2. Safety Information

Operating a generator can be hazardous if proper safety precautions are not followed. Always prioritize safety to prevent injury or property damage.

2.1 Carbon Monoxide Hazard

• Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas.
• NEVER operate the generator indoors, in a garage, or in any enclosed space.
• Always operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents.
• Install battery-operated carbon monoxide alarms in your home or RV.

2.2 Electrical Safety

• Do not operate the generator in wet conditions. Keep it dry.
• Ensure all electrical connections are secure and free from damage.
• Use only approved extension cords that are rated for outdoor use and the power requirements of your appliances.
• Never overload the generator. Refer to the wattage ratings.

2.3 Fuel Safety

• Gasoline is highly flammable. Store fuel in approved containers in a well-ventilated area.
• Never refuel the generator while it is running or hot. Allow it to cool down completely.
• Avoid spilling fuel. If spilled, wipe it up immediately and ensure fumes dissipate before starting the generator.

2.4 Hot Surfaces

• The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown.
• Avoid touching hot surfaces to prevent burns.
• Keep children and pets away from the operating generator.

4. Setup

Before first use, the generator requires some initial setup steps.

4.1 Unpacking

• Carefully remove the generator from its packaging.
• Inspect for any shipping damage. Contact customer support if damage is found.
• Ensure all included components, such as the wrench, are present.

4.2 Adding Engine Oil

The generator is shipped without engine oil. It is crucial to add the correct type and amount of oil before starting.

• Place the generator on a level surface.
• Locate the oil fill cap/dipstick.
• Using a funnel, slowly add 10W-30 4-stroke engine oil until it reaches the upper mark on the dipstick. Do not overfill.
• Securely replace the oil fill cap/dipstick.

4.3 Adding Fuel

Use fresh, unleaded gasoline with an octane rating of 87 or higher.

• Ensure the generator is turned OFF and has cooled down.
• Open the fuel tank cap.
• Carefully pour gasoline into the fuel tank, avoiding overfilling. Leave some space for fuel expansion.
• Securely close the fuel tank cap.

5. Operating Instructions

Follow these steps for safe and effective operation of your generator.

5.1 Starting the Generator

1. Ensure the generator is on a level surface and in a well-ventilated outdoor area.
2. Check oil and fuel levels.
3. Turn the engine switch to the 'ON' position.
4. Move the choke lever to the 'CHOKE' position (if the engine is cold).
5. Pull the recoil starter handle firmly and smoothly until the engine starts.
6. Once the engine starts, slowly move the choke lever to the 'RUN' position.

5.2 Connecting Electrical Devices

• Allow the generator to run for a few minutes to stabilize.
• Plug in your appliances to the appropriate AC or DC outlets.
• Do not exceed the generator's running wattage (3600W) or the individual outlet's rating.

5.3 ECO Mode Operation

• The ECO mode switch, located on the control panel, allows the engine speed to automatically adjust to the load.
• Turn ECO mode 'ON' for improved fuel efficiency and quieter operation when running lighter loads.
• Turn ECO mode 'OFF' when connecting high-demand appliances or when stable power is critical.

5.4 Parallel Operation

To connect two PowerSmart inverter generators for increased power output:

• Ensure both generators are turned OFF and cooled.
• Connect the parallel kit (sold separately) according to its instructions.
• Start both generators as described in Section 5.1.
• Once both are running stably, you can connect higher wattage appliances to the parallel outlets.

5.5 Stopping the Generator

1. Disconnect all electrical loads from the generator.
2. Allow the generator to run for a few minutes without load to cool down.
3. Turn the engine switch to the 'OFF' position.
4. Turn the fuel valve to the 'OFF' position (if applicable).

6. Maintenance

Regular maintenance is essential for the safe and efficient operation of your generator.

6.1 Maintenance Schedule

6.2 Engine Oil Change

• Run the engine for a few minutes to warm the oil, then shut it off.
• Place a drain pan under the oil drain plug.
• Remove the oil drain plug and oil fill cap/dipstick to allow oil to drain completely.
• Replace the drain plug and refill with the recommended amount of 10W-30 4-stroke engine oil.

6.3 Air Filter Maintenance

• Remove the air filter cover and element.
• Clean the foam element with warm, soapy water, rinse thoroughly, and allow to air dry.
• Lightly oil the foam element with engine oil and squeeze out excess.
• Reinstall the air filter element and cover.

7. Troubleshooting

This section addresses common issues you might encounter with your generator.

7.1 Engine Will Not Start

• No Fuel: Check fuel level and add fresh gasoline if necessary.
• No Oil: Check engine oil level. The low oil shutdown system will prevent starting if oil is insufficient.
• Choke Position: Ensure the choke is in the correct position for starting (CHOKE for cold engine, RUN for warm engine).
• Engine Switch: Verify the engine switch is in the 'ON' position.
• Spark Plug: Inspect the spark plug for fouling or damage. Clean or replace if needed.

7.2 No Power Output

• Overload: If the overload indicator is lit, disconnect appliances and press the overload reset button. Reduce the load before reconnecting.
• Circuit Breaker: Check if any AC circuit breakers have tripped. Reset them if necessary.
• ECO Mode: Ensure ECO mode is off if running high-demand appliances.

7.3 Engine Runs Poorly

• Stale Fuel: Drain old fuel and refill with fresh gasoline.
