Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wireextension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’splug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. Anundersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, shows the correctgauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number,the heavier the cord.EXTENSION CORDS5Fig. DMINIMUM GAUGE EXTENSION CORDRECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC MACHINESAmpere Total Length Gauge ofRating Volts of 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 RECOMMENDEDOPERATING INSTRUCTIONSUNPACKING AND CLEANINGFOREWORDDelta ShopMaster Model DP350 is a 12", variable speed, bench drill press with a flexible work lamp.
