Specifications of the Yamaha EF1000 Generator
A generator can be used not only to power your home during a power outage, but also to power tools on a job site where electrical power isn't available. Yamaha, which has been in business since 1955, started making generators in 1998. The Yamaha EF1000 is a brushless AVR (automatic voltage regulator) AC generator.
The Yamaha EF1000 generator can generate 1,000 watts and has a maximum output of 850 AC. The maximum AC current can generate 7.1 amps to 8.3 amps at 120 volts.
The engine of the Yamaha EF1000 is configured as an OHV (overhead valve) and is cooled with forced air. The engine has four strokes with a single cylinder.
The length of the Yamaha EF1000 is 15.4 inches, and the width is 11 inches. The generator is 15.3 inches tall and weighs 55 lb. The tank holds 1 gallon. When operated continuously at half-load, the generator can run for 6.3 hours. It comes with a two-year warranty as of October 2010.
The Yamaha EF1000 features a heavy-duty construction that allows the generator to run for longer periods reliably. The generator features a brushless alternator, which means that it requires less maintenance. It also has an oil watch warning system that turns off the generator when the level of oil is too low; it won't let you run the machine until you add the proper amount of oil. One of the nicest features is the noise-reduction feature, which not only dampens the noise of the generator but reduces the risk of interference from both television and radios.
