Safety
•Before operating the generator, carefully read and understand this manual, to greatly reduce the chances of
personal injury or equipment damage.
•Exhaust contains poisonous carbon monoxide. Do not operate the generator in poorly-ventilated place.
Ensure that the generator is located in a dry, airy, clean place.
•When the generator running and the muffler is very hot, be careful not to touch it! Let the generator cool off
first.
•To prevent burns, please pay attention to the warning labels on the generator attached to the exhaust
system.
•Never connect to the power outlet in parallel wires or application-specific cable after running in parallel, as
this may lead to electric shocks.
•WARNING! Gasoline is highly flammable! Turn off the generator first before refuelling. Always refuel in a
well-ventilated area. Do not smoke when refuelling.
•If the unit is being used as a back-up power generator for buildings, it must be connected to the building’s
power system only by a qualified electrician and must comply with relevant laws and electrical codes.
Otherwise, the power generator could short-circuit, and if people comes in contact with the power
transmission wire, the generator may explode, burn or cause fires to the building’s electrical equipment.
•Before starting the generator, always perform a pre-operation inspection first to avoid accidents and
damages to the equipment.
•The generator must have an allocated space of at least one meter away from objects and/or equipment.
•The generator must remain horizontal during its operation. If the generator is inclined in any way, it could
result in fuel spillage.
•Operators of the generator should know how to quickly turn off the generator and to understand the
operation of all of its control components. Never allow untrained personnel to operate the generator.
•Children and pets must stay away from the operating area of the generator.
•When the generator is running, keep away from its rotating parts.
•If improperly operated on, the generator can become potentially dangerous. Do not operate the generator
with wet hands!
•Store the generator in a dry location, away from rain and snow.

Set-Up
Pre-Operation Checklist
IMPORTANT! Ensure that the generator is placed horizontally and that it is turned off.
Check the engine oil level
IMPORTANT! Using 2-stroke engine oil could shorten the engine life. Use a high-quality 4-stroke engine oil,
which must meet or exceed US automobile manufacturer's requirements for the classification of the American
Petroleum Institute, SF level. Select the appropriate viscosity for the average temperature of the oil in your area.
1. Loosen the screws of the side access panel to remove the cover.
2. Remove the dipstick with a clean rag to wipe the oil dipstick, without tightening the dipstick and insert it into
the oil port to check the oil level.
3. If the oil level is below the bottom of the dipstick, add more of the recommended oil.
WARNING!
•Insufficient engine oil could seriously damage the engine.
•The Oil Alert system will automatically shut down the engine before the oil level drops below the safety line.
But in order to avoid inconveniences caused by unexpected downtime, we recommend that you regularly
check the oil level.

Check the Fuel Level
1. Use automotive gasoline (preferably unleaded or low-lead gasoline to reduce combustion and reduce
environmental pollution).
2. When the oil level is too low, add fuel to a predetermined level.
3. Never use gasoline or a mixture of oil and gasoline.
4. Do not fill the fuel tank with water.
5. After refuelling, tighten the fuel cap.

Petrol Powered Inverter Generator

WARNING!
•Gasoline is explosive and flammable under certain conditions.
•When refuelling, turn off the generator and do it in a well-ventilated area. Do not store the generator near fire
or areas with strong sources of heat.
•After refuelling, tighten fuel tank cap.
•Be careful not to spill any fuel when refuelling. Spilled fuel may cause fires or explosions. If there is any spilt
fuel, ensure that the fuel has evaporated and that the area is completely dry first before starting the
generator again.
•Avoid prolonged, repeated exposure to gasoline or inhale its vapour. Keep the generator away from the
reach of children.
Check the Air Filter
Check the air filter core, make sure it is clean and that it is operating normally.
1. Unscrew the access panel screws to open the access cover.
2. Remove the three screws on the air filter cartridge.
3. Follow the arrow shown in the figure below to pull out the air filter drawer.
4. Pull out the air filter drawer, check the air filter and, if necessary, clean or replace the filter.
5. Clean or replace the filter before reversing the operation of installing air filtration devices.
WARNING! Do not run the generator when there is no air filter, otherwise it will cause rapid wear of the
generator’s parts through the carburettor into the generator.
Due to the generator's breathing tube leading to the air filter cartridge, the air filter sponge will have a small
amount of oil on it over time. If the generator is in continuous operation for a while now or when there is excess
engine oil, the lower air filter cartridge will also have a small amount of oil on it, which is a normal phenomenon.
Wipe the oil clean from them when the generator is turned off and has sufficiently cooled down.

