§ FAQ

What engine is in the DXPW61373?

The DXPW61373 is powered by a DEWALT CRX340 338cc OHV 4-stroke air-cooled engine with a low-oil shutdown system. At 338cc displacement, this engine provides ample torque to drive the triplex pump at 4,000 PSI even under continuous load.

What is special about the AAA triplex pump with brass head on the DXPW61373?

The brass pump head resists corrosion from minerals and detergents far better than aluminum heads, extending the service life of the pump. Combined with the triplex plunger design, the pump delivers longer operational life and more consistent pressure compared to axial cam alternatives.

Is the DXPW61373 available in California?

The DXPW61373 is not for sale in California due to California small-engine emissions regulations. Customers in California should contact DEWALT or local retailers for CARB-compliant alternatives.

How much fuel does the DXPW61373 hold?

The DXPW61373 has a 1.6-gallon fuel tank, which provides substantial run time before refueling—ideal for extended commercial cleaning sessions.

How does the DXPW61373 compare to the DXPW4035?

Both machines produce 4,000 PSI at 3.5 GPM with a triplex pump and 50 ft. hose. The DXPW4035 uses a Honda GX270 269cc engine while the DXPW61373 uses a DEWALT 338cc engine. The larger DEWALT engine offers more displacement and torque, but the Honda GX270 has a widely recognized service network.

What frame and tires does the DXPW61373 use?

The DXPW61373 is built on a welded steel frame with a powder-coated finish for corrosion resistance. It rolls on 12-inch pneumatic tires, which are larger than those on lighter models, helping absorb vibration and navigate rough surfaces more easily.
