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 powersupply has failed or has been turned off for linerepair. Backfeeding can electrocute or injure linemaintenance personnel. Also, generator and build-ing electrical system damage can occur when nor-mal operating power returns if unit is used withoutan isolation 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 atough flexible rubber sheath (IEC 245) or theequivalent to withstand mechanical stresses.

cCBe sure the total load is within generator rated out-put otherwise generator damage will occur.
NOTE:Some precision equipment is voltage sensitive andmay require a more uniform voltage supply thanportable generators provide. Examples include somemedical equipment, personal computers, and someinverters that sense peak and RMS voltage values.Consult the precision-equipment vendor before relyingon any portable generator to provide power to suchequipment.

DRAIN THE FUEL1. Drain the fuel tank, fuel cock, and carburetor float
bowl.
a Carburetor drain plug
2. Pour a cup of SAE 10W30 or 20W40 motor oil intothe tank.
3. Shake the tank to coat the inner surfaces thor-oughly.
4. Drain off the excess oil.
AE00621
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.
