You can have your drill press converted to 230 volt
operation.
A qualified electrician must perform this conversion. Should
you desire to have your drill press converted for 230 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 230 volt operation, your drill press is
intended for use on a circuit that has an outlet like the one
illustrated in Fig. C. After conversion to 230 volts, the drill
press will have a grounding plug that looks like the plug
illustrated in Fig. C.
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 230
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 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.
