§ FAQ

What makes the Honda GX270 engine in the DXPW4035 suitable for professional use?

The Honda GX270 is a 269cc commercial-series OHV engine rated at approximately 8.4 HP. It features an overhead valve design for cooler operation, a large fuel capacity of 1.4 gallons, and Honda's low-oil alert system to prevent engine damage during extended run times.

Is the DXPW4035 suitable for stripping paint or removing graffiti?

Yes. At 4,000 PSI and 3.5 GPM (14,000 cleaning units), the DXPW4035 has sufficient pressure and flow to strip paint, remove graffiti, and prepare surfaces for repainting. Use the 0° or 15° nozzle for maximum impact.

How long is the hose on the DXPW4035?

The DXPW4035 includes a 50 ft. 3/8-inch steel-braided high-pressure hose, giving considerable reach for cleaning large driveways, buildings, and equipment without moving the unit repeatedly.

Can I connect a longer hose to the DXPW4035?

Yes. Additional DEWALT-compatible 50 ft. hose extensions can be connected to the DXPW4035. However, each additional hose section slightly reduces effective pressure at the nozzle.

What type of pump does the DXPW4035 use?

The DXPW4035 uses an AAA industrial triplex plunger pump, which offers longer service life than axial cam pumps thanks to its three-piston design that distributes wear across multiple components and runs cooler under load.

What warranty does the DXPW4035 carry?

The DXPW4035 is backed by a 5-year limited warranty. The Honda GX270 engine carries a separate Honda commercial engine warranty. DEWALT also offers a 90-day money-back guarantee.
