SETTING UP Your     17"     Variable     Speed     Drill     Press     was     completely assembled  and  tested  at  the  factory.    When  selecting  floor space please note that vibration transmitted through inadequately constructed floors by adjacent machinery or other source  can  impair  the  accuracy  of  your  machine.    Supplied with your drill are four anti-vibration pads and four steel plates. When   the   drill   is   moved   to   it's   permanent   shop   location, position  the  four  anti-vibration  pads  and  the  four  1/16"  steel plates under each corner of the drill press base, with the steel plates  between  the  pads  and  the  base  of  the  drill.    If  the machine is to be fastened to the floor, the compressed height to the top of the steel plates should be 5/16". The head ad table of your drill press have been lowered on the column  for  convenience  in  packaging.    To  raise  the  head, proceed as follows: 1. Place  a  block  of  wood,  about  7"  long.    between  the  drill press head and the table, as close to the column as possible. 2. Make    sure    the    collar    at    the    bottom    of    the    raising mechanism  rack  is  tight  on  the  column  and  unlock  the  table clamp.  Then loosen the two bolts, located on the right hand side of the head, that lock the head to the column. 3. Turn the raising mechanism hand crank clockwise to raise the table and head simultaneously. 4. When    the    table    approaches    the    top    of    the    raising mechanism,  lock  the  table  and  head  to  the  column.    Then loosen   the   raising   mechanism   collar   and   turn   the   raising mechanism hand crank counter-clockwise.  This will slide the rack of the raising mechanism further up the column. 5. Repeat  STEPS 2, 3 and 4 until the top of the head is at the  desired  height.    Be  sure  not  to  raise  the  top  of  the  head casting beyond the top end of the column. 6. With  the  head  and  table  still  loose,  visually  line  up  the spindle   with   center   of   the   base   and   lock   the   head   to   the column. 7. Position  the  table  and  raising  mechanism  to  the  desired position on the column and lock them in place. The table and all other machined or unpainted surfaces of the drill press are protected with a coating of rust preventive.  This coating   may   be   removed   with   a   soft   cloth   moistened   with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose.) After cleaning, cover all unpainted surfaces with a light film of good machine oil. MOTORS AND SPEEDS Rockwell ³/4 hp or 1 hp 8¹/2" frame motors may be used on 17" Drill Presses.  However, ³/4 hp motors should not be used for any  power  feed  or  variable  speed  machines  when  they  are intended for full capacities. With a 1140 rpm motor, spindle speeds between 230 and 2830 rpm can be obtained. With a 1725 rpm motor, spindle speeds between 350 to 4250 rpm can be obtained When selecting a motor of any other make, be certain that it has the above specifications and is a NEMA 182 frame motor. Also  be  sure  it  is  protected  against  loss  of  lubricant  when operated in a vertical position. When assembled to the drill press, the motor should turn in a clockwise direction as viewed from the top. ADJUSTING SPINDLE RETURN SPRING For the purpose of automatically returning the spindle upward after a hole has been drilled, a spring is provided enclosed in the case (A) Fig. 1, and is located on the left side of the drill press  head.    This  spring  has  been  properly  adjusted  at  the factory  and  this  adjustment  should  not  be  disturbed  unless absolutely necessary. If it should become necessary to adjust it, proceed as follows: 1. Back off the two nuts (B) Fig.  1.  NOTE: Do not remove the inside nut from the shaft.  The nuts (B) should be backed off  just  far  enough  so  that  the  spring  housing  (A)  can  be disengaged from the roll pin in the head casting. 2. With   a   firm      hold   on   the   spring   housing   (A)   Fig.   1, disengage it from the pin in the drill press head, by pulling the housing straight out, and turn the housing counterclockwise to increase  or  clockwise  to  decrease  tension.    CAUTION:  BE CAREFUL NOT TO BOTTOM THE RETURN SPRING WHILE TURNING  THE  HOUSING  COUNTERCLOCKWISE.    THERE SHOULD  BE  ENOUGH  SLACK  LEFT  IN  THE  SPRING  TO PERMIT LOWERING THE SPINDLE THE FULL AMOUNT OF TRAVEL.  Be sure the pin in the drill press head is engaged with the spring housing before releasing grip. 3. Retighten  the  two  nuts  (B)  Fig.  1.  NOTE:  Do  not  over- tighten  the  inside  nut  against  the  spring  housing  (A)  as  this may cause binding of the pinion shaft. 4. The  tension  of  the  spring  can  be  tested  by  turning  pilot wheel  counterclockwise.    Be  sure  quill  is  not  locked  while testing. NOTE: The spindle return spring will lift approximately 40 pounds.  When tapping heads, multiple spindles, or other heavy  tooling  is  mounted  on  the  quill  or  spindle  of  your machine, the use of our Cat.  No.  17-838 Booster Spindle Return  Spring  Kit,  along  with  the  return  spring  supplied with   your   drill   press,   will   enable   the   spindle   to   lift approximately 80 pounds.
