Notice Regarding Emissions:
Engines certified to comply with California and U.S. EPA emission regulations for SORE (Small Off Road Equipment) are certified to operate on
regular unleaded gasoline and may include the following emission control systems: Three-Way Catalyst (TWC) (if equipped), and Engine
Modifications (EM).
Legal Requirements:
Federal and/or State Occupational Safety and Health Administration (OSHA) regulations, local codes, and/or ordinances may apply to the intended
use of this generator. Consult a qualified electrician, electrical inspector, and/or the local agency having jurisdiction. Some areas require generators
to be registered with local utility companies. Additional regulations may apply if this generator will be used at a construction site.
IMPORTANT SAFETY INSTRUCTIONS
STOP!
Before using this generator and if you have any questions regarding the hazard and safety notices listed in this manual and/or on this
generator, call 1-866-460-9437, Monday - Friday, 8 AM - 4 PM Central Time.
Carbon Monoxide Gas: When in operation, the exhaust from this generator contains poisonous carbon
monoxide gas. Carbon monoxide gas is both odorless and colorless AND may be present even if you do not
see or smell gas. Breathing this poison gas can lead to headaches, dizziness, drowsiness, loss of
consciousness and eventually death.
• Use this generator ONLY outdoors in non-confined areas.
• Keep at least several feet of clearance on all sides to allow proper ventilation for this generator.
Chemicals: According to the State of California, the exhaust from this generator contains chemicals known to
cause cancer, birth defects, or other reproductive harm.
Flammable Gasoline: This generator may emit highly flammable and explosive gasoline vapors, which can
cause severe burns or even death. A nearby open flame can lead to an explosion even if not directly in contact
with gasoline.
• Do not operate this generator near open flame.
• Do not smoke near this generator.
• Always operate this generator on a firm, level surface.
Gasoline is highly flammable and explosive. Handling fuel can result in serious injury or burns.
• Always shut down this generator before refueling. Refuel in a well-ventilated area. Keep heat, sparks and flame away
while refueling and away from the location where gasoline is stored. Never refuel indoors where gasoline fumes may
reach flames and/or sparks.
• Allow this generator to cool for at least 2 minutes before removing the fuel tank cap. Loosen the cap slowly to relieve
pressure in the fuel tank. Avoid spilling fuel.
• Do not fill the fuel tank above the upper limit line. Gasoline may expand during operation. Do not fill to the top of the
tank.
• Always check for spilled gasoline and immediately wipe it up before starting this generator.
• Empty the fuel tank before storing or transporting this generator.
• Always handle fuel outdoors.
• Before transporting, turn the fuel valve to the "off" position and disconnect the spark plug.

Powerful Voltage: This generator produces powerful voltage, which can result in electrocution.
• ALWAYS ground this generator before using it. (See “Ground the Generator” section in this manual).
• Only electrical devices should be plugged into this generator, either directly or with an extension cord. NEVER
connect a building electrical system to this generator without a qualified electrician. Such connections must isolate
generator power from utility power and comply with local electrical laws and codes. Failure to comply can create a back
feed into utility lines creating an electrocution hazard, which may result in serious injury or death to utility workers.
Such a back feed may cause this generator to explode, burn and create fires when utility power is restored.
• Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal decking or steel work. GFCIs
are available in-line with some extension cords.
• Do not use this generator in wet conditions (rain, snow, active sprinkler system, wet hands, etc.). Always keep this
generator dry and operate it with dry hands.
• Do not touch bare wires or outlets (receptacles).
• Do not allow children or non-qualified persons to operate this generator.
High Temperatures: This generator produces heat when in operation. Temperatures near the exhaust can
exceed 150 Degrees Fahrenheit (65 Degrees Celsius).
• Do not touch hot surfaces. Observe all warning placards on this generator denoting hot surfaces.
• Allow this generator to cool for several minutes after use before touching the engine, muffler or other areas that are
hot during operation and before storing indoors.
• Hot exhaust may ignite some materials. Keep flammable materials away from this generator.
• Keep at least several feet of clearance on all sides of this generator during operation. Do not enclose this generator in
any structure.
Usage: Misuse of this generator can damage it or shorten its life.
• Use this generator only for its intended purpose.
• Operate this generator only on a dry, level surface.
• Allow this generator to run for several minutes before connecting any electrical devices.
• Promptly turn off any malfunctioning devices and disconnect them.
• Do not operate an excessive number of electrical devices in excess of the wattage capacity of this generator.
• Do not turn on electrical devices until after they are connected to this generator.
• Turn off all connected electrical devices before stopping this generator.

PREPARING THE GENERATOR FOR USE
Using this Generator for the First-Time
STOP!
The following section describes the required steps for preparing this generator for the first use. Failure to correctly perform these steps
can damage this generator and/or shorten its life. If still unsure about how to perform any of these steps after reading this section, call
1-866-460-9437 Monday - Friday, 8 AM - 4 PM Central Time for customer service.
If this generator is being used for the first time, the following few steps are required to prepare it for operation:
Step 1 - Add Oil
This generator requires engine oil to function. Engine oil is a major factor affecting engine performance and service life. When new from
the package, this generator contains no oil in the engine crankcase. The correct quantity of oil is equal to the oil capacity of the engine crankcase
and is 38 fluid oz (1.13 L) for this ACDelco Model AC-G0004 5500 Surge Watts / 5000 Running Watts Electric Start Portable Generator. Add the
correct quantity of oil before operating this generator for the first time. When replenishing oil for subsequent use of this generator, always determine
that this generator has the correct quantity of oil.
Model AC-G0004 Oil Capacity (Qt/fluid oz./L) 1.2 / 38 / 1.13
Model AC-G0004 Oil Type Recommended High Detergent Motor Oil, SAE10W-30
To add oil:
1. Confirm that this generator is on a level surface.
2. Unscrew the oil filler/dipstick cap from the engine as illustrated in Figure 1.
3. Using a funnel, add high detergent motor oil to fill the engine crankcase to the correct quantity as stated above. SAE10W-30 oil is recommended
for general, all-temperature use. When the engine crankcase is full, the oil level should reach the lower lip of the oil filling opening as illustrated in
Figure 2.
4. Replace the oil filler/dipstick cap.
