Description
Zoom on the NorthStar 157124
In summary, the NorthStar 157124 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- intense cleaning of tough, paintless surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
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
With an impressive 277cc engine, its triplex pump delivers a pressure of 3600 PSI (roughly 60 times more than a standard garden hose) and a flow of up to 3 GPM (values claimed by the manufacturer), resulting in the NorthStar 157124's cleaning power of 10800 Cleaning Units.
The Kohler CH395 engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.
A steel fuel tank with a maximum capacity of 1.9 gallon is used to store gasoline.
Design & Handling
The wheelbarrow design of the NorthStar 157124 grants mobility and stability to the unit. The strong steel tubing frame assures assembly longevity. The handle adds to the 157124 convenience of transport.
With a weight of 118 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. A key role in its final weight is played by its 277cc Kohler CH395 engine, the triplex pump and steel tubing frame. However, the unit is manipulated smoothly thanks to its two 10" never-flat wheels, which play a key role in its maneuverability.
Main Features
Along with the NorthStar 157124 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is diluted with a 15:1 ratio by the NorthStar 157124's automatic soap dilution mechanism. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.
15° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | Suitable | Suitable | Suitable | Suitable |
| Siding, gutters, house | Use with caution | Use with caution | Suitable | Suitable |
| Fencing, deck, patio | Use with caution | Use with caution | Suitable | Suitable |

- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation), a low oil protection and a thermal relief valve (which helps to prevent internal pump damage).
- Accessories: Included with the NorthStar 157124 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as spray gun, soap hose, wand and pressure hose.
- Emissions: The NorthStar 157124 is EPA-approved and CARB-compliant. Therefore, the sale and purchase of this pressure washer is permitted in all of the 50 states, including California.

- The NorthStar 157124 with its 3600 PSI achieves a lower pressure value, compared to other gas-powered pressure washers in the $900-1000 price range.
