position  in  front  of  the  body.  Sometimes  the  range pole tip is set on the ground to serve as a pivot. Then the pole may be swayed slowly to the left and/or right until the instrumentman picks up the signal. 5. PLUMB THE ROD. The signal to plumb the rod to the desired direction (right or left) is given by extending the appropriate arm upward and moving the hand in the direction the top of the  rod  must  be  moved  to  make  it  vertical. 6.  ESTABLISH  A  TURNING  POINT.  This signal is given when the instrumentman wants a turning  point  established  during  traversing  or leveling  operations.  It  is  given  by  extending  either arm  upward  and  making  a  circular  motion. 7.   THIS   IS   A   TURNING   POINT.   The rodman  gives  this  signal  to  indicate  a  turning point.  This  is  done  using  a  leveling  rod  and applying  the  method  described  in  4. 8.  WAVE  THE  ROD.  This  signal,  given  by the instrumentman to the rodman, is important to  get  the  lowest  stadia  reading.  The  instru- mentman extends one arm upward, palm of the hand  forward,  and  waves  the  arm  slowly  from side  to  side.  The  rodman  then  moves  the  top  of the  leveling  rod  forward  and  backward  slowly about  a  foot  each  way  from  the  vertical. 9. FACE THE ROD. To give this signal, the instrumentman  extends  both  arms  upward  to indicate  to  the  rodman  that  the  leveling  rod  is facing  in  the  wrong  direction. 10.  REVERSE  THE  ROD.  The  instrument- man gives this signal by holding one arm upward and  the  other  downward,  and  then  reversing  their positions  with  full  sidearm  swings. 11.  BOOST  THE  ROD.  The  instrumentman gives this signal by swinging both arms forward and  upward,  palms  of  the  hands  upward.  This signal is used when the instrumentman wants the leveling rod raised and held with its bottom end at a specified distance, usually about 3 ft, above the  ground. 12.  MOVE  FORWARD.  The  instrumentman gives  this  signal  by  extending  both  arms  out horizontally from the shoulders, palms up, then swinging  the  forearms  upward. 13. MOVE BACK. The instrumentman gives this signal by extending one arm out horizontally from  the  shoulder,  hand  and  forearm  extended vertically,  and  moving  the  hand  and  forearm outward   until   the   whole   arm   is   extended horizontally. 14. UP OR DOWN. The instrumentman gives this signal by extending one arm out horizontally from   the   shoulder   and   moving   it   upward   or downward. This directs the rodman to slide the target  up  or  down  on  the  rod. 15.  PICK  UP  THE  INSTRUMENT.  The party  chief  gives  this  signal  by  imitating  the motions of picking up an instrument and putting in  on  the  shoulder.  The  party  chief  or  other responsible  member  of  the  party  gives  this  signal, directing the instrumentman to move forward to the point that has just been established. 16.  COME  IN.  The  chief  of  party  gives  this signal at the end of the day’s work and at other times, as necessary. Two  additional  hand  signals  are  shown  in figure 12-2. Their meanings are given in the next two  paragraphs. RAISE FOR RED. The instrumentman gives this signal in a leveling operation to ascertain the immediate   whole-foot   mark   after   reading   the tenths  and  hundredths  of  a  foot.  This  usually happens  when  the  rodman  is  near  the  instrument or  if  something  is  in  the  way  and  obscures  the whole-foot   mark. EXTEND  THE  ROD.  The  instrumentman gives this signal when there is a need to extend an adjustable rod. This happens when the height of  the  instrument  becomes  greater  than  the standard length of the unextended adjustable level rod. Figure  12-2.-Additional hand signals. 12-3
