MODEL FEATURES
With 50 amps and 120/240 dual voltage output, there's not much the EF12000DE can't handle during a power
outage. The EF12000DE is our highest output gasoline-powered 120/240-volt output generator — and it can
be converted to run on propane or LP gas.


Dual voltage -
Provides the versatility of 120 and 240 volt operation.
OHV engine (overhead valve) - Precise valve actuation and heavy-duty design offer improved efficiency, increased
reliability and quite operation.
Cast iron cylinder lining - Provides optimal heat dissipation, consistent performance during continuous use and long
engine life.
Oil Watch Warning System - Automatically shuts off before oil level is low and cannot be re-started until oil is added.
Prevents engine damage and costly repairs while enhancing long-term durability.
Auto Voltage Regulation • Guarantees correct power delivery even with extension cords • Enhanced performance •
Added convenience
Transistor Controlled Ignition (T.C.I.) - Provides clean, efficient spark that ensures fast, easy starting. Low
maintenance, reliable operation.
Noise Suppressor - Reduces electrical interference with TVs and radios.
Auto Decompression - Automatically "opens" valve slightly to reduce initial back pressure when starting making manual
starting effortless.
USFS-approved Spark Arrestor - Offers quiet operation and keeps sparks from exiting exhaust system, reducing
chance of fires caused by an errant spark.
Ground Fault Interrupter (G.F.I.) - If the system senses a leak to "ground," it automatically cuts off power to help
prevent injuries.
Fuel Gauge - Lets operator monitor how much fuel is left.
Electric starter - For convenient ease of operation.
Economy idle - When there is no load on the generator, it automatically returns to idle for improved fuel efficiency and
quieter operation.
