Overview

The 4512-40KA is a portable commercial hot water pressure washer that delivers 4.5 GPM at 4000 PSI, powered by a 14 HP Kohler Command Pro engine with electric start and a high-output charging system. A fortified AR RKV pump with nickel-plated manifold handles the water end, while a diesel-fired Beckett burner heats through a schedule 80 coil with a one-piece molded insulation combustion chamber and stainless steel wrap. Hot water is what cuts grease, oil, and heavy grime that cold units leave behind, making this a fit for fleet washing, kitchen exhaust, and heavy equipment work. It rides on a powder-coated steel roll-cage frame with a lifting hook and 13" flat-free tires, and every unit ships factory assembled and tested in the USA, ready to operate.

Frequently asked questions

No — a marine-grade battery box is included, but the battery itself is not. Add a standard 12V battery and the Kohler Command Pro's electric start and high-output charging system are ready to go.

It uses two fuels: gasoline for the 14 HP Kohler engine that drives the pump, and diesel for the Beckett burner that heats the water. The burner draws from the built-in 8-gallon poly diesel tank with a fuel filter.

Yes — every unit is completely factory assembled and tested in the USA and delivered ready to operate. You only need to add a battery, fill the gasoline and diesel tanks, and connect your water supply.

No, this model is not for sale in California. If you're in California, call us and we can point you to a compliant alternative in the same PSI and GPM range.
