Section IV.  LUBRICATION INSTRUCTIONS 4-8.  General Lubrication  Information. This  section  contains  lubrication  instructions  for the editorial and photomechanical shelter of the special warfare printing plant. 4-9.  Detailed Lubrication  Information. a. General.          Keep     all     lubricants     in     closed containers  and  store  in  a  clean,  dry  place  away  from external   heat.      Allow   no   dust,   dirt,   or   other   foreign material to mix with the lubricants.  Keep all lubrication equipment clean and ready for use. b.    Cleaning.  Keep all external parts not requiring lubrication  clean  of  lubricants.    Before  lubricating  the equipment,  wipe  all  lubrication  points  free  of  dirt  and grease.    Clean  all  lubrication  points  after  lubricating  to prevent accumulation of foreign matter. c. Points   of   Lubrication.      Lubricate   the   door hinges and handles of the editorial and photomechanical shelter   with   a   few   drops   of   OE-10   (Lubricating   Oil, Internal   Combustion   Engine)   monthly,   or   if   binding occurs during operation. d.    Unusual Conditions.  Reduce service intervals i.e.,    lubricate    more    frequently,    to    compensate    for abnormal   or   extreme   conditions,   such   as   high   o   low temperatures,   continued   operation   in   sand   or   dust, immersion in water, or exposure to moisture. Any  one  of  these  operations  or  conditions  may  cause contamination     and     quickly     destroy     the     protective qualities  of  the  lubricants.    Intervals  may  be  extended during   inactive   periods   commensurate   with   adequate preservation. NOTE A   lubricant   which   is   fouled   by dust and sand acts as an abrasive mixture  and  causes  rapid  wear  of parts Section V.  PREVENTIVE MAINTENANCE CHECKS AND SERVICES 4-10.  General. To   ensure   that   the   printing   plant   is   ready   for operation at all times, it must be inspected systematically  so  that  defects  may  be  discovered  and corrected    before    they    result    in    serious    damage    or failure.  The necessary preventive maintenance checks and services are listed in table 4-1.  Defects discovered during operation of the system shall be noted for future correction to be made as soon as operation has ceased. Stop   operation   immediately   if   a   deficiency   is   noted during operation, which would damage the equipment if operation     were     continued.          All     deficiencies     and shortcomings     will     be     recorded     together     with     the corrective  action  taken  on  DA  Form  2404  (Equipment Inspection  and  Maintenance  Worksheet)  at  the  earliest possible opportunity. 4-7
