ENGINE CIRCUIT BREAKER
This fuse protects the battery charging cir-
cuit. A short circuit will trip the break the
fuse. The fuse will also break if you install
battery wrong. Replace fuse if engine will
not start. The fuse is located inside of the
keyswitch box.

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 receptacle.
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 additional
items to generator after starting motors. If
this continues to happen, reduce the total
generator load.

Note: High ambient temperature will cause
nuisance tripping.
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.
GROUND FAULT CIRCUIT
INTERRUPTER RECEPTACLE
The GFCI receptacle is on the control panel.
The GFCI protects you against hazardous
electrical 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
receptacle is good.
ELECTRIC START
A battery is not supplied with generator.
You must provide a 12-volt, 32-amp-hour
battery. For more battery information, see
Battery,
page 8.
AUTO-IDLE SYSTEM
The Auto-Idle System allows the engine to idle
down or run at a slower speed when the gen-
erator is not being used to supply power. The
Auto-idle system can be turned ON or OFF by
a rocker switch on the control panel. When the
switch is in the OFF position, the engine runs
at full speed all of the time. When the switch
is in the ON position, the engine slows down
to idle speed until an electrical load is applied.
When a load is applied to the generator (an
electrical item is plugged in and turned on) the
engine speeds up to the preset speed required
to produce the correct voltage.
IMPORTANT: A minimum current load
of 1 Amp is required to disengage the auto
idle solenoid and cause the engine to come
up to speed for correct voltage. Powering
items at reduced engine speed will damage
generator and powered items.
WARNING: If RESET button
does not pop out, do not use the
GFCI receptacle. Contact a quali
-
fied electrician for repairs.
