SECTION B - OPERATION General 1. The  CM  Lodestar  Protector  is  designed  to  allow  the intermediate  gear  to  slip  on  an  excessive  overload. An overload is indicated when the hoist will not raise the load.  Also, some clutching noise may be heard if the  hoist  is  loaded  beyond  rated  capacity.    Should this  occur,  immediately  release  the  up  (i)  control  to stop the operation of the hoist.  At this point, the load should be reduced to the rated hoist capacity or the hoist   should   be   replaced   with   one   of   the   proper capacity.      When   the   excessive   load   is   removed, normal hoist operation is automatically restored. CAUTION:      The   CM   Lodestar   Protector   is   susceptible   to overheating   and   wear   when   slipped   for   extended   periods. Under no circumstance should the clutch be allowed to slip for more than a few seconds. Due   to   the   above,   the   Lodestar   Hoist   equipped   with   a Protector   is   not   recommended   for   use   in   any   application where there is a possibility of adding to an already suspended load to the point of overload. This includes dumbwaiter ( *) installation, containers that are loaded in mid-air, etc. Also,  if  a  Lodestar  Hoist  with  a  Protector  is  used  at  unusual extremes  of  ambient  temperatures,  above  150'  F.    or  below 15' F., changes in lubricant properties may permit the hoist to raise larger loads than under normal operating conditions and presents possibility of damage or injury. 2. All hoists are equipped with an adjustable screw limit switch,  which  automatically  stops  the  hook  at  any predetermined point when either hoisting or lowering. 3. The control station used on two speed hoist is similar to single speed unit, except that either of two definite speeds   may   be   selected   by   the   operator   in   both hoisting  and  lowering.    Each  control  when  partially depressed   provides   SLOW   speed   and   when   fully depressed   gives   FAST   speed.      Partial   release   of control  returns  hoist  to  slow  speed,  while  complete release allows hoist to stop.  Rated lifting speeds are shown on hoist identification plate. SLOW  speed  is  intended  as  a  means  of  carefully controlling  or  "spotting"  the  load,  although  the  hoist may be operated solely at this speed if desired.  It is not necessary to operate in the SLOW speed position as  the  hoist  will  pick  up  a  capacity  load  at  FAST speed from a standing start.  In other words, it is not necessary   to   hesitate   at   the   slow   position   when moving control from STOP and FAST position or vice versa. 4. If material being handled must be immersed in water, pickling baths, any liquid, dusty or loose solids, use a sling   chain   of   ample   length   so   that   the   hook   is always   above   the   surface.      Bearings   in   the   hook block are shielded only against ordinary atmospheric conditions. Refer to limitations on inside cover sheet coning dumbwaiter applications. Operating Instructions HOIST 1. Before picking up a load, check to see that the hoist is directly overhead. 2. WHEN    APPLYING    A    LOAD,    IT    SHOULD    BE DIRECTLY  UNDER  HOIST  OR  TROLLEY.    AVOID OFF CENTER LOADING OF ANY KIND. 3. Take  up  a  slack  load  chain  carefully  and  start  load easily to avoid shock and jerking of hoist load chain. If  there  is  any  evidence  of  overloading  immediately lower the load and remove the excess load. 4. Do not allow the load to swing or twist while hoisting. HOIST WITH LOW HEADROOM TROLLEY This   unit   should   be   moved   by   pushing   on   the suspended   load   or   by   pulling   the   empty   hook. However,  the  unit  can  also  be  moved  by  pulling  on the   control   station   since   an   internal   steel   cable extends    the    length    of    the    control    cord    and    is anchored to the hoist and to the control station. HOIST WITH MOTOR DRIVEN TROLLEY This unit should be moved by operating the controls marked * (FORWARD) and $ (REVERSE) in control station.  Unless altered by the erector, depressing 4 (FORWARD)   control   will   move   the   hoist   toward motor  housing  end.    Anticipate  the  stopping  point and    allow    trolley    to    coast    to    a    smooth    stop. Reversing    or    "plugging"    to    stop    trolley    causes overheating of motor and swaying of load. Safety Procedures 1. When   preparing   to   lift   a   load,   be   sure   that   the attachments  to  the  hook  are  firmly  seated  in  hook saddle.      Avoid   off   center   loading   of   any   kind, especially loading on the point of hook. 2. When lifting, raise the load only enough to clear the floor   or   support   and   check   to   be   sure   that   the attachments to the hook and load are firmly seated. Continue  lift  only  after  you  are  assured  the  load  is free of all obstructions. 3. Do  not  load  hoist  beyond  the  rated  capacity  shown on  hoist  identification  plate  or  on  the  hoist  motor housing cover, Models A thru H and A-2 thru H-2 and on hoist back frame cover, Models J thru RR and J-2 thru RR-2.  Overload can cause immediate failure of some  load  carrying  part  or  create  a  defect  causing subsequent 11
