POWER CONNECTIONS
A separate 110-120 volt, grounded electrical circuit should be used for your drill press. This circuit should not be less
than #12 wire and should be protected with a 20 amp fuse or circuit breaker. Before connecting the drill press to the
power line, make sure the switch is in the "OFF" position.
If the power cord is worn, cut, or damaged in any way, have it replaced immediately by a certified electrician to avoid
electrical shock or fire hazard.
EXTENSION CORDS
Use proper size 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 to your drill press. An undersized cord
will cause a drop in line voltage resulting in a loss of
power and overheating. Fig. 18, shows the size cord to
use depending on cord length.
If in doubt, use the next heavier gage. The smaller the
gage number, the larger the cord size. Use only 3 wire
extension cords which have 3-prong grounding type
plugs and 3-pole receptacles which will accept the drill
press plug.

GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED
WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
In the event of a malfunction or breakdown, grounding
provides a path of least resistance 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 installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in 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. Use only 3-wire extension cords that have 3-prong grounding
type plugs and 3-hole receptacles that accept the tool's plug, as shown in Fig. 19.
Repair or replace damaged or worn cord immediately.
