2. Safety Information
WARNING: Carbon Monoxide Hazard.
Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide (CO), a poisonous gas you cannot see or smell. NEVER use in an enclosed area or partially enclosed area. Always use OUTDOORS and far away from windows, doors, and vents.
WARNING: Electrical Shock Hazard.
Do not operate in wet conditions. Ensure all connections are dry and secure. Ground the generator properly to prevent electrical shock.
WARNING: Fire Hazard.
Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator. Store fuel in approved containers only.
WARNING: Hot Surfaces.
The generator engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
Always read and understand the complete safety instructions in the full owner's manual before operating this equipment.

- Status Indicator Lights: Indicate output, overload, and low oil conditions.
- Hour Meter: Tracks engine run time for maintenance scheduling.
- USB Outlets (2x 2.4A 5VDC): For charging small electronic devices.
- AC Outlets: 1x Duplex 5-20R 20A 120VAC and 1x L5-30R 30A 120VAC Twist Lock (RV Ready).
- Parallel Connectivity Port: Allows connection of two compatible generators for increased power.
4. Setup
Follow these steps for initial setup before operating your generator:
- Unpacking: Carefully remove the generator from its packaging. Inspect for any damage. Ensure all included accessories (oil funnel, spark plug wrench, etc.) are present.
- Add Engine Oil: The engine is shipped without oil. Place the generator on a level surface. Remove the oil fill cap/dipstick. Using the provided funnel, slowly add 10W-30 engine oil until it reaches the upper mark on the dipstick. Do not overfill. (Capacity: approximately 0.6 quarts).
- Add Fuel: Ensure the generator is off and cool. Open the fuel tank cap. Slowly add fresh, unleaded gasoline (minimum 87 octane) to the fuel tank. Do not fill above the red indicator ring inside the tank. Securely close the fuel cap. (Tank Volume: 2.6 Gallons).
- Grounding: Connect a grounding wire from the generator's grounding terminal to a suitable ground source, as per local electrical codes.

5. Operating Instructions
Follow these steps to safely start and operate your generator:
- Preparation: Ensure the generator is on a level, outdoor surface, away from combustible materials and at least 20 feet from any building openings. Check oil and fuel levels.
- Starting Procedure:
- Turn the fuel valve to the 'ON' position.
- Turn the engine switch to the 'ON' position.
- Pull the choke lever to the 'CHOKE' position (if the engine is cold).
- Firmly pull the recoil starter handle until the engine starts. Allow the engine to run for a few seconds.
- Slowly push the choke lever to the 'RUN' position.
- Connecting Electrical Devices: Once the engine is running smoothly and the green 'Output Indicator' light is on, you can connect your electrical devices to the appropriate outlets. Do not exceed the generator's running wattage (3200W).
- Eco-Mode Operation: For lighter loads, activate the 'Eco-Mode' switch. This reduces engine speed, saving fuel and lowering noise levels. The engine will automatically adjust speed based on load demand.
- Parallel Operation: This generator is equipped with a parallel connectivity port. Refer to the full manual for instructions on connecting two compatible A-iPower inverter generators for increased power output.
- Shutting Down:
- Disconnect all electrical devices.
- Turn the engine switch to the 'OFF' position.
- Turn the fuel valve to the 'OFF' position.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your generator. Always perform maintenance with the engine off and cool.
- Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 100 hours or annually, whichever comes first.
- Air Filter: Inspect every 50 hours or monthly. Clean or replace if dirty.
- Spark Plug: Inspect and clean every 100 hours or annually. Replace if worn or damaged.
- Fuel System: For long-term storage (over 30 days), drain the fuel tank and carburetor, or use a fuel stabilizer to prevent fuel degradation.
- Cleaning: Keep the generator clean and free of debris. Use a damp cloth to wipe down exterior surfaces.
Refer to the complete maintenance schedule in the full owner's manual for detailed instructions and additional maintenance tasks.
