Make certain that the bottom of the raising rack (F) Fig. 8 is engaged with the flange (K) on the drill press base. FI Fig. 7 F J 9 10 5. Re-install the ring (E) Fig. 9 (removed in STEP 1). IMPORTANT: DO NOT push the ring (E) Fig. 9 all the way down on the the raising rack (F). Make certain that the top of the raising rack (F) is under the bottom of the ring (E) and that enough clearance is available to allow the rack (F) to rotate around the column. Tighten the set screw (D) with the supplied 3mm wrench. Fig. 9 E D S IMPORTANT: Make certain that the spindle taper (Q) Fig. 16 and the tapered hole in the 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. Carefully follow the manufacturer's safety rules concerning its use. IMPORTANT: Open the chuck jaws as wide as possible with the chuck jaws inside the chuck. 13. Hold the chuck on the taper of the spindle. Set the chuck by tapping it with a soft-tipped hammer (T) or a block of wood and hammer (Fig. 17). To avoid damage to the chuck, NEVER drive the chuck onto the spindle with a metal hammer.

Fig. 22 Fig. 23 MOUNTING DRILL PRESS ON A SUPPORTING SURFACE If, during operation, the machine has a tendency to tip over, slide, or walk on the supporting surface, secure the machine base to the supporting surface with an M8x1.25x125mm carriage head screw, 8.5mm flat washer, 8.5mm lock washer, M8x1.25 hex nut through the two holes (A) Fig. 24 located in the machine base. Fig. 24 A MOUNTING THE DRILL PRESS ON A PLYWOOD BASE If you do not fasten your machine permanently, then you must fasten the drill press to a plywood mounting board to prevent it from tipping over. Use a good grade of 3/4" or thicker plywood. DO NOT make the mounting board from particle board. 1. Start with a 21" x 28" or larger piece of plywood. Drill two 3/8" diameter holes (B) Fig. 25 that match the mounting holes (A) Fig. 24 of the drill press base. 2. Fasten the drill press base to the mounting board using the carriage bolts, flat washers, lockwashers, and hex nuts (C) Fig. 25, furnished with your drill press. The holes for the carriage bolt heads and flat washers under the board must be countersunk so that the bolt heads are flush or below the bottom surface of the board. Make sure to use a flat washer, lock washer and hex nut above the drill press base. 3. The supporting board must extend a minimum of 3" beyond each edge of the drill press base (Fig. 26). 4. Secure the plywood base to the floor or supporting surface if the drill press has any tendency to vibrate, slide, or walk during normal operation. 28" MINIMUM 21" MINIMUM C Fig. 25 B Fig. 26 3" Min. 3" Min. 12 OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS STARTING AND STOPPING THE DRILL PRESS 1. The on/off switches (A and B) Fig. 27 are located on the front of the drill press. To turn the machine “ON”, depress the “START” switch. 2. To turn the machine “OFF”, depress the “STOP” switch. Make sure that the switch is in the “OFF” position before plugging in the power cord. In the event of a power failure, depress the “STOP” switch. An accidental start-up can cause injury. LOCKING SWITCH IN THE “OFF” POSITION IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock (C) Fig. 28 with a 3/16" diameter shackle. In the event of a power outage, always lock switch in “OFF” position until the main power is restored. Fig. 27 AB Fig. 28 C TABLE ADJUSTMENTS 1. You can raise or lower the table (A) Fig. 29 by loosening the table clamp handle (B) and turning the table adjusting handle (C). After the table is at the desired height, tighten the handle (B). 2. You can rotate the table (A - Fig. 30) 360 degrees on the table bracket by loosening lock handle (D). 3. You can tilt the table right or left by pulling out and removing the table alignment pin (E) Fig. 31. Loosen the table-locking bolt (F), tilt the table to the desired angle, and tighten the bolt (F). When returning table to the level position, replace the table alignment pin (E) and tighten the bolt (F). 4. A scale and pointer on the table bracket indicates the degree of tilt.
