ADD FUEL
DANGER! NEVER fill fuel tank indoors. NEVER
fill fuel tank when engine is running or hot. DO
NOT light a cigarette or smoke when filling the
fuel tank.
Use regular UNLEADED gasoline with the generator
engine. Regular leaded gasoline may also be used if
UNLEADED is not available.
CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, fuel hose or tank during storage.
Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract mois-
ture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Drain the
gas tank, start the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next season.
See “Storage” Instructions on page 10 for additional
information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
• Clean area around fuel fill cap, remove cap.
• Add “UNLEADED” regular gasoline, slowly, to fuel
tank.
• Install fuel cap and wipe up any spilled gasoline.
OPERATING THE GENERATOR
CAUTION! Never start, or stop, the engine gen-
erator with electrical loads connected to the
receptacles with the connected devices turned
ON.
STARTING THE ENGINE
• Disconnect all electrical loads from the generator.
• Move engine CHOKE CONTROL LEVER to “RUN”
position.
• Move ON/OFF SWITCH to “ON” position.
• If engine is warm, close choke only part way or leave
it fully open. A warm engine needs less choking than
a cold engine.
• Grasp starter grip and pull slowly until you feel some
resistance. Let rope return slowly. Then pull cord out
with rapid full arm stroke. Let rope return slowly. Do
not let rope “snap back” against starter.
• If engine “hunts” or falters after starting, apply choke
until engine begins running smoothly. Then return the
choke to the open position. If engine continues to
hunt, you may need to have the carburetor adjusted.
See Engine Owner’s Manual.
