GENERAL SAFETY RULES
DANGER: CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide
(CO). This is a poison gas you cannot see or smell. If you can smell the generator exhaust, you are
breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.
NEVER use a generator inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly levels of
carbon monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply
enough fresh air. ONLY use a generator outside and far away from windows, doors, and vents. These
openings can pull in generator exhaust.
Even if you use a generator correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the generator has been
running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
WARNING: The exhaust from this product contains chemicals known to the State of California
to cause cancer, birth defects, or other reproductive harm.
WARNING: This generator may emit highly flammable and explosive gasoline vapors, which
can cause severe burns or even death if ignited. A nearby open flame can lead to
explosion even if it isn’t directly in contact with gasoline.
● Do not operate near open flame.
● Do not smoke near generator.
● Always operate on a firm, level surface.
● Always turn generator off before refueling. Allow generator to cool for at least 2 minutes before
removing fuel cap. Loosen cap slowly to relieve pressure in tank.

without grounding the frame of the generator.
The generator (stator winding) is isolated from the frame and from the AC receptacle ground pin. Electrical
devices that require a grounded receptacle pin connection will not function if the receptacle ground pin is
not functional.
ECO Switch
When the energy-saving switch is in the energy-saving position, the generator is in the energy-saving state.
When disconnecting or using low power, the engine automatically returns to a low speed state, thus
reducing engine fuel consumption
Full Speed
“full speed” means that the energy-saving state(ECO switch) is in OFF position and the engine is always at
high speed, which is suitable for the situation where the load of electrical appliances varies greatly.
When the energy-saving switch is in full-speed position, the engine will remain in a high speed state.
● In order to reduce the change of voltage, the energy saving switch should be in the position of "full
speed" when the electrical equipment needs a large instantaneous power, or when the generator is
connected with the load of the high power apparatus at the same time.
● When using 12 V DC output, put the energy-saving switch in full-speed position.
WARNING: In the non-overload state, the output can not be restored by pressing the reset key.
Each time the engine is started, the number of effective operation times of the protection cut-off
switch is 5 times, or the engine needs to be restarted.
Parallel Operation
Make sure that the generating set is in a good running state before connecting it to other generating sets.
The total power of electric devices should not exceed rated power of generating set.
When electric motor starts, the overload indicator will light up and normally it will stop within 4 seconds. If
customer service.
During parallel operation, energy-saving switches of generating sets should be in the same position. To
parallel operation, perform the following steps:
1. Connect one generating set to other generating set(s) in parallel. Use the parallel kit to make the parallel
connection (the parallel kit needs to be purchased separately).
2. Start the engine in proper order and make sure that the running indicator (green) is normal.
3. Connect the plug of electric devices to the AC receptacle of parallel kit.
4. Run the electric devices.
NOTE: We advise two parallel generators are same model, or it may cause a low voltage output, which
could damage appliances powered by the generators.

WARNING: This generator may emit highly flammable and explosive gasoline vapors, which
can cause severe burns or even death if ignited. A nearby open flame can lead to explosion even
if not directly in contact with gasoline.
● With the engine stopped, check the fuel level. Refill the fuel tank if necessary.
● Use clean, fresh, regular unleaded gasoline with a minimum octane rating of 87.
● Do not mix oil with gasoline.
● Gasoline shall not overflow the tank (the oil level is lower than the red oil level indicator). After
Ambient Temperature
14
refueling, tighten the tank cover and wipe up any spilled fuel. Prevent dirt and water from entering the
tank.
● Do not use gasoline containing more than 10% ethanol or gasoline containing methanol, otherwise the
engine will be seriously damaged.
To add gasoline, follow these steps:
1. Make sure the generator stopped and cooled entirely,also make sure it is on a level surface.
2. Unscrew fuel cap anticlockwise slowly and set aside.
NOTE: The fuel cap may be tight and hard to unscrew.
3. Slowly add unleaded gasoline to the fuel tank. Be sure not to fill above the upper limit mark (the red
insert). Always allow room for fuel expansion. The capacity of the fuel tank is 1.3gallon.
4. Install the fuel cap.
NOTE: Do not fill the fuel tank to the very top. Gasoline will expand and spill over during use even with
the fuel cap in place. Reinstall fuel cap and wipe clean any spilled gasoline with a dry cloth.
IMPORTANT:
● Do not fill tank indoors.
● Do not fill tank when the engine is running or hot.
● Never use an oil/gasoline mixture.

