EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong ground-
ing plugs and 3-pole receptacles that accept the tool's plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.
Length of Extension Cord Wire Size (A.W.G.)
Up to 25 feet 14
26-50 feet 14
When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the let-
ters WA on the cord's jacket.
Before using an extension cord, inspect it for loose or ex-
posed wires and cut or worn insulation.
CAUTION:
Keep the cord away from the cutting area and
position the cord so that it will not be caught on
material, tools, or other objects during cutting.
ELECTRICAL CONNECTION
Your drill press is powered by a precision built electric mo-
tor. It should be connected to a power supply that is 120
volts, 60 Hz, AC only (normal household current). Do not
operate this tool on direct current (DC). A substantial voltage
drop will cause a loss of power and the motor will overheat.
If the machine does not operate when plugged into an outlet,
double check the power supply.
POWER SUPPLY
Before operating your drill press, check your power sup-
ply and make sure it meets the requirements listed on the
tool’s data plate. A substantial voltage drop will cause a
loss of power and machine overheating.
Common causes of power loss and machine overheat-
ing are insufficient extension cord size and multiple tools
operating from the same power source.
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding pro-
vides a path of least resistance for electric current to reduce
the risk of electric shock. This tool is equipped with an elec-
tric cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have
the proper outlet installed by a qualified electrician. Improper
connection of the equipment-grounding conductor can result
in a risk of electric shock. The conductor with insulation having
an outer surface that is green with or without yellow stripes is
the equipment-grounding conductor. If repair or replacement
of the electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet
like the one shown in Figure 1. It also has a grounding pin
like the one shown.
