  • Page 19: Pre-Operation Check

    PRE-OPERATION CHECK Be sure to check the generator on a level surface with the engine stopped. Check the engine oil level. Using nondetergent oil or 2-stroke engine oil could shorten the engine’s service life. Use high-detergent, premium quality 4-stroke engine oil, certified to meet or exceed U.S.
  • Page 20 Remove the oil filler cap, and wipe the dipstick with a clean rag. Check the oil level by inserting the dipstick in the filler hole without screwing it in. If the oil level is below the end of the dipstick, refill with recommended oil up to the top of the oil filler neck.
  • Page 21 Check the fuel level. If the fuel level is low, refill to the shoulder of the fuel strainer. After refueling, tighten the fuel filler cap securely. Use automotive unleaded gasoline with a Research Octane Number of 91 or higher (a Pump Octane Number of 86 or higher). Never use stale or contaminated gasoline or an oil/gasoline mixture.
  • Page 22 Gasolines containing alcohol If you decide to use a gasoline containing alcohol (gasohol), be sure it’s octane rating is at least as high as that recommended by Honda. There are two types of ‘‘gasohol’’: one containing ethanol, and the other containing methanol.
