Safety Information
WARNING: Read and understand all safety warnings and instructions before operating this generator. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.
- Carbon Monoxide Hazard: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operating a generator indoors can kill you in minutes. ALWAYS operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents.
- CO Shutdown System: This generator is equipped with a carbon monoxide (CO) detection system that automatically shuts down the engine if CO levels become dangerously high. If the generator shuts down due to CO, move it to an open-air location and allow it to ventilate before attempting to restart. Do not disable this safety feature.
- Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure all electrical connections are dry and properly grounded.
- Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke while refueling.
- Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for a period after shutdown. Avoid contact to prevent burns.
- Children and Pets: Keep children and pets away from the generator during operation.
Product Features
- Quiet Power: Low 52dB output, suitable for camping, tailgating, and emergency backup.
- Maximum Efficiency: 80cc engine with Engine Smart Control and variable throttle automatically adjusts engine RPM based on power needs for quieter operation and reduced fuel consumption.
- Safe Operation: Carbon monoxide detection provides additional safety and peace of mind.
- Clean Electricity: Produces less than 3% total harmonic distortion (THD) for safely operating sensitive electronics.
- Durable Construction: 100% copper-wound generator head prevents overheating for longer life.
- Forest Service Qualified: U.S.D.A. Forest Service-Qualified Spark Arrester allows for safe use in parks and forests.

Setup
- Unpacking: Carefully remove the generator from its packaging. Inspect for any shipping damage. Ensure all components listed in the packing list are present.
- Placement: Place the generator on a firm, level surface outdoors, in a well-ventilated area. Ensure there is at least 5 feet (1.5 meters) of clear space around the generator to allow for proper airflow and exhaust dispersion. Never operate indoors or in partially enclosed spaces.
- Add Engine Oil:
- Remove the oil fill cap/dipstick.
- Add the recommended engine oil (typically SAE 10W-30 for general use) to the crankcase until it reaches the upper mark on the dipstick. Do not overfill. The oil capacity is not specified in the provided data, refer to the generator's specific oil capacity label or included quick start guide.
- Securely replace the oil fill cap/dipstick.
- Add Fuel:
- Ensure the generator is off and cool.
- Unscrew the fuel cap.
- Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not overfill; leave space for fuel expansion. The tank volume is 1.18 gallons.
- Securely replace the fuel cap. Wipe up any spilled fuel immediately.
- Grounding: For safety, the generator must be properly grounded. Connect a grounding wire from the generator's grounding terminal to an appropriate ground source, such as a ground rod.
Operating Instructions

- Pre-Start Check:
- Check engine oil level.
- Check fuel level.
- Ensure all electrical devices are disconnected from the generator.
- Verify the generator is on a level surface in a well-ventilated outdoor area.
- Starting the Engine (Recoil Start):
- Turn the fuel valve to the 'ON' position.
- Set the engine switch to 'ON'.
- If the engine is cold, move the choke lever to the 'CHOKE' position.
- Firmly pull the recoil starter handle until the engine starts.
- Once the engine starts, slowly move the choke lever to the 'RUN' position.
- Connecting Electrical Devices:
- Allow the engine to run for a few minutes to warm up.
- Plug in your electrical devices. Do not exceed the generator's rated wattage (1800 running watts, 2500 starting watts).
- Ensure the total load does not exceed the capacity of the individual outlets.
- Using Economy Mode:
- The Economy Mode switch (often labeled 'ECO' or 'Smart Throttle') reduces engine speed when the electrical load is low, improving fuel efficiency and reducing noise.
- Flip the switch to 'ON' for economy mode. For full power or when starting high-load devices, set it to 'OFF'.
- CO Shutdown System: If the generator detects high levels of carbon monoxide, it will automatically shut down. If this occurs, immediately move the generator to an area with fresh air and allow it to ventilate before attempting to restart. Do not operate the generator in the same location where a CO shutdown occurred until the area is thoroughly ventilated.
- Stopping the Engine:
- Disconnect all electrical loads.
- Allow the generator to run for a few minutes without load to cool down.
- Turn the engine switch to 'OFF'.
- Turn the fuel valve to the 'OFF' position.
Maintenance
Regular maintenance is crucial for the longevity and reliable operation of your generator. Perform checks and service at the recommended intervals.
