Step 2- Add Gasoline
WARNING:
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.
• Do not smoke near 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. Clean up any spilled fuel before
starting.
• Empty fuel tank before storing or transporting the generator.
• Before transporting, turn fuel valve to off position and disconnect spark plug wire.
Use fresh (within 30 days from purchase), unleaded gasoline with a minimum 87 octane rating. Do
not use gasoline which contains Methanol. Do not mix oil with gasoline.
To add gasoline, follow these steps:
1. Make sure the generator is on a level surface.
2. Unscrew fuel cap (NOTE: the fuel cap may be tight and hard to unscrew).
3. Slowly add unleaded gasoline to the fuel tank. Be careful not to overfill. Please refer to the
chart in figure 3 for the fuel capacity. The fuel gauge on the top of the generator indicates
how much gasoline is in the generator fuel tank. NOTE: Do not fill the fuel tank to the
very top. Gasoline will expand and spill over during use even with the fuel cap in place.
4. Reinstall fuel cap and wipe off any spilled gasoline with a dry cloth.
IMPORTANT:
• Never use an oil/gasoline mixture.
• Never use old gasoline.
• Avoid letting dirt or water into the fuel tank.
• Gasoline can age in the tank and make it hard to start up the generator in the future. Never
store generator for extended periods of time with fuel in the tank.
