piEiEil Do notstartthe vehicle while thebatterycharging cables are connected and the generator is running. The vehicle or the generator may bedamaged. An overloaded DC circuit, excessive current draw by the battery, or a wiring problem will trip the DC circuit protector (PUSH button extends out). If this happens, wait a few minutes before pushing in the circuit protector to resume operation. If the circuit protector continues to go OFF, discontinue charging and see your authorized Honda generator dealer.
HIGH ALTITUDE OPERATION At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumptionwill increase. A very rich mixture will also foul the spark plug andcause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions. High altitude performance can be improved by specific modifications to the carburetor.
PRE-OPERATION CHECK ENGINE OIL Engine oil is a major factor affecting engine performanceand service life. Non detergent and 2-stroke engine oils will damage the engine and are not recommended. Check the oil level BEFORE EACH USE with the generator on a level surface and the engine stopped. Use 4-stroke motor oil that meets or exceeds the requirements for API serviceclassification SJ. Always check the API SERVICE label on theoilcontainer to besure it inletters the cludes SJ.
REFUELING Fuel tank capacity: 2.91 US gal (11.O 0 ,2.42 Imp gal) With the engine stopped, check the fuel level gauge. Refill the fuel tank if the fuel level is low.
