6. Operation 6.1 Threading the Needle Thread Caution Risk of Injury ! Turn the main switch off ! Thread the needle thread only with the sewing machine turned off. – Place the yarn spools on the yarn stand as shown in the illustration and guide the needle and underthreads through the take-off arms. The take-off arms 1 and 3 must lie vertically above the yarn spools. The take-off arms 2 and 4 are to be set as per the drawing. They prevent the two needle threads from hitting each other.

1 A 2 3 10 Illus. a: Correct thread interlacing in the middle of the material Illus. b: Needle thread tension too low or Underthread tension too high Illus.
PAGE 9
6.2 Setting the Needle Thread Tension Main tension 3 The main tension 3 is to be set as low as possible. The interlacing of the threads should lie in the middle of the material (see Illus. a ). Too high thread tensions can lead to unwanted bunching in thin material and thread breakage. – Set the main tension 3 so that a uniform stitch pattern is achieved. Supplimentary tension 2 The switchable supplimentary tension 2 serves for the quick change of the needle thread tension, e.g. at seam thickenings.
PAGE 10
6.4 Setting the Tension Regulator 1 2 3 4 The needle thread quantity required for the hook is adjusted with the tension regulator 2. The setting is dependent on the following factors: - Material thickness - Yarn characteristics - Stitch length A prescisely set tension regulator assures an optimal sewing result at the lowest possible needle thread tension. With a correct setting, the needle thread loop must glide over the thickest point of the hook with little tension.
PAGE 11
6.5 Winding the Underthread 2 3 5 1 – – – – – – 4 6 Thread the underthread as shown in the illustrations. Place the bobbin on the winder shaft 2. Wind the underthread counterclockwise approx. 5x around the bobbin core. Tear off the underthread at thread clamp 3. Swing the winder lever 4 against the bobbin. Set the tension 1. The underthread should be wound up uniformly with little tension. – Bend the guide plate 5. The bobbin should be filled cylindrically and not conically. – Set screw 6.
PAGE 12
6.6 Inserting the Underthread Bobbin 4 1 2 3 5 6 7 8 Caution Risk of Injury ! Turn the main switch off. Change the underthread bobbins only with the sewing machine turned off. Removing the empty underthread bobbin – – Bring the needle bars into the high position. – – Lift the bobbin case flap. Open the needle plate slides 1 and 2. Unlock the right needle plate slide 2 by pressing down on the leaf spring 3. Remove the bobbin case with empty underthread bobbin.
PAGE 13
6.7 Setting the Underthread Tension 1 2 3 4 Caution Risk of Injury ! Turn the main switch off. Set the underthread tension only with the sewing machine turned off. – – – – Take out the bobbin case with bobbin. To lift the bobbin case reach under the nose 3. Set tension spring 2 by turning the adjustment screw 1. Insert the bobbin case with bobbin into the hook again. Note: The spring 4 is to be found under the bobbin in the hook.
PAGE 14
6.8 Inserting and Changing Needles 1 1 Caution Risk of Injury ! Turn the main switch off. Change needles only with the sewing machine turned off. – – – – Bring the needle bars into the high position. Loosen screws 1 (right or left, 1.5 Allan key in the accessories pack). Remove the needles from the needle holder. Insert new needles up to the stop in the holes of the needle holder.

6.9 Lifting the Sewing Feet v a r i o c o n t r o l 7 2 0 + 1 0 6 5 4 E 9 8 7 P 2 3 1 0 I 2 The sewing feet can be raised mechanically or pneumatically. Depending on the equipment of the special sewing machine, the lifting occurs through operation of the knee lever 2 or the stepping back on the pedal. Mechanical sewing foot lift (knee lever 2) – To move the material (e.g. for corrections) operate knee lever 2. The sewing feet remain raised as long as the knee lever 2 is operated.
PAGE 16
6.11 Setting the Sewing Foot Pressure 1 2 A The desired sewing foot pressure is set with sleeve 1. – Increase sewing foot pressure Decrease sewing foot pressure = Turn sleeve 1 clockwise. = Turn sleeve 1 counterclockwise. The setting range can be changed by turning the bolt 2. – – Screw off sleeve 1. – Replace sleeve 1 again and set the desired sewing foot pressure. 18 Take out bolt 2, turn and insert again. Fitting position A = Higher sewing foot pressure.

6.12 Stitch Length on Sewing Machines without Automatic Bartacking 1 2 v a r i o c o n t r o l 7 2 0 8 7 4 5 The desired stitch length is set with the knurled nut 1 in the stitch regulator lever. It is the same for forward and reverse sewing. Changing the stitch length during sewing. With the stitch regulator lever 2 the stitch length can be continuously changed during sewing between the set forward and reverse stitch length. – Stitch regulator lever all the way up.

6.12.1 Stitch Length on Sewing Machines with Automatic Bartacking 1 2 3 Sewing machines with automatic bartacking ( Subclass 381-160162 and 382-160162 ) On sewing machines with automatic bartacking the stitch lengths are set with the knurled nut 3 and the block 1. The knurled nut in the stitch regulator lever (see pos. 1 page 19) is turned completely back. Caution Risk of Injury ! Turn the main switch off. Set the stitch length only with the sewing machine turned off.
PAGE 19
6.13 Turning the Needle Bars On and Off 1 2 The needle bars can be turned off with lever 1. The position of lever 1 determines which needles are working: – Lever 1 in the left position. Left needle bar turned off (right needle bar is working). – Lever 1 in the right position. Right needle bar turned off (left needle bar is working). – Lever 1 in the middle position. Both needle bars are working. The needle bar is arrested in its high position.

6.14 Roller Top Feed 1 2 5 3 4 4 The feed distance of the roller top feed is a max. 7 mm. It can be set differently than the bottom feed with the setting dial 2. The feed roller 3 is automatically lowered after 10 stitches. The number of stitches prior to the automatic lowering of the feed roller can be set with parameter F-186 (technician level). The feed roller 3 is automatically raised during lifting of the sewing foot and at seam bartacking.

10. Optional Equipment 10.1 Thread Wiper If, at the beginning of a seam, the needle thread end is to be drawn through on the underside of the material, then it should not get clamped in between the sewing foot and the material. The thread wiper assures that the needle thread end hangs out of the needle eye loosely. The movement of the thread wiper occurs after the trimming of the thread before the feet are lifted. Note The thread wiper can be turned on and off at the control panel.
