  4. 4. INTRODUCTION Pakistan Ordinance Factories are the premierdefense industries in Pakistan producing a widerange of conventional defensive ammunitions tointernational standards. Recognized for quality, reliability and competitivePOF products are internationally accepted.4
  5. 5. INTRODUCTION The nucleus of POF has grown in to a largemodern engineering and chemical group offactories, producing large range of munitionssystems of ground, air and naval forces inadditions to meeting the domestic demands of thedefense forces5
  6. 6. INTRODUCTION POF products are in service with over 30 countries,conforming to the highest international standards ofquality and reliability. An international name in quality and reliability, allmanufacturing units of POF are ISO-9001 & ISO-14001certifies. Its metallurgical testing labs and ballisticproof ranges have the word’s class recognition of ISO-17025.6
  7. 7. MAINTENANCE OF MACHINES In the field of maintenance the traditionalapproach has been to rely upon the knowledge andskill of the craft-persons who conduct it. There is agreat deal of pride of workmanship and, in all toomany organizations, a great deal of psychic incomein addition to significant overtime pay forsuccessful emergency repairs to return equipmentto operation after unplanned shutdown.7
  8. 8. Machine Breakdowns Main reasons of machine breakdowns are asfollows: Lack of or Improper Maintenance (Cleaning &lubrication oil checks) Age of Equipment - Exhausted Useful Life ofMachinery Improper Use of Equipment Lack of Control or Safety Devices8
  9. 9. Machine Breakdowns Failure of Safety Devices to Function Properly Poor Workmanship/Inferior Materials (e.g.; Castiron) Operator Error Poor Operating Environment External Forces9
