! WARNING ─────────────────────────────────────────────────
PLEASE READ AND UNDERSTAND THIS MANUAL COMPLETELY BEFORE OPERATING
THE MACHINE.
───────────────────────────────────────────────────────────
1．SAFETY INFORMATION
1）EXHAUST FUMESARE POISONOUS
zNever operate the engine in a closed area because it may cause unconsciousness and death
within a short time. Operate the engine in a well ventilated area.
2）FUEL IS HIGHLY FLAMMABLE AND POISONOUS
zAlways turn off the engine when refueling
zNever refuel while smoking or in the vicinity of an open flame.
zTake care not to spill any fuel on the engine or muffler when refueling.
zIf you swallow any fuel, inhale fuel vapor, or allow any fuel to get in your eyes, see your doctor
immediately. If any fuel spills on your skin or clothing, immediately wash with soap and water
and change your clothes.
zWhen operating or transporting the machine, be sure it is kept upright. If tilted, fuel may leak
from the carburetor or fuel tank.
3）ENGINE AND MUFFLER MAY BE HOT
zPlace the machine in a place where pedestrians or children are
not likely to touch the machine. hot
cool air
zAvoid placing any flammable materials near the exhaust outlet
during operation.
zKeep the machine at least 1 m ( 3 ft ) from buildings or other
equipment, or the engine may overheat.

ETQ

zAvoid operating the engine with a dust cover.
zBe sure to carry the generator only by its handle.
zPut the machine on a flat surface. This will allow the machine to distribute the heat evenly.
4）ELECTRIC SHOCK PREVENTION
zNever operate the engine in rain or snow.
zNever touch the machine with wet hands or electrical shock will
occur.
zBe sure to ground (earth) the generator.
The National Electric Code requires that the frame of generator
and the external electrically conductive parts of the generator be connected to an approved earth
ground. Local codes may differ and require other grounding specifications.
Using a No. 12 AWG (American Wire Gauge) stranded copper wire to the ground terminal and to
an earth-driven copper or brass grounding rod provides sufficient safety against shock. However,
local codes may differ. Contact a local electrician to find out specifications for grounding your
generator
5）CONNECTION NOTES
zAvoid connecting the generator to commercial power outlet.
zAvoid connecting the generator in parallel with any other generator.

1）OIL WARNING SYSTEM
When the oil level falls below the low level line, the engine will
stop automatically. Unless you refill with oil, the engine will not
start again.
2）ENGINE SWITCH
The engine switch controls the ignition system.
“ON”
Ignition circuit is switched on. The engine can be started.
“OFF”
2
1
Ignition circuit is switched off. The engine will not run.
3）AUTO THROTTLE
When the AUTO THROTTLE SWITCH is turned to ECO position,
the economy control will adjust the engine speed according to the
connected load. The results are better fuel consumption and less
noise.

4）FUEL TANK CAPAIR VENT KNOB
The fuel tank cap is provided with an air vent knob to stop fuel
flow. The air vent knob must be turned once clockwise from the
closed position. This will allow fuel to flow to the carburetor and
the engine to run.
When the engine is not in use, tighten the air vent knob
counterclockwise until it is finger-tight to stop fuel flow.

5）FUEL COCK
ON OFF
The fuel cock is used to supply fuel from the tank to the
carburetor.
6）DC CIRCUIT PROTECTOR
The DC circuit protector turns off automatically when the load
exceeds the generator rated output.
CAUTION: ─────────────────────────────────────────────────
zReduce the load to within specified generator rated output if the DC circuit protector turn off.
──────────────────────────────────────────────────────────
3. PRE-OPERATION CHECK
NOTE: ─────────────────────────────────
zAdd more than 2 liters of fuel to run this machine for the first
time.
zPre-operation checks should be made each time the generator
is used.
───────────────────────────────────────
1）CHECK ENGINE FUEL
zMake sure there is sufficient fuel in the tank.
zIf fuel is low, refill with unleaded automotive gasoline.
zBe sure to use the fuel filter screen on the fuel filter neck.
zRecommended fuel: Unleaded gasoline.
zFuel tank capacity: 5.7 liters
WARNING: ──────────────────────────────────────────────────
zDo not refill the generator while the engine is running or hot.
zClose fuel cock before refueling the generator.

zBe careful not to allow dust, dirt, water or foreign objects into the fuel.
zDo not fill above the top of the fuel filter or the fuel may overflow when the fuel heats up and
expands.
zWipe off spilt fuel thoroughly before starting engine.
zKeep open flames away.
───────────────────────────────────────────────────────────
2）CHECK ENGINE OIL
Make sure the engine oil is at the upper level of the oil filler hole.
Add oil as necessary.
zRemove oil filler cap and check the engine oil level.
zIf oil level is below the lower level line, refill with suitable oil to
upper level line. Do not screw in the oil filler cap when checking

“Compression” point. Return the handle to its original position
and pull swiftly. Do not fully pull out the rope. After starting, guide
the starter handle to its original position while still holding the
handle. Grasp the carrying handle firmly to prevent the generator
from falling over when pulling the recoil starter.
6. Warm up the engine.
7. Move the choke lever back to the OPEN position.
8. Warm up the engine without a load for a few minutes.

2）USING ELECTRIC POWER
1. AC APPLICATION
(a) Check the output pilot lamp for proper voltage.
(b) Turn off the switch(es) of the electrical appliance(s) before
connecting to the generator.
(c) Insert the plug(s) of the electrical appliance(s) into the
receptacle(s).

ECO
CAUTION: ─────────────────────────────
zBe sure the electrical load is turned off before plugging it in.
zBe sure the total load is within the generator rated output.
zBe sure the socket load current is within socket rated current.
zThe AUTO THROTTLE SWITCH must be turned to the HIGH position when using electric
devices that require a large starting current, such as a compressor or a submergible pump.
───────────────────────────────────────────────────────────
2．OVERLOAD INDICATOR LIGHT
The overload indicator light comes on when an overload of a connected electrical device is
detected, the inverter unit overheats, or the AC output voltage rises. The electronic breaker will then
activate, stopping power to the generation in order to protect the generator and any connected
electric devices. The output pilot light (green) will flicker and the overload indicator light (red) will
turn on, then the engine will stop running. If so please follow the following steps
(a) Turn off any connected electric devices and stop the engine
(b) Reduce the total wattage of connected electric devices within the application range.
(c) Check for blockages in the cooling air inlet and around the control unit. If any blockages are
found, remove.
(d) After checking, restart the engine.
CAUTION: ───────────────────────────────────────────────────
zThe generator AC output automatically resets when the engine is stopped and then restarted.
