2）ECO switch
Energy conservation
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
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 some high
power apparatus at the same time.
•When using 12 V DC output, put the energy-saving switch in
full-speed position.
•"Full speed" means that the energy-saving state is off and the
engine is always at high speed, which is suitable for the
situation when the load of electrical appliances varies greatly.
•In the non-overload state, the output cannot be restored by
pressing the reset key.
•After being switched off five times by the overload switch, the
generator must be restarted.

3. PRE-OPERATION CHECK
Before using, make sure the generator is placed on a horizontal floor
and do not start the engine.
3.1) Check oil level
Remove the dipstick and wipe it with a clean cotton cloth. Re-rotate
into the crankcase and remove. Check the oil level. If the oil level is
below the oil gauge indicator line, please add oil.
•Do not use 2-stroke oil or detergents-free oil, otherwise the
engine life will be shortened.
•Use only high-quality 4-stroke oil that meets or exceeds the
classification required for car engines.
•Select oil suitable viscosity according to the average
temperature in your area.

10
The SAE viscosity grade is shown in the following table：
Store and use oil carefully to prevent dirt or dust from falling into the oil.
When adding oil, wipe the area around the refueling opening. Do not
mix different specifications of oil to prevent negative effects on oil
performance.
Running the engine when the oil level is low can seriously damage the
engine.
The engine oil alarm system automatically shuts off the engine before
the oil level is lowered to safety limits. However, in order to avoid
inconvenience caused by unexpected shutdown, we recommend that
you check the oil level regularly.
3.2）Check fuel level
•Please use unleaded gasoline 95 or higher level.
•Do not use a mixture of oil and gasoline or dirty gasoline.
•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.
•Under certain circumstances, gasoline is extremely flammable
and explosive.
•Please refuel in a well-ventilated place and shut down the
engine. No pyrotechnics are allowed in the engine refueling
area and gasoline storage area.
•Gasoline shall not overflow the tank (the gasoline level must
be lower than the red level indicator). After refueling, tighten
the tank cover.
•After refueling, dry the remaining gasoline with a clean and
soft cloth.
•Avoid prolonged, repeated contact with gasoline or inhalation
of gasoline vapor.
•Do not allow children to touch gasoline.

3.3）Check air cleaner
Check the air filter to make sure it is clean and functional.
A、Loosen the air cleaner maintenance cover screw and remove the
air filter maintenance cover.
B、Snap open the Air Cleaner cover, and remove it.
C、Take out the air filter element. If necessary, clean or replace the
filter element.

13
The engine is not allowed to run without an air filter element, otherwise
dirt will enter the engine and cause rapid wear and tear.
4. STARTING THE ENGINE
•Disconnect the electrical equipment from the alternator's AC
socket before starting the engine.
•For initial use (long unused, start after gasoline is used up),
turn the engine switch knob to "ON" position for 10 to 20
seconds before starting, so that gasoline can enter the engine
carburetor.
It is strictly forbidden to use generators indoor and in closed
environment.
1.The tank cap switch rotates to "ON" position.
Note: When the generator is being transported, the tank cover switch
shall be cranked to the position of the “OFF”.

14
2.Turn the engine switch knob of the generator to the "CHOKE"
position.
3.Pull out the choke lever completely.
Note: when the engine is hotter or the ambient temperature is higher,
the choke lever does not need to be pulled out.
4.Gently pull the start handle until the resistance is felt, and then
quickly pull in the direction shown by the arrow in the figure below.
CHOKE

•Pay attention to pull the starting handle, the pull angle should
not be too large, to prevent the handle from wearing the
housing.
•Do not allow the starting handle to rebound and retract
automatically to avoid damage to the shell. Slowly put the
starting handle back.
5.When the engine is running, turn the engine switch to the running
position.

6.When the generator starts, place the AC circuit protector in the
"connected" position, then the electrical load can be used.
The generator is designed for use at a maximum sea level of 1500 m.
5. USING THE GENERATOR
•In order to prevent electric shock due to improper use, the
generator shall be grounded.
•As a backup power source, the generator cannot be
connected to the grid company's power system.
•Do not overload the generator.
•Do not connect the generator to the power grid company's
household power system, otherwise it may cause people to
die from electric shock when they come into contact with the
wire; and damage the generator or the household appliances.
•Do not run in parallel with other generators.
•Do not lengthen engine exhaust pipe.
•For extended cables, use flexible cables such as rubber
sleeves (compliant with electroSuisse or corresponding
requirements). Cable length limit: 2.5 mm2cable length 60 m;
4.0 mm2cable length 100 m.

17
•Keep generators away from other wires and cables, such as
distribution networks.
•When using AC power, you can use DC power at the same
time.
•If using both AC and DC output sockets, note that the total
power does not exceed the sum of AC and DC power.

18
5.1 DC application
The output voltage of DC socket is 15-20 V. It’s designed for 12V DC
load only.
5.1.1 Start the engine
•When AC power is used, DC power supply can be used.
•If the DC current is overloaded, the DC overload protection
may be triggered. First remove the DC load, wait a few
minutes and press the DC overload protection key for reset.
5.2 AC application
5.2.1 Start the engine, make sure the AC output light (green) is on.
5.2.2 Turn off the power supply switch and plug the device into the
generator's output socket.
5.2.3 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.
Before connecting the alternator output, make sure the electrical
equipment is working properly. If during use, the electrical equipment
suddenly stops working or is not working properly, the electrical
equipment should be immediately disconnected and the engine has to
be stopped.

19
5.3 Operation indicator light, fault indicator light.
•Under normal operating conditions, the operating indicator
(green) light is on.
•If the generator is overloaded, or if the connected electrical
equipment is short-circuited, the operating indicator light(green)
is extinguished, and the fault indicator (red) is turned on, the
output power will be cut off, but the engine will still operate.
•If the fault indicator (red) lights are on, disconnect the electrical
equipment first. If the fault indicator (red) is extinguished and
the operation indication (green) is on, reconnect the electrical
equipment, otherwise shut down the engine and check for
malfunction.
5.4 Low oil level alarm system
•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 too low
(the generator engine switch remains "on").

20
•After the low oil level alarm system shuts down the engine, if
you start the engine again, the low oil alarm indicator (yellow)
lights up and the engine cannot run. If this happens, please
re-fill some proper engine oil.
