GROUNDING INSTRUCTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be
protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong
grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the machine to the
power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of the same characteristics
as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the
machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
Your machine is wired for 120 Volt, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the “OFF” position.
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
2. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating less
than 150 volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A,the machine
will have a grounding plug that looks like the plug illustrated
in Fig. A. A temporary adapter, which looks like the adapter
illustrated in Fig. B, may be used to connect this plug to a
matching 2-conductor receptacle as shown in Fig. B if a
properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician. The green-colored
rigid ear, lug, and the like, extending from the adapter must
be connected to a permanent ground such as a properly
grounded outlet box. Whenever the adapter is used, it must
be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
IN ALL CASES, MAKE CERTAIN THAT THE
RECEPTACLE IN QUESTION IS
PROPERLY GROUNDED. IF YOU ARE NOT
SURE, HAVE A QUALIFIED ELECTRICIAN
CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
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 machine 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 conduc-
tor 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 machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that
accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.

7
EXTENSION CORDS
Use proper extension cords. Make sure
your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type
plug and matching receptacle which will accept the
machine’s plug. When using an extension cord, be sure
to use one heavy enough to carry the current of the
machine. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. Fig.
D-1 shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

To avoid damaging the drive belts and
pulleys, DO NOT turn speed control handles (A) Fig. 24,
unless motor is running. The pilot wheel handles (A) are
turned clockwise to increase speed and counterclockwise
to decrease speed. The speed range is 500 rpm to 3100
rpm.

DRILLING HOLES TO DEPTH
Where a number of holes are to be drilled to exactly the
same depth, the stop nut (A) Fig. 25, on the threaded
stop rod (B) is used as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Insert bit into chuck.
2. Lower the chuck (C) Fig. 25, to the depth you wish
the holes to be drilled. Then lock the quill in position by
tightening quill locking lever (E). NOTE: Quill locking
lever (E) is spring-loaded and can be repositioned by
pulling out on the handle and repositioning the hub of
the handle on the bolt located underneath the hub.
3. Depress spring-loaded button (F) Fig. 25, and rapidly
move stop nut (A) until bottom of nut (A) contacts stop
(G). Then hold the pinion shaft handle and loosen quill
locking lever (E), the chuck and quill will return to the up
position by gradually allowing the pinon shaft handles to
rotate to the return position.
4. Place the material to be drilled on the drill press
table. Raise the drill press table until the material to be
drilled just touches the drill bit.
5. Drill a test hole to check the depth and readjust if
necessary by rotating stop nut (A) Fig. 25, for fine ad-
justment. It is not necessary to depress button (F) while
rotating stop nut (A) for fine adjustment.

QUILL ADJUSTMENTS
The spindle is raised and lowered by means of the pilot
wheel (A) Fig. 26. The quill (B) can be locked at any
desired point in its travel by tightening the quill locking
lever (C). NOTE: The quill locking lever (C) is spring-
loaded and the handle can be repositioned by pulling
out on the handle (C) and repositioning the hub (D) of the
handle on the bolt located underneath the hub.

INSTALLING AND REMOVING DRILL
BITS
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Insert smooth end of drill bit (A) Fig. 29, into chuck
(B), as far as it will go, and then back the bit out 1/16",
or up to the flutes for small bits.
2. Make certain that the drill bit (A) Fig. 29, is centered
in the chuck (B) before tightening the chuck with the key
(C).
3. Turn the chuck key (C) Fig. 29, clockwise to tighten
and counterclockwise to loosen the chuck jaws.
4. Tighten all three chuck jaws to secure the drill bit
sufficiently so that it does not slip while drilling.
5. MAKE SURE chuck key (C) Fig. 29, is
removed from chuck before starting drill press. Your
chuck key (C) is equipped with a self-ejecting pin (D)
which helps minimize the hazard of the key being left in
the chuck.

