Important Safety Information

Most  accidents    tha t involve  produc  t  op eration,  ma intena nc e and   repair   are  caus  ed  by  failure  to

ob serve  basic   safety   rules  or  precautions  .  An accident    can   often  be  avoided   by  recog nizing  pote ntially

ha za rdous  situations   before   an  accident    oc curs . A person    mus t be  alert   to pote ntial  ha za rds.  This

person   should   also  ha ve  the  ne cessary   training,  skills  and   tools  to perform   the se  func tions properly.

warnings in this publication and on the product are, therefore, not all inclusive. If a tool, procedure,

work method or operating technique that is not specifically recommended by Perkins is used,

you must satisfy yourself that it is safe  for you and for others. You should also ensure that the

product will not be damaged or be  made unsafe by the operation, lubrication, maintenance or

repair procedures that you choose.

The  informa tion, specifications   ,  and  illustrations   in  this  pub lication  are   on the  basis    of informa tion tha t

was  available    at  the  time  tha t the  pub lication   was  written.   The  specifications   , torque  s,  pressure  s,

me asure me nts , adjustme  nts , illustrations ,  and  othe r  items  can  cha  ng e at  any  time.  These  cha ng es  can

affect   the  service   tha t is given   to the  produc  t.  Ob tain the  comp  lete  and  mos t current   informa tion before
