Functional Description, Extension Cords, Foreword

2.Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than

150 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 machine will have a grounding plug that looks like the plug illustrated in Fig. B. A temporary adapter, which looks like the adapter illustrated in Fig. C may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. C, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. Whenever the adapter is used, it must be held 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 you are not sure, have a qualified electrician check the receptacle.

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 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.

FUNCTIONAL DESCRIPTION

FOREWORD

Delta 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 an integrated quill stop. The 18-900L has a tilting table for angle drilling. Side edges and parallel slots are provided for fast workpiece clamping. The laser helps users target the workpiece exactly where the drill bit will enter the material.
