  • comprehensive cleaning of hard surfaces, vehicle washing, and readying surfaces for painting

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The NorthStar 157123 in use

The NorthStar 157123

Its triplex pump, which utilizes a 193cc (6.5 hp) engine, may deliver a pressure of up to 3300 PSI (almost 55 times more than a standard garden hose) and a flow of up to 2.5 GPM. Corresponding to these values is a cleaning power of 8250 Cleaning Units.

Starting the Honda GX200 engine of this gas pressure washer involves using a conventional pull-start method.

The pressure washer's steel tank has a maximum capacity of 0.8 gallon for storing gasoline.

Design & Handling

With its wheelbarrow-inspired design, the NorthStar 157123 aims for excellent mobility and stability, enabling effortless maneuvering and dependable performance across diverse environments. Guaranteeing longevity, the robust steel frame offers stability and protects internal components, even when subjected to demanding tasks. The handle adds to the 157123 convenience of transport.

Weighing in at 95 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. The major reasons for its heavy weight are its 193cc Honda GX200 engine, the triplex pump and steel frame. Nevertheless, with its two 10" never-flat wheels, users can manage the 157123 with less difficulty, even over uneven terrain.

Main Features

The NorthStar 157123 in use

The NorthStar 157123

The NorthStar 157123 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Though lacking a dedicated soap tank, the device ensures detergent supply via a siphon hose. The NorthStar 157123 includes an automatic soap dilution mechanism, allowing detergent to be diluted to the ratio of 15:1 with ease. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
  • Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 50 ft ⌀3/8" high-pressure hose to be neatly stored when idle.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: Below, you'll find a table outlining the 4 included nozzles and their recommended surfaces.
