  • Page 19 ADJUSTING THE DRILL SPACING • To slide a drill system one way or the other to reach the required drill spacing, you must first loosen the 5” frame clamps on each end of the feed bar. Loosen all four ½” lock nuts on each frame clamp until you can slide the feed bar.
  • Page 20 ADJUSTING THE DRILL SPACING • To get the proper spacing, measure from one side of the feed bar to the same place on the adjacent feed bar.
  • Page 21 ADJUSTING THE DRILL SPACING • Be sure to measure from both ends of the feed bar to insure the drill systems are parallel to each other. • After moving the proper distance, re-tighten all on the frame clamps. • Heavy load...
  • Page 22 ADJUSTING THE HEIGHT OF THE DRILL SYSTEMS • Adjusting the height of the drill systems is done by turning the mast screw jack assembly located at the top of the mast. Before turning the screw jack, you must first loosen the two ½” x 4” bolts and the two ½”...
