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 com

­mon 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 DRILL PRESS 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 3­prong 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 drill press is designed to use a 1720 RPM motor. It is wired at the factory for 110-120 Volts, 60 Hz alternating cur­rent. Never use a motor that runs faster than 1720 RPM. Your drill press may be converted for 220-240 volt operation.
The conversion of your drill press for 220-240 volt operation must be done by qualified electrical personnel.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

2. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than 150
volts:

This tool is intended for use on a normal 120-volt circuit
and has a grounded plug that looks like the plug illustrat­ed in Fig. A.

If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. B, may be used for connecting the
3-prong grounding type plug to a 2-prong receptacle. 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, or the like extending from
the adapter must be connected to a permanent ground
such as a properly grounded outlet box cover. 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.

1. All grounded, cord-connected tools: 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 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, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

3. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating between 150 ­250 volts, inclusive:

This tool is intended for use on a circuit that has an out­let that looks like the one illustrated in Fig. C. The tool
has a grounding plug that looks like the plug illustrated
in Fig. C. Make sure the tool is connected to an outlet
having the same configuration as the plug. No adapter is
available or should be used with this tool. If the tool
must be reconnected for use on a different type of elec­tric circuit, the reconnection should be made by quali­fied service personnel; and after reconnection, the tool
should comply with all local codes and ordinances.

WARNING: IN ALL CASES, MAKE CERTAIN THE

RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A CERTI­FIED ELECTRICIAN CHECK THE RECEPTACLE.

ADAPTER

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-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 saw. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Fig. D, 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.

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 four mounting
holes, (A) Fig. 16, in the drill press base.

MOUNTING YOUR
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 can
unexpectedly break.

1. Drill four 3/8 diameter holes (B) Fig. 17, corre­sponding to the mounting holes (A) Fig. 16, of the drill
press base in a 26 x 32 minimum size plywood board.

2. Fasten the drill press base to the mounting board
using the carriage bolts, nuts, and washers (C) Fig.17,
furnished with your drill press. The carriage bolt heads
must be countersunk such that the bolt heads are flush
with the bottom surface of the mounting board in order
to guarantee the 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. 18.

OPERATION

Your Drill Press should be used with drill bits 5/8²or less in diameter.

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: When the workpiece is long enough, it should always be positioned on the table with one end
against the column, as shown in Fig. 32. 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. 32

REMOVING CHUCK
AND SPINDLE ADAPTER

If you desire to remove the chuck and spindle adapter,
lower spindle and rotate chuck until the slot in the
spindle lines up with the slot in the quill, as shown in
Fig. 31. Then insert tapered end of drift bar (A) into slot
(B) in quill and remove chuck and spindle adapter.

CORRECT DRILLING SPEEDS

Factors which determine the best speed to use in any drill press operations are: kind of material being
worked, size of hole, type of drill or other cutter, and quality of cut desired. The smaller the drill, the greater
the required RPM. In soft materials, the speed should be higher than for hard metals.

WARNING: Use the recommended speed for the drill press bit and workpiece material. As a guideline
for the speed to use for different drill diameters and materials, refer to the chart located on the inside
top cover of the drill press for your convenience.

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. In any case, 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.

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 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.
