SUA5800iED Dual Fuel Inverter Generator

1、How do I connect the generator battery? (For models with electric start)
When you first receive the generator, the negative battery cable is usually disconnected to prevent discharge during storage.

• Locate the negative cable near the top or rear of the battery.
• Attach the loose end of the negative cable to the negative terminal post of the battery and tighten securely with a bolt.
• ⚠ Caution: Avoid touching both the battery terminal and the generator frame with tools or metal objects at the same time to prevent short circuits.
  
  2、What type of engine oil should I use?
  Initial use (break-in period): SAE 30, 10W-30, or 5W-30 mineral oil is recommended.
  After break-in: You may use either mineral oil or full synthetic oil.
  High temperatures (above 95°F / 35°C): 10W-40 is recommended.
  
  3、What type of gasoline should I use?
  Use unleaded gasoline with an octane rating of 87 or higher, and with ethanol content of no more than 10% (E10).
  ⚠ Tip: Lower ethanol content helps extend the life of the carburetor, fuel system, and seals.
  
  4、How do I add fuel and check the oil for the first time?
  Before the first startup, fill with the recommended engine oil.
  Check the dipstick and ensure the oil level is within the marked range.
  When adding oil or fuel, avoid spills, keep away from open flames, and use a dedicated oil/fuel container for safety.
  
  5、How do I start the generator with recoil (pull) start?
• Set the breaker and master control switch to OFF.
• Select the fuel type:
  Gasoline: Open the gasoline valve → Turn the fuel selector to Gasoline.
  Propane: Close the gasoline valve → Turn the fuel selector to Propane → Connect the propane tank and open the valve.
• Switch the battery to ON (or “RUN” on some models).
• Pull the recoil cord: Pull slowly until resistance is felt, then pull sharply. Repeat if necessary until the engine starts
  
  6、How do I use the electric start function?
  Ensure the battery is properly connected and charged.
  Set the fuel switch to the correct position.Turn the start switch to START.
  Once the engine starts, release the switch and let it return to RUN/ON.
  
  7、Does the generator need to warm up?
  Yes. After starting, let the engine run idle for 1–3 minutes to allow the oil to circulate fully before applying a load.
  
  8、How do I safely connect electrical loads?
  Start the generator before connecting any appliances.
  Connect higher-wattage devices first (e.g., refrigerator, air conditioner), then smaller devices.
  Do not exceed the rated wattage capacity of the generator.
  
  9、How do I start the generator in cold weather?
  Use engine oil suitable for low temperatures (e.g., 5W-30).Place the generator in a warmer environment or use an engine block heater if available.Expect longer starting times in freezing conditions — this is normal.tent goes here.
