Zoom on the Generac 6712
The Generac 6712, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- precise spot cleaning of hard, unpainted surfaces, reaching elevated areas, and effectively removing stubborn stains
- broad cleaning of hard surfaces, vehicle washing, and surface preparation for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- using cleaning solutions, and rinsing surfaces to remove residue
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
Utilizing an impressive 302cc engine, this machine's triplex pump can deliver a pressure of 3800 PSI (around 63 times stronger than a standard garden hose) and a flow rate of up to 3.2 GPM (values claimed by the manufacturer). Thus, the Generac 6712 achieves a cleaning power of 12160 Cleaning Units.
To initiate the Generac engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 1.7 gallon.
Design & Handling
The Generac 6712's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. The steel frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The handle adds to the 6712 convenience of transport.
Tipping the scales at 134 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. Its 302cc Generac engine, the triplex pump and steel frame add up to a large chunk of the device's weight. However, the incorporation of two 10" pneumatic wheels makes navigating the 6712 less cumbersome, even on uneven terrain.
Main Features
The Generac 6712 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. Due to the absence of a soap dilution feature, users of the Generac 6712 must ensure detergent is correctly diluted prior to use. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
- Pressure hose: For easy organization, the included 50 ft ⌀5/16" high-pressure hose (4000 PSI rating) can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand. The gun features a rotating auxiliary side handle to further improve the comfort of both left and right-handed users.
- Nozzles: In the table below, you can see the 5 included nozzles alongside their respective recommended surface uses.
0° | 15° | 25° | 40° | Soap | |
|---|---|---|---|---|---|
| Concrete, brick, masonry | |||||
