EQUIPMENT DESCRIPTION & KNOWING YOUR GENERATOR Please read this manual and follow the procedures covered in this manual. Become familiar with the generators functions, applications, and limitations. Below is a diagram of the locations of the various controls and functions of the generator. WARNING: DO NOT exceed the generator’s wattage / amperage capacity.
ELECTRIC SHOCK AND SHORT CIRCUIT Be sure to notify the utility company when using the generator for backup power. Use approved transfer equipment to isolate the generator from electric utility. In highly conductive area such as metal decking or steel work, use a ground circuit fault interrupter. Never touch the generator if the generator is wet. Also, never touch the generator if your hand is wet.
BATTERY (optional: for electric start units only) The battery is free maintenance, but also need to charge. Batteries contain electrolyte fluid or battery acid. Batteries emit hydrogen gases as battery is being charged. The slightest spark will ignite hydrogen and cause and explosion. ENGINE SAFETY PRECAUTIONS Do not touch hot surfaces.
ENGINE OIL • Fill the engine with SAE 10W-30 engine oil for general use or follow the table below. • Make sure the generator is on a level surface and make sure the oil dipstick is on tight. GASOLINE •Add unleaded gasoline and never fill the fuel tank indoors. Also, be sure to install the fuel tank cap on tight after filling.
•DO NOT overfill the fuel tank. Always allow room for fuel expansion. • Never fill the fuel tank when the engine is running or hot. Allow the unit to cool for two minutes before refueling. DO NOT light a cigarette or smoke when filling the fuel tank. AIR CLEANER •...
Using a No. 12 AWG (American Wire Gauge) stranded copper wire to the frame and to an earth-driven copper or brass grounding rod provides sufficient safety against shock. However, local codes may differ. Contact a local electrician to find out specifications for grounding your generator. Note: Grounding your generator is highly recommended.

CAUTION! turned ON. (AEG8000XE) (AEG4000X) • Pull the recoil starter grip lightly until resistance is felt, then pull hard. Warning: DO NOT allow the starter grip to snap back against the engine. Return it gently (Figure 5.). Gradually push the choke rod to the “OPEN” position as the engine warms up (Figure 6).
CONNECTING ELECTRICAL LOADS AND ELECTRICAL CAPACITY After the generator has started, let the engine warm up before connecting any electrical loads to it. Do not have any electrical loads connected before starting the generator. Do not connect 240 Volt loads to the 120 Volt sockets. Do not connect 120 Volt loads to the 240 Volt sockets.

• Let the engine run at no-load for several minutes to stabilize the internal temperatures of engine and generator. • Turn the engine switch to the “OFF” position (Figure 3.). (AEG8000XE) (AEG4000X) • Turn the fuel valve to the “OFF” position (Figure 4.).
RECEPTACLES This generator is equipped with the following receptacles: 120 Volt AC, 20 Amp Duplex Receptacles Figure 5. 110 Volt, 20 Amp Duplex Receptacles Figure 6. 220 Volt, NEMA L14-20 Note: Please be sure to use electrical cords that support the amount of wattage being used. The electrical cords should be able to handle 20 Amps of current at 125 Volts.
Note: ⑴ These items should be serviced by a dealer. ⑵ Every 3 years. CLEANING THE GENERATOR Generator maintenance consists of keeping the unit clean and dry. Be sure to store the unit in a clean and...
dry environment, where it will not be exposed to excessive dust, dirt, moisture or any corrosive vapors. Cooling slots should always be clean and free from clogs. Note: Do not use a garden hose to clean the generator. Water can enter the fuel and intake system and cause problems.
