Electrical connections
All electrical connections must be
done by a qualified electrician in compliance with
all local codes and ordinances. Failure to comply
may result in serious injury.
The JD-32120 Drill Presses are rated at 230V power,
The drill press comes with a plug designed for use on
a circuit with a
grounded outlet
.
Before connecting to power source, be sure switch is
in
off
position.
6.1
GROUNDING INSTRUCTIONS
This tool must be grounded. 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
inserted into an appropriate outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Improper connection of the
equipment-grounding conductor can result in a
risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as
to whether the outlet is properly grounded. Do not
modify the plug provided with the tool
– if it will
not fit the outlet, have a proper outlet installed by
a qualified electrician.
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.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord immediately.
6.2
Extension cords
The use of extension cords is discouraged; try to
position machines near the power source. If an
extension cord is necessary, make sure it 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. Table 1 shows correct size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Depth stop adjustment
To drill multiple holes at the same preset depth, use
the depth stop:
1. Make a pencil mark on edge of workpiece to
indicate depth of hole.
2. With drill bit in chuck, lower downfeed handle to
advance bit to your mark.
3. With your other hand, advance lock nuts (A,
Figure 8-1) on the depth stop rod until they are
snug to the seat (B).
The drill bit will now advance to this point.
To release, advance nuts counterclockwise to top of
depth stop.
