• Fire Hazard: Propane is highly flammable. Do not smoke or use open flames near the generator or propane tank. Ensure all connections are secure and free of leaks.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are dry and properly grounded.
• 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.

3. Setup

3.1 Initial Placement and Safety Distance

Before operating, ensure the generator is placed on a firm, level surface outdoors. It must be at least 20 feet away from any windows, vents, or doors of your home or any other building to prevent carbon monoxide fumes from entering. Ensure adequate ventilation around the unit.

3.2 Checking Engine Oil Level

It is good practice to check the engine's oil level before each startup. The oil dipstick is located on the side of the engine.

1. Unscrew the green knob (oil dipstick) located on the side of the engine.
2. Wipe the dipstick dry with a clean cloth.
3. Without threading it in, insert the dipstick back into the oil port.
4. Pull the dipstick out and check the oil level. It should be between the high and low markings.
5. If the oil level is low, use the included oil funnel to add more oil (refer to specifications for oil type and capacity).
6. Once the oil level is correct, reinstall the dipstick and tighten the cap.

3.3 Propane Tank Inspection

Before connecting the propane tank, inspect it for leaks. This is a critical safety step.

1. Prepare a soapy mixture in a spray bottle (e.g., dish soap and water).
2. Spray the entire propane tank, especially around the valve and seams.
3. Watch for any bubbles to appear on the surface. Bubbles indicate a leak.
4. If you observe any leaks, do NOT use the tank. Replace it immediately.

3.4 Attaching the Propane Tank

The generator is designed with an onboard storage area for a 20 LB propane tank.

1. Lower the gate on the back of the generator's propane tank holder.
2. Carefully place the propane tank into the designated space.
3. Secure the propane tank using the elastic strap provided. Hook one side of the strap, pull it tightly around the tank, and hook the other side.
4. With the propane tank valve closed, attach the regulator valve of the 5-ft propane hose to the tank. Ensure this connection is hand-tight and secure.
5. Attach the other end of the propane hose to the generator's inlet. Tighten this connection securely with a wrench.
6. Slowly open the valve on your propane tank all the way to allow gas flow to the generator.

3.5 Installing the 24V iON+ Battery

The 24V iON+ battery powers the electric start feature (PowerSTART).

1. Open the top compartment on the generator's control panel.
2. Insert the fully charged 24V 2.0-Ah iON+ battery into the battery slot until it clicks into place.
3. Close the compartment cover.

4. Operating Instructions

It is recommended to fully test your generator when you first receive it. Set it up, turn it on, and run it for about 5 minutes to ensure everything is working perfectly before storing it away.

4.1 Electric Start (PowerSTART)

1. Ensure the propane tank is connected and its valve is fully open.
2. Locate the choke lever on the engine. Move the choke lever from the "Run" side to the "Start" side (typically to the left).
3. On the control panel, press and hold the "Start" button until the engine turns on.
4. Once the engine starts, immediately push the choke lever back to the "Run" side.

Figure 4.1: Push-Button Start. This image shows a hand pressing the green "Start" button on the generator's control panel, indicating the electric start option.

4.2 Manual Start (Recoil)

In case the electric start is not available or preferred, you can use the recoil start.

1. Ensure the propane tank is connected and its valve is fully open.
2. Move the choke lever to the "Start" position.
3. Set the main power switch on the control panel to the middle "ON" position.
4. Firmly grasp the recoil pull cord handle. Give the pull cord a swift, strong pull until the engine starts.
5. Once the engine starts, immediately push the choke lever back to the "Run" side.

4.3 Stopping the Generator

To turn off the generator, simply push the main power switch on the control panel to the "OFF" position.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your generator.

• Oil Changes: Refer to the full user manual for recommended oil change intervals. Regularly check oil levels as described in Section 3.2.
• Air Filter: Periodically inspect and clean the air filter to ensure proper engine function and prevent dirt/dust from entering.
• Spark Plug: Inspect and clean or replace the spark plug as needed.
• General Cleaning: Keep the generator clean and free of debris. Use a damp cloth to wipe down surfaces.

6. Storage

Proper storage is essential to protect your generator when not in use.

1. After use, allow the generator to cool down for approximately 20 to 30 minutes.
2. Close the valve on the propane tank.
3. Detach the propane hose from both the tank and the generator.
4. Remove the 24V iON+ battery from its compartment. Store the battery and charger in a cool, dry place.
5. To make the generator more compact for storage, pull the pin on the handle and fold it down.
6. Cover the generator with the provided cover to protect it from dust and elements.
7. Store the generator in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.

7. Troubleshooting

This section provides general guidance for common issues. For detailed troubleshooting, please refer to the comprehensive user manual.

• Engine Not Starting:
  • Check propane tank: Ensure it's full and valve is fully open.
  • Check oil level: Low oil will prevent starting due to the low-oil sensor.
  • Check battery: Ensure 24V iON+ battery is charged and properly installed for electric start.
  • Choke position: Verify choke is in "Start" position for initial ignition, then moved to "Run".
• No Power Output:
  • Check circuit breakers: Ensure they are not tripped. Reset if necessary.
  • Overload: Reduce the load on the generator.
