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.

STARTING UP THE GENERATOR
LPG startup is difficult ?
When both gasoline and propane are present in the generator it is recommended to start the generator on
gasoline first, allow the engine to stabilize then switch to propane.
1. Ensure the LPG supply hose is securely attached and Close the LPG valve
completely.
2. Fuel source rocker switch to “GASOLINE”.
3. Follow the startup steps to start the generator.
4. Open the LPG valve completely.
5. Fuel source switch to “LPG”.
OPEN
CLOSE
Electric start and remote start no response ?
1. Check whether the positive and negative electrodes of the battery are correctly connected.
2. Check whether the battery is charged.
3. Check whether the remote control is powered on.
COMMON PROBLEMS WITH STARTING THE GENERATOR:
Start the generator to run normally without output ?
Check whether the green light of the GFCI socket is on.
If the green light is not on, press the RESET button after the generator is started to
make the green light on.
Tip: When the generator is not started, the GFCI socket is in the protected state and
the "RESET" button cannot be pressed.

16
STARTING UP THE GENERATOR
Parallel Operation
The parallel connection ports allow you to connect two generators to increase the total available electrical power.
Follow the instructions included with your parallel connection kit for proper installation and operation.
Overload Indicator
Note: The OVERLOAD light may turn on for a few seconds as a large device starts. This is normal for loads
approaching the capacity of this generator.
1. The total combined load through the outlets on the generator must not exceed the running power of the unit.
2. If the OVERLOAD light turns on and the generator stops producing power, it has been overloaded.
Low Oil Indicator
1. If the engine oil level is too low, the LOW OIL light turns on and the engine will automatically shut off.
2. The engine cannot be restarted until the proper amount of oil has been added. Add the appropriate type of oil
until the oil level is at the proper level. SAE 10W-30 oil is recommended for general use.
Do not run the engine with too little oil. Engine will shut off if engine oil level is too low.
Low Idle
1. Turn on a Low Idle Switch to limit noise and fuel consumption with a light generator load.
2. Turn off the low idle mode to run the engine at full speed under the following conditions:
● Starting the generator.
● If the load exceeds 50%, it is recommended to turn off the low idle mode.
AT T E NT IO N
3. Turn off and disconnect all electrical devices and stop the engine. Compare device requirements to generator
rating and reduce the total wattage of connected devices if necessary. Move anything that may be limiting
generator ventilation away.
4. Check if any circuit breakers have tripped and make sure that ALL circuit breakers are reset before starting the
generator again.
5. Restart the engine and reconnect devices while being careful to not overload the generator.

17
SHUTTING DOWN THE GENERATOR
Unplug the power cord;

USING THE GENERATOR
Service Environment of the Generator
1
• Applicable temperature: -5°C~ 40°C;
• 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)
• Relative air humidity Фr: 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 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.
① 60m cross-section area is 1.5mm²
② 100m 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.
① Start up the engine;
② Turn energy-saving switch to "ON";
③ Insert the plug into AC outlet;
④ Make sure that AC indicator is lit up;
⑤ Switch 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
① Please use grounding wire with sufficient electrical energy capacity;
② Connect one end of grounding wire reliable to grounding bolt on control panel
of the generator set;
③ Insert grounding body (iron rod with a diameter of 5 ~ 10mm) 200mm below
into the earth and lead it out with conductor;
④ Connect 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.
Tip: How to change the grounding method please refer to the website: https://www.genmaxpower.com/page/faq
