GENERAL 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 FOR DRILL PRESSES WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY. 1. DO NOT OPERATE THIS TOOL UNTIL it is assembled and installed according to the instructions. 14. TURN THE MACHINE “OFF” AND WAIT FOR THE DRILL BIT, CUTTING TOOL, OR SANDER TO STOP TURNING prior to cleaning the work area, removing debris, removing or securing workpiece, or changing the angle of the table. A moving drill bit, cutting tool, or sander can be dangerous.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. 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 matching receptacle which will accept the machine’s plug.
EXTENSION CORDS 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 matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. 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.

ASSEMBLY WARNING: FOR YOUR OWN SAFETY, DO NOT CONNECT THE MACHINE TO THE POWER SOURCE UNTIL THE MACHINE IS COMPLETELY ASSEMBLED AND YOU READ AND UNDERSTAND THE ENTIRE INSTRUCTION MANUAL. 1. Assemble the column (A) Fig. 3, to the base (B) using the four screws, three of which are shown at (C). Loosen set screw (D) and remove ring (E) and raising rack (F). E D F A C C B Fig. 3 G 2. Make certain worm gear (G) Figs. 4 and 5, is in place in table bracket (H) as shown. H Fig. 4 H G Fig. 5 3.
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 inside the 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.
7. Thread stud on clamp handle (M) Fig. 12, into hole in rear of table bracket, as shown. M Fig. 12 N O 8. Place the drill press head (N) Fig. 13, onto the column as far as it will go. Align head (A) Fig. 13A, to table (B), and base (C). Tighten the two head locking screws (O) Fig. 13, with wrench supplied. Fig. 13 A B C Fig. 13A 9. Thread the three pinion shaft handles (P) Fig. 14, into the three tapped holes located in the pinion shaft, as shown. P Fig.
. 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 11. IMPORTANT: Open the chuck jaws as wide as possible by turning the chuck sleeve (S) Fig. 16. Fig. 15 12.
FLEXIBLE LAMP A The flexible lamp operates independently of the drill press. To turn the lamp “ON” and “OFF”, rotate switch (A) Fig. 18A. WARNING: To reduce the risk of fire, use 40 watt or less, 120 volt, reflector track type light bulb (not supplied). A standard household light bulb should not be used. The reflector track type light bulb should not extend below the lamp shade. Fig. 18A TABLE ADJUSTMENTS 1.
VARIABLE SPEED CONTROL A IMPORTANT: To avoid damaging the drive belts and pulleys, DO NOT turn speed control handles (A) Fig. 24, unless motor is running. The pilot wheel handles (A) are turned clockwise to increase speed and counterclockwise to decrease speed. The speed range is 500 rpm to 3100 rpm. A DRILLING HOLES TO DEPTH Fig. 24 Where a number of holes are to be drilled to exactly the same depth, the stop nut (A) Fig. 25, on the threaded stop rod (B) is used as follows: 1.
ADJUSTING SPINDLE RETURN SPRING The spindle is automatically returned to its upper most position when the handle is released. It is recommended that the handle be allowed to slowly return to the top position after each hole has been drilled 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 MACHINE FROM POWER SOURCE. 2. Loosen nuts (B) and (E) Fig. 27.
INSTALLING AND REMOVING DRILL BITS C 1. DISCONNECT MACHINE FROM POWER SOURCE. B 2. 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. A D 3. Make certain that the drill bit (A) Fig. 29, is centered in the chuck (B) before tightening the chuck with the key (C). 4. Turn the chuck key (C) Fig. 29, clockwise to tighten and counterclockwise to loosen the chuck jaws. Fig. 29 5.
MAINTENANCE LUBRICATION 1. DISCONNECT MACHINE FROM POWER SOURCE. 2. Remove the six screws (A) Fig. 30 that hold the top cover in place, and remove the top cover. A A 3. 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. IMPORTANT: 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. Fig. 30 B B Fig.
