2. Safety Information
WARNING: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Using a generator indoors CAN KILL YOU IN MINUTES. Always use generators outdoors and far away from windows, doors, and vents.
- Carbon Monoxide Hazard: Never operate the generator inside any building, garage, shed, or other enclosed space. Ensure adequate ventilation when operating outdoors.
- Fire Hazard: Gasoline and propane are highly flammable. Refuel only when the engine is off and cool. Do not smoke near the generator. Store fuel in approved containers in a well-ventilated area.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and dry. Never connect the generator directly to a building'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 to prevent burns.
- Hearing Protection: Wear appropriate hearing protection when operating the generator for extended periods.
- Children and Pets: Keep children and pets away from the generator at all times.

4. Setup
Before initial use, perform the following setup steps:
- Unpacking: Carefully remove the generator from its packaging. Inspect for any shipping damage.
- 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 the recommended oil (refer to specifications for type and capacity) until it reaches the upper mark on the dipstick. Do not overfill. Securely replace the cap.
- Add Fuel (Gasoline): Ensure the generator is off and cool. Open the fuel cap and carefully pour fresh, unleaded gasoline into the fuel tank. Do not fill above the red indicator ring inside the tank. Securely close the fuel cap.
- Connect Propane (LPG): If using propane, connect the propane regulator and hose (included) to a standard 20-lb. propane tank and to the generator's LPG inlet. Ensure all connections are tight.
- Battery Connection: Connect the battery cables to the generator's battery terminals. Ensure correct polarity (red to positive, black to negative).
- Wheel and Handle Assembly: Attach the wheels and extendable handle as per the assembly instructions provided in the separate assembly guide.
5. Operating Instructions
5.1 Starting the Generator
Ensure the generator is on a level, outdoor surface, away from any enclosed areas, and at least 15 feet from any windows or doors.
Figure 5.1: Dual Fuel Selector.
Figure 5.2: Engine Start/Stop Button.
- Select Fuel Type: Turn the fuel selector switch to either "GAS" for gasoline or "LPG" for propane.
- Turn on Battery Switch: Locate the battery switch on the control panel and turn it to the "ON" position.
- Start Engine:
- Electric Start: Press and hold the "ENGINE START/STOP" button for a few seconds until the engine starts.
- Remote Start: Use the provided wireless remote control to start the generator.
- Recoil Start: If the battery is low or for manual starting, pull the recoil starter handle firmly and smoothly until the engine starts.
- Connect Loads: Once the engine is running smoothly, you can connect your electrical devices to the appropriate outlets. Do not overload the generator.
5.2 Stopping the Generator
- Disconnect Loads: Unplug all electrical devices from the generator outlets.
- Stop Engine: Press the "ENGINE START/STOP" button or use the remote control to shut down the generator.
- Turn off Battery Switch: Turn the battery switch to the "OFF" position.
- Close Fuel Valve: If using propane, close the valve on the propane tank. If using gasoline, turn the fuel selector to the "OFF" position to run the carburetor dry for storage.
6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your generator. Always perform maintenance when the engine is off and cool.
6.1 Maintenance Schedule
| Item | Every Use | Every 25 Hours / Monthly | Every 100 Hours / Annually |
