Key Features

Powerful Tri-Fuel Performance

Choose the fuel source that best suits your needs. The T08072 delivers different power levels depending on the fuel used:

Fuel Type	Starting Watts	Running Watts
Gasoline	10,000 W	8,000 W
Propane (LPG)	9,050 W	7,250 W
Natural Gas (NG)	6,900 W	5,500 W

Durable 439cc FIRMAN Engine

The 439cc 4-stroke OHV FIRMAN engine features a durable cast-iron cylinder sleeve and Phoenix Fat Head Block design to support efficient operation and long-term performance.

Convenient Starting System

Start the generator with the electric-start system or use the recoil backup when needed.

Extended Gasoline Runtime

The 8-gallon (30.3-liter) heavy-duty steel fuel tank provides up to 12 hours of runtime on gasoline, according to the supplied specifications. A built-in fuel gauge helps you monitor the remaining fuel level.

Automatic Voltage Regulation

The Automatic Voltage Regulation (AVR) system helps maintain stable voltage. The integrated 3-in-1 Data Minder displays voltage, frequency (hertz), and running hours for convenient performance monitoring.

CO Alert Safety Technology

Built-in CO Alert technology detects unsafe carbon monoxide levels and automatically shuts down the generator when dangerous conditions are detected. Always operate the generator outdoors, away from doors, windows, and vents. Never operate it inside a home, garage, or other enclosed or partially enclosed space.

Transfer-Switch-Ready Design

Designed for home backup applications, the T08072 includes a 120/240V, 50A outlet and a multi-feature control panel with attached outlet covers. Use an appropriately rated transfer switch and have the installation completed by a qualified professional.

Convenient Portable Design

The included 10-inch flat-free wheel kit and U-shaped folding handle with grip make moving the generator more convenient.
