A NEW compact generator from Yamaha will provide power for tools out in the field or as backup power in emergencies. The new EF2400iSHC is powered by a 171cc engine that is equipped with Yamaha's Smart Throttle, which automatically adjusts the engine speed to match the load. It will run up to 8.6 hrs. at one-fourth-capacity load on one tank of fuel. A die-cast aluminum frame and aluminum flywheel keep the generator's weight low at 75 lbs. The generator has a low noise level of 53 to 60 dB. It also can be used to run computers and charge cell phones.
