When finished, release the Connecting Rod and the Bobbin Winder will reset to the ‘OFF’ position. Attaching the Needle 1. Unplug the Power Cord from the electrical outlet. 2. Select a proper needle size according to the thread count and type of material being sewn. 3. Turn the Hand Wheel until the needle bar reaches the highest point of its stroke. 4. Loosen Screw (2) and hold needle (1) with its indented part “A” facing exactly to the right in direction “B”. 5. Insert the needle and push it up until it will go no farther. 6. While holding in place, securely tighten Screw (2). Setting the Bobbin into the Bobbin Case 1. Hold the Bobbin so that the thread exit is to the left, and push the Bobbin into its case. 2. Feed the thread through slit “A” and pull the thread in direction “B”. By doing so, the thread will pass under the tension spring and exit at notch “B”. 3. Verify that the Bobbin rotates in the direction of the arrow when thread “C” is pulled. cbdFigure CFigure Dabcd66cbdFigure CFigure Dabcd66 REV 03/04; REV 04/05 Threading the Machine Head Set the thread spool on its holder and guide the thread through the machine as illustrated above. The numbers in the illustration indicate the threading sequence. Adjusting the Stitch Length 1. To increase the stitch length, turn the Stitch Length Dial (1) to the desired number (in millimeters) as indicated under the scale dot (A) on the machine. 2. To decrease the stitch length, turn the Stitch Length Dial (1), while pressing the Feed Lever (2). Adjusting the Needle Thread Tension 1. Turn Tension Adjustment Knob (1) clockwise (A) to increase thread tension. 2. Turn Tension Adjustment Knob (1) counterclockwise (B) to decrease thread tension. Adjusting the Bobbin Thread Tension 1. Turn the Tension Adjustment Screw (2) clockwise (A) to increase bobbin tension. 2. Turn the Tension Adjustment screw (2) counterclockwise (B) to decrease bobbin tension. Changing the Thread Take-up Spring Stroke and Pressure 1. Loosen Set Screw (2). 2. To increase the stroke, turn the Tension Knob Screw (3) clockwise (A). 3. To decrease the stroke, turn the Tension Knob Screw (3) counterclockwise (B). 4. Loosen Set Screw (2) and pull out the Tension Arm (5). 5. Loosen Set Screw (4) and remove the Tension Knob Screw (3). 6. Turn the Tension Knob Screw (3) clockwise (A) to increase pressure; or turn counterclockwise (B) to decrease pressure. 7. Replace Tension Knob Screw (3), tighten Set Screw (4), and replace the assembly. Setting the Hand Lifter 1. To stop the machine with its Presser Foot up, turn the Hand Lifter (1) up (A). The Presser Foot will go up about 1/4 inch and stop. 2. To set the Presser Foot to its original position, turn the Hand Lifter (1) down (B). Using the Knee Lifter, you can get the standard Presser Foot lift of about 1/2 inch. Setting the Presser Foot Pressure 1. Loosen Nut (2), and turn the Presser Spring Regulator (1) clockwise (A) to increase Presser Foot pressure. 2. To decrease Presser Foot pressure, turn the Presser Spring Regulator (1) counterclockwise. 3. After adjustment, tighten Nut (2). Adjusting the Feed Timing 1. Loosen Set Screws (2) and (3) on the Feed Eccentric Cam (1) and properly position the Eccentric Cam. Retighten the Set Screws. 2. To advance the feed timing in order to prevent uneven material feed, move the Feed Eccentric Cam up (clockwise). 3. To delay the feed timing in order to increase stitch tightness, move the Feed Eccentric Cam down (counterclockwise). Adjusting the Height of the Feed Dog The Feed Dog is factory adjusted so that it juts out from the Throat Plate surface 0.8 mm to 0.9 mm. If the Feed Dog juts out too much, puckering may result when sewing lightweight materials. To adjust the height of the Feed Dog: 1. Loosen Screw (2) of Crank (1). 2. Move the Feed Bar up or down to make the adjustment. 3. Tighten Screw (2), being careful not to overtighten. Adjusting Needle-to-hook Timing 1. Turn the Hand Wheel to bring the needle bar down to the lowest point of its stroke. 2. Loosen Set Screw (1). 3. When using a DBX1 needle, align to marker line “A” on the needle bar (2) with the bottom end of the needle bar lower bushing (3), then tighten Set Screw (1). When using a DAX1 needle, align to marker line “B” on the needle bar (2) with the bottom end of the needle bar lower bushing (3), then tighten Set Screw (1). 4. When using a DBX1 needle, loosen three Hook Set Screws, turn the Hand Wheel, and align the marker line “B” on the needle bar (2) with the bottom end of the needle bar lower bushing (3). When using a DAX1 needle, align the marker line “D” on the needle bar (2) with the bottom end of the needle bar lower bushing (3). 5. After making the adjustments in steps 3 and 4, align the Hook Blade point (5) with the center of the needle (4). Provide a clearance of .001” to .004” (0.04 to 0.1 mm) between the needle and the hook. This clearance is less than 1/64” (almost touching). Securely tighten the three Set Screws. If the clearance is too...
