel frames and naturally immune to water, chemical, and rust corrosion.
EZ Start™ Pressure Relief System: Eliminates high-pressure compression resistance during the pull-start sequence by bypassing water loops. You can start the machine safely without needing to manually hold or squeeze the spray gun trigger.
Adjustable Integrated Unloader: Features a variable pressure governor built directly into the pump housing, allowing operators to fine-tune the high-pressure water stream down to match more delicate cleaning applications.
Heavy-Duty Contractor Delivery Kit: Arrives field-ready with a 15-meter (50 ft) non-marking grey braided hose, dual-ended quick-connect hardware couplings, and a heavy-duty 91 cm (36 in) steel lance.
