2. Safety Information

Always prioritize safety when operating the generator. Failure to follow safety instructions can result in serious injury or death.

• Carbon Monoxide (CO) Hazard: Generators produce carbon monoxide, a colorless, odorless, poisonous gas. Operate the generator outdoors only, far away from windows, doors, and vents. The LF4800iE is equipped with a CO-MINDER sensor for added safety, which will shut down the generator if CO levels become dangerous.
• Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke near the generator.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all connections are secure and dry.
• 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.
• Proper Ventilation: Ensure adequate airflow around the generator during operation to prevent overheating.
• Children and Pets: Keep children and pets away from the generator at all times.
• Read the Manual: Always read the complete owner's manual before initial use and for any operational or maintenance procedures.

3. Setup

Before starting your generator for the first time, proper setup is crucial. This includes adding engine oil and fuel, and connecting the battery.

3.1. Add Engine Oil

The generator does not come with engine oil pre-filled. You must add the correct type and amount of oil before first use.

1. Place the generator on a horizontal surface.
2. Unscrew the bolts on the side cover and remove the cover to access the engine oil dipstick.
3. Unscrew and remove the oil dipstick.
4. Using the provided funnel, add 0.5 liters of recommended engine oil (e.g., 10W-40).
5. Use the oil dipstick to check the oil level. The oil level should be between the upper and lower scales on the dipstick.
6. Screw the oil dipstick back in and reattach the side cover.

3.2. Add Fuel

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

1. First, unscrew the fuel cap.
2. Fill up the proper amount of fuel (up to 10 liters) using a funnel.
3. Observe the fuel indicator; the fuel level should be under the red line.
4. Then tighten the fuel tank cap.
5. Rotate the breather on the fuel cap to the "ON" position.

3. Align the charging connector with the interface and plug it in tightly.
4. Connect the battery cable securely.
5. Replace the side cover and screw in the bolts.

3.4. Air Filter Element Cleaning (Initial Check)

While this is typically maintenance, it's good practice to check the air filter during initial setup.

1. Unscrew the bolts on the side cover and open the cover.
2. Remove the air cleaner cover.
3. Take out the air filter element. Inspect for any debris or damage.
4. If dirty, clean it according to the maintenance section. For initial setup, ensure it's properly seated.
5. Put the element back into the air filter.
6. Cover it back and put the side cover back, then tighten the bolts.

4. Operating the Generator

Your LIFAN LF4800iE generator offers multiple starting methods and operational modes.

4.1. Starting Procedures (Electric/One-Button Start)

1. Ensure the fuel cap breather is in the "ON" position.
2. Turn the fuel switch to the "ON" position.
3. Turn the main power switch (POWER.SW) on the control panel to the "ON" position.
4. Press the "ENGINE START/STOP" button once. The generator should start. If it doesn't start immediately, press the button again.
5. Once running, the "START/STOP" light will be green, indicating normal operation.

Figure 4: Multiple Starting Modes. This image illustrates the convenience of electric, one-button, and remote control starting options for the generator.

4.2. Remote Start

The LF4800iE features a wireless remote start for convenience.

1. Ensure the fuel cap breather is in the "ON" position.
2. Turn the fuel switch to the "ON" position.
3. Turn the main power switch (POWER.SW) on the control panel to the "ON" position.
4. Press and hold the "ENGINE START/STOP" button on the generator's control panel for approximately 15 seconds, until you see a red-green flashing light.
5. Then, press the start button on your remote control panel once. The generator should start.
6. To stop the generator via remote, press the "OFF" button on the remote control once.

4.3. Manual (Recoil) Start

If the electric start is unavailable (e.g., low battery), you can manually start the generator.

1. Ensure the fuel cap breather is in the "ON" position.
2. Turn the fuel switch to the "ON" position.
3. Turn the main power switch (POWER.SW) on the control panel to the "ON" position.
4. Pull the recoil starter handle quickly and firmly until the engine starts.
5. Once the engine starts, slowly return the recoil starter handle to its original position.

4.4. ECO Mode

The ECO Mode switch allows the generator to adjust engine speed based on the load, improving fuel efficiency and reducing noise.

• ECO Mode ON: The generator will run at a lower RPM when the load is light, saving fuel and reducing noise.
• ECO Mode OFF: The generator will run at a constant high RPM, providing full power output. Use this for heavy loads or when consistent power is needed.

4.5. Control Panel Overview

The control panel provides various indicators and outlets for operation.

• Multi Meter: Displays voltage, frequency, power, and runtime. It also shows load from 0-100% and fuel level.
• CO Sensor: Indicates carbon monoxide levels. If the CO concentration exceeds limits, the generator will shut down.
• AC Reset: Button to reset the AC circuit breaker.
• USB Ports: Includes 5V 1A and 5V 2.1A USB ports for charging small electronic devices.
