2. Feed Depth Adjustment
    The depth gauge is located on the feed handle hub. Use the depth
    gauge to accurately and consistently set the required drilling depth.
    Loosen the depth stop fixing screw, set the depth stop as required and
    subsequently re-tighten the fixing screw.
3. Speed Adjustment
     This drill press has 12 speeds shown in the speed label located on the un- 
     derside of the head assembly lid. To change the speed, loosen the belt   
     tension lock knob on each side of the head. Then use the adjustment lever    
     to draw the motor mounting plate toward the front end of the drill head.  
     Next, change the belt locations on the pulleys.
     Tighten the belts by pushing the adjustment lever towards the rear of the   
     drill head and locking the belt tension knobs.
 
See Fig.13 and Fig.13A
4. Spindle Spring Adjustment
     The spindle return spring may need adjustment if the tension causes the   
     spindle to return too rapidly or too slowly.
 
4.1 Lower the table for additional clearance
.
4.2 Place a screwdriver in the lower front notch (1) of the spring cap (2).                 
      Hold it in place while loosening and removing only the outer lock nut (3).
4.3 With the screwdriver still engaged in the notch loosen the inner
      nut (4) just until the notch (5) disengages from the boss (6) on the drill  
      press head
.
CAUTION: DO NOT REMOVE THIS INNER NUT, because the spring will 
forcibly unwind.
4.4 Carefully turn the spring cap (2) counterclockwise with the screwdriver,  
      engaging the next notch.
4.5 Lower the spindle to the lowest position by rotating the feed handle in a  
      counterclockwise direction while holding the spring cap (2) in position.
4.6 If the spindle moves up and down as easily as you desire, tighten the 
      inner nut (4) with the adjustable wrench. If too loose, repeat steps 2    
      through 4 to tighten. If too tight, reverse steps 3 and 4.
 DO NOT OVER-   
      TIGHTEN and restrict spindle movement.
4.7 Replace the lock nut (3) and tighten against the inner nut (4) to prevent  
      the inner nut from reversing. 
See Fig.14 and Fig. 14A
5. SPINDLE
    Rotate the feed handles counterclockwise to lower spindle to its lowest 
    position. Grasp the spindle and attempt to move it back and forth. If there is    
    play, do the following:
    5.1  Loosen the spring cap lock nut (1).
    5.2  Turn the screw (2) clockwise to eliminate the play, but without 
           obstructing the upward movement of the spindle.
    5.3  Tighten the lock nut (1). 
See Fig. 15
