FDK Cummins Diesel Genset Manual
This manual provides guidance for the installation, operation, and maintenance of FDK Co.’s Cummins diesel gensets. These gensets adopt Sino-American Cummins engines and American Marathon alternators, or alternatively British Stamford alternators or Sino-American Kaijielie alternators. Please read the manual carefully. For further assistance, contact the technical or after-sales department of FDK. Overseas customers may also send partners for free training at our company.
