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.

Overload Indicator
During engine starting, it is normal for the Overload Indicator(Red) to illuminate for a few seconds.
If Overload Indicator(Red) stays illuminated and the Running Indicator(Green) turns off, the engine will
continue to run without output power. In this condition, remove all applied loads and determine if attached
devices exceed recommended output power. Check for faulty or shorted connections. To restore electrical
output, press the AC reset button to reset.
Start engine. If condition was corrected, the Overload Indicator (
Red
) will not illuminate and electrical
output will be restored. Loads can be applied once the Running Indicator (Green) illuminates.
After above operating, if the Overload Indicator (
Red
) returns, contact our customer service.
Running Indicator
The output indicator lights up when generating set starts and has normal output.
Oil Warning Light
The low oil level alarm system is designed to prevent engine damage due to insufficient oil in the crankcase.
The low oil level alarm system automatically shuts down the engine before the engine oil in the crankshaft
box is lowered to safety (the generator engine switch remains “ON”).
After the low oil level alarm system shuts down the engine, if you start the engine again, the low oil alarm
indicator (yellow) light flashes and the engine cannot run. If this happens, fill recommended oil and then
restart the generator.
V.F.T Display
The V.F.T meter can be used for displaying voltage, frequency(hertz), run time and total run time as
applicable. (Display mode depends on the configuration). The LCD displays each item automatically.
AC Reset Button
The reset button is used to restore output if an overload occurs. To restore output, reduce the loads and
press the rest button.
AC Breaker Button
The AC breaker button is used to protect the 120V 20A AC output receptacle. When these outlet receptacle
are overloaded, the breaker will pop out. In this condition, reduce the loads and then press the AC breaker
button.
10
DC Breaker Button
The DC breaker button is used to protect the 12V DC output receptacle. When this outlet receptacle are
overloaded, the breaker will pop out. In this condition, reduce the loads and then press the DC breaker
button.
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.
Ground Terminal
DANGER: Failure to properly ground the generator can result in electric shock.
The ground terminal is connected to the ground wire to prevent 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
or 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.

exceed the rated power of the generator.
Follow these simple steps to calculate the 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 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.
NOTE: Overload operation will lead to generator stalling or greatly shorten the life of the generator. If
there are multiple loads or electrical equipment connected to the generator set, please keep in mind that:
first turn on the highest starting load, then turn on the second, and finally turn on the lowest starting load.

Transport And Storage
WARNING: Gasoline is highly flammable and extremely explosive. Empty the fuel tank and shut
off fuel tap before storing or transporting this generating set.
To prevent fuel spillage when transporting or during temporary storage, the generating set should be
secured upright in its normal operating position, with the fuel valve and engine switch in “OFF” position.
When transporting
● Do not overfill the tank.
● Do not operate the generating set while it is on vehicle. Take the generating set off the vehicle and use
it in a well-ventilated place. Avoid a place exposed to direct sunlight when putting the generating set on a
vehicle. If the generating set is left in an enclosed vehicle for many hours, high temperature inside the
vehicle could cause fuel to vaporize resulting in a possible explosion.
● The generator must not be transported a long time on rough road. If you have to drive on a road like
this, drain off the gasoline and oil beforehand.
When storage for a long period
The generating set should be started at least once every 2 weeks and allowed to run for at least 20 minutes.
Follow the instructions below for longer term storage if the generating set will be out of service for 2
months or more.
● Allow the generating set to cool completely before storage.
● Clean the generating set according to instruction in maintenance section.
● Drain all fuel completely from the fuel tank, fuel hose and carburetor to prevent gum from forming.
● Turn off the fuel supply at the fuel valve.
● Change the oil.
● Reattach the spark plug.
● Remove the spark plug and pour about 15ml of oil into the cylinder. Crank the engine slowly to
distribute the oil and lubricate the cylinder.
● Store the unit in a clean, dry area out of direct sunlight.
