OPERATION
NOTICE Do not mix oil in gasoline or modify engine to run on alternate fuels not described in this
manua I. Use of unapproved fuels could damage engine and will not be covered underwarranty.
1. Clean area around fuel fill cap, remove cap.
2. Slowly add unleaded fuel to fuel tank. Be careful not to fill above the RED fuel level indicator.
This allows adequate space for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate before starting engine.
Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a minimum 85 octane gasoline is acceptable.
Engine power and generator output will be reduced approximately 3.5% for every 1000 feet (305 m)
of elevation above sea level. High altitude may cause hard starting, increased fuel consumption
and sparkplug fouling. To operate at high altitudes FIRMAN can provide a high altitude carburetor
main jet. The alternative main jet and installation instructions can be obtained by contacting
Customer Support.

NOTICE Operation using an alternative main jet at elevations lower than the recommended
minimum altitude can damage the engine. For operation at lower elevations, the standard main
jet supplied must be used. Operating the engine with the wrong main jet may increase exhaust
emissions, fuel consumption and reduce performance.
Operation at High Ambient conditions
Your Firman Power Equipment product is designed and rated for continuous operation at ambient
temperatures up to 104°F (40°C). The generator may be operated at temperatures ranging from
5°F(-15°C) to 122°F(50°C) for short periods. If the generator is exposed to temperatures outside
this range during storage, the generator should be brought back within this range before
operation. When operated above 77°F(25°C) there may be a decrease in power.
Maximum wattage and current are subject to and limited by such factors as ambient temperature,
altitude, engine conditions etc.