● Effects of old, stale or contaminated fuel are not warrantable.
● Allow the generating set to cool for at least two minutes before removing fuel cap when adding fuel.
● Loose the fuel cap slowly to relieve any pressure in the tank.
● Fuel and vapors are extremely flammable and explosive. Add fuel in a well ventilated area. Keep fire
and spark away. Failure to do so will result in death or serious injury!
15
Generator Set Grounding
DANGER: Failure to properly ground the generator can result in electric shock.
The generator must be properly connected to an appropriate ground. It helps prevent electrical shock if a
ground fault condition exists in the generating set or in connected electrical devices, especially when the
unit is equipped with a wheel kit. Proper grounding also helps dissipate static electricity, which often
builds up in underground devices.
A ground terminal has been provided on the generating set. For remote grounding, connect of a length of
heavy gauge(4mm
2
12 AWG minimum) copper wire between the generating set ground terminal and a
copper rod driven into the ground.
Local electrical codes may also require proper grounding of the unit. We strongly recommend that you
consult with a qualified electrician for grounding requirements in your area.
Neutral Floating*
–– Neutral circuit IS NOT electrically connected to the engine crankcase/ground of the inverter generator.
–– The generator (stator winding) is isolated from the engine crankcase and from the AC receptacle ground
pin.
–– Electrical devices that require a grounded receptacle pin connection will not function if the receptacle
ground pin is not functional.
Neutral Bonded to Frame*
–– Neutral circuit IS electrically connected to the frame/ground of the generator.
–– The generator system ground connects lower frame cross-member below the alternator. The system
ground is connected to the AC neutral wire.
* See your model’s control panel for specified type of grounding.
Electrical Devices
Disconnect all electrical devices from the generator and switch off the AC circuit breaker before start the
engine.
The generator may be hard to start with electrical devices.
The connected electrical equipment must not exceed the maximum limit of the generator. Please refer to the
specification table for details.
NOTE: After completing the above preparation, the generator is ready to be started.

the overload LED will illuminate and AC output ceases. To correct, unplug your loads, then
press MENU button for 3 seconds to reset as per Page 9.
17
Using The Generator
WARNING: It is prohibited to start or close the generating set when the output terminal of
generating set is connected to an electric device is in “ON” state.
Connect to electrical devices
● Inspect power cord for damage before using. There is a hazard of electrical shock from crushing, cutting
or heat damage.
● Make sure that the generating set has been properly grounded. If the electric devices require grounding,
the generating set must ground.
● Make sure that the electric devices are in “OFF” position.
● Allow the engine to stabilize and warm up for a few minutes after starting.
● Connect and start the electric devices.
● Turn off all electric devices and disconnect them from the generating set.
● If the generating set supplies for several loads or electric devices, start the smallest one first and the
largest one last.
DANGER: If connected devices overheat, turn them off and disconnect them from generating set.
Electrical Shock
To reduce the risk of electrical shock, DO NOT use electrical cords that are worn, frayed, bare or otherwise
damaged. DO NOT touch bare wires or receptacles. DO NOT handle generating set or electrical cords
while standing in water, while barefoot, or while hands or feet are wet.
Loading Capacity
WARNING: Do not overload the generating set.
Exceeding the generating set’s capacity can
damage the generating set and/or electric devices
connected to it.
You must make sure your generating set can supply
enough rated (running) and (starting) watts for the
electrical devices at the same time. Follow these simple
steps to calculate the running and starting watts necessary
for your purposes.
1. Count the electrical devices you will power at the same
time.
2. The amount of power you need to run with the devices
is the total rated (running) watts of these items.
3. Starting power is the power needed shortly when
electric devices start. Since not all devices start at the
same time, starting power can be estimated by the
maximum power of all devices plus the total power
counted in step 2.
WARNING: It is necessary to equip with circuit protector or switch to isolate the generating set
from the electric utility when the generating set is mainly used for backup. Failure to isolate the
generating set from the power utility may result in injury or death to electric utility workers and damage to
the generating set due to back feed of electrical energy.
When using AC power, you can use DC power at the same time. If using both AC and DC output sockets,
Wattage Reference Chart
18
note that the total power does not exceed the sum of AC and DC power.
DC application
The output voltage of DC socket is 15-20 V, for 12V DC load only.
● When AC power is used, DC power supply can be used.
● Overload of DC may make DC over protector act. Firstly, remove the DC load, wait for a few minutes,
and then reset the button of DC protector.
AC application
1. Start the engine, make sure the AC output light (green) is on.
2. Turn off the power supply switch and plug the device into the generator's output socket.
NOTE: In order to obtain the best operation effect and the maximum service life of the generator, the new
generator should run for at least 20 hours under 50% load, so that the engine performance can be optimized.
Stop The Generator
WARNING: Never stop the engine with electrical devices connected and with the connected devices in
