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 DRILL PRESS TO POWER SOURCE
POWER CONNECTIONS
EXTENSION CORDS
Use proper size extension cords. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current to your machine. An undersized cord will cause a drop in line voltage resulting in a loss of power and overheating. Fig. 11, shows the size cord to use depending on cord length.
If in doubt, use the next heavier gauge. The smaller the gauge number, the larger the cord size. Use only 3 wire extension cords which have 3-prong grounding type plugs and 3-pole receptacles which will accept the drill press plug.
Fig. 11
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 fuse. Have a certified electrician replace or repair a damaged or worn cord immediately. 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 stamped on motor nameplate. Running on low voltage will damage the motor.

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. 12.
If a properly grounded outlet is not available, a temporary adapter, shown in Fig. 13, 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. 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.
CAUTION: IN ALL CASES, MAKE CERTAIN THE RE­CEPTACLE IN QUESTION IS PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE A CERTIFIED ELEC­TRICIAN CHECK THE RECEPTACLE.
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. 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. 12.
Repair or replace damaged or worn cord immediately.

SPINDLE SPEEDS
Five spindle speeds of 620, 1100, 1720, 2340 and 3100 RPM are available with your drill press. The highest speed is obtained when the belt is on the largest step of the motor pulley and the smallest step of the spindle pulley, as shown in Fig. 14. Fig. 14, illustrates which step of the motor and spindle pulley the belt must be placed to obtain the five speeds available.
WARNING: MAKE SURE THE TOOL IS DIS-
CONNECTED FROM THE POWER SOURCE. NOTE: A BELT POSITIONING SPEED CHART (E) FIG.
16, IS CONVENIENTLY LOCATED ON THE INSIDE TOP COVER OF THE DRILL PRESS.
1. Lift up the belt and pulley guard (A) Fig. 16.
2. Release belt tension by loosening tension lock knob (B) Fig. 16, and pivoting the motor toward the front of the drill press.
3. While holding the motor toward the front of the drill press head, position the belt (C) on the desired steps of the motor and spindle pulleys, as shown in Fig. 16.
4. After the belt is positioned on the desired steps of the motor and spindle pulleys, pivot motor away from the drill press head until the belt is properly tensioned and tighten tension lock knob (B) Fig. 17. The belt should be just tight enough to prevent slipping. Excessive tension will reduce the life of the belt, pulleys and bearings. Correct tension is obtained when the belt (C) can be flexed about 1" out of line midway between the pulleys using light finger pressure.

DRILLING HOLES TO DEPTH
Where a number of holes are to be drilled to exactly the same depth, the stop nuts on the threaded stop rod are used as follows:
1. Lower the spindle until the pointer (A) Fig. 25, lines up with the mark on the scale (B) you wish the depth to be. Then thread the lower stop nut (C) down to contact the depth stop (D) on the side of the head. Return the spindle to the up position and tighten the upper stop nut (E) against the lower stop nut (C).
2. Drill a test hole to check the adjustment and re­adjust if necessary. All holes will be drilled to the depth indicated by the setting of the lower stop nut (C) Fig. 26, as it contacts the depth stop (D) when the spindle is lowered.
Fig. 27
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. 27. 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.
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.

CORRECT DRILLING SPEEDS
Factors which determine the best speed to use in any drill press operations are: material, size of hole, type of drill or other cutter, and quality of cut desired. The smaller the drill, the greater the RPM required. When drilling in soft materials, use a higher speed than what would be used for harder materials.
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 operators 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.
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.
