Stop the engine before fueling
Connections to a Home Power
Supply
If the generator is to be connected to a
home power supply as a standby,
connection shall be performed by a
professional electrician or by another
person with proficient electrical skill.
When the loads are connected to the
generator, please carefully check whether
electrical connections are safe and reliable.
Any improper connection may cause
damage to the generator, or cause a fire.

Generator Ground Circuit
In order to prevent electric shock due to shoddy electrical appliances or wrong
use of electricity, the generator must be grounded with a good-quality insulated
conductor.
Make sure the control panel, louver and the inverter bottom side cooling well
and without chips, mud and water come in. it may damage the generator,
inverter or alternator if the cooling vent blocked.
Do not mix the inverter with other stuff If moving, storing or running the unit. It
may cause inverter damage or bring property safety issue when the inverter in
leakage.

CONTROL FUNCTION
3 in 1 switch knob
① Engine switch \fuel valve “OFF”;
Ignitioncircuitisswitchedoff.Fuelisswitchedoff.
The engine will not run.
② Engine switch \fuel valve \ chock “ON”
Ignition circuit is switched on. Fuel is
switched on. chock is switched on.
The engine can be running.
③ Engine switch \fuel valve \ chock “ON”
Ignition circuit is switched on. Fuel is
switched on. chock is switched off.
The engine can be start.
TIP: The chock“”is not required to start a
warm engine.
Oil warning light (red)
When the oil level falls below the lower level,
the oil warning light comes on and then the
engine stops automatically. Unless you refill
with oil, the engine will not start again.
Tip: If the engine stalls or does not start, turn
the engine switch to “ON” and then pull the
recoil starter.
If the oil warning light flickers for a few seconds,
the engine oil is insufficient. Add oil and restart.
Overload indicator light (Red)
The overload indicator light comes on when
an overload of a connected electrical device is
detected, the inverter control unit overheats, or
the AC output voltage rises. Then, the AC
protector will trip, stopping power generation in
order to protect the generator and any connected


15
electric devices. The AC pilot light (Green) will go
off and the overload indicator light (Red) will stay
on, but the engine will not stop running.
When the overload indicator light comes on and
power generation stops, proceed as follows:
1. Turn off any connected electric devices and
stop the engine.
2. Reduce the total wattage of connected
electric devices within the rated output.
3. Check for blockages in the cooling air inlet
and around the control unit. If any blockages
are found, remove.
4. After checking, restart the engine.
TIP：The overload indicator light may come on for
a few seconds at first when using electric
devices that require a large starting current,
such as a compressor or a submergible
pump. However, this is not a malfunction.
AC pilot light (Green)
The AC pilot light ①comes on when the
engine starts and produces power.
DC protector
The DC protector turns to “OFF” ②
automatically when electric device being
connected to the generator is operating and
current above the rated flows. To use this
equipment again, turn on DC protector by
pressing its button to “ON” ①
① “ON”
Direct current is output.


16
②“OFF”
Direct current is not output.
Reduce the load of the connected electric device
below the specified rated output of the generator if
the DC protector turns off. If the DC protector turns
off again, stop using the device immediately and
consult a LONCIN dealer.
Engine smart control (ESC)
“ON”
When the ESC switch is turned to “ON”,
the economy control unit controls the
engine speed according to the connected
load. The results are better fuel
consumption and less noise
.
“OFF”
When the ESC switch is turned to“OFF”,
the engine runs at the rated r/min
(5000r/min)
regard-less of whether is a load connected
or not.
Tip: The ESC must be turned to“OFF”when
using electric devices that require a large
starting current, such as a compressor of a
submergible pump
Fuel tank cap
Remove the fuel tank cap by turning it
counterclockwise.


17
Fuel tank cap air vent knob
The fuel tank cap ②is provided with an air
vent knob to ①stop fuel flow. The air vent
knob must be turned to “ON”. This will allow
fuel to flow to the carburetor and the engine to
run. when the engine is not in use, turn the
air vent knob to “OFF” to stop fuel flow.
Ground (Earth) terminal
Ground (Earth) terminal connects the
earth line for prevention of electric shock.
When the electric device is earthed, always
the generator must be earthed.
Parallel Operation Outlets
This is the terminal ①for connecting special
cables for parallel running of two LC2000i.
The parallel running requires two LC2000i
and the special cables. (The rated output in
parallel running is 3.0Kva and the rated
current is 25.0 A/120V 13A /230V.)
The handing, operation procedure and the
notes on usage are described in the
PARALLEL RUNNING KIT OWNER’S
MANUAL included in the Parallel Running Kit.
Consult a LONCIN dealer for this Parallel
Running Kit.

REPARATION
Fuel
·Fuel is highly flammable and poisonous.
Check
“SAFETY INFORMATION”(See page 1)
carefully before filling.
·Do not overfill the fuel tank, otherwise it
may overflow when the fuel warms up
and expands.
·After fill the fuel, make sure the fuel tank
cap is tightened securely.
·Immediately wipe off spilled fuel with a
clean, dry, soft cloth, since fuel may
deteriorate
painted surfaces or plastic parts.
·Use only unleaded gasoline. The use of
leaded gasoline will cause severedamage
to internal engine parts.
Remove the fuel tank cap and fill the fuel
into the tank up to the red level.
①Red line
②Fuel level

with the sufficient engine oil.
1、Place the generator on a level surface.
2、Remove the screws, and then remove
the cover.
3、Remove the oil filler cap.
4、Fill the specified amount of the
recommended engine oil, and then install
and tighten the oil filler cap.
5、Install the cover and tighten the screws.
Recommended engine oil:
SAE 10W -30
Recommended engine oil grade:
API Service SE type or higher
Engine oil quantity:

PRE-OPERATION CHECK
If any item in the Pre-operation check is not working properly, have it inspected
and repaired before operating the generator.
The condition of a generator is the owner’s responsibility. Vital components
can start to deteriorate quickly and unexpectedly, even if the generator
unused.
TIP：Pre-operation checks should be made each time the generator is used.
Pre-operation check
Fuel (See page 18)
zCheck fuel level in fuel tank.
zRefuel if necessary.
Engine oil (See page 19)
zCheck oil level in engine.
zIf necessary, add recommended oil to specified level.
zCheck generator for oil leakage.
The point where abnormality was recognized by use
zCheck operation.
zIf necessary, consult a LONCIN dealer.
