STEP 2 - ADD / CHECK FUEL
WARNING! RISK OF EXPLOSION. HIGHLY FLAMMABLE: This generator may emit highly flammable and
explosive gasoline vapors, which can cause severe burns or even death, if ignited. A nearby open flame can lead
to explosion even if not directly in contact with gasoline.
• Do not operate near open flame, heat, or any other ignition source. Do not smoke near the generator.
• Always operate on a firm, level surface.
• Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before removing
fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow for
expansion. Always check for spilled fuel before operating.
• If fuel spills, move the generator at least 30 feet away from the spill and wipe clean any spilled fuel before
starting the engine.
• Empty fuel tank before storing or transporting the generator.
Use ONLY fresh (within 30 days from purchase), lead-free gasoline with a minimum of 87 octane rating. The genera-
tor performs best with ethanol-free gasoline. DO NOT use gasoline with over 10% ethanol. The capacity of the fuel
tank is 6 US gallons (23 L). Do not mix oil with gasoline.
To add gasoline:
1. Place the generator on a level surface. Make sure the en-
gine is OFF before adding or checking the fuel.
2. Unscrew the fuel cap (Fig. 8 - 1) and set it aside. The fuel
cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be careful
not to overfill. Reinstall fuel cap and wipe clean any spilled
gasoline with a dry cloth.
NOTE: Do not fill the fuel tank to the very top. If you do so,
gasoline will expand and spill during use, even with the fuel
cap in place.
4. Reinstall fuel cap and wipe clean any spilled gasoline with
a dry cloth.
To check fuel level:
1. Before starting the generator, check the fuel gauge to see
if there is sufficient fuel inside the tank:
• E = Empty
• F = Full
2. If the tank is empty add gasoline to the gas tank. See
above section, "To Add Gasoline".
GENERATOR PREPARATION
IMPORTANT:
• Avoid getting dirt or water into the fuel tank.
• Keep gasoline away from sparks, open flames,
pilot lights, heat, and other sources of ignition.
• Gasoline can age in the tank and make starting
difficult. Never store the generator for more
than 2 months with fuel in the tank.
• Never use an oil/gasoline mixture.
• Never use old gasoline.
