Tension Discs (27a) on the top of the machine. Pass the thread up through the right 2. eyelet then down through the left eyelet on the 3-Hole Thread Eyelet (31a). Pass the thread between the two Thread 3. Tension Discs (7a) pulling to the right until the thread catches in the Take-up Spring (9a). Then pass under the Thread Release Finger (31d) and behind the Thread Guide (35a). Pass behind the Thread Take-up Cover 4. (17a), through the Thread Take-up Eyelet (1b) from right to left, and down through the Faceplate Thread Guide (34a). Pass the thread into the Wire Needle Bar 5. Thread Guide (26c), through the hole in the Needle Bar Thread Guide (24c), through the Needle (23c) from left to right, under the wire guide and between the opening in the Presser Foot (9d). To pull the bobbin thread up to the top 6. of the machine, hold the top thread behind the Presser foot and turn the Hand Wheel (7b) counterclockwsie until the Needle catches the bobbin thread, Threading the Top Thread Set the spool of thread (sold separately) onto the top thread Spool Pin (40i), (the left Spool Pin), and thread it through the eyelet directly above on the Thread Hanger (28i). Guide the thread through the machine, following the steps and photos below. Note: There are two Spool Pins (40i). The left Pin is commonly used to hold the spool of thread for the top thread (the thread that passes through the top section of the machine), while the right Pin is used to hold the spool of thread that is used for winding the bobbin.

Adjusting the Stitch Length Figure 26Stitch Length Dial (46e) To increase or decrease the stitch length, turn the Stitch Length Dial (46e) to the desired number (in millimeters) as indicated at (A) above. Adjusting the Needle Thread Tension Figure 27Tension Adjustment Knob (3a) 1. Turn Tension Adjustment Knob (3a) clockwise to increase thread tension. Turn Tension Adjustment Knob 2. counterclockwise to decrease thread tension. Adjusting the Bobbin Thread Tension Figure 28Increase TensionDecrease TensionBobbin Case (21c) Tension Adjustment Screw 1. Using a small flathead screwdriver (sold separately), turn the Tension Adjustment Screw on the Bobbin Case (21c) clockwise to increase bobbin tension. Turn the Tension Adjustment Screw 2. counterclockwise to decrease bobbin tension. Raising the Presser Foot The Presser Foot (9d) can be raised and lowered using the Presser Foot Lever (18d) or the Knee Lifter (21g). The Knee Lifter raises the Presser Foot momentarily (to a height of up to 1/2”), as long as it is pushed, while the Presser Foot stays in the raised or lowered position when using the Presser Foot Lever. REV 10b Figure 29Presser Foot Lever (18d) Raises Presser FootLowers Presser Foot 1. To raise the Presser Foot, turn the Presser Foot Lever up. The Presser Foot will go up about 1/4” and stop. To lower the Presser Foot, turn the 2. Presser Foot Lever down.

Loosen the Presser Spring Regulator Nut (19d) by turning it counterclockwise. Turn the Presser Regulator (20d) 2. clockwise to increase Presser Foot pressure and counterclockwise to decrease Presser Foot pressure. After adjustment, tighten the Presser 3. Spring Regulator Nut. ADVANCED SETTINGS The Sewing Machine is set at the factory for using with jean weight materials. The following adjustments are needed only when using the machine for unusual types of fabric or when changing machine components. These procedures should be performed only by a qualified sewing machine technician. Adjusting the Feed Timing Set ScrewsRotating Hook (20c) Figure 31 1. Loosen Set Screws on the side of the Rotating Hook (20c) and re-position the Rotating Hook as follows: To advance the feed timing in order to a. prevent uneven material feed, rotate the Rotating Hook up (clockwise). To delay the feed timing in order to b. increase stitch tightness, rotate the Rotating Hook down (counterclockwise). Retighten the Set Screws.2. Adjusting Feed Dog Height The Feed Dog is factory adjusted so that it juts out from the Throat Plate surface .031” (0.8 mm) to .035” (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 ...
