The overload indicator light comes on
when an overload of a connected
electrical device is detected, the
inverter control unit overheats, or the
AC output voltage rises. Then, the AC
protector will trip, stopping power
generation in order to protect the
generator and any connected electric
devices. The AC pilot light (Green)
will go off and the overload indicator
light (Red) will stay on, but the engine
will not stop running.
When the overload indicator light
comes on and power generation
stops, proceed as follows:
1. Turn off any connected electric
devices and stop the engine.
2. Reduce the total wattage of
connected electric devices within the
rated output.
3. Check for blockages in the cooling
air Inlet and around the control unit. If
any blockages are found remove.
4. After checking, restart the engine.

ALTERNATING CURRENT (AC) CONNECTION
!WARNING Be sure any electric devices are turned off before plugging
them in.
NOTICE Be sure all electric devices including the lines and plug
connections are in good condition before connection to
the generator.
Be sure the total load is within generator rated output.
Be sure the receptacle load current is within receptacle
rated current.
TIP: Make sure to ground (Earth) the generator. When the electric device is
earthed, always the generator must be earthed.
1. Select the voltage change-over switch gear according to the
required voltage requirements. When the voltage change-over switch
is placed at the “120/240” V gear, the load devices of 120V and
120/240v can be used simultaneously.
If the “120/240” V load device is not used, place the voltage change-
over switch to “120” V gear.
2. Start engine and make sure that AC indicator light is green.
3. Insert the plug into AC socket/
4. Make sure that AC indicator light is on.
5. Turn on the electrical equipment.
TIP: Many electric load devices require starting power above their rated
power to start.
TIP: The ESC must be turned to “OFF” before increasing engine speed to
rated rpm.
Most motorized appliances require more than their electrical rating
for startup. When an electrical motor is started, the overload
indicator (red) may come on. This is normal if the overload indicator
(red) goes off within 4 seconds. If the overload indicator (red) stays
on, consult your generator dealer.
If the generator is connected to multiple loads or electricity
consumers, please remember to first connect the one with the
highest starting current. And last connect the one with the lowest
starting current.
If the generator is overload, or if there is a short circuit in a
connected appliance, the overload indicator (red) will go ON. The
overload indicator (red) will stay ON, and after about 4 seconds,
current to the connected appliance(s) will shut off, and the output
indicator (green) will go OFF. Stop both engines and investigate the
problem. Determine if the cause is a short circuit in a connected
appliance or an overload, correct the problem and restart the
generator.

Maintenance Maintenance
Dust can enter the
engine and quickly wear
it out, if the engine runs
without a filter element
or if the filter element is
damaged.
NOTICE
The foam filter element of the dirty
air filter will restrict the air flow to the
fuel system and reduce the engine
performance. If the generator is used
in a dusty area, the maintenance
frequency of the air filter's foam filter
element is higher than that in the
maintenance requirements.
1. Wash the filter element in warm
soapy water and let it dry naturally,
or clean and dry it in a non-
flammable solvent.
2. Dip the filter element into clean oil
and squeeze out excess oil. If there
is too much oil left in the filter
element, start the engine and the
