The Firman H08051 generator features 10,000 starting Watts and 8,000 running watts (9050/7250 LPG). Power is supplied by our Max Pro Series 439cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the H08051 running at a quiet 74 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The industry-leading 8 gallon fuel capacity provides a whopping 12 hours of run time. Starting is as simple as the push of a button on the H08051. All of our Hybrid Series Generators run on gasoline or propane fuel, giving you flexibility while out on the road or during an emergency. H08051 comes standard with extended propane hose (5.5ft) for convenience when running off a larger propane tank. The FIRMAN Volt Lock automatic voltage regulator ensures clean, consistent power output from the FIRMAN Power Stream alternator. For the ultimate in portability the H08051 includes a wheel kit featuring 10” never-flat wheels and a u-shaped padded handle with ergonomic grip. Pertinent information is at your fingertips with our 3-in-1 data minder measuring Volts, Hertz, Hours and a low oil indicator. The durable, compact tubular roll cage frame design is built for years of use. Everything you need comes standard in the box including: oil, funnel, owner’s manual, spark plug wrench, and two wrenches to remove protective shipping brackets.
