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.
AE00075
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.
9If you swallow any fuel, inhale fuel vapor, or allow any to get in your eye(s), see your doctor immediately. If any fuel spills on your skin or clothing, immediately wash with soap and water and change your clothes.
9When operating or transporting the machine, be sure it is kept upright. If it tilts, fuel may leak from the carburetor or fuel tank.
AE00843

CONNECTION
w
Before the generator can be connected to a building’s electrical system, a licensed electrician must install an isolation (transfer) switch in the building’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 building electrical system damage can occur when normal operating power returns if unit is used without an isolation switch.
AE00086
EXTENSION CORD NOTES
Extension cords should be protected by a tough flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

e9 Test the ground fault circuit interrupter during
the pre-operation checks according to the maintenance instructions on page 36.
9Remember that only receptacle labeled “GFCI” have ground fault circuit interrupter protection.
763-060
The G.F.C.I. (Ground Fault Circuit Interrupter) 1 shuts off power to the protected receptacles if a ground fault (electrical leak) is detected.
If the reset button 2 pops out 3, the electric devices connected into the receptacle may be faulty. If this happens, check the electric devices carefully. If the electric 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, disconnect all the electric devices immediately. Have the electric devices inspected and repaired by a qualified repairperson before attempting to use them again.

1 “120/240V”
When the voltage select switch is turned to “120/240V” 1, the generator supplies both 120V and 240V.

NOTE:
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 1 or 2 AND receptacle 3 at the same time, the total electric current provided will be equal to or even less than 22.9A.
For example:
If the 240V-receptacle provides 10A, the 120V-recep- tacles 1 and 2 can 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 powermeter may not reach 10)
If you operate the generator with the voltage select switch in the 120V-position, the receptacles 1 and 2 can supply rated current (45.8A).

The generator output is normal when the segments of the barmeter appear.
NOTE:
When 10 segments appear, the generator has almost reached its rated output.

Overload indicator light (red)
The overload indicator light 1 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 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.
NOTE:
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.

9Fuel is highly flammable and poisonous. Check “SAFETY INFORMATION” (See page 1) 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.
cC
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 4.
