FULL POWER SELECTOR SWITCH

The full power selector switch is on the control panel. The switch has two positions: 120 VOLT ONLY, and 120/240 VOLT.

120 VOLT ONLY: This position sends full power to the 120V receptacles only. 240V power is not available. Use this position when powering 120V items only.

120/240 VOLT: This position sends full power to the 120/240V receptacle. It also powers the 120V receptacles at reduced wattage capacity.

GROUND FAULT CIRCUIT INTERRUPTER RECEPTACLE

This generator has a 120-volt ground fault circuit interrupter (GFCI) receptacle. The GFCI receptacle is on the control panel. The GFCI protects you against hazardous electri- cal shock caused when your body becomes a path through which electricity travels to reach ground. This could happen when you touch an appliance or cord that is ‘live’ through faulty mechanism, damp or worn insulation, etc.

When protected by the GFCI, you may still feel a shock, but the GFCI should cut it off quickly. A person in normal health should not receive serious injury. Note: Infants and very small children may still be affected.

Test Procedure

Check the GFCI receptacle every month. This insures it is working right.

1.Push black TEST button. Red RESET button should pop out. This should trip GFCI, resulting in no electrical power at receptacle. Verify this by plugging test lamp with good bulb into recep- tacle. If lamp does not work, GFCI re- ceptacle is good.

WARNING: If RESET button does not pop out, do not use the GFCI receptacle. Contact a quali- fied electrician for repairs.

2.If the GFCI receptacle tests okay, restore power by pushing the RESET button back in. The test lamp should work at this time. IMPORTANT:You must press the RESET button firmly and fully. It should lock into place. If the GFCI does not lock into place, do not use receptacle. Contact a qualified electrician for repairs.

ELECTRIC START

This model has an electric starter. A battery is not supplied with generator. You must pro- vide a 12-volt, 45-amp-hour battery. For more battery information, see Battery, page 6.

RECEPTACLE CIRCUIT BREAKER

The circuit breakers protect the receptacles and alternator. Overloading generator will trip circuit breaker. A short circuit in item being powered will also trip breaker. If this occurs, unplug electrical load from recep- tacle. Let circuit breaker cool down. Push circuit breaker button to reset.

Electric motors need higher starting current. They require up to three-times their rated wattage to start. The starting current needed may be too high. This can cause nuisance circuit breaker tripping. To help prevent this, start electric motors first. Connect ad- ditional items to generator after starting motors. If this continues to happen, reduce the total generator load.

SPARK ARRESTER

We ship a spark arrester with this generator. You must install spark arrester to muffler (see figure 6).

A spark arrester is required if using genera- tor in a national forest and other designated state and local areas. Check local codes.

The spark arrester needs periodic cleaning. A dirty spark arrester reduces engine output and increases fuel consumption. It also makes starting difficult. See engine owner’s manual for cleaning instructions.
