Special Tools and Equipment There    are    no    special    tools    or    equipment required  to  perform  operator  maintenance  on  the  jaw crusher. 27. Basic Issue Item Tools and Equipment The    basic    issue    item    tools    and    equipment authorized  for  or  initially  supplied  with  the  jaw  crusher are listed in Appendix II. Section II.  LUBRICATION 28. General Lubrication Information a. This section contains general lubrication instructions,   and   supplemental   lubrication   instructions which   are   not   specifically   covered   in   the   lubrication order. b. Refer     to     LO     5-3820-205-12-2     for     specific lubrication instructions. 29. Detailed Lubrication Information a. Care  of  Lubricants.    When  storing  or  handling lubricants,   ensure   that   the   containers   are   clean   and securely  covered  to  prevent  dirt,  dust,  or  other  foreign matter from entering.  Ensure that the lubricant is clean before using it. b. Cleaning.    Clean  all  surfaces  surrounding  the point to be lubricated before applying the lubricant.  Use a clean cloth dampened in an approved cleaning solvent to   clean   the   surface   before   lubricating.      Remove   all excess lubricant after lubrication. c. Points of Application.  The points of application can be located by referring to LO 5-3820-205-12-2. Caution Over-lubrication may cause equipment     failure     or     damage     to working parts. d. Special    Lubrication    Instructions    for    Unusual Conditions.    Lubrication  intervals  will  be  more  frequent when operating the jaw crusher during extremely high or low temperature, in dust or sand, or under any condition which    tends    to    destroy    the    protective    quality    and quantity of the lubricant. e. Crankcase   Breather.      Service   the   crankcase breather (fig.  39). f. Engine    Oil.        When    using    OEA    oil    in    the crankcase, observe the following precautions: (1) The  crankcase  oil  level  must  be  checked frequently as oil consumption may increase. (2) The    oil    may    require    changing     more frequently than usual because contamination    by    dilution    and    sludge formation will increase under cold weather operating conditions.
