  • Page 15: 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抯 service life. Use high-detergent, premium quality 4-stroke engine oil, certified to meet or exceed U.S.
  • Page 16 Loosen the cover screw and remove the left side maintenance cover. (see page 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.
  • Page 17 Check the fuel level. If the fuel level is low, refuel the fuel tank until the level as specified. 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 18 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 USR . There " are two types of "gasohol : one containing ethanol, and the other containing methanol.

  • Page 21 Move the choke lever to the CLOSED position. Do not use the choke when the engine is warm or the air temperature is high. CHOKE LEVER CLOSED CLOSED Pull the starter grip lightly until you feel resistance, then pull the starter grip briskly toward the arrow as shown below.
  • Page 22 Move the choke lever to the OPEN position as the engine warms up. CHOKE LEVER OPEN If the engine stops and will not restart, check the engine oil level (see page ) before troubleshooting in other areas.

  • Page 23: Carburetor Modification For High Altitude Operation

    Carburetor Modification for High Altitude Operation At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.

  • Page 24: Generator Use

    GENERATOR USE Be sure to ground the generator when the connected equipment is grounded. Connections for standby power to a building抯 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.
  • Page 25 The DC receptacle can be used while the AC power is in use. If you use both at the same time, be sure not to exceed the total power for AC and DC. (See page Most appliance motors require more than their rated wattage for startup.
  • Page 26 AC applications Start the engine and make sure the Output indicator (green) comes Confirm that the appliance to be used is switched off, and plug in the appliance. PLUG OUTPUT INDICATOR OVERLOAD INDICATOR LIGHT (GREEN) LIGHT (RED) Substantial overloading that continuously lights the overload indicator light (red) may damage the generator.
  • Page 27 Output and Overload Indicators The Output indicator (green) will remain ON during normal operating conditions. If the generator is overloaded (in excess of 1.0 kVA), or if there is a short in the connected appliance, the output indicator light (green) will go OFF, the overload indicator light (red) will go ON and current to the connected appliance will be shut off.
  • Page 28 Please read the item "GENERATOR USE" before connecting any equipment to be used. A max output of 2.0 kVA can be obtained by using two units (EV10i) in parallel operation (connection in parallel). There are the terminals into which the special cable is inserted for parallel operation.
  • Page 29 Never connect the different generator models and types. Never connect a cable other than the special cable for parallel operation. Connect and remove the special cable for parallel operation with the engine stopped. For single operation, the special cable for parallel operation must be removed.
