GROUNDING INSTRUCTIONS

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric
current and reduces the risk of shock. This tool is
equipped with an electric cord that has an equipment
grounding conductor and grounding plug. The plug MUST
be plugged into a matching receptacle 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
receptacle, have the proper receptacle installed by a
qualified electrician.
IMPROPER CONNECTION of the equipment grounding
conductor can result in risk of electric shock. The
conductor with the green insulation (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
you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.
USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE 3-
PRONG GROUNDING PLUGS AND 3-POLE RECEPTACLE
THAT ACCEPT THE TOOL'S PLUG. REPAIR OR REPLACE
DAMAGED OR WORN CORD IMMEDIATELY.
GUIDELINES FOR EXTENSION CORDS
Make sure your extension cord is in good condition. When
using an extension cord, be sure to use one heavy enough
to carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating. The table below shows the
correct size to use according to cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
Be sure your extension cord is properly wired and in good
condition. Always replace a damaged extension cord or
have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit
must not be less than #12 wire and should be protected
with a 15 Amp time lag fuse. Before connecting the motor
to the power line, make sure the switch is in the OFF
position and the electric current is rated the same as the
current stamped on the motor nameplate. Running at a
lower voltage will damage the motor.
This tool is intended for use on a circuit that has a
receptacle like the one illustrated in FIGURE A.

FIGURE A shows a 3-prong electrical plug and receptacle
that has a grounding conductor. If a properly grounded
receptacle is not available, an adapter (FIGURE B) can be
used to temporarily connect this plug to a 2-contact
ungrounded receptacle. The adapter (FIGURE B) has a
rigid lug extending from it that MUST be connected to a
permanent earth ground, such as a properly grounded
receptacle box. THE TEMPORARY ADAPTER SHOULD BE
USED ONLY UNTIL A PROPER GROUNDED OUTLET CAN
BE INSTALLED BY A QUALIFIED ELECTRICIAN. The
Canadian Electrical Code prohibits the use of adapters.
CAUTION: In all cases, make certain the receptacle in
question is properly grounded. If you are not sure have a
certified electrician check the receptacle.
WARNING
This drill press is for indoor use only. Do not expose to
rain or use in damp locations.
