FOREWORD
Delta ShopMaster DP400 is a 16½" drill press with a 120/240 V, 3/4 H.P. induction motor, a flexible work lamp and a
tilting table with c-clamp edges and diagonal slots. The Delta ShopMaster Model DP400 has a 5/8” capacity chuck and
a 3 3/8” stroke. There are 12 speed options, ranging from 250 rpm to 3000 rpm for optimum drilling performance in a
variety of materials.
FUNCTIONAL DESCRIPTION
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s
plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 or D-2, shows
the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

3. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating between
150 - 250 volts, inclusive:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. C, the
machine will have a grounding plug that looks like the
plug illustrated in Fig. C. Make sure the machine is
connected to an outlet having the same configuration as
the plug. No adapter is available or should be used with
this machine. If the machine must be re-connected for
use on a different type of electric circuit, the re-
connection should be made by qualified service
personnel; and after re-connection, the machine should
comply with all local codes and ordinances.
IN ALL CASES, MAKE CERTAIN THE
