OPERATION CHECKING/ADDING LUBRICANT See Figure 9. CHECKING/ADDING FUEL See Figure 10. NOTICE: Attempting to start the engine before it has been properly filled with lubricant will result in equipment failure. NOTE: If a separate engine manual is provided for this product, please follow the instructions provided in the engine manual instead of the information listed below. Engine lubricant has a major influence on engine performance and service life. For general, all-temperature use, SAE 10W-30 is recommended. Always use a 4-stroke motor lubricant that meets or exceeds the requirements for API service classification SJ. This engine comes with a feature that will shut off the engine when a specific lubricant level is not maintained. The engine will not restart until an appropriate lubricant level is reached. NOTE: Non-detergent or 2-stroke engine lubricants will damage the engine and should not be used.  Unscrew the oil cap/dipstick and remove.  Wipe dipstick clean and re-seat in hole; do not re-thread.  Remove dipstick again and check lubricant level. Lubri- cant level should fall between the hatched areas on the dipstick.  If level is low, add engine lubricant until the fluid level rises to the upper portion of the dipstick.  Replace and secure the oil cap/dipstick. USING FUEL STABILIZER Fuel gets old, oxidizes, and breaks down over time. Adding a fuel stabilizer (not included) extends the usable life of fuel and helps prevent deposits from forming that can clog the fuel system. Follow fuel stabilizer manufacturer's directions for correct ratio of stabilizer to fuel.  Mix fuel stabilizer and gasoline prior to filling the tank by using a gas can or other approved fuel container and shaking gently to combine. NOTE: To control the amount of fuel stabilizer being added to the engine, always mix fuel stabilizer with gasoline before fueling the tank rather than adding fuel stabilizer directly into the generator's fuel tank.  Replace and secure the fuel tank cap.  Start and run the engine for at least 5 minutes to allow stabilizer to treat the entire fuel system. ETHANOL-BLENDED FUELS NOTICE: Do not use E15 or E85 fuel in this product. It is a violation of federal law and will damage the unit and void your warranty. Only use unleaded gasoline containing up to 10% ethanol. DANGER: Risk of fire and serious burns: Never remove fuel cap when unit is running. Shut off engine and allow the unit to cool at least five minutes. Remove cap slowly. WARNING: Gasoline and its vapors are highly flammable and explosive. To prevent serious personal injury and property damage, handle gasoline with care. Keep away from ignition sources, handle outdoors only, do not smoke while adding fuel, and wipe up spills immediately. When adding gas to the generator, make sure the unit is sitting on a flat, level surface. If the engine is hot, let the generator cool for five minutes before adding gas. ALWAYS fill the fuel tank outdoors with the machine turned off.  Remove the fuel cap slowly.  Fill the fuel tank to 1 in. below the top of the fuel neck.  Replace and secure the fuel cap. WARNING: Always shut off engine before fueling. Never remove fuel cap or add fuel to a machine with a running or hot engine. Make sure the unit is sitting on a flat, level surface and only add fuel outdoors. If the engine is hot, let the unit cool for at least five minutes before adding fuel. After fueling, immediately replace fuel cap and tighten securely. Move at least 30 ft. from refueling site before starting engine. Do not smoke and stay away from open flames and sparks! Failure to follow these instructions could result in a fire and cause serious personal injury. NOTE: Always use unleaded gasoline with a pump octane rating of 86 or higher. Never use old, stale, or contaminated gasoline, and do not use an oil/gas mixture. Do not allow dirt or water into the fuel tank. Do not use E85 fuel. DIGITAL DISPLAY See Figure 11. Press and release the mode button to cycle through the following displays: Voltage (V) displays the operating voltage of the generator. Frequency (F) displays the frequency in hertz at which the generator is running. The Run/Maintenance Timer displays the amount of time the generator has run since being started. This timer resets each time the generator is shut off. Page 14 - English
