Figure 13
Work Light (J-2500 and J-2530 only)
Install a light bulb, no larger than 60 watts into the
socket accessed from beneath the head. The rocker
switch controls the light switch (D, Fig. 13).
11
Table Tilt A djustmen t
Positioning the Workpiece
The table tilt adjustments are made on the table
bracket under the table.
To tilt the table (refer to Figures 14 and 15):
In the following steps do not over loosen. This
could result in the table assembly to separate
from the column, fall and cause injury.
1. Loosen the socket head set screw (A) with a
3mm hex wrench.
2. Using a 15/16" wrench, loosen the hex cap
screw (B), and tilt the table to the desired angle
by aligning the arrow (C, Fig. 15) on the rotating
part of the bracket to the desired angle (in
degrees) displayed on the scale (D, Fig 15) at
the base of the bracket.
3. Tighten the hex cap screw (B).
4. Tighten the socket head set screw (A).
Always place a piece of wood (or plywood) on the
table. This will prevent "splintering" or making heavy
burrs on the underside of the workpiece as the drill
breaks through. The wood should contact the left
side of the column.
Using the Vise
For the small workpiece that cannot be clamped to
the table, use a drill press vise. The vise must be
clamped or bolted to the table. Always use a backup piece of scrap wood to cover the table. This
protects both the table and the drill bit.
Basic Operation
Place material to be drilled in such as way as to
come into contact with the left side of the column.
This prevents the material from spinning.
If the work piece is not large enough to come
into contact with the column , use a clamp or drill
press vise that is securely fastened to th e table!
Failure to compl y may cause seri ou s injury!
Operation
Figure 14
Figure 15
Feed the bit into the material with only enough force to
allow the drill bit to work. Feeding too slowly may cause
burning of the workpiece. Feeding too quickly may
cause the motor to stop and/or the drill bit to break.
Generally speaking, the smaller the drill bit, the greater
the RPM required. Wood requires higher speeds than
metal. Metal is usually drilled at slower speeds.
In dusty environments, frequently blow out any dust
that accumulates inside the motor.
Maintenance
Before any intervention on the machine,
disconnect it from the electrical supply by
pulling out the plug or switching off the main
switch! Failure to comply may cause serious
injury.
A coat of automobile-type wax applied to the table
and column will help to keep the surfaces clean.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.
Installing Drills
Insert the drill into the chuck jaws about 1" (25.4mm)
long. When using a small drill do not insert it so far
that the jaws touch the flutes of the drill. Make sure
that the drill is centered in the chuck before
tightening the chuck with the key.
Lubrication
All of the ball bearings are packed with grease at the
factory. They require no further lubrication.
Periodically lubricate the gear, rack, table elevation
mechanism, the splines (grooves) in the spindle, and
the teeth of the quill with a #2 tube grease.

Electrical
230 Volt Operation
Grounding Instructions
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 a risk of electric shock. The
conductor, with insulation having an outer surface that is
green with or without yellow stripes, is the equipmentgrounding 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 three wire extension cords
that have three-prong grounding plugs and three-pole
receptacles that accept the tool’s plug.
Referring to Figure 17:
If 230V, single-phase operation is desired, the following
instructions must be followed:
Disconnect the machine from the power source.
The JET drill press motor has four numbered leads that
are factory connected for 115V operation, as shown in (A).
For 230V operation reconnect the leads as shown in (B).
The 115V attachment plug (C), supplied with the drill
press, must be replaced with a UL/CSA listed plug
suitable for 230V operation (D). Contact your local
Authorized JET Service Center or qualified electrician
for proper procedures to install the plug. The drill press
must comply with all local and national codes after the
230-volt plug is installed.
The drill press with a 230-volt plug should only be
connected to an outlet having the same configuration as
shown in (D). No adapter is available nor should be used
with the 230-volt plug.
Repair or replace a damaged or worn cord immediately.
115 Volt Operation
Referring to Figure 16:
As received from the factory, your drill press is ready to
run at 115-volt operation. This drill press, when wired for
115 volt, is intended for use on a circuit that has an
outlet and a plug that looks like the one illustrated in (A).
A temporary adapter, which looks like the adapter shown
in (B), may be used to connect this plug to a two-pole
receptacle if a properly grounded outlet is not available.
The temporary adapter should only be used until a
properly grounded outlet can be installed by a qualified
electrician. This adapter is not applicable in Canada. The
green colored rigid ear, lug, or tab, extending from the
adapter, must be connected to a permanent ground such
as a properly grounded outlet box.

Extens ion 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 machine will
draw. An undersized cord will cause a drop in the line
voltage resulting in power loss and overheating. The
table following shows the correct size to use depending
on the cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. Remember, the
smaller the gauge number, the heavier the cord.
Length of Cord AWG
000 – 25 Feet 16
025 – 50 Feet 14
The drill press with a 230-volt plug 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 question is properly grounded. If you are not
sure, have a registered electrician check the receptacle.
