GROUNDING INSTRUCTIONS

THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRIC SHOCK.

1. All grounded, cord-connectedmachines:

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 equipmentgrounding 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-groundingconductor 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 equipmentgrounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect theequipment-groundingconductor to a live terminal.

Check with a qualified electrician or service personnel if t h e g ro u n d i n g i n s t r u c t i o n s a re n o t c o m p l e t e l y understood, or if in doubt as to whether the machine is properly grounded.

Use only 3-wireextension cords that have3-pronggrounding type plugs and matching3-conductorreceptacles that accept the machine’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connectedmachines 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 matching2-conductorreceptacle 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. Thegreen-coloredrigid 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.

Delta Dp350 Parts List

OPERATION

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.

Fig. 28

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 aself-ejectingpin (D) which helps minimize the hazard of the key being left in the chuck.

Delta Dp350 Manual Online

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.

MAINTENANCE

LUBRICATION

DISCONNECT MACHINE FROM POWER 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.
