FORM 5S1138 MODEL 2Z853C 08942 Operation IMPORTANT:      FOR   MAXIMUM   EFFICIENCY.      THIS AIR-WRENCH  SHOULD  BE  OPERATED  WITH  90  PSI OF CLEAN, DRY AIR WHILE RUNNING FREE. CAUTION:  Never use higher air pressure to increase the   output   of   the   Air-Wrench.      Overloading   will drastically  shorten  the  life  of  all  Internal  parts.    DO NOT  use  hand  sockets!!  Use  Only  Impact  wrench sockets. WARNING:  ALWAYS  USE  EYE  PROTECTION  WHEN OPERATING THIS TOOL. Before  each  shift,  drain  water  out  of  air  tank  and  blow condensation   from   air   lines.      Blow   down   compressor more frequently in hot, humid weather.  After clearing air compressor of moisture and lubricating wrench, connect to  a  proper  size  air  hose  and  select  a  socket  which  fits tool shank and nut closely. Loose,  worn  or  cracked  sockets  reduce  impact  power. Where   possible,   use   deep   sockets   in   place   of   long, springy  extension  bars  which  absorb  impact.    Always use  the  simplest  hook-up  possible,  as  each  connection reduces available power. To   set   Air-Wrench   to   desired   power,   select   a   nut   or screw of known tightness of the same size, thread pitch and  thread  condition  as  those  on  the  job.    Turn  power regulator   to   low   position,   apply   wrench   to   nut   and gradually  increase  power  (turn  regulator  to  admit  more air)   until   nut   moves   slightly   In   the   direction   it   was originally  set.    The  wrench  is  now  set  to  duplicate  that tightness,  note  regulator  setting  for  future  use.    When tightening  nuts  not  requiring  critical  torque  values,  run nut up flush and then tighten an additional one quarter to one   half   turn   (slight   additional   turning   is   necessary   if gaskets   are   being   clamped).      For   additional   power needed  on  disassembly  work,  turn  regulator  to  Its  fully open position.  This Air-Wrench is rated at 112" USS bolt size.  Rating must be down graded for spring U bolts, tie bolts,  long  cap  screws,  double  depth  nuts,  badly  rusted conditions  and  spring  fasteners  as  they  absorb  much  of the  impact  power.    When  possible,  clamp  or  wedge  the bolt to prevent springback. Soak  rusted  nuts  in  penetrating  oil  and  break  rust  seal before running off with Air-Wrench.  If nut does not start to  move  in  three  to  five  seconds,  use  a  larger  size  Air- Wrench.    Do  not  use  Air-Wrench  beyond  rated  capacity as this will drastically reduce tool life. Installation An  air  compressor  of  at  least  one  horsepower  with  four CFM  delivery  at  100  psi,  with  an  air  tank  of  at  least  40 gallons capacity is required. Pipe   and   fittings   between   compressor   and   air   hose should be at least 1/2” nominal size (5/8” l.D.).  Be sure piping is free of dips or sags where moisture can collect. Air hose should be at least 3/8” I.D.  When two or more lengths  of  hose  are  connected  together,  all  except  the short leader hose should be 1/2” I.D. Couplers may be used.  Do not connect couplers directly to the air inlet.  They increase the overall bulk of the tool, put  an  unnecessary  strain  on  the  tool  inlet  threads  and deteriorate rapidly due to vibration. The    use    of    air    filters    and    air    line    lubricators    is recommended.    Clean  air  strainer  frequently  to  remove accumulations  of  foreign  matter  which  restrict  air  flow. Never omit strainer from the Air-Wrench. Trouble Shooting Factors   outside   the   tool   may   cause   loss   of   power   or erratic  action.    Reduced  compressor  output,  excessive drain  on  the  air  line,  moisture  or  restrictions  in  air  pipes or the use of hose connections of improper size or poor condition may reduce air supply.  Grit t gum deposits in the   tool   may   cut   power   and   may   be   corrected   by cleaning  the  air  strainer  and  flushing  out  the  tool  with gum  solvent  oil  or  an  equal  mixture  of  SAE  #10  oil  and kerosene.    The  use  of  worn  or  cracked  sockets  may prevent   the   wrench   from   delivering   full   power   to   the work.    If  outside  conditions  are  in  order,  disassemble tool,  replace  worn  or  damaged  parts,  clean,  reassemble and relubricate.
