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.
