Power
The DeWalt DH4240B
With an impressive 389cc (11.7 hp) engine powering it, the triplex pump of this unit are capable of achieving a pressure of 4200 PSI (approximately 70 times greater than that of a standard garden hose) and a flow rate of up to 4 GPM (CETA-certified values). Corresponding to these values is a cleaning power of 16800 Cleaning Units.
Starting the Honda GX390 engine of this gas pressure washer involves using a conventional pull-start method.
Fuel for the pressure washer is housed in a tank capable of holding up to 1.6 gallon of gasoline..
Design & Handling
Characterized by its wheelbarrow layout, the DeWalt DH4240B provides improved mobility and stability, facilitating easy movement and steadfast operation for effective cleaning results. The welded steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The handle adds to the DH4240B convenience of transport.
At 145 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. Its 389cc Honda GX390 engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the incorporation of two 13" pneumatic wheels makes navigating the DH4240B less cumbersome, even on uneven terrain.
