FIRMAN H07552 9400W Dual Fuel Portable Generator

Product Overview

The FIRMAN H07552 Dual Fuel Portable Generator is a versatile and high-capacity power solution engineered for diverse applications, including home emergency backup, professional construction job sites, RV travel, and marine use. Driven by a powerful 439cc 4-stroke engine, this unit offers the convenience of dual-fuel capability, allowing operators to switch seamlessly between gasoline and propane (LPG) depending on fuel availability or cost.

Designed for both power and reliability, the H07552 provides robust starting power for high-draw inductive loads like central air conditioners and power tools, while maintaining stability through an integrated Automatic Voltage Regulator (AVR). Its durable architecture—featuring a cast-iron engine sleeve and heavy-duty frame—is matched with user-friendly mobility enhancements, such as an all-terrain wheel kit and a cushioned transport handle.

Key Features & Benefits

• Dual-Fuel Flexibility: Operates on either gasoline or propane, providing a critical safety net during supply shortages and allowing for cleaner, longer-term storage of fuel via LPG.

• High-Capacity Performance:

  • Gasoline: 9,400 Starting Watts / 7,500 Running Watts

  • Propane (LPG): 8,450 Starting Watts / 6,750 Running Watts

• Extended Operational Range: The massive 8-gallon gasoline tank facilitates up to 12 hours of continuous operation at 50% load, ideal for overnight use or long work shifts.

• Engine Durability: Built with a high-performance 439cc engine featuring a cast-iron cylinder sleeve to reduce wear and extend the overall lifespan of the generator.

• Safety & Stability Systems: Outfitted with an Automatic Voltage Regulator (AVR) to protect sensitive electronics from voltage spikes and an automatic low-oil shutdown system to prevent internal engine damage.

• Comprehensive Outlet Array: Features a versatile panel with GFCI-protected 120V outlets, a high-amperage 50A 120/240V outlet, and a 30A 120V twist-lock outlet to handle a wide range of appliance plugs.

Safety & Operational Guidelines

Important Warning: Portable generators produce carbon monoxide, a colorless and odorless gas that can be fatal. Never operate this generator inside a home, garage, basement, or any enclosed space. Always place the unit outdoors in a well-ventilated area, at least 20 feet away from windows, doors, and air intakes.

Dual-Fuel Tip: Propane (LPG) does not degrade over time, making it an excellent choice for long-term emergency fuel storage. We recommend keeping a spare tank on hand, as it prevents the carburetor gumming issues often associated with gasoline left in storage for extended periods.
