240 VOLT OPERATION
Your drill press may be converted for 240 volt operation.
The conversion of your drill press for 240 volt operation
must be done by qualified electrical personnel. Should
you desire to have your drill press converted for 240 volt
operation, take your drill press to your local Authorized
Delta Service Center. You can call 800-223-7278 for the
location of the nearest Authorized Service Center.
When converted for 240 volt operation, your drill press is
intended for use on a circuit that has an outlet like the
one illustrated in Fig. 15. After conversion for 240 volts,
the drill press will have a grounding plug that looks like
the plug illustrated in Fig. 15.
Make sure the drill press is connected to an outlet
having the same configuration as the plug. No adapter is
available or should be used when the drill press is
converted for 240 volts. If the drill press must be
reconnected for use on a different type of electrical
circuit, the re-connection should be made by qualified
service personnel; and after re-connection, the tool
should comply with all local codes and ordinances.

EXTENSION CORDS
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 a 3-hole receptacle which will accept the tool’s plug. When using an extension
cord, be sure to use one heavy enough to carry the current of the drill press. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. Fig. 16, shows the correct gauge to use depending on cord
length and voltage. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
