The electric start feature eliminates the hassle of manual pull cords—especially important in cold weather or extended jobsite conditions. A 55AH marine-grade AGM battery is included, delivering long-lasting performance in rugged outdoor environments. Honda’s reputation for dependability makes this engine an ideal choice for anyone who needs a washer that starts easily and runs hard all day.

The WJHW4013HA is framed by a powder-coated steel chassis, designed to handle rough terrain, long workdays, and harsh conditions. A roll cage design protects the core components—engine, pump, and burner—while offering easy access for service, fueling, or maintenance.
Mounted on four 13-inch flat-free tires, the unit moves smoothly across gravel, dirt, grass, or pavement. Whether on a jobsite or in a remote field, the wheels ensure excellent mobility without the risk of downtime due to punctures.
The frame also includes built-in mounting brackets for truck or trailer installations. Simply remove the wheels and bolt it down for a more permanent setup. A central lift point is also integrated into the design, making it easy to crane-lift the unit onto service vehicles or loading docks.
