2. Safety Information

Operating a generator safely is crucial. Failure to follow these instructions can result in serious injury or death.

• Carbon Monoxide (CO) Hazard: Generators produce carbon monoxide, an odorless, colorless, and poisonous gas. Operate the generator outdoors only and far away from windows, doors, and vents. The generator is equipped with a CO Protect system designed to shut down the engine if dangerous levels of carbon monoxide are detected.
• 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.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure the generator is properly grounded. Never connect the generator directly to a building's electrical system without a transfer switch installed by a qualified electrician.
• Hot Surfaces: The 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 at all times.

4. Setup

Before first use, perform the following setup steps:

1. Unpacking: Remove the generator and all accessories from the packaging. Inspect for any damage.
2. Add Engine Oil: The generator is shipped without engine oil. Place the generator on a level surface. Remove the oil fill cap/dipstick. Slowly add 0.37 quarts (0.35 liters) of 10W-30 engine oil. Do not overfill. Reinstall the oil fill cap/dipstick.
3. Add Fuel: Ensure the generator is off and cool. Remove the fuel cap. Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane). Do not overfill. Securely replace the fuel cap.
4. Grounding: For safety, connect a ground wire from the generator's ground terminal to an appropriate ground source (e.g., a ground rod).

5. Operating Instructions

5.1 Starting the Generator

1. Ensure the generator is on a level, outdoor surface, away from combustible materials.
2. Turn the fuel valve to the 'ON' position.
3. If the engine is cold, move the choke lever to the 'CHOKE' position. If the engine is warm, move it to the 'RUN' position.

5. Once the engine starts, slowly move the choke lever to the 'RUN' position.

5.2 Connecting Electrical Loads

1. Allow the engine to run for a few minutes to warm up.
2. Plug in your electrical devices to the appropriate AC or DC outlets. Ensure the total wattage does not exceed the generator's running wattage (1900W).
3. For optimal fuel efficiency and reduced noise, switch the ECO mode to 'ON'. The engine speed will adjust automatically based on the load.

5.3 Parallel Operation

To increase power output, two identical PowerSmart 2500-Watt Inverter Generators can be connected using a parallel kit (sold separately).

1. Ensure both generators are off and cool.
2. Connect the parallel kit cables to the designated parallel ports on both generators.
3. Start both generators according to the standard starting procedure.
4. Once both generators are running, you can connect your electrical loads to the outlets on the parallel kit.

5.4 Stopping the Generator

1. Disconnect all electrical loads from the generator.
2. Turn the engine switch to the 'OFF' position.
3. Turn the fuel valve to the 'OFF' position.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your generator.

• Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 50-100 hours or annually.

• Air Filter: Inspect and clean the air filter every 50 hours or more frequently in dusty conditions. Replace if damaged.
• Spark Plug: Inspect the spark plug every 100 hours. Clean or replace as needed.
• 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; avoid spraying water directly on electrical components.
