SAVE THESE INSTRUCTIONS Electrical Extension Cords SPEED AND WIRING Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Laboratories (UL) should be used. The no-load speed of this tool is approximately 3,000 rpm. This speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools. Grounding Instructions **Ampere rating (on tool faceplate) 0-2.0 2.1-3.4 3.5-5.0 5.1-7.0 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 a 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. Repair or replace a damaged or worn cord immediately. This tool is intended for use on a circuit that has an outlet like the one shown in figure 1. It also has a grounding pin like the one shown. 7.1-12.0 12.1-16.0 Cord Length Wire Size (A.W.G.) 25' 16 16 16 16 14 14 50' 16 16 16 14 14 12 100' 16 16 14 12 10 — **Used on 12 gauge - 20 amp circuit. NOTE: AWG = American Wire Gauge When working with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters “WA” on the cord's jacket. Before using an extension cord, inspect it for loose or exposed wires, and cut or worn insulation. WARNING: Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a power tool. Failure to do so can result in serious personal injury. WARNING: Check extension cords before each use. If damaged replace immediately. Never use tool with a damaged cord since touching the damaged area could cause electrical shock resulting in serious injury. Electrical Connection This tool is powered by a precision built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the tool does not operate when plugged into an outlet, double check the power supply.

See Figures 20 - 21. Using the vise provided (or similar clamping devices), secure the workpiece to the table. To protect the top surface of the workpiece, use a piece of scrap wood between the vise and the workpiece. Select the proper drill bit based on the hole size desired. For large holes, drill a pilot hole first, using a smaller diameter bit. Unlock the spindle lock lever and the lock knob. Using the feed handles, set the spindle at the desired depth and retighten both the lock lever and lock knob securely. Turning the table adjustment handle, set the table to desired height. NOTE: Make sure the table is free of all loose objects and the bit is not in contact with the workpiece. Plug the electrical cord into power supply and turn the switch ON. Make sure spindle rotates freely. With the motor running, change the spindle speed with the variable speed lever. NOTE: The digital display on the front of the drill press will give you the exact spindle speed. Use the chart below to determine speed for the material and drill size. Once the hole is completed, allow the spindle to return to its normal position. This will automatically raise the chuck and bit. DRILLING TIPS If a large hole is needed, it’s a good idea to drill a smaller pilot hole before drilling the final one. Your hole will be more accurately positioned, rounder, and the bits will last longer. If the hole is deeper than it is wide, back off occasionally to clear the chips. When drilling metal, lubricate the bit with oil to improve drilling action and increase bit life. As you increase the bit size, you may need to reduce the spindle speed. If drilling a through hole, make sure that the bit will not drill into the table after moving through the workpiece.

If cranking becomes difficult, grease gear rack lightly. The ball bearings in the tool are permanently lubricated. MOTOR/ELECTRICAL WARNING: The induction motor is easy to maintain but must be kept clean. Do not allow water, oil, or sawdust to accumulate on or in it. The sealed bearings are permanently lubricated and need no further attention. Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. head assembly and motor housing WARNING: Frequently blow out any dust that may accumulate inside the head assembly and/or motor housing. To prevent accidental starting that could cause possible serious personal injury, turn off the tool, remove the switch key, and unplug the drill press before performing any maintenance or adjustment. Gear Rack Periodically lubricate the worm gear and gear rack in order to keep the vertical movement smooth and to help prolong the life of the drill press. GENERAL MAINTENANCE REMOVING THE SPINDLE/CHUCK Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. The chuck tool is used to remove the chuck and/or spindle when either an attachment is to be used or when large drill bits with a tapered shank are to be used. Unplug the drill press. Lower the spindle until the slots in the spindle are visible. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. Insert the chuck tool into the spindle slot. While supporting the chuck in one hand, tap the chuck tool lightly with a rubber mallet until the chuck and spindle release from the drill press. Remove the chuck tool from the spindle. After using the drill press, clean it completely and lubricate all sliding and moving parts. Apply a light coat of automotivetype paste wax to the table and column to help keep the surfaces clean. 22 troubleshooting Problem Noisy operation Bit burns or smokes Excessive drill runout or wobble Drill bit binds in workpiece Workpiece support loosens Possible Cause Solution Incorrect belt tension Adjust belt tension.