ADJUSTING SPINDLE RETURN SPRING
The spindle is automatically returned to its upper most position when the handle is released. It is recommended that
the handle be allowed to slowly return to the top position after each hole has been drilled in the material. This spring
has been properly adjusted at the factory and should not be disturbed unless absolutely necessary. To adjust the return
spring:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Loosen nuts (B) and (E) Fig. 27. Make sure spring
housing (A) stays engaged with head casting.
2. While FIRMLY HOLDING spring housing (A) Fig. 27
pull out housing and rotate it until boss (D) is engaged
with the next notch on the housing. Turn the housing
counterclockwise to increase or clockwise to decrease
spring tension. Turn nut (E) until it contacts spring
housing (A), then back nut (E) out a 1/4 turn from spring
housing (A). Tighten nut (B) against nut (E), to hold the
housing in place. IMPORTANT: Inside nut (E) should
not contact spring housing (A) when tightened. Fig. 27
Your drill press is to be used with drill bits with a shank of 1/2" or less in diameter. The following will give the inexperienced
operator a start on common drill press operations. Use scrap material for practice to get a feel of the machine before
attempting regular work.
The use of accessories and attachments not recommended by Delta may result in risk of injury.
IMPORTANT: When the workpiece is long enough it
should always be positioned on the table with one end
against the left side of the column, as shown in Fig. 28.
This prevents the workpiece from rotating with the drill
bit or cutting tool, causing damage to the workpiece or
personal injury to the operator. If it is not possible to
support the workpiece against the column, the
workpiece should always be fastened to the table using
clamps or a vise.

MACHINE USE

15
CORRECT DRILLING SPEEDS
Factors which determine the best speed to use are: kind of material being worked, size of hole, type of drill or other
cutter, and quality of cut desired.
Use the recommended speed for the drill press bit and workpiece material.
BORING IN WOOD
Twist drills, although intended for metal drilling, may also be used for boring holes in wood. However, machine spur bits
are generally preferred for working in wood; they cut a flat bottom hole and are designed for removal of wood chips.
Do not use hand bits which have a screw tip; at drill press speeds they turn into the wood so rapidly as to lift the work
off the table and whirl it.
For through boring, line up the table so that the bit will enter the center hole to avoid damage to the table. Scribe a
vertical line on the front of the column and a matching mark on the table bracket and the drill press head, so that the
table and drill press head can be clamped in the center position at any height.
Feed slowly when the bit is about to cut through the wood to prevent splintering the bottom face. Use a scrap piece
of wood as a base block under the work; this helps to reduce splintering and protects the point of the bit.
DRILLING METAL
Use clamps to hold the work when drilling metal. The work should never be held in the bare hand; the drill bit may seize
the work at any time, especially when breaking through the stock. If the piece is whirled out of the operator's hand, the
operator may be injured. The drill bit will be broken if the work strikes the column.
The work must be clamped firmly while drilling; any tilting, twisting or shifting results not only in a rough hole, but also
increases drill bit breakage. For flat work, lay the piece on a wooden base and clamp it firmly down against the table
to prevent it from turning. If the piece is of irregular shape and cannot be laid flat on the table, it should be securely
blocked and clamped.

SOURCE.
1. Remove the six screws (A) Fig. 30 that hold the top
cover in place, and remove the top cover.
2. The variable speed pulleys should be oiled weekly
with a few drops of light machine oil in the two oil holes
(B) Fig. 31, located on top of the variable speed pulleys.
Oil the holes when the drill press is
turned OFF. Then turn the machine ON and run
through the low and high speed ranges a few times.

MAINTENANCE
KEEP MACHINE CLEAN
Periodically blow out all air passages with dry compressed
air. All plastic parts should be cleaned with a soft damp
cloth. NEVER use solvents to clean plastic parts. They could
possibly dissolve or otherwise damage the material.
Wear ANSI Z87.1 safety glasses while
using compressed air.
FAILURE TO START
Should your machine fail to start, check to make sure the
prongs on the cord plug are making good contact in the
outlet. Also, check for blown fuses or open circuit breakers
in the line.
LUBRICATION
Apply household floor paste wax to the machine table and
extension table or other work surface weekly.
PROTECTING CAST IRON FROM RUST
To clean and protect cast iron tables from rust, you will
need the following materials: 1 pushblock from a jointer,
1 sheet of medium Scotch-Brite™ Blending Hand Pad, 1
can of WD-40®, 1 can of degreaser, 1 can of TopCote®
Aerosol. Apply the WD-40 and polish the table surface
with the Scotch-Brite pad using the pushblock as a
holddown. Degrease the table, then apply the TopCote®
accordingly.
