Exhaust fumes are poisonous
9Never operate the engine in a closed area or it
may cause unconsciousness and death within a
short time. Operate the engine in a well ventilated
area.
Engine and muffler may be hot
9Place the generator in a place where pedestrians
or children are not likely to touch the generator.
9Avoid placing any flammable materials near the
exhaust outlet during operation.
Fuel is highly flammable and poisonous
9Always turn off the engine when refuelling.
9Never refuel while smoking or in the vicinity of an
open flame.
9Take care not to spill any fuel on the engine or
muffler when refueling.
9Do not leave the generator inside the vehicle or in
the trunk.
9If you swallow any fuel, inhale fuel vapor, or allow
any to get in your eye(s), see your doctor immedi-
ately. If any fuel spills on your skin or clothing,
immediately wash with soap and water and
change your clothes.
9When operating or transporting the generator, be
sure it is kept upright. If it tilts, fuel may leak from
the carburetor or fuel tank.

Connection notes
9Avoid connecting the generator to commercial
power outlet.
9Avoid connecting the generator in parallel with any
other generator.
1Correct
2Incorrect
Connection
Before the generator can be connected to a build-
ing’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the build-
ing’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and build-
ing electrical system damage can occur when nor-
mal operating power returns if unit is used without
an isolation switch.
WARNING
Extension cord notes
Extension cords should be protected by a tough flexi-
ble rubber sheath (IEC 245) or the equivalent to with-
stand mechanical stresses.

G.F.C.I. receptacle
TO REDUCE THE CHANCE OF ELECTRICAL
SHOCK:
9Do not attempt to operate electric devices if
the ground fault circuit interrupter reset button
pops out repeatedly during use.
9Test the ground fault circuit interrupter during
the pre-operation checks according to the
maintenance instructions on page 39.
9Remember that only receptacle labeled “GFCI”
have ground fault circuit interrupter protec-
tion.
The G.F.C.I. (Ground Fault Circuit Interrupter) shuts
off power to the protected receptacles if a ground fault
(electrical leak) is detected.
If the reset button pops out, the electric devices con-
nected into the receptacle may be faulty. If this hap-
pens, check the electric devices carefully. If the elec-
tric devices appears to be in good condition, press the
reset button firmly until a click is heard. This will
restore power. If the reset button pops out again, dis-
connect all the electric devices immediately. Have the
electric devices inspected and repaired by a qualified
repairperson before attempting to use them again.

Voltage select switch
Do not operate the voltage select switch while the
engine is running.
1120/240V
When the voltage select switch is turned to
“120/240V”, the generator supplies both 120V and
240V.
2120V
When the voltage select switch is turned to “120V”, the
generator supplies 120V only.

CANNOT BE USED.
120/240V 120V
TIP
If you operate the generator with the voltage select
switch in the 120/240V-position, the electric current
will be limited for the 120V-receptacles.
When you use either receptacle 1or 2and recepta-
cle 3 at the same time, the total electric current pro-
vided will be equal to or even less than 22.9A.
For example:
If the 240V-receptacle provides 10A, the 120V-recep-
tacles 1and 2can be used up to 12.9A each.
In case the load exceeds 22.9A, the overload indicator
light will turn on and the generator will stop. (At this
moment the segments of the power meter may not
reach 10)
If you operate the generator with the voltage select
switch in the 120V-position, the receptacles 1and 2
can supply rated current (45.8A).

Overload indicator light (red)
The overload indicator light comes on when an over-
load of a connected electrical device is detected, the
inverter control unit overheats, or the AC output volt-
age rises. Then, the AC protector will trip, stopping
power generation in order to protect the generator and
any connected 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.
1Overload indicator light
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 them.
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 submersible pump. However, this is not a mal-
function.

PREPARATION
Fuel
9Fuel is highly flammable and poisonous.
Check “SAFETY INFORMATION”(See page 2)
carefully before filling.
9Do not overfill the fuel tank, otherwise it may
overflow when the fuel warms up and
expands.
9After fill the fuel, make sure the fuel tank cap is
tightened securely.
9Immediately wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may deteriorate
painted surfaces or plastic parts.
9Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts.
Make sure there is sufficient fuel in the tank.
When refueling, be sure to fill the tank to the bottom
edge of the fuel filter.
