WARNING
READ AND UNDERSTAND THIS MANUAL COMPLETELY BEFORE OPERATING THE GENERATOR.
SAFETY INFORMATION
EXHAUST FUMES ARE POISONOUS
Never operate the generator in a closed area. It may cause unconsciousness or death within a short period of time.
Operate the generator in a well ventilated area.
FUEL IS HIGHLY FLAMMABLE AND POISONOUS
Always turn off theengine when refueling.
Never refuel while smoking or near an open flame.
Take care not to spill any fuel on the engine or muffler when refueling.
If you swallow any fuel, inhale fuel vapor, or allow any to get in your eyes, seek assistance immediately. If any fuel
spills on your skin orclothing, immediately wash with soap and water and changeyour clothes.
When operating or transporting the generator, be sure it is kept upright. If ittilts, fuel may leak from the carburetoror
fuel tank.
ENGINE AND MUFFLER MAY BE HOT
Place the generator in a place where passers-by orchildren are not likely to touch the generator.
Avoid placing any flammable materials near the exhaust outlet during operation.
Keep the generator at least 3 feet from buildings or other equipment,or the engine may overheat.
Avoid operating the engine with a dust cover.
Be suretocarry the generatoronly by its carry handle.
Put the machine on the flat ground, allowing generator to elminate heat freely.
ELECTRIC SHOCK PREVENTION
Never operate thegenerator in rain or snow.
Never touch the generator with wet hands or electrical shock will occur.
Be sure to ground (earth) the generator. FIG.1
NOTE:
Use ground (earth) lead of sufficient current capacity.
Diameter: 0.12mm (0.005 in)/ampere --8AWG Wire

OIL WARNING SYSTEM
When the oil level falls below the lower level, the engine stops
automatically. Unless you refill with oil, the engine will not start again.
FIG.2
ENGINE AND FUEL COCK SWITCH
The engine switch controls the ignition system. FIG.3
① ON (run)
Ignition circuit is switched on. The engine can be started.
②OFF(stop)
Ignition circuit is switched off. Theengine will not run.
ELECTRIC START SWITCH
The engine switch controls the ignition system. FIG.4
①RUN
Ignition circuit is switched on. The engine can be started.
②STOP
Ignition circuit is switched off. Theengine will not run.
③START
Starting circuit is switched on. The starter motorstarts.
ECONOMY CONTROL SWITCH
When the economy control switch is turned ON, the economy control
unit will control the engine speed according to the connected load. The
results are more efficient fuel consumption and less noise. FIG.5
DC CIRCUIT PROTECTOR
The DC circuit protector turns off automatically when the load exceeds
the generator’s rated output. FIG.6
CAUTION:
Reduce the load to within specified generator’s rated output if the DC
circuit protector turns off.

PRE-OPERATION CHECK
NOTE:
Pre-operation checks should be made each time the generator is
used.
CHECK ENGINE FUEL
Make sure there is enough fuel in the tank. FIG.9
If fuel is low, refill with unleaded automotive gasoline.
Be sure to use the fuel filter screenon the fuel filter neck.
Recommended fuel: Unleaded gasoline.
Fuel tank capacity: (see page 19)
WARNING:
Do not refill tank while engine is running or hot.
Close fuel petcock before refueling.
Be careful not to allow dust, dirt, water or other foreign objects
into fuel.
Do not fill above the top of the fuel filter or it may overflow when
the fuel heats up later and expands.
Wipe offspilled fuel thoroughly beforestarting engine.
Keep away from open flame.
CHECK ENGINE OIL
Make sure the engine oil is at the upper level of the oil filler hole. Add oil
as necessary. FIG.10
Remove oil filler cap andcheck the engine oil level.
If oillevel is below the lower level line, refill with recommended oil to
upper level line. Do not screw in the oil filler cap when checking oil
level.
Change oil if contaminated.

earth spike are not supplied with the unit. FIG.12
CONNECT BATTERY (for electric starting system)
(a) The battery for electric starter should be fixed on the handle of generator.
FIG.13
(b) Connect the battery to the socket on the control panel with the cable
forbattery. FIG.14
NOTE:
Make sure the battery is fully charged before using.

OPERATION
NOTE:
The generator has been shipped without engine oil. Fill with oil or
it will not start.
Do not tilt the generator when adding engine oil. This could result
in overfilling and damage to the engine.
STARTING THE ENGINE
NOTE:
Before starting the engine, do not connect electric appliances.
A. Recoil start
1. Turn the fuel cock lever to the ON position. FIG.15
2. Turn the electric start switch to the RUN position. FIG.16
3. When starting the generator for the first time, press the primer bulb
6 times before attempting to start. FIG.17
4. Turn the choke lever to the││CHOKE position. Not necessary
if the engine is warm. FIG.18
5. Pull the starter handle slowly until resistance is felt. This is the
“Compression” point. Return the handle to its original position and
pull swiftly. Do not fully pull out the rope. After starting, allow the
starter handle to return to its original position while still holding the
handle. Grasp the carrying handle firmly to prevent the generator

2. Make sure the chokelever is in the││RUN position
3. Turn the engine switch to the START position. FIG.21
4. Turn the engine switch to the RUN position. FIG.22
5. Warm up the engine without a load for a few minutes.
C. Auto start
1. Make sure the fuel cock lever is in the ON position.
2. Make sure thechoke lever is in the ││RUN position.
3. Make sure the engine switch is in the RUNposition.
4. Connect the cable to Auto Gen Start plug. As soon as the

USING ELECTRIC POWER
1. AC APPLICATION
(a) Check the AC 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 outlet. F IG.24
CAUTION:
Be surethe electric appliance is turned off before plugging in.
Be surethe total loadis within generator’s ratedoutput.
Be sure the socket load current is within socket rated current.
The economy control switch must be turned to OFF when using
electric devices that require a large starting current, such as a
compressor or a submergible pump. FIG.25
2．OVERLOADINDICATORLIGHT
The overload indicator light comes on when overloaded, short circuit, or
voltage is out of operating tolerance, overheats, or the AC output voltage
rises. The electronic breaker will then activate, stopping power to the
generator 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
follow the following steps: FIG.26
(a) Turn off any connectedelectric devices and stop the engine.
(b) Reduce the total wattage of connected electric devices to within
the application range.
(c) Check for blockages inthe cooling airinlet and around the control unit.If any blockages are found, remove.
(d) Afterchecking, restart theengine. FIG.27
CAUTION:
The generator AC outputautomatically resets when the engine is stopped and then restarted.
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 submergiblepump. This is not a malfunction.

3. DC APPLICATION (option)
This applies to 12V battery charging only.
(a) Disconnect the leads for the battery.
Fully loosen the battery fluid filler cap.
Fill distilled water to the upper limit, if the battery fluid is low level.
Measure the specific gravity for the battery fluid by using the
hydrometer, and calculate the charging time according to the table
shown on right side.
Thespecific gravity for the fully charged battery shall be within 1.26
to 1.28. It is recommended to check every hour. FIG.28
(b) Connect the DC output socket and the battery terminals using the
charging leads. The leads must be connected making sure the (+)
and (-) are correct.FIG.29
CAUTION:
 Be sure the economy control switch is turned OFF while charging
the battery.
