Grounding Instructions This tool must be grounded while in use to
protect the operator from electric shock.
In the event of a malfunctio n or breakdown,
grounding provides a path of least resista nce for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric 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 insta lled by a
qualified elect rician.
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 equip ment-
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 gro unded. Use only
three wire extension cords that have three-prong
grounding plugs and three-pole receptacles that
accept the tool’s plug.
Repair or replace a damaged or worn cord
immediately.
Extension Cords Make sure your extension cord is in good
condit ion. When using an e xtension c ord, be
sure to use one heavy enough to carry the
current your machine will draw. An undersized
cord will caus e a drop in t he line voltag e
resulting in power loss and overheating. T he
following table shows the correct size to use
depending on the cord length a nd nameplate
ampere rating. If in doubt, use the next heavier
gauge. Remember, the smaller the gauge
number, the heavier the cord.

The drill press with a 230-volt p lug should only
be connected to an outlet having the same
configuration (D, Fig. 17). No adapter is
available or should be used with the 230-volt
plug.
Important: In all cases (115 or 230 volts), make
certain the receptacle in questio n is properly
grounded. If you are not sure, have a registered
electrician check the receptacle.