Operation
Starting the Generator
IMPORTANT! Before starting the engine, disconnect the load between the DC sockets first.
1. Turn on the Oil Switch
2. Set the generator’s engine switch to the "ON" position.

3. Pull the starter cord until you feel resistance, then following the direction of the arrow indicated in
the figure below, quickly pull the handle to start the generator.
CAUTION!
•Do not let go of the starter cord after pulling it, but rather put it back slowly.
•When pulling the starter cord, hold onto the generator tightly to prevent tipping.
NOTE: If the engine cannot be started, check oil level to the exclusion of other failures first.
Operating at High Altitudes
At high altitudes, the standard carburettor air-fuel mixture will be more concentrated, reducing the generator’s
operating performance and fuel consumption increases. By placing the carburettor’s main jet unto a small point,
while adjusting the mixing ratio of the screw, you can change the engine performance in high-altitude areas. If
you always use the generator at an altitude of 1,500 meters above sea level, contact an authorised service
centre or the manufacturer to make changes to the carburettor.
The use of a suitable nozzle will decrease the engine horsepower by 3.5% and will increase it every 305 meters.
If you do not do these adjustments, the impact of altitude on power will be greater.
NOTE: If the engine nozzle is designed for high altitude operation, but will operate at lower altitudes, it may
cause a lowering of output power, overheating and can even make the air-fuel mixture too thin. These conditions
can severely damage the generator.
Using the Generator
WARNING!
•To prevent electric shocks, the generator should be grounded. A thick cable should be connected between
the ground terminal and the external ground-source of the generator.
•If the generator is being used as a power back-up for buildings, ensure that it is connected to the building’s
power system by a qualified electrician and must comply with relevant laws and electrical codes. Otherwise,
the power generator could short-circuit, and if people comes in contact with the power transmission wire, the
generator may explode, burn or cause fires to the building’s electrical equipment.
•If the generator is continuously used, do not exceed the rated power given. In other cases, you should
consider rated total power of the connected device.
•Do not exceed the rated current of the electrical socket.
•Do not connect the generator at home, as this may damage the generator or home appliances.

•Do not use the generator for purposes other than what it were intended to do. Please observe the following
additional requirements:
−Do not do a parallel connection with the generator.
−Do not lengthen the exhaust pipe.
−If you are going to use an extension cable, use a rubber sleeve flexible cable (the cable should meet the
requirements of local laws and regulations).
−Minimum length of extension cable: 1.5mm²; cable length of 60m; 2.5 mm² cable length of 100 meters.
−Keep the generator away from other wires and cables, such as those for a distribution network.
•When using an AC power, DC power can also be used. If you want to use both AC and DC power supply, do
not exceed the total power sum of both the AC and DC.
•The motor equipment’s power should not be higher than the unit power calibration at the start.
AC Power Applications
1. Ensure that its output indicator (green) is lit.
2. Ensure that the required device connected to the switch is turned off, and then plug in the device at the
generator outlet.
WARNING!
•If the overload indicator light (red) stays on, the generator will be damaged; and if the temporarily mild
overload indicator light (red) is lit, it will shorten the life of the generator.
•Before connecting a device to the generator, ensure that it is in good working condition first. If it appears
abnormal, suddenly stops or slows down, immediately turn off the generator’s power switch, and then
disconnect the device.
Output, Overload Indicator, Oil Warning Light
•Under normal operating conditions, the output indicator light (green) will be lit.
•If the generator is overloaded or there is an internal short-circuit in the connected device, the output indicator
(green) will be off and the overload indicator (red) will light up instead. If this happens, cut-off the current
connection to the device.
•If the red light is lit-up, turn off the generator and check the cause of the overload.
•If the oil alert lamp is lit-up, the engine will automatically shut down. Check and see if oil needs to be added.

