CHICAGO 60648 1175/262 2 ATTENTION:      READ   CAREFULLY   AND   REFER   TO   OPERATING   MANUAL   &   SERVICE   GUIDE,   FORM   5S1408,   BEFORE ATTEMPTING  TO  INSTALL,  OPERATE  OR  SERVICE  YOUR  SPEEDAIRE  COMPRESSOR  HEAD  AIR  PUMP).    FAILURE  TO COMPLY   WITH   INSTRUCTIONS   COULD   RESULT   IN   PERSONAL   INJURY   AND/OR   PROPERTY   DAMAGE!      RETAIN   FOR FUTURE REFERENCE. Description Your Speedaire Compressor Head (air pump) is a two-stage, heavy-duty,   industrial   unit.      Each   unit   is   equipped   with  a centrifugal   unloader   for   loadless   starting,   counter-balanced, ductile,  Iron  crankshaft,  Timken  tapered  roller  bearings  and Die-cast   aluminum   cylinders.      The   Compressor   Head   also features   Swedish   steel   disc-type   valves,   finned   intercooler, splash lubrication system, visual oil-level gauge and balanced, fan-type flywheel (rotates CCW facing flywheel). MODEL          3Z182B     utilizes     pressure     switch     control     for intermittent duty applications (start-stop operations). MODEL  3Z183B  uses  constant  speed  control  for  continuous duty applications. For   additional   information   on   the   Compressor   Head,   see Specification and Performance Charts. Figure 1 - Compressor Head (Air Pump) General Safety Information Because the Compressor Head (Air Pump) is an integral part of the air compressor system, the following safety precautions should be observed at all times: 1. Read   the  instruction   manuals   for   each   component carefully before attempting to assemble, disassemble or operate your particular system. 2. Do not exceed the pressure rating of any component in the system. 3. Protect   material   lines   and   air   lines   from   damage   or puncture. 4. Never point a spray gun at oneself or any other person. Accidental discharge may result in serious injury. 5. Check  hoses  for  weak  or  worn  condition  before  each use, making certain that all connections are secure. 6. Release    all    pressures    within     the     system     before attempting to service any component. 7. Follow  all  local  electrical  and  safety  codes,  as  well  as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA). 8. On engine driven units, check engine oil and fuel levels before  starting.    DO  NOT  ADD  GASOLINE  TO  A  HOT ENGINE! 9. Electric    motors    must    be    securely    and    adequately grounded.  This can be accomplished by wiring with a grounded,   metal-clad   raceway   system,   by   using   a separate ground wire connected to the bare metal of the motor frame, or other suitable means. 10. Always disconnect power source before working on or near   a   motor   or   its   connected   load.      If   the   power disconnect   point   is   out-of-sight,   lock   it   in   the   open position  and  tag  to  prevent  unexpected  application  of power. 11. All moving parts should be guarded. 12. Be  careful  when  touching  the  exterior  of  an  operating motor  -  it  may  be  hot  enough  to  be  painful  or  cause injury.    With  modern  motors  this  condition  is  normal  if operated at rated load and voltage - modern motors are built to operate at higher temperatures. 13. Protect  the  power  cable  from  coming  in  contact  with sharp objects. 14. Do  not  kink  power  cable  and  never  allow  the  cable  to come   in   contact   with   oil,   grease,   hot   surfaces,   or chemicals. 15. Make  certain  that  the  power  source  conforms  to  the requirements of your equipment. 16. When    cleaning    electrical    or    electronic    equipment, always  use  an  approved  cleaning  agent  such  as  dry cleaning solvent. 17. Wiping  or  cleaning  rags  and  other,   flammable   waste materials   must   be   placed   in   a   tightly   closed   metal container and disposed of later in the proper fashion. -1-
