Adjusting the Depth Stop for Tapping
(JDP-20VS-3 only)
To adjust the depth stop for tapping, follow the
instructions for adjusting the depth stop for drilling.
The major differences in the tap mode are two
micro-switches. One micro-switch automatically
reverses (counter-clockwise) the spindle direction at
a predetermined depth. The other micro-switch
forwards (clockwise) the direction of the spindle
once it is fully retracted.
Spindle Preparation
Thoroughly clean the inside of the spindle with a soft
dry cloth. Also clean any taper or arbor to be used
in the spindle. If these are not kept clean, the taper
or arbor will not "seat" properly in the spindle and
may drop out unexpectedly.
Installing Drill Chuck Arbors or Taper Drill
Bits
1: Disconnect the machine from the power source.
2. Make sure the spindle bore and the arbor or drill
bit is clean.
3. Place a protective piece of scrap wood on the
table.
4. Raise the table to approximately 8" to 10" below
the spindle.
5. Insert the Morse Taper 3 taper bit or chuck arbor
into the spindle. If the taper bit or chuck arbor
has a tang, turn the bit or arbor until the tang
engages the slot inside the spindle.
6. Lower the spindle with the handle assembly and
seat the taper bit or chuck arbor with pressure
on the handle assembly.

loosens and falls out
