Chapter  1—INTRODUCTION THE ENGINEMAN—YOUR JOB Since you first became a rated person you have mastered basic skills, became familiar with much of the terminology applicable to internal combus- tion engines and other equipment, and learned to answer many of the technical questions asked by lower rated personnel. Along with this increase in knowledge, you have gradually assumed greater responsibilities.  The  rate  for  which  you  are  now preparing  demands  more  knowledge  and  skill,  a willingness  to  assume  greater  responsibility,  and the ability to lead people. As an EN1 or ENC, you must be familiar with all the functions of the engineering department and be proficient in a wide variety of tasks. Your duties will include using proper procedures for troubleshooting, maintenance and repair, plan- ning,  organizing,  and  carrying  out  the  work involved  in  these  procedures.  You  will  maintain records and submit reports; you will supervise the stowage of supplies and repair parts; and you will take an active part in the training of lower rated personnel.  In  brief,  you  will  be  a  technical specialist and a military leader. MILITARY DUTIES AND RESPONSIBILITIES Information   related   to   the   military requirements for advancement is included in train- ing manuals specifically prepared to cover such requirements.   These   manuals   are   listed   and described briefly later in this chapter. TECHNICAL  DUTIES  AND RESPONSIBILITIES A  petty  officer  must  become  a  technical specialist in his/her rating. Technical duties which an Engineman must learn to perform efficiently include: 1. Operating internal combustion engines and auxiliary  engineroom  machinery. 2. Maintaining internal combustion engines and related accessories and equipment. 3. Performing overhaul and repair work on internal combustion engines, using established procedures  for  disassembly,  replacement,  and reassembly. 4. Conducting routine tests and inspections of all engineroom machinery. 5.  Operating  and  making  repairs  to  auxiliary boilers and to refrigeration, air conditioning, and distilling  systems. 6.  Using  lathes  and  other  machine  shop equipment. 7.  Using  measuring  instruments  needed  in engine  overhaul,  such  as  micrometers,  feeler gages, and inside and outside calipers. 8.  Reading  accurately  such  instruments  as thermometers,   pressure   gages,   and   pressure indicators. Probably you can already do many of these jobs. Others you will have to learn from addi- tional  practical  experience  and  through  study. Although you will be learning many new jobs as an EN1, and especially as a ENC, you will be con- cerned principally with directing and observing the work of personnel assigned to you. You will be responsible for their performance and their training  in  all  of  the  jobs  required  of  an Engineman. In addition to the duties already mentioned, you will compile necessary data for the prepara- tion of engineering reports and records. It will be your  duty  to  make  frequent  tours  of  assigned spaces,  and  to  inspect  equipment  for  proper operation. You will check the auxiliary watch for performance of duty in accordance with standing orders. You will be responsible for the use of the correct  operating  procedure  for  all  equipment under  your  jurisdiction.  You  will  be  accountable for daily routine inspections, tests, and reports on  all  equipment  that  require  daily  maintenance and testing. You may be held responsible to the division officer for the proper setting and standing of all watches during your duty period. You may be required  to  post  the  daily  watch  list  in  the engineroom and may be responsible for instruct- ing and training watchstanders in their duties. You will instruct lower rated personnel in the correct  procedures  to  be  used  for  casualties involving  the  engineroom.  It  will  be  your responsibility to see that personnel under your 1-3
