Cleaning Press Heads
OPERATION  OF  THE  LAUNDRY PRESS Presses  are  air  operated  and  controlled  by push buttons mounted flush with the front of the press table. The air buttons located on the front of  the  table  are  used  for  lowering,  locking,  and releasing the head. The two outside red buttons lower and lock the head. Both hands must be used to press both buttons at the same time. The release buttons are the two inside green buttons. The head can be released by depressing either the right or left inside release button. Before  you  operate  the  press,  examine  the cover and padding before heating it. Then check the  head  pressure  by  inserting  a  bedding  sheet leaving a portion exposed and trying to pull it out after the press is closed. The bedding sheet will resist all efforts to remove it and remain in place in all areas. If the padding is bad, do not use the press until it  is  repadded.  If  the  cover  is  unsatisfactory, replace it with a new one. When you heat the laundry press, do it grad- ually. Turn the steam valve partially open for 20 minutes and then open it completely. The press is  then  ready  for  use. The time required to press and dry a garment satisfactorily  is  dependent  upon  the  following: 1.  Type  of  material 2.  Moisture  in  the  material 3.  Steam  pressure  (less  than  100  psi  will require  longer  time) 4. Effectiveness of the steam trap in carrying away the condensed steam to allow unrestricted flow  of  live  steam  into  the  head  chamber 5.  Head  pressure An  article  with  a  rough,  dry  appearance usually  requires  more  than  normal  pressing  time. Be  certain,  of  course,  that  the  article  is  damp enough when you start to press it. If the article lacks sufficient moisture for good pressing, spray it with the spray gun. For normal pressing, keep the head down for about 15 seconds. Experience in  pressing  enables  you  to  tell  when  to  add dampness to a garment before you press it, and how long it will take to press that particular type of  material. SAFETY  FEATURES The laundry press head will not close unless you use both hands to push the two red buttons. This  prevents  getting  your  hand  caught  under  the press  head.  Opening  the  press  head  requires pushing  only  one  of  the  green  buttons.  This  is done to allow easy release in an emergency. Also, press  heads  will  not  close  and  lock  if  an  object too thick is between the press head and pad. This safety feature can be tested by taking a bed sheet, rolling it up in a tubular fashion, placing it under the press head, and then trying to close the press head. If the press head is adjusted properly, the head  of  the  press  will  not  lock  shut. Many incidents have occurred where laundry personnel  have  caught  their  hands  between  the press head and the pad. If you follow a few simple safety  precautions,  this  should  never  happen. Never  operate  the  press  if  any  control buttons  are  sticking. Never  plug  one  of  the  buttons  with  any device  to  increase  speed. Do   not   allow   anyone   to   stand   near the press while operating it. Only  one  operator  should  be  working  at a press station at a time.   Know the location of the main steam valve to  the  laundry  in  case  of  an  emergency such as a broken steam line or steam leak. MAINTENANCE  OF  PRESSES The laundry supervisor and operators should not only perform minor maintenance on presses, but also should see that repairs to presses are re- corded properly in the equipment maintenance log. The steam pressure to the presses should be 100 pounds per square inch. Some of the presses have  pressure  gauges.  The  air  pressure  on  air- operated presses should be 75 to 95 pounds per square  inch.  In  addition,  engineering  personnel should give the presses a hydrostatic test once a year.  This  test  should  be  for  150  pounds  per square  inch  for  1  minute. Laundry  personnel  should  not  get  into  the mechanics  of  the  laundry  press;  however,  they should   perform   the   following   operator maintenance: 1.  Thoroughly  clean  presses  (daily). 2. Clean and wax press heads (as required). 3.  Change  pads  and  covers  (as  required). 5-46
