The Bobbin Winder has two positions, ‘ON’ and ‘OFF’: OFF Position The Bobbin Winder won’t contact the belt. WARNING: Shut the machine off completely before working around the needle or other moving parts. ON Position This position is with the Connecting Rod (10-6) pressed, as shown in Figure C. The Shaft on the Bobbin Winder will spin; winding thread onto the Bobbin. Winding Thread Onto the Bobbin 1. Place a Bobbin onto the Bobbin Winder Shaft (10-3) as shown at point d in Figure C, right. 2. Route the Thread from the Spool (not shown) up through the Thread Guide Tube (10-39, point a), the hole in the Thread Tension Bracket Assembly (10-15, b), over and under the far side of the Tension Disc (10-17, c), and connect it to the Bobbin (d). - See Figure D, right. 3. While the Connecting Rod (10-6) is pressed (as shown in both Figures C and D) the Bobbin Winder will be in the ‘ON’ position and the Bobbin will fill with thread. When finished, release the Connecting Rod and the Bobbin Winder will reset to the ‘OFF’ position. 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. 10-6 ON Position 10-6 OFF Position Figure C d b c a Figure D 10-6 d b c Attaching the Needle Replacement Needle Type: 135 X 17 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 facing toward the Presser Bar (5-18). 5. Insert the needle and push it up until it will go no farther. 6. While holding in place, securely tighten Screw (2). Threading the Machine Head Set the thread spool on its holder and guide the thread through the machine as illustrated to the left. 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) to the desired setting. The Feed Lever (2) may require adjustment to allow the Dial to move. Reversing Sewing Direction Depress and hold the Feed Lever (2) to sew in a reverse direction. After the Lever is released, sewing direction will automatically return to forward. 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. Adjusting the Thread Take-up Stroke 1. When sewing heavy weight materials, move the Thread Guide (1) to the left (A) to increase the length of thread pulled out by the Thread Take-up. 2. When sewing lightweight materials, move the Thread Guide (1) to the right (B) to decrease the length of thread pulled out by the Thread Take-up. 3. The normal setting is when the marker line “C” on the Thread Guide (1) is aligned with the center of the screw. Setting the Presser Foot Pressure 1. Loosen Nut (A), and turn the Presser Spring Regulator clockwise (a) to increase Presser Foot pressure. 2. To decrease Presser Foot pressure, turn the Presser Spring Regulator counterclockwise (b). 3. After adjustment, tighten Nut (A). Adjusting the Presser Bar Height 1. Remove the Rubber Plug (C) on the Face Plate (B). Loosen the set screw underneath. 2. Manually adjust the Presser Bar height, and the angle of the Presser Foot. The normal position is 6 mm clearance. 3. After adjusting, retighten the Set Screw and replace the Rubber Plug (C). Check to ensure that the presser foot is not loose. 4. Manually turn the Hand wheel through a full cycle to verify that the presser foot will not contact the walking foot or obstruct the needle. If it does readjust the Presser Foot. Adjusting the Feed Timing 1. Loosen Set Screws (2) ...
