Do not overload. The total load of all electrical appliances must not exceed the
supply range of the generator. Overloading will damage the generator.

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 manufacturer, a medical professional or hospital.

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.
