SAFETY WARNING
Personal and property safeties of you and others are very vital. Please read the Safety
Warning in the User's Manual and the decals of the generator set carefully.The Safety
Warning can alert you to those potential hazards that could harm you and others. In front
of each Safety Warning, there is one of four words "DANGER" "WARNING",
"ATTENTION", and "CAREFUL". Details are as follows:
Failure to follow the instruction will result in
being in peril of your life or extremely serious
injury.
Failure to follow the instruction will result in
being in peril of your life or very serious injury.
Failure to follow the instruction will result in
minor injury.
Failure to follow the instruction will result in the
damage to your generator set and other properties.
For portable generators where the neutral is floating, the operator's manual shall include the following wording
or equivalent:
The portable generator stator winding is isolated from the frame and from the AC receptacle ground pin; and
Electrical devices that require a connection between one conductor pin and the grounded receptacle pin may not
function properly.
NEUTRAL FLOATING
CO DETECT technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by
engine exhaust when the generator is running. If CO Sensor detects unsafe elevated levels of CO gas, it
automatically shuts off the engine. CO Sensor is not a substitute for an indoor carbon monoxide alarm or for safe
operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents or other
openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust
pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300-2018.

USING THE GENERATOR
Service environment of the generator
1
•Applicable temperature: -5°C ~ 40°C (23°F ~ 104°F);
•Applicable humidity: below 95%;
•Applicable altitude: regions below 1,500 m (It shall be used by reducing power in regions above 1,000 m).
Standard atmospheric condition
•Ambient temperature Tr: 298k (25°C)(77°F)
•Relative air humidity Ɏr: 30%
•Absolute atmospheric pressure Pr: 100kPa
When actual environmental condition is inconsistent with the condition of output power of the generator
set:
•Every 5°C(41°F) of increase in ambient temperature will reduce the power of generator by about 2%.
•Every 30% of increase in relative humidity of air will reduce the power of generator by about 1.5%.
•Every 300 m rising of ASL will reduce the power the generator by about 4.5%.
Generator wiring
2
•When the generator is connected to household power source as a backup power supply, the connection shall be
carried out by a professional electrician or a person familiar with electricity.
•After connecting the load to the generator, check carefully whether electrical connection is safe and reliable.
Improper electrical connection may cause generator damage, burning or fire.
•Avoid connecting this generator to commercial power outlet.
•When extending the cable, be sure not to exceed its length.
①60m cross-section area is 1.5mm²
②100m cross-section area is 2.5mm²
• The appearance of extension cable shall be protected by a layer of tough and elastic rubber cover (IEC25) or
other substitutes.

USING THE GENERATOR
Connection of AC power
WARNING
All electrical equipment shall be disconnected before inserting the plug.
ATTENTION
•Make sure that all electrical equipment, including wires and plugs, are in good condition before
connecting to the generator;
•Make sure that all loads driven by the generator are within rated load range;
•Make sure that load current is within rated current range of rated socket.
Tip: Make sure that the generator set is grounded, and if electrical equipment requires
grounding, the generator set must be grounded.
ձStart up the engine;
ղTurn energy-saving switch to "ON";
ճInsert the plug into AC outlet;
մMake sure that AC indicator is lit up;
յSwitch on electrical equipment.
Tip: Before increasing engine speed, energy-
saving switch must be switched to "OFF". If the
generator set supplies power to multi loads or
electrical equipment, start from large to small
according to the size of each electrical
equipment.
Generator grounding
3
ձPlease use grounding wire with sufficient electrical energy capacity;
ղConnect one end of grounding wire reliable to grounding bolt on control panel
of the generator set;
ճInsert grounding body (iron rod with a diameter of 5 ~ 10mm) 200mm below
into the earth and lead it out with conductor;
մConnect the other end of the grounding wire reliable to the led wire of
grounding body.
In order to prevent any damage to the generator caused by electric shock or improper electrical application, it
is recommended that the generator is grounded with good conductor with insulating sheath.

SERVICE AND MAINTENANCE
WARNING
Please shut down the engine first before performing any maintenance. The engine shall be placed in a
horizontal position. In order to prevent the engine from starting up, separate spark plug cap shall be
separated from spark plug.
Do not use it indoors or use it in a tunnel, cave or other places ventilated poorly. Make sure that work
area is well ventilated. Exhaust gas from the engine contains toxic gases, carbon oxides, and the inhalation
can cause shock, loss of consciousness, and even death.
Spark plug inspection
1
Spark plug is an important part of the generator, which must be inspected regularly.
Remove decorative cover and spark plug cap of
the generator;
1.
Insert the screwdriver into the sleeve, to screw it
counterclockwise, and then remove the spark
plug;
2.
Check whether there is discoloration, and remove carbon deposits.Check
whether there is little pale to moderate brown on ceramic cores around
center electrode of the spark plug;
3.
Check the model of spark plug and clearance.
Spark plug gap: 0.7-0.8mm
Standard spark:
4.
0.7~0.8mm
Tip: The spark plug clearance is required to be measured by line thickness gauge, which shall be adjusted if
necessary.

operating, take care to avoid scalding.
Put the generator on a horizontal plane, start the generator, run it for a few minutes to make it warm, then
turn off the engine;
1.
Turn the knob to ON and remove the oil maintenance cover;
2.
Unscrew oil dipstick;
3.

18
SERVICE AND MAINTENANCE
Place an oil pan under the engine, tilt the generator to quickly pour out oil;
After discharging the oil, put the generator back on level ground;
4.
Refill oil to a proper level, tighten oil dipstick,
cover external cover plate and tighten the knob.
5. Don't go over the scale
Recommended oil: SAE 10W/30
Oil grade: API standard Model SJ or higher
Volume: 0.12gal
Air filter
4
Dirty air filter may prevent air from flowing into the carburetor. In order to prevent failure of the carburetor,
please maintain air filter regularly. If being used in a dusty environment, it shall be maintained frequently.
Unscrew the screws , to remove cover;
1.
Remove screws , to remove cover plate of air filter ;
2.
Clean foam cleaner element with cleaning solvent and blow it dry, Put a few
drops of oil on the filter element.
