Product description
Mi-T-M's HSP Series is one of the most popular portable hot-water pressure washers on the market - a 389cc Honda GX390 driving an AR triplex pump through a top-fired, powder-coated heat exchanger with an Electro-Magnetic Firing (EMF) system and diesel/kerosene burner. It raises solution 150F above ambient (up to ~200F outlet) to strip grease, oil and baked-on soils that cold water can't touch. Center-balanced reinforced steel frame, 13-inch flat-free tires, 5.5-gal burner fuel tank.
- Hot water to ~200F strips grease, oil, gum and baked-on soils
- 294,000 BTU diesel/kerosene burner with EMF firing
- 389cc Honda GX390 + AR triplex pump
- Preset stainless/brass unloader, forged brass manifold, LP detergent injector
- Reinforced steel frame with center-balanced lift, 13" flat-free tires
- Optional adjustable thermostat (98-248F), hour meter, electric start
- 3 yr coil / 7 yr AR pump warranty
Receiving — do not sign clean
- Count the pieces against the bill of lading before the driver leaves. A machine, its batteries and its accessories can ship as separate items.
- Walk the pallet. Check the shrink-wrap, the crate corners and the machine itself — forks go through crates more often than anyone admits.
- Photograph any damage before you sign. Once the driver has your signature the photographs are worth much less.
- Write the damage on the delivery receipt. A clean signature on a damaged pallet is what makes a freight claim hard. Then call 1-888-287-3732 the same day.
