The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.

Power & Run Time

The Firman T04073

The Firman T04073 delivers 120/240V and boasts with a tri-fuel technology enabling it to utilize gasoline, propane, or natural gas. When powered by gasoline, it achieves a running wattage of 4,000W and a peak wattage of 5,000W. Upon using propane, it gains 3,600 rated watts and 4,500 peak watts. Its operation with natural gas provides 3,200W of rated wattage and 4,000W of starting wattage.

At a noise rating of 67 dBA (less noisy than background music), this generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).

The T04073, with a fuel capacity of 5 gallons, reaches a run time of around 14 hours at 50% load utilizing gasoline (fuel consumption around 0.36 GPH). Alternatively, it can reach a run time of around 9 hours (on a 20 lbs tank - propane consumption around 0.52 GPH) with propane.

The powering of sensitive electronic devices with the T04073 is not recommended due to its relatively high THD (<14%).

Outlets

The control panel is equipped with the following 4 AC outlets:

Though it may not be labeled as 'RV Ready,' this Firman generator offers the benefit of hassle-free RV connectivity through its L5-30R receptacle, allowing you to easily power your RV with the assistance of an L5-30P to TT-30R adaptor (included). Besides, since it boasts a twist-lock L14-30R receptacle, the T04073 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.

Portability

Measuring L29.8 x W27.5 x H26.1 in, the classic open frame construction of the Firman T04073 provides stability while enabling convenient maintenance access to components and adequate air cooling. The device has been designed for tough environments and demanding outdoor use.

While weighing 123.4 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The T04073's control panel

The control panel of the T04073 is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings, aiding in monitoring its status and activity.

In addition to this info, a light indicator shows you if the generator is ready.

The built-in fuel gauge of the generator ensures simple and quick gas level assessments.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

The T04073 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman T04073 ships with supplementary accessories: RV adapter, propane hose, cover, funnel, tool kit and oil.
