These general maintenance instructions contain general shop practices and specific methods you must be familiar with to properly   maintain   the   6KVRRTFL.      You   should   read   and   understand   these   practices   and   methods   before   starting maintenance tasks on the 6KVRRTFL. 2-8 WORK SAFETY. a. Before  starting  a  task,  think  about  the  risks  and  hazards  to  your  safety  as  well  as  others.    Wear  protective equipment such as safety goggles or lenses, safety shoes, rubber apron or gloves.  Protect yourself against injury. b. When  lifting  heavy  parts,  have  someone  help  you.    Ensure  that  lifting  equipment  is  working  properly,  that  it  is suitable for the task assigned, and is secured against slipping. c. Always use power tools carefully. 2-9. GENERAL INFORMATION. a. Before beginning a task, find out how much repair, modification, or replacement is needed to fix the equipment as described  in  this  manual.  Sometimes  the  reason  for  equipment  failure  can  be  seen  right  away  and  complete teardown is not necessary to repair or replace damaged or broken parts. b. All  tags  and  forms  attached  to  the  equipment  must  be  checked  to  learn  the  reason  for  removal  from  service. Check all Modification Work Orders (MWO) and Technical Bulletins (TB) for equipment changes or broken parts. c. In some cases a part may be damaged by removal.  If the part appears to be good, and other parts behind it are not defective, leave it on and continue the procedure.  Here are a few simple rules: (1) Do not take out dowel pins or studs unless loose, bent, broken or otherwise damaged. (2) Do not pull bearings or bushings unless damaged.  If you must get at parts behind them, pull out bearings or bushings carefully. (3) Replace all gaskets, seals, and preformed packings. 2-17
