Shouldyou desire to have your drill press converted for 240 voltoperation, take your drill press to your local AuthorizedDelta Service Center. You can call 800-223-7278 for thelocation of the nearest Authorized Service Center.When converted for 240 volt operation, your drill press isintended for use on a circuit that has an outlet like theone illustrated in Fig. 15. After conversion for 240 volts,the drill press will have a grounding plug that looks likethe plug illustrated in Fig. 15.Make sure the drill press is connected to an outlethaving the same configuration as the plug. No adapter isavailable or should be used when the drill press isconverted for 240 volts. If the drill press must bereconnected for use on a different type of electricalcircuit, the re-connection should be made by qualifiedservice personnel; and after re-connection, the toolshould comply with all local codes and ordinances.Fig. 16EXTENSION CORDSUse proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord whichhas a 3-prong grounding type plug and a 3-hole receptacle which will accept the tool’s plug. When using an extensioncord, be sure to use one heavy enough to carry the current of the drill press. An undersized cord will cause a drop inline voltage resulting in loss of power and overheating. Fig. 16, shows the correct gauge to use depending on cordlength and voltage. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.MINIMUM GAUGE EXTENSION CORDRECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC TOOLSAmpere Volts Total Length of Gauge ofRating Cord in Feet Extension Cord0-6 120 up to 25 18 AWG0-6 120 25-50 16 AWG0-6 120 50-100 16 AWG0-6 120 100-150 14 AWG6-10 120 up to 25 18 AWG6-10 120 25-50 16 AWG6-10 120 50-100 14 AWG6-10 120 100-150 12 AWG10-12 120 up to 25 16 AWG10-12 120 25-50 16 AWG10-12 120 50-100 14 AWG10-12 120 100-150 12 AWG12-16 120 up to 25 14 AWG12-16 120 25-50 12 AWG12-16 120 GREATER THAN 50 FEET NOT RECOMMENDEDMINIMUM GAUGE EXTENSION CORDRECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC TOOLSAmpere Volts Total Length of Gauge ofRating Cord in Feet Extension Cord0-6 240 up to 50 18 AWG0-6 240 50-100 16 AWG0-6 240 100-200 16 AWG0-6 240 200-300 14 AWG6-10 240 up to 50 18 AWG6-10 240 50-100 16 AWG6-10 240 100-200 14 AWG6-10 240 200-300 12 AWG10-12 240 up to 50 16 AWG10-12 240 50-100 16 AWG10-12 240 100-200 14 AWG10-12 240 200-300 12 AWG12-16 240 up to 50 14 AWG12-16 240 50-100 12 AWG12-16 240 GREATER THAN 100 FEET NOT RECOMMENDED
