Description

Honda® GX390 engine delivers 389ccs of cleaning power. Adjustable AR triplex pump allows user to adjust pressure between 300-4200 PSI. 4.0 Max GPM per PWMA PW101-2010. Fully welded durable frame. 50’ flexible hose for fewer kinks, easier storage and extended reach.

Zoom on the Husqvarna HH42

The Husqvarna HH42 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, unpainted surfaces and high-reach cleaning
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate surfaces
  • use of detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

Using a powerful 389cc engine, its triplex pump delivers a pressure of up to 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values as per PW101-2010). Together, the values result in a cleaning power of 16800 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX390 engine.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.6 gallon.

Design & Handling

The wheelbarrow design of the Husqvarna HH42 grants mobility and stability to the unit. The robust welded steel frame guarantees longevity of the assembly. The handle adds to the HH42 convenience of transport.

With a weight of 145 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The main contributors to its weight are its 389cc Honda GX390 engine, the triplex pump and welded steel frame. However, its two 13" pneumatic wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.

Main Features

The Husqvarna HH42's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: A neat storage for the included 50 ft high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
