TM  5-3610-286-20 (4) (5) (6) (7) Check  for  loose  electrical  connectors,  damage  to  electrical  conduits  and  sheaths,  and loose  connection  at  electrical  terminals. Inspect for evidence of overheating or arcing in electrical motors. Check for  missing red lock down wing nuts. Inspect  for  rust  on  external  surfaces  and  internal  moving  parts. NOTE If printing press section has been immobile for a long period, check level of TSS press section quarterly (refer to TM 5-3610-287-24). In rainy or soft ground  conditions,  check  monthly. b.    Operational Test.    Perform operational test of the printing press if inspection indicates poor or spotty operator maintenance. Refer to TM 5-3610-286-10 for operator level PMCS. If press does not function normally, PMCS procedures, properly performed, may correct a large percentage of printing press problems. 2-8. Lubrication. Refer to LO 5-3610-286-12 and perform organizational level lubrication as required.  On  printing  presses  equipped  with  “dry”  compressors,  bearings  should  be  lubricated annually  with  grease  at  grease  fitting. 2-9. PMCS Procedures.  Organizational level PMCS is contained in table 2-1. The numbers in the Item No. column show the order in which the check or service should be done. These numbers should be used when recording deficiencies and shortcomings on DA Form 2404, Equipment Inspection and Maintenance  Worksheet.  The l in the interval column indicates when a check or service should be done, as follows: M – Monthly, Q – Quarterly, S – Semiannually, and A – Annually Table  2-1.  Organizational  Preventive  Maintenance  Checks  and  Services  (PMCS). M –  Monthly Q   -   Quarterly S   - Semiannually A   -   Annually Item No. 1 Interval M Q l S l A Item to be inspected Printing  Press Procedures a. b. Visually  inspect  entire  printing  press,  moving in 360 degree circle around the printing press, starting at feed tape table. Check for tamper- ing, damage, or parts missing since last in- spection. Remove the main guard (D/S), and the upper and lower guards (O/S) and inspect for damage and wear of components since last inspection. Also look for signs of rust or corro- sion. Remove feeder pile life chain guard and inspect for damage and wear of components. Check timing adjustment of printing press operations  (para.  2-98). 2-3
