GENERAL SAFETY RULES Safety is a combination of common sense, staying alert and knowing how your item works. SAVE THESE SAFETY INSTRUCTIONS. WARNING: To avoid mistakes and serious injury, do not plug in your tool until the following steps have been read and understood. 1. READ and become familiar with this entire instruction manual. LEARN the tool’s applications, limitations, and possible hazards. 2. AVOID DANGEROUS CONDITIONS. Do not use power tools in wet/damp areas or expose them to rain.
GENERAL SAFETY RULES 15. DO NOT OVERREACH. Keep proper footing and balance at all times. Wear oil-resistant rubber-soled footwear. Keep the floor clear of oil, scrap, and other debris. 16. MAINTAIN TOOLS PROPERLY. ALWAYS keep tools clean and in good working order. Follow instructions for lubricating and changing accessories. 17. CHECK FOR DAMAGED PARTS. Check for alignment of moving parts, jamming, breakage, improper mounting, or any other conditions that may affect the tool’s operation.
SPECIFIC RULES FOR DRILL PRESS 10. Always stop the drill before removing scrap pieces from the table. 11. Use clamps or a vise to secure a workpiece to the table. This will prevent the workpiece from rotating with the drill bit. 12. Do not wear gloves when operating a drill press. 13. Set the drill press to the speed that is appropriate for the material being drilled. 14.
ELECTRICAL INFORMATION GUIDELINES FOR USING 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 your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.
ASSEMBLY AND ADJUSTMENTS UNPACKING Unpack the drill press and all of its parts. Compare against the list below. Do not discard the carton or any packaging until the drill press is completely assembled. To protect the drill press from moisture, a protective coating has been applied to the machine’s surfaces. Remove this coating with a soft cloth moistened with kerosene or WD-40®. Do not use acetone, gasoline, or lacquer thinner to clean. Apply a coat of good paste wax to the table and column.
ASSEMBLY AND ADJUSTMENTS 3 2 COLUMN ASSEMBLY TO BASE 1. Place the column tube (Fig. A - 2) on the base (Fig. A - 1), aligning the column support holes to the base holes. 2. Install a hex head bolt (Fig. A - 3) in each column support hole and tighten bolts using the adjustable wrench. TABLE TO COLUMN 1. Loosen set screw (Fig. B - 2) in rack collar (Fig. B - 1) and remove the collar and the rack (Fig. B - 3) from the column. 1 Fig. A 2 1 5 3 4 6 2. Insert the rack (Fig.
ASSEMBLY AND ADJUSTMENTS DRILL PRESS HEAD TO COLUMN CAUTION: The drill press head is heavy. To avoid injury, two people should lift it into position. 1. Carefully lift the drill press head assembly and position it over the column (Fig. D). 2. Place the mounting opening on the drill press head over the top of the column. Make sure the drill press head is seated properly on the column. 3. Align the direction of the drill press head with the direction of the base and the table. Fig. D 4.
ASSEMBLY AND ADJUSTMENTS MOUNT THE DRILL PRESS The drill press must be securely fastened through the mounting holes (Fig. J - 1, Fig. K) to a stand or workbench with heavy-duty fasteners. This will prevent the drill press from tipping over, sliding, or walking during operation. IMPORTANT: If the stand or workbench has a tendency to move during operation, fasten the workbench securely to the floor. INSTALL THE CHUCK 1. Inspect and clean the taper hole in the chuck and the chuck arbor.
ASSEMBLY AND ADJUSTMENTS RAISE OR LOWER THE TABLE 1. Loosen the support lock handle (Fig. N - 2) and turn the crank handle (Fig. N - 1) until the table is at the desired height. 1 2. Tighten the support lock handle (Fig. N - 2) before drilling. ROTATE THE TABLE 1. Loosen the support lock handle (Fig. N - 2) and turn the table around the column to the desired position. 2 Fig. N Note: The rack should rotate around the column with the table support bracket.
ASSEMBLY AND ADJUSTMENTS WARNING: To avoid injury, make sure the chuck key is removed from the chuck before starting any drilling operation. INSTALLING A DRILL BIT 1. Place the chuck key into the side keyhole of the chuck, meshing the key with the gear teeth. 2. Turn the chuck key counterclockwise to open the chuck jaws. Fig. Q 3. Insert a drill bit into the chuck far enough to obtain the maximum grip of the chuck jaws. 4. Center the drill bit in the chuck jaws before the final tightening of the chuck.
ASSEMBLY AND ADJUSTMENTS ADJUSTING THE LASER WARNING: Do not stare directly at the laser beam. Please observe all safety rules. • Never aim the beam at a person or an object other than the workpiece. • Do not project the laser beam into the eyes of others. • Always make sure the laser beam is aimed at a workpiece that does not possess reflective surfaces, as the laser beam could project into your eyes or the eyes of others. 1 2 Fig. S 1. Place a workpiece on the table. 2.
ASSEMBLY AND ADJUSTMENTS ANGULAR “PLAY” OF THE SPINDLE Move the spindle to the lowest downward position and hold in place. Try to make the spindle revolve around its axis while also moving it with a side motion. If there is too much “play”, proceed as follows: 1. Loosen the lock nut (Fig. V - 1). 2 2. Without obstructing the upward and downward motion of the spindle, turn the screw (Fig. V - 2) clockwise to eliminate the “play.” Note: A little bit of “play” is normal. 1 5 Fig. V 3.
OPERATION INSTALLING A DRILL BIT 1. With the switch OFF, open the chuck jaws (Fig. X - 1) using the chuck key (Fig. X - 2). Turn the chuck key counterclockwise to open the jaws. 2. Insert the drill bit (Fig. X - 3) into the chuck far enough to obtain the maximum gripping by the jaws, but not far enough to touch the spiral grooves of the drill bit when the jaws are tightened. 3. Make sure the drill is centered in the chuck. Turn the chuck key (Fig. X 2) clockwise to tighten the jaws. Fig.
OPERATION Drilling an unmeasured blind hole (not all the way through the workpiece) to a given depth can be done using either the depth scale method or the workpiece method. DRILLING SPEEDS There are a few important factors to keep in mind when determining the best drilling speed: • Material type • Hole size • Drill bit or cutter type • Quality desired Smaller drill bits require greater speed than larger drill bits. Softer materials require greater speed than harder materials.
OPERATION FEEDING THE DRILL BIT • Pull down on the feed handles with only enough force to allow the drill bit to cut. • Feeding too rapidly might stall the motor, cause the belt to slip, damage the workpiece, or break the drill bit. • Feeding too slowly will cause the drill bit to heat up and burn the workpiece. MECHANICAL VARIABLE SPEED This is a mechanical variable speed drill press. To increase or decrease the speed when operating, raise or lower the speed handle (Fig. AA - 1).
TROUBLESHOOTING PROBLEM Noisy operation SOLUTIONS 1) Adjust the belt tension 2) Lubricate the spindle 3) Tighten the retaining nut on the pulley insert 4) Tighten the set screw on the side of the motor pulley The drill bit burns or 1) Drilling at the incorrect speed 1) Change the speed smokes 2) The wood chips are not coming out 2) Retract the drill bit frequently to clear the of the hole chips 3) Dull drill bit 3) Resharpen or replace the drill bit 4) Feeding the workpiece too slowly 4) Feed fast enough t
