2.  To  decrease  speed,  loosen  locking  nut  on  speed  adjusting 
screw,  and  turn  screw  in  counterclockwise  direction. 
3.  When  the  speed  is correct,  tighten  the  locking  nut  at  the 
new  setting. 
7-9.3.  Sensitivity  Adjustment.  If  the  governor  is too  sensi- 
tive,  speed  surging  will  occur  with  change  in  load.  If  the 
governor  is not  sensitive  enough,  a big  drop  in  speed  will  oc- 
cur  when  normal  load  is applied. 
I.  To  make  the  governor  more  sensitive,  loosen  the  nut  at 
bottom  of  adjusting  eyebolt  and  tighten  the  top  nut  there- 
by  drawing  the  head  of  the  eyebolt  closer  to  the  governor 
arm  pivot  point. 
2.  To  make  the  governor  less sensitive,  loosen  the  top  nut 
and  tighten  the  bottom  nut  to  move  the  head  of  the  eye- 
bolt  away  from  the  pivot  point. 
3.  After  sensitivity  is  correct,  tighten  the  nut  that  was  pre- 
viously  loosened  to  lock  the  eyebolt  at  the  new  setting.  Re- 
check  speed  after  sensitivity  adjustment  since  changing  this 
will  also  affect  speed.
