0 Place the generator on a firm, level surface: avoid loose sand or snow. If the generator is tilted or overturned, fuel spillage may result. Also, if the gen- erator is overturned or sinks into a soft surface, sand, dirt, or water may enter the generator. 0 To prevent fire hazards and to provide adequate ventilation, keep the generator at least 1 meter (3 feet) away from buildings and other equip- ment during operation. Do not place flammable objects close to the gen- erator. 0 Know how

CAUTION: Check the generator on a level surface with the engine stopped. 1. Engine Oil CAUTION: Engine oil is a major factor affecting performance and service life. Non-detergent and 2-stroke engine oils are not recommended. Use Honda 4-stroke oil an equivalent high-detergent, premium quality motor oil certified to meet or exceed U.S. automobil manufacture’s requirements for Service Classification SG*SF/CC.CD. Motor oils classified SG.SF/CC*CD will show this designation on the container.

2. Fuel Check the fuel meter and refill the tank if the fuel level is low. Your engine is designed to use any gasoline that has a pump octane number (y 1 of 86 or higher, or that has a research octane number of 91 or higher. Gasoline pumps at service station normally display the pump oc- tane number. We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system components. Never use stale or contaminated gasoline o

l Gasoline is extremely flammable and is explosive under certain conditions. l Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refuel- ed or where gasoline is stored. l Do not overfill the fuel tank (there should be no fuel in the filler neck). After refueling, make sure the tank cap is closed properly and securely. l Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may.ignite. If any

5. GENERATOR USE l To prevent electrical shock from faulty appliances, the generator should be grounded. Connect a length of heavy wire between the ground terminal and the ground source. l Connections for standby power to a building’s electrical system must be made by a qualified electrician and must comply with all applicable laws and electrical codes. Improper connections can allow electrical current from the generator to backfeed into the utility lines. Such backfeed may electrocute u

Oil Alert System The Oil Alert system is designed to prevent engine damage caused by an in- sufficient amount of oil in the crankcase. Before the oil level in the crankcase falls below a safe limit, the Oil Alert system will automatically shut down the engine (the engine switch will remain in the ON position). If the Oil Alert system shuts down the engine, the Oil Alert lamp will flash when you operate the starter, and the engine will not run. If this occurs, add engine oil (P. 8). OIL A
