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.
ADDITIONAL SAFETY RULES FOR DRILL PRESSES 1. DO NOT operate your tool until it is completely assembled and installed according to the instructions. 15. MAKE SURE chuck key is removed from chuck before starting drill press. ONLY use chuck key provided with your drill press. It is equipped with a self-ejecting pin which eliminates the hazard of the key being left in the chuck. 2.
UNPACKING AND CLEANING Your drill press is shipped complete in one container. Carefully unpack the drill press and all loose items from the container. Figure 2 illustrates the drill press and all loose items supplied with the machine. After assembly remove the protective coating from the table surface. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose).
ASSEMBLY A D E 1. Assemble the column (A) Fig. 3, to the base (B) using the four screws (C), three of which are shown. Loosen set screw (D) and remove ring (E) and raising rack (F). F C B C Fig. 3 2. Make certain worm gear (G) Figs. 4 and 5, is in place in table bracket (H) as shown. G H Fig. 4 G H Fig. 5 3. Insert raising rack (F) Fig.
F 4. Slide raising rack (F) Fig. 7, table and table bracket onto drill press column, as shown. Make sure bottom of raising rack (F) Fig. 8, is engaged with flange (J) on drill press base. Fig. 7 F J 5. Re-assemble ring (E) Fig. 9, which was removed in STEP 1. IMPORTANT: Bottom of ring (E) MUST NOT be pushed all the way down onto top of raising rack (F). MAKE SURE top of raising rack (F) is under bottom of ring (E) and that there is enough clearance to allow rack (F) to rotate around the column.

M Fig. 12 9. Place the drill press head (N) Fig. 13, onto the column as far as it will go. Align head to table and base and tighten the two head locking screws (O) with wrench supplied. N O Fig. 13 10. Thread the three pinion shaft handles (P) Fig.
11. IMPORTANT: Make certain the spindle taper (Q) Fig. 15, and tapered hole in chuck (R) are clean and free of any grease, lacquer or rust preventive coatings. NOTE: Household oven cleaner can effectively remove any substance from the spindle and chuck; however, carefully follow the manufacturer's safety rules concerning its use. Q R 12. IMPORTANT: OPEN THE CHUCK JAWS AS WIDE AS POSSIBLE MAKING SURE THE CHUCK JAWS ARE UP INSIDE CHUCK. Fig. 15 13. Carefully drive chuck (S) Fig.
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.
EXTENSION CORDS MINIMUM GAUGE EXTENSION CORD RECOMMENDED SIZES FOR USE WITH STATIONARY ELECTRIC TOOLS Ampere Rating 0-6 0-6 0-6 0-6 6-10 6-10 6-10 6-10 10-12 10-12 10-12 10-12 12-16 12-16 12-16 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 machine.
TABLE ADJUSTMENTS 1. The table can be raised or lowered on the drill press column by loosening the table clamp handle (A) Fig. 23, and turning the table raising and lowering handle (B) Fig. 24. After the table is at the desired height, tighten handle (A) Fig. 23. NOTE: Final positioning of the drill press table should always be from the bottom to the up position. A 2. The table can be rotated 360 degrees on the column by loosening clamp handle (A) Fig.
SPINDLE SPEEDS MOTOR SPINDLE Five spindle speeds of 620, 1100, 1720, 2340 and 3100 RPM are available. 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. 28. Fig. 28, illustrates which steps the pulleys the belt must be placed to obtain the five speeds available. 3100 2340 1720 1100 620 Fig. 28 CHANGING SPEEDS AND ADJUSTING BELT TENSION A D 1. Disconnect the tool from the power source. 2.
ADJUSTING SPINDLE RETURN SPRING A B C The spindle is automatically returned to its upper most position upon release of the handle. It is recommended that the handle be allowed to slowly return to the top position after all holes have been bored in the material. This spring has been properly adjusted at the factory and should not be disturbed unless absolutely necessary. To adjust the return spring, proceed as follows: 1. Disconnect the tool from the power source. Fig. 32 2. Loosen the two nuts (B) Fig.
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.
