The G-Force II 4040 HG-DD is built to handle weekly use and deliver high flow and pressure in a compact, durable package, suited to large residential and commercial cleaning.
It is powered by a Honda GX390 engine and a GP triplex plunger pump for an output of 15 lpm at 4000 PSI, weighing 42kg. As a direct drive unit the pump is connected directly to the drive shaft of the engine, so pump revolutions match the engine, usually around 3500 rpm, giving a more compact design with fewer components and lighter weight.
The aluminium frame is up to 40% lighter than steel, corrosion resistant to water and chemicals, and carries a lifetime warranty. EZ Start pressure relief allows water to bypass the pump to eliminate pressure build-up, so there is no need to pull the gun trigger while starting. Every Graco pressure washer is backed by a 1-year warranty covering defects in materials and workmanship.
Features
Honda Engine: reliable, powerful and easy to start, with Oil Alert to shut down the engine if oil drops too low and a thermal sensor that prevents the pump overheating in bypass mode.
GP Pump: a reliable GP triplex plunger water pump.
Aluminium Frame: 100% heavy-gauge aluminium, up to 40% lighter than steel, corrosion resistant to water and chemicals, standard on all Graco models and backed by a lifetime warranty.
EZ Start: pressure relief allows water to bypass the pump to eliminate pressure build-up, so there is no need to pull the gun trigger while starting.
Direct Drive: a compact design with fewer components and lighter weight, with the pump connected directly to the engine drive shaft and running at around 3500 rpm.
