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.

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.

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. BA 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.
