Setup

  1. Unpacking: Carefully remove the generator from its packaging. Check for any shipping damage.
  2. Placement: Place the generator on a firm, level, and non-combustible surface. Ensure there is sufficient ventilation around the unit. Keep it away from walls, flammable materials, and other obstructions.
  3. Fueling:
    • Ensure the engine is OFF and cool before refueling.
    • Use a 2-stroke fuel mixture with a ratio of 1:40 (e.g., 25 ml 2-stroke oil per 1 liter of gasoline).
    • Open the fuel cap and carefully pour the fuel mixture into the tank using a funnel to avoid spills.
    • Do not overfill. Leave some space for fuel expansion.
    • Securely close the fuel cap. Wipe up any spilled fuel immediately.

Operating Instructions

Starting the Generator:

  1. Ensure the generator is on a stable surface and properly fueled.
  2. Set the engine switch to the "ON" position.
  3. If the engine is cold, move the choke lever to the "CHOKE" position. For a warm engine, the choke may not be necessary.
  4. Firmly pull the recoil starter handle until the engine starts. Do not let the rope snap back; guide it gently.
  5. Once the engine starts, slowly move the choke lever back to the "RUN" position.
  6. Allow the engine to warm up for a few minutes before connecting any electrical devices.

Connecting Devices:

  • Ensure the total wattage of connected devices does not exceed the generator's continuous power output (650 W).
  • Plug your 230V devices into the generator's outlet.
  • Monitor the generator for any signs of strain or overload. The overload protection will activate if the load is too high.

Stopping the Generator:

  1. Disconnect all electrical devices from the generator.
  2. Set the engine switch to the "OFF" position.
  3. Allow the generator to cool down completely before storing or transporting.

Maintenance

Regular maintenance ensures the optimal performance and extends the lifespan of your generator. Always ensure the engine is off and cool before performing any maintenance.

  • Spark Plug: Inspect and clean the spark plug regularly. Replace if worn or fouled.

  • Fuel System: If storing the generator for an extended period, drain the fuel tank and carburetor to prevent fuel degradation and clogging.
  • General Cleaning: Keep the exterior of the generator clean. Remove any dirt or debris from cooling fins to prevent overheating.
  • Storage: Store the generator in a dry, well-ventilated area, away from direct sunlight and extreme temperatures.
