OWNER’S MANUAL
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.
IMPORTANT: Do not move the full power
selector switch while powering electrical
items. Unplug all items before moving switch.
Failure to do so can damage switch.
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.
GENERATOR

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.
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.
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.
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.
