SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there
are certain hazards involved with the operation of the product. Using the machine with respect and caution will
considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored,
personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards,
goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make
up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop.
If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your
personal safety is your responsibility.
This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not
be modified and/or used for any application other than that for which it was designed. If you have any questions relative
to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should
be performed on the product.

FASTENING DRILL PRESS BASE TO A
SUPPORTING SURFACE
PERMANENT MOUNTING
If your drill press is to be used in one permanent location, the drill press base must be secured to the supporting
surface with fasteners through the two mounting holes, (A) Fig. 10, in the drill press base.
MOUNTING DRILL PRESS
TO A PLYWOOD BASE
If you do not fasten your drill press in a permanent
manner, the drill press must be fastened to a plywood
mounting board to prevent the drill press from tipping
over during normal use. Use a good grade of plywood
with a minimum 3/4" thickness. Do not make the
mounting board from particle board since particle board
breaks easily.
1. Drill two 3/8" diameter holes 10" apart (B) Fig. 11,
corresponding to the mounting holes (A) Fig. 10, of the
drill press base in a 21" by 28" minimum size plywood
board.
2. Fasten the drill press base to the mounting board
using the carriage bolts, flat washers, lockwashers, and
hex nuts (C) Fig. 11, furnished with your drill press. The
holes for the carriage bolt heads must be countersunk
so that the bolt heads are flush or below the bottom
surface of the mounting board in order to guarantee
proper stability.
3. When the drill press is mounted to the supporting
board, the board must extend a minimum of 3" beyond
each edge of the drill press base, as shown in Fig. 12.
4. The plywood base must be secured to the floor or
supporting surface if there is any tendency of the drill
press to vibrate, slide or walk during normal operation.

CONNECTING TOOL TO POWER SOURCE
POWER CONNECTIONS
A separate grounded electrical circuit should be used for your tool. This circuit should not be less than #12 wire and
should be protected with a 20 amp fuse or circuit breaker. Before connecting the tool 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.
MOTOR SPECIFICATIONS
Your tool is designed to use a 1720 RPM motor. It is wired at the factory for 120 Volts, 60 Hz alternating current. Never
use a motor that runs faster than 1720 RPM.
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. The motor 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.
Repair or replace damaged or worn cord immediately.
IMPORTANT: IN ALL CASES , MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF
YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

OPERA
TION
Your drill press may be converted for 240 volt operation.
The conversion of your drill press for 240 volt operation
must be done by qualified electrical personnel. Should
you desire to have your drill press converted for 240 volt
operation, take your drill press to your local Authorized
Delta Service Center. You can call 800-223-7278 for the
location of the nearest Authorized Service Center.
When converted for 240 volt operation, your drill press is
intended for use on a circuit that has an outlet like the
one illustrated in Fig. 15. After conversion for 240 volts,
the drill press will have a grounding plug that looks like
the plug illustrated in Fig. 15.
Make sure the drill press is connected to an outlet
having the same configuration as the plug. No adapter is
available or should be used when the drill press is
converted for 240 volts. If the drill press must be
reconnected for use on a different type of electrical
circuit, the re-connection should be made by qualified
service personnel; and after re-connection, the tool
should comply with all local codes and ordinances.
Fig. 16
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 a 3-hole receptacle which will accept the tool’s plug. When using an extension
cord, be sure to use one heavy enough to carry the current of the drill press. An undersized cord will cause a drop in
line voltage resulting in loss of power and overheating. Fig. 16, shows the correct gauge to use depending on cord
length and voltage. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

OPERATIONS
Your Drill Press should be used with drill bits that have shank diameters of 5/8" or less.
The following directions 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. IMPORTANT: After installing a drill
bit into the chuck, always tighten the jaws of the chuck using the key supplied in all three locations of the chuck,
two of which are shown at (E) Fig. 30.
IMPORTANT: When the workpiece is long enough, it should always be positioned on the table with one end against
the column, as shown in Fig. 30. 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.

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 square bottom hole and are
designed for removal of woodchips. 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. Scribe
a vertical line on the front of the column and a matchmark on the table bracket, so that the table 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 for 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 in metal. The work should never be held in the bare hand;
the lips of the drill may seize the work at any time, especially when breaking through the stock. If the
workpiece is whirled out of the operator’s hand, he may be injured. The drill will be broken when 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 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.
INSTALLING AND REMOVING DRILL BITS
1. Insert smooth end of drill bit (A) Fig. 31, as far as it
will go into the chuck (B), 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. 31, is centered
in the chuck (B) before tightening the chuck with the key
(C).
3. Turn the chuck key (C) Fig. 31, 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. 31, is removed from
chuck before starting drill press. Your chuck key (C) is
equipped with a self-ejecting pin (D) which eliminates
the hazard of the key being left in the chuck.