NOTE:
•Before connecting a device to the generator, check whether the device is in good working condition. If the
device’s required power exceeds that of the generator, connect the needed cable equipment, then start the
generator.
•Ensure that the switch is connected to the device before it is put to use in the OFF position.
WARNING! After starting the engine, if the overload indicator light (red) is lit-up, check whether there is a load
connected to the AC outlet. If so, unplug the load cable, and then turn off the generator. In this case, the
overload indicator light will flash for a few seconds until the overload indicator will stop flashing. Then, start the
generator.
If after several consecutive starts the generator overload indicator light is still on, and after checking the AC
outlet and ensuring that no load is connected, have the generator serviced by the manufacturer or an authorised
service centre.
1. Connect the ground terminal

2. Requirements for starting the generator:
When the output indicator light (green) does not light-up, and the overload indicator (red) is lit-up instead,
turn off the toggle switch of the engine, then wait after the overload indicator light goes out. After that, follow
the Starting the Generator procedure to start the generator again.
3. Ensure that the connected device is turned off first, then plug it into the generator AC outlet.
CAUTION! If the connected device is turned on before connecting it to the generator, the device will
suddenly start, potentially causing injury.
4. When the output indicator (green) lights up, turn on the generator.
NOTE: If there is failure in the overload operation or in the internal equipment, the output indicator (green)
will go out and the overload indicator light (red) will then light-up. Also, there is no power output and the
engine will not stop, so you must press the engine switch to the “OFF” position to turn off the generator’s
engine.
Match a pure inductive load with the machine with a pure inductive load. The machine cannot be rated
power with the same unit of power. The machine-rated power is only 40% to 75% of pure inductive load.
Rated Output
•Altitude: 0 m
•Ambient temperature: 25°C
•Relative Humidity: 30%
Only under specified ambient temperature and cooling can the generator be loaded to the rated power. If the
working conditions do not meet these standards or there is poor engine cooling (being run in a limited area), it
should be adjusted to reduce the generator’s power.

NOTE:
•When the relative humidity is 60%, the ambient temperature has an improved coefficient of C-0.01
•When the relative humidity is 80%, the ambient temperature has an improved coefficient of C-0.02
•When the relative humidity is 90%, the ambient temperature has an improved coefficient of C-0.03
•When the relative humidity is 100%, the ambient temperature has an improved coefficient of C-0.04
Algorithm Example:
When the generator power rating PN = 2.0KW, altitude is 1000m, the ambient temperature is 35°C, relative
humidity is 80%.
In this environment, the generator’s rated output of P = PN x (C-0.02) = 2.0 × (0.82-0.02) = 1.6KW
Current Use
NOTE: 12V DC outlets are only for automatic battery charging. A DC socket must be present to monitor the
battery voltage. If the battery voltage exceeds 16V, you must immediately stop supplying power to it. Otherwise,
it can easily lead the battery to explode.

Transportation and Storage
NOTE: To prevent fuel leakage during transportation or temporary storage, turn off the oil switch.
When transporting the generator:
•Do not fill up the fuel tank too much (filler should have no fuel in it).
•If the generator is still being transported, do not operate the generator. When the generator done being
transported, store it in a well-ventilated area.
•If the generator is transported in vehicles, avoid exposing it to direct sunlight. If the generator placed inside a
sealed compartment, the high temperature inside may lead to the fuel becoming volatile, potentially causing
an explosion.
•Do not transport the generator for a long time on rough roads and terrains. If necessary, drain all the fuel first
before transporting the generator.
Before storing the generator for an extended time:
•Ensure that the storage area is dry and clean.
•Drain all of the fuel.
WARNING! Under certain conditions, fuel can become extremely flammable! Ensure that there are no
sources of fire or strong heat in the storage area of the generator.
1. Fuel should be kept in a single, spare container. Turn ON the oil switch and start the engine. Run it to burn
any remaining fuel. The engine will then automatically turn OFF afterwards.
