9
Do not overload. The total load of all electrical appliances must not exceed the
supply range of the generator. Overloading could result in damage to the gen-
erator.
9
Some types of precision equipment such as electronic controllers, PCs, elec-
tronic computers, microcomputer-based equipment and battery chargers are
sensitive to voltage fluctuations and may require more stable voltage supply
than the voltage supplied from the portable generator.
When using such equipment, consult with a Yamaha dealer.
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 interfere
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 equipment manufacturer, a medical professional or hospi-
tal.
9
Some electrical appliances or general-purpose electric motors have high
starting currents, that may exceed the total capacity of your Yamaha genera-
tor. Consult the equipment manufacturer for further advice.
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).
