CONNECTION
wBefore the generator can be connected to a build-ing’s electrical system, a licensed electrician mustinstall an isolation (transfer) switch in the build-ing’s main fuse box. The switch is the connectionpoint for generator power and allows selection ofgenerator or main line power to the building. Thiswill prevent the generator from charging the mainpower line (backfeeding) when the main power sup-ply has failed or has been turned off for line repair.Backfeeding can electrocute or injure line mainte-nance personnel. Also, generator and buildingelectrical system damage can occur when normaloperating power returns if unit is used without anisolation switch.
AE00086
EXTENSION CORD NOTES9 When using an extension cord, its total length
should not exceed60 meters for cross section of 1.5 mm squareand100 meters for cross section of 2.5 mm square.
9 This extension cord should be protected by a toughflexible rubber sheath (IEC 245) or the equivalentto withstand mechanical stresses.

9 The overload indicator light 1 comes on whentotal wattage exceeds the application range. (Seepage 19 for more details.)
cCBe sure the total load is within generator rated output otherwise generator damagewill occur.
NOTE:Some precision equipment is voltage sensitive and may require a more uniform voltagesupply than portable generators provide. Examples include some medical equipment,personal computers, and some inverters that sense peak and RMS voltage values.Consult the precision-equipment vendor before relying on any portable generator to pro-vide power to such equipment.

9 Be sure any electric devices are turned offbefore plugging it in.
9 Be sure the total load is within generator ratedoutput.
9 Be sure the receptacle load current is withinreceptacle rated current.
1. Wind the power lead 2 or 3 turns around handle.2. Start the engine.3. Plug in to the AC receptacle.
4. Make sure the AC pilot light is on.

Overload indicator lightThe overload indicator light 1 comes on when an over-load of a connected electrical device is detected, theinverter control unit overheats, or the AC output voltagerises. The electronic breaker will then activate, stoppingpower generation in order to protect the generator andany 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 powergeneration 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 application range.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:9 The generator AC output automatically resets
when the engine is stopped and then restarted.9 The overload indicator light may come on for a few
seconds at first when using electric devices thatrequire a large starting current, such as a com-pressor or a submergible pump. However, this isnot a malfunction.
9 For EF3000iSEB, the overload indicator light mayflash when using electric devices that require alarge starting current. However, this is not a mal-function. (The flashing indicator is a result of thegenerator temporarily discharging more than itsrated wattage.)While the overload indicator light is flashing, elec-tric devices that require a large starting currentcannot be started.

DRAIN THE FUEL1. Remove the fuel tank cap. Drain the fuel from the
fuel tank into an approved gasoline container usinga commercially available hand siphon. Then, installthe fuel tank cap.
w9 Fuel is highly flammable and poisonous. Check
“SAFETY INFORMATION” (See page 5) careful-ly.
9 Wipe up any spilled fuel immediately.
2. Drain fuel from the carburetor by loosening thedrain screw 1 on the carburetor float chamber.
3. Turn the fuel cock knob to “OFF”. Start the engineand leave it run until it stops.This will burn any remaining fuel in the carburetor.
AE01079
ENGINE1. Remove the spark plug, pour about one table-
spoon of SAE 10W30 or 20W40 motor oil into thespark plug hole and reinstall the spark plug. Recoilstart the engine by turning over several times (withignition off) to coat the cylinder walls with oil.
2. Pull the recoil starter until you feel compression.Then stop pulling. (This prevents the cylinder andvalves from rusting).
3. Clean exterior of the generator and apply a rustinhibitor.
4. Store the generator in a dry, well-ventilated place,with the cover placed over it.
5. The generator must remain in a vertical positionwhen stored, carried or operated. The caster locklever should be in the “LOCK” position when storedor operated.
