Overview

This is a Honda GX390 electric-start, skid-mount cold-water pressure washer rated at 4200 PSI and 4.0 GPM, driven by an industrial AR pump through a 3-V cog belt. The belt-drive setup runs the pump at low RPM for longer service life and less downtime than a direct-drive unit. The GX390 carries electric start with a marine-grade battery box, a recoil starter as backup, and low-oil shutdown. It ships on a heavy-duty steel skid frame with a corrosion-resistant finish, built for contractors who need a durable, high-output machine for daily field work. Battery not included; not for sale in California.

Frequently asked questions

It comes with the heavy-duty gun and wand with quick-connects, a 50' high-pressure hose with QC couplers, a 10% chemical injector with QCs, four color-coded stainless steel QC spray nozzles, one brass QC chemical nozzle, a stainless steel inlet filter with external bypass, and the marine-grade battery box. The battery itself is not included.

It's a belt-drive unit, using a 3-V cog belt system to run the AR pump. Belt drive turns the pump at lower RPM than direct drive, which reduces heat and wear and generally extends pump service life for daily, high-hour field use.
