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.

CONNECTING TOOL TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. 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 3-pole receptacles which accept the tool’s plug. Before connecting the motor to
the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same
characteristics as indicated on the tool. All line connections should make good contact. Running on low voltage will
damage the motor.
MOTOR SPECIFICATIONS
Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure
the switch is in the “OFF” position. The motor provides a no-load speed of 1720 RPM.

cord is in good condition and is a 3-wire extension cord
which has a 3-prong grounding type plug and a 3-pole
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 machine. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Fig. 20, 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.

OPERATION
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.
Fig. 33
WARNING: 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 column, as shown in Fig. 34. 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.
Fig. 34
INSTALLING AND REMOVING DRILL BITS
1. Insert smooth end of drill bit (A) Fig. 35, 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. 35, is centered
in the chuck (B) before tightening the chuck with the key
(C).
D
3. Turn the chuck key (C) Fig. 35, clockwise to tighten
and counterclockwise to loosen the chuck jaws.
B
4. Tighten all three chuck jaws to secure the drill bit
sufficiently so that it does not slip while drilling.
A
5. MAKE SURE chuck key (C) Fig. 35, 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.
C
Fig. 35
13
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. 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 piece 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.

prepaid to a Delta factory service center or authorized service station with proof of purchase of the product within two
years and provides Delta with reasonable opportunity to verify the alleged defect by inspection. Delta may require that
electric motors be returned prepaid to a motor manufacturer’s authorized station for inspection and repair or replacement.
Delta will not be responsible for any asserted defect which has resulted from normal wear, misuse, abuse or repair or
alteration made or specifically authorized by anyone other than an authorized Delta Service facility or representative.
Under no circumstances will Delta be liable for incidental or consequential damages resulting from defective products.
This warranty is Delta’s sole warranty and sets forth the customer’s exclusive remedy, with respect to defective products;
all other warranties, express or implied, whether of merchantability, fitness for purpose, or otherwise, are expressly
disclaimed by Delta.
