Page: 18 / 68

Door Thickness:
The DL-2 is equipped to handle 1
3
/
8
” and 1 ¾” thick doors. If you run 2 ¼” thick
doors, the red hold up wheel bars, and the end rolls need to be adjusted
downwards. All of these brackets have slots for this purpose. To adjust, roll the
door into the machine, and adjust the hold up wheel bars so the door is about

below the bottom of the horizontal steel template supports.
Changing Cutter Speeds:
A triple speed pulley system for wood or metal cutting controls the cutter speeds.
To change the belt speed, remove the top pulley guard, loosen Kip handle to
release tension to change belt.
“
FAST
” speed is wood or fiberglass.
“
MIDDLE
” speed is metal 20-26 gauge.
“
LOW
” speed is metal 16-18 gauge.
Changing or Adjusting Bits:
Turn “OFF” the AIR and ELECTRICAL SUPPLY before working in the cutter
head area. Loosen the collet in the spindle holding either ½” wood or metal bits,
using the wrenches included with the DL-2. Use the
7
/
8
” wrench on the spindle
flats just above the pulley, and the second wrench on the top hex. Unscrew the
draw bar by turning it counterclockwise. After you have given it about three turns,
no more than
1
/
8
” at a time, tap the top hex with a soft faced mallet to break loose
the collet within the taper.
When replacing the bit, insert it into the collet deep enough to ensure your cutting
surface is above and below the door-skin when cutting with the reciprocator
turned on. Once you have determined that it is in the proper distance, tighten the
draw bar in a clockwise direction until the collet is snug in the arbor.
1. Swing the lock bore template into place.
2. With cutter in the up position, place bit into collet loosely.
3. Push cutter head over lock bore template and adjust cutter bit so it
clears the template and reducing ring by

”.
