6EXTENSION CORDSUse proper extension cords. Make sure yourextension cord is in good condition and is a 3-wire extensioncord which has a 3-prong grounding type plug and matchingreceptacle which will accept the machine’s plug. When usingan extension cord, be sure to use one heavy enough to carrythe current of the machine. An undersized cord will cause adrop in line voltage, resulting in loss of power and overheating.Fig. D-1 shows the correct gauge to use depending on thecord length. If in doubt, use the next heavier gauge. Thesmaller the gauge number, the heavier the cord.Fig. D-1MINIMUM 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 RECOMMENDEDFOREWORDDelta Model 18-900L 18" (457 mm) Drill Press With Lasers is a heavy-duty machine with a 3/4 HP, 120V induction motor,5/8" capacity chuck and key, cast iron table, rack and pinion elevation mechanism, an external depth stop and anintegrated quill stop.

Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than150 volts:If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. B, the machinewill have a grounding plug that looks like the plug illustrated in Fig. B. A temporary adapter, which looks like the adapterillustrated in Fig. C may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. C, if aproperly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outletcan be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter mustbe connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must beheld in place with a metal screw.NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric Code.SHOCK HAZARD. In all cases, make certain that the receptacle in question is properly grounded. If youare not sure, have a qualified electrician check the receptacle.
