9 Avoid connecting the generator in parallel with any other generator.

1 Correct 2 Incorrect

AE00091

Connection

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.

WARNING

AE00086

Extension cord notes 9 Extension cords should be protected by a tough

flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

9 Electrolyte is poisonous and dangerous since it contains sulfuric acid, which causes severe burns. Avoid any contact with skin, eyes or clothing and always shield your eyes when working near batteries. In case of contact, administer the following FIRST AID. 9 EXTERNAL: Flush with plenty of water. 9 INTERNAL: Drink large quantities of water or

milk and immediately call a physician. 9 EYES: Flush with water for 15 minutes and

seek prompt medical attention. 9 Batteries produce explosive hydrogen gas.

Therefore, keep sparks, flames, cigarettes, etc., away from the battery and provide suffi- cient ventilation when charging it in an enclosed space.

9 KEEP THIS AND ALL BATTERIES OUT OF THE REACH OF CHILDREN.

Operating range of DC power supply (exclusively for charging 12V battery) This power source is designed to charge batteries up to 40Ah that are half-discharged. Do not charge batter- ies of a higher capacity than 40Ah. 12V battery The time required for recharging a battery varies depending on the discharge level of the battery. When the specific gravity of the battery reaches 1.26 to 1.28, charging is complete. When charging, check the bat- terys specific gravity once an hour. The average time for charging a half-discharged 40Ah battery is approximately 5 hours. Be sure to check the battery fluid level before charging.

9 Do not connect any load to the battery or use the engine starter motor while charging. This causes high current to flow through the generator which will burn out the coil.

9 Do not connect a VRLA (Valve Regulated Lead Acid) battery. To charge a VRLA battery, a spe- cial (constant-voltage) battery charger is required.

High altitude operation This engine may require a high altitude carburetor kit to ensure correct engine operation 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 neces- sary carburetor modification. This engine should be operated in its original configuration below 4000 ft. (1219 meters) as damage may occur if high altitude carburetor kit is installed and operated below 4000 ft. (1219 meters).
