2. Safety Information

Operating a portable generator involves potential hazards. Adhere to all safety warnings and instructions to prevent injury or property damage.

• Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas. Operate the generator outdoors only, far away from windows, doors, and vents. Never operate in an enclosed space. The integrated COsense® technology is designed to detect dangerous levels of carbon monoxide and automatically shut down the generator, but it is not a substitute for safe operation.
• Fire Hazard: Fuel is highly flammable. Store fuel in approved containers in a well-ventilated area. Do not refuel a hot or running engine. Ensure proper ventilation and clearance around the generator during operation.
• Electrical Shock Hazard: Never operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded. Do not connect the generator directly to your home's electrical system without a transfer switch installed by a qualified electrician.
• Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact with hot surfaces to prevent burns.
• Moving Parts: Keep hands, feet, hair, and clothing away from moving parts to prevent entanglement.

5. Setup

Before first use, perform the following setup steps:

1. Assemble Handle and Wheels: Attach the handle and wheel kit to the generator frame as per the instructions provided with the kit. This enhances portability.
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 pour the provided engine oil into the oil fill opening until the oil level reaches the upper mark on the dipstick. Do not overfill. Securely replace the oil fill cap/dipstick.
3. Connect Battery: Connect the positive (+) battery cable (red) to the positive (+) battery terminal, then connect the negative (-) battery cable (black) to the negative (-) battery terminal. Ensure connections are tight.
4. Choose Fuel Type: Decide which fuel source you will use (gasoline, liquid propane, or natural gas).
5. Add Fuel (Gasoline): If using gasoline, ensure the generator is off and cool. Fill the fuel tank with fresh, unleaded gasoline (minimum 87 octane) up to the fill neck, but do not overfill. Securely close the fuel cap.
6. Connect Fuel (Propane/Natural Gas): If using liquid propane, connect the LP hose with regulator to the generator's LP inlet and to a propane tank. Ensure all connections are tight. If using natural gas, connect the natural gas line to the generator's natural gas inlet. Consult a qualified professional for natural gas connections.

6. Operating Instructions

Always operate the generator outdoors in a well-ventilated area, away from any structures, and on a level surface.

Starting the Generator (Electric Start)

1. Ensure Safety: Verify all electrical loads are disconnected from the generator.
2. Select Fuel: Turn the fuel selector dial to the desired fuel type (Gasoline, LP, or NG).
3. Open Fuel Valve: Open the fuel valve for the selected fuel source. For LP, open the valve on the propane tank. For NG, ensure the natural gas supply is open.
4. Choke (if applicable): If starting a cold engine, move the choke lever to the 'CHOKE' position.
5. Start Engine: Turn the Off/Run/Start switch to the 'START' position and hold until the engine starts. Once started, release the switch to the 'RUN' position.
6. Choke (if applicable): Gradually move the choke lever to the 'RUN' position as the engine warms up.
7. Connect Loads: Once the engine is running smoothly, you can connect your electrical devices.

Stopping the Generator

1. Disconnect Loads: Disconnect all electrical loads from the generator.
2. Turn Off Fuel: For LP, close the valve on the propane tank. For gasoline, turn the fuel valve to the 'OFF' position. Allow the generator to run until it runs out of fuel (this helps prevent carburetor issues). For NG, turn off the natural gas supply.
3. Turn Off Engine: Once the engine stops or after the fuel has been shut off, turn the Off/Run/Start switch to the 'OFF' position.

Runtime Information

Approximate runtimes at 50% load:

• Gasoline Powered: Up to 9.5 hours
• Propane Powered: Up to 4.5 hours
• Natural Gas Powered: Runtime varies based on home gas line pressure and demand.

7. Maintenance

Regular maintenance ensures optimal performance and longevity of your generator. Refer to the full owner's manual for a detailed maintenance schedule.

• Check Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 50-100 hours or annually.
• Clean Air Filter: Inspect the air filter regularly and clean or replace as needed, especially in dusty conditions.
• Inspect Spark Plug: Check the spark plug annually or every 100 hours. Clean or replace if fouled or worn. Ensure proper gap (.030 inches).
• Inspect Fuel System: Regularly check fuel lines and connections for leaks or damage.
• Clean Generator: Keep the generator clean and free of debris. Ensure cooling fins are clear for proper airflow.
• Battery Maintenance: Keep the battery charged and terminals clean.
