5. Tighten two jam nuts (A, Fig. 10). Do not over-tighten. Nuts should not contact the housing when tight. The jam nuts should be tightened against eachother. Table Tilt Adjustment CAUTION! Remove the alignment pin first and then loosen the hex cap bolt. Failure to comply may cause the table assembly to separate from the column and fall. To tilt the table: 1. Turn nut (D, Fig. 11) clockwise to pull out the alignment pin (E, Fig. 11). 2. Loosen hex cap bolt (F, Fig. 11), and tilt the table to the desired angle. 3. Tighten the hex cap bolt (F, Fig. 11). 4. The alignment pin only works at 90° and must be reinserted when the table is returned to 90°. 14 Basic Operation • Always use a back-up piece of scrap wood to cover the table. This protects both the table and the drill bit. • Place material to be drilled in such as way as to come into contact with the left side of the column. This prevents the material from spinning. .. WARNING! If the work piece is not large enough to come into contact with the column, use a clamp or drill press vise that is securely fastened to the table! Failure to comply may cause serious injury! • Feed the bit into the material with only enough force to allow the drill bit to work. Feeding too slowly may cause burning of the workpiece. Feeding too quickly may cause the motor to stop and/or the drill bit to break. • Generally speaking, the smaller the drill bit, the greater the RPM required. Wood requires higher speeds than metal. Metal is usually drilled at slower speeds. • In dusty environments, frequently blow out any dust that accumulates inside the motor. Lubrication Periodically lubricate the gear and the rack, the table elevation mechanism, the splines (grooves) in the spindle, and the teeth of the quill with a #2 tube grease. 15 Troubleshooting Trouble Probable Cause Remedy Drill press will not start. 1. Drill press unplugged from wall, or motor. 2. Fuse blown, or circuit breaker tripped. 3. Cord damaged. 4. Starting capacitor bad. 1. Check all plug connections. 2. Replace fuse, or reset circuit breaker. 3. Replace cord. 4. Replace starting capacitor. Drill press does not come up to speed. 1. Extension cord too light or too long. 2. Low current. 1. Replace with adequate size and length cord. 2. Contact a qualified electrician. Drill Press vibrates excessively. 1. Stand on uneven surface. 2. Bad belt(s). 1. Adjust stand so that it rests evenly on the floor. 2. Replace belts. Noisy Operation. 1. Incorrect belt tension. 2. Dry spindle. 3. Loose spindle pulley. 4. Loose motor pulley. 1. Adjust belt tension. See “Changing Spindle Speeds”, page 12. 2. Lubricate spindle. See “Lubrication” page 15. 3. Check tightness of retaining nut on pulley, and tighten if necessary. 4. Tighten set screws in pulleys. Workpiece Burns. 1. Incorrect Speed. 2. Chips not clearing from hole or bit. 3. Dull drill bit. 4. Feeding too slow. 1. Change to appropriate speed, see speed and pulley chart, page 13. 2. Retract drill bit frequently to remove chips. 3. Resharpen, or replace drill bit. 4. Increase feed rate. Drill bit wanders. 1. Bit sharpened incorrectly. 2. Bent drill bit. 3. Bit, or chuck not installed properly. 1. Resharpen bit correctly. 2. Replace drill bit. 3. Reinstall the chuck, or bit properly. Wood splinters on the underside. 1. No backing board used. 1. Place a scrap board underneath the workpiece to prevent splintering. Drill bit binds in workpiece. 1. Workpiece pinching the bit. 2. Excessive feed rate. 3. Chuck jaws not tight. 4. Improper belt tension. 1. Support or clamp workpiece. 2. Decrease feed rate. 3. Tighten chuck jaws. 4. Increase belt tension, see page 12. Excessive drill bit runout, or wobble. 1. Bent drill bit. 2. Worn spindle bearings. 3. Bit, or chuck not properly installed. 1. Replace drill bit. 2. Replace spindle bearings. 3. Reinstall the bit, or chuck properly. Quill returns too slow, or too fast. 1. Spring has improper tension. 1. Adjust “Return Spring Tension,” page 14. Chuck, or arbor do not stay in place. 1. Dirt, grease, etc on arbor, chuck, or spindle. 1. Clean all mating surfaces thoroughly with a cleaner degreaser. 16 Parts Breakdown for JDP-17FSE 17 Parts List for JET JDP-17FSE Drill Press Index Part No No. Description Size Qty 1..........10800101.....................
