Model T31739 (Mfd. Since 11/19)
The Model T31739 has a depth stop that allows
you to drill repeat non-through holes to the same
depth every time.
The depth stop consists of a stud attached to the
quill with a depth nut that can be lowered or raised
against a stop bracket to control drilling depth.
Figure 29 shows the various components of the
depth stop.

To adjust depth stop:
1. Lower drill bit to required height.
2. Thread depth nut down against stop bracket.
Note:
The scale on the depth stop can be
recalibrated if it gets moved or has changed
from factory setting. Refer to
Calibrating
Depth Stop on Page 32 for instructions on
how this is done.
Any drill bit you install in the chuck must be
tight enough that it will not come loose during
operation. With a keyless chuck like the one that
comes on the T31739, no chuck key is necessary
for tightening or loosening.
Installing/Removing
Drill Bits
Installing a Drill Bit
Removing a Drill Bit
1. DISCONNECT MACHINE FROM POWER!
2. Turn drill chuck counterclockwise on arbor to
open jaws enough to accept shank of drill bit.
3. Insert drill bit as far as possible into chuck
WITHOUT allowing chuck jaws to touch
fluted portion of bit, and hand-tighten chuck
clockwise as tightly as you can.
Note: Make sure small bits are not trapped
between edges of two jaws; if they are, rein-
stall drill bit or it will not be secure enough to
use for drilling.
1. DISCONNECT MACHINE FROM POWER!
2. Turn chuck counterclockwise to open jaws
and catch drill bit with a rag to protect hands.
