Generator Ground Circuit
To reduce the risk of shock or electrocution, generator must be properly
grounded. The nut and ground terminal on the frame must always be used to
connect the generator to a suitable ground source. The ground path should be
made with #8 size wire. Connect the terminal of the ground wire between the
lock washer and the nut, and tighten the nut fully. Connect the other end of the
wire securely to a suitable ground source.
The National Electric Code contains several practical ways in which to
establish a good source. If a steel or iron rod is used, it should be at least 5/8
in. diameter, and if a nonferrous rod is used, it should be at least 1/2 in.
diameter and be listed as material for grounding. Drive the rod or pipe to a
depth of 8 ft. If a rock bottom is encountered less than 4 ft. down, bury the rod
or pipe in a trench.
All electrical tools and appliances operated from this generator must be
properly grounded by use of a third wire or be “Double Insulated.”
It is recommended to:
1. Use electrical devices with 3-prong grounded plugs.
2. Use an extension cord with a 3-pole receptacle and a 3-prong plug at
opposite ends to ensure continuity of the ground protection from the generator
to the appliance.
Check and adhere to all applicable federal,state,and local regulations relating
to grounding specifications. Consult a qualified electrician or service personnel
if the grounding instructions are not completely understood or if in doubt as to
whether the generator is properly grounded.
Make sure the control panel, louver and the inverter bottom side cooling well
are in good condition. The generator, inverter or alternator will be damaged if
the cooling vents are blocked.
Make sure thegenerator is upright at all times. Do not store, move or run next
to other equipment.

The engine can be started.
NOTE: The choke “”is not required to start
a warm engine.
Oil warning light (red)
When the oil level falls below the lower level,
the oil warning light comes on and the engine
stops automatically. Unless you refill with oil,
the engine will not start.
NOTE: If the engine stalls or does not start, turn
the engine switch to “ON” and then pull the
recoil starter.
If the oil warning light flickers for a few seconds,
the engine oil is insufficient. Add oil and restart.
Overload indicator light (Red)
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


14
turn 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 blockage in the cooling air inlet
and around the control unit. If any blockage
is found, remove.
4. After checking, restart the engine.
NOTE：The overload indicator light may come on
for a few seconds at first when using
electric devices that require a large
starting current, such as a compressor or
a submergible pump. However, this is not
a malfunction.
AC pilot light (Green)
The AC pilot light ①comes on when the
engine starts and produces power.
DC protector
The DC protector turns to “OFF” ②
automatically when electric device being
connected to the generator is operating and
current above the rated flows. To use this
equipment again, turn on DC protector by
pressing its button to “ON” ①

PREPARATION
Fuel
·Fuel is highly flammable and poisonous.
Check
“SAFETY INFORMATION” (See page 1)
carefully before filling.
·Do not overfill the fuel tank, otherwise it
may overflow when the fuel warms up
and expands.
·After filling the fuel, make sure the fuel
tank cap is tightened securely.
·Immediately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel may
deteriorate painted surfaces or plastic
parts.
·Use only unleaded gasoline. The use of
leaded gasoline will cause severe
damage to internal engine parts.
Remove the fuel tank cap and fill the fuel
into the tank up to the red level.

Using fuel stabilizer
Fuel gets old, oxidizes, and breaks down
over time. Adding a fuel stabilizer (not
included) extends the usable life of fuel and
helps prevent deposits from forming that can
clog the fuel system. Follow fuel stabilizer
manufacturer’s directions for correct ratio of
stabilizer to fuel.
·Mix fuel stabilizer and gasoline prior to filling the tank by using a gas can or
other approved fuel container and shaking gently to combine.
NOTE: To control the amount of fuel stabilizer added to the engine, always mix
fuel stabilizer with gasoline before fueling the tank rather than adding
fuel stabilizer directly into the generator’s fuel tank.
·Replace and secure the fuel tank cap.
·Start and run the engine for at least 5 minutes to allow stabilizer to treat the
entire fuel system.
Do not use E15 or E85 fuel (for fuel containing greater than 10% ethanol) in
this produce. It is a violation of federal law and will damage the unit and void
your warranty.
