Safety Information

Your safety is paramount. Always follow these guidelines to prevent injury or damage:

  • Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas. NEVER operate the generator indoors or in partially enclosed areas. Always use it outdoors in a well-ventilated area, far from windows, doors, and vents.
  • CO Sensor: This generator is equipped with a built-in CO sensor that automatically shuts down the engine if dangerous levels of carbon monoxide are detected. Do not disable or tamper with this safety feature.
  • Fire Hazard: Gasoline is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or allow open flames near the generator.
  • Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all connections are dry and secure. Use only grounded extension cords.
  • Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid touching these surfaces.
  • Children and Pets: Keep children and pets away from the generator at all times.

Setup

  1. Unpacking: Carefully remove the generator and all accessories from the packaging. Inspect for any shipping damage.
  2. Add Engine Oil: The generator is shipped without engine oil. Place the generator on a level surface. Remove the oil fill cap/dipstick. Using the provided funnel, add the recommended amount and type of engine oil (refer to the Specifications section for details). Do not overfill. Securely replace the oil fill cap/dipstick.
  3. Add Fuel: Ensure the generator is off and cool. Use fresh, unleaded gasoline with an octane rating of 87 or higher. Slowly pour gasoline into the fuel tank, being careful not to overfill. Leave a small air gap at the top to allow for fuel expansion. Securely replace the fuel cap.
  4. Positioning: Place the generator outdoors in a well-ventilated area, at least 20 feet away from any buildings, windows, or vents. Ensure the exhaust is directed away from people and structures.

Operating Instructions

Starting the Generator

  1. Ensure the generator is on a level surface and all electrical loads are disconnected.
  2. Turn the fuel valve to the "ON" position.
  3. Move the choke lever to the "CHOKE" position (if the engine is cold).
  4. Pull the recoil starter handle firmly and smoothly until the engine starts.
  5. Once the engine starts, slowly move the choke lever to the "RUN" position.
  6. Allow the engine to warm up for a few minutes before connecting electrical devices.

Connecting Electrical Devices

  • Plug your devices into the appropriate outlets on the control panel.
  • Do not overload the generator. Ensure the total wattage of connected devices does not exceed the generator's running wattage.
  • For sensitive electronics, the inverter technology provides clean power, minimizing the risk of damage.

ECO Mode

The ECO mode switch, when activated, allows the engine speed to automatically adjust to the load, improving fuel efficiency and reducing noise levels. For maximum power output, turn ECO mode off.

Parallel Operation

This generator is parallel-ready. To connect two SUA2600i units for increased power, use the provided parallel cables and follow the instructions in the Quick Start Guide or a dedicated parallel kit manual. Ensure both generators are off before connecting.

Stopping the Generator

  1. Disconnect all electrical loads from the generator.
  2. Allow the engine to run for a few minutes without load to cool down.
  3. Turn the engine switch to the "OFF" position.
  4. Turn the fuel valve to the "OFF" position.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your generator. Always perform maintenance with the engine off and cool.

  • Check Engine Oil: Check oil level before each use. Change oil after the first 20 hours of operation, then every 100 hours or annually.
  • Clean Air Filter: Inspect the air filter every 50 hours or more frequently in dusty conditions. Clean or replace as needed.
  • Inspect Spark Plug: Check the spark plug every 100 hours. Clean or replace if fouled or damaged.
  • Fuel System: If storing the generator for more than 30 days, drain the fuel tank and carburetor or use a fuel stabilizer to prevent fuel degradation.
  • General Cleaning: Keep the generator clean and free of debris. Use a damp cloth to wipe down exterior surfaces.

Troubleshooting

ProblemPossible CauseSolution
Engine will not startNo fuel, low oil, choke not set, spark plug issue, fuel valve off.Add fuel, add oil, adjust choke, check/replace spark plug, turn fuel valve on.
No power outputOverload, circuit breaker tripped, ECO mode on with high load.Reduce load, reset circuit breaker, turn off ECO mode for high loads.
Engine stops unexpectedlyLow oil shutdown, CO sensor activation, out of fuel, overheating.Check oil level, move to well-ventilated area, refuel, allow to cool.
Engine runs roughStale fuel, dirty air filter, fouled spark plug.Use fresh fuel, clean/replace air filter, clean/replace spark plug.
