Connection

WARNING Before the generator can be connected to a build- ings electrical system, a licensed electrician must install an isolation (transfer) switch in the build- ings 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.

AE00086

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.

NOTICE 9 Do not overload. The total load of all electrical appliances must not exceed

the supply range of the generator. Overloading will damage the generator. 9 When supplying precision equipment, electronic controllers, PCs, electronic

computers, microcomputer-based equipment or battery chargers, keep the generator a sufficient distance away to prevent electrical interference from the engine. Also ensure that electrical noise from the engine does not inter- fere with any other electrical devices located near the generator.

9 If the generator is to supply medical equipment, advice should first be obtained from the manufacturer, a medical professional or hospital.

9 Some electrical appliances or general-purpose electric motors have high starting currents, and cannot therefore be used, even if they lie within the supply ranges given in the above table. Consult the equipment manufacturer for further advice.

TIP 9 means below. 9 Application wattage indicates when each device is

used by itself. 9 The simultaneous usage of AC and DC power is

possible but total wattage should not exceed the rated output.

High Altitude Operation This engine may require a high altitude carburetor kit to ensure correct engine opera- tion at altitudes above 4000 ft. (1219 meters). If you operate your engine at altitudes above 4000 ft. (1219 meters) consistently, have your local Yamaha dealer perform the necessary carburetor modification. This engine should be operated in its original config- uration below 4000 ft. (1219 meters) as damage may occur if high altitude carburetor kit is installed and operated below 4000 ft. (1219 meters).

Engine Perform the following steps to protect the cylinder, pis- ton ring, etc. from corrosion. 1. Remove the spark plug, pour about one table-

spoon of engine oil (See page 15) into the spark plug hole and install the spark plug. Recoil start the engine by turning over several times (with igni- tion off) to coat the cylinder walls with oil.

2. Pull the recoil starter until you feel compression. Then stop pulling. (This prevents the cylinder and valves from rusting).

3. Clean exterior of the generator and apply a rust inhibitor.

4. Store the generator in a dry, well-ventilated place, with the cover placed over it.

5. The generator must remain in a vertical position when stored, carried or operated.
