Detailed Specifications
 Overview 
  • Full power, full time dual voltage operation.
  • Large, super quiet muffler.
  • The electric starter, with recoil backup, and automatic choke make starting effortless. The automatic decompression system helps to make manual starting easy.
  • The transistor controlled ignition system and the brushless generator are dependable and maintenance free.
  • The Oil Watch oil warning system automatically shuts off the engine when the oil level is low.
  • An electrical interference suppressor controls interference with TV and radio.

 

  • A USFS approved spark arrestor prevents the release of sparks from the exhaust.
  • Economy idle reduces engine speed when there's no electricity demand on the generator.
  • Automatic Voltage Regulation maintains smooth, stable power.
  • You could call the EF4000DE the "all-star utility infielder" of the generator field. That's because it does everything well ­ quietly and efficiently ­ and still has power in reserve. The heart of the EF4000DE is an all-new 251cc overhead valve engine with a unique combustion chamber design that enhances power output and efficiency. And thanks to its extra-large fuel tank.
