6 Machine cover The machine cover protects the machine from dust and dirt. When the sewing process is fi nished, push the telescopic thread guide 32 together. The spool stand 34 must be pushed to its full extent in to the machine, regardless of whether a spool is attached.
7 F or USA and Canada This appliance has a polarized plug (one blade wider than the other). To reduce the risk of electric shock, it is designed to fi t into a polarized outlet only one way. If the plug does not fi t correctly into the outlet, reverse the plug.
8 Looper cover Push the looper cover 7 fully to the right and then swivel it down. Five types of stitches and their threading paths are portrayed in color on the inside of the looper cover. Note: The electricity supply of the machine is cut off as soon as the looper cover or swivel plate 12 is opened, for safety reasons, i.
9 Spool holder Before placing thread cones/spools on machine you must pull the spool holder 34 fully away from the back of machine. T elescopic thread guide Pull the telescopic thread guide 32 upwards to its highest position. To ensure optimum thread feed, turn the tele- scopic parts slowly until you hear the locking balls fl ick into place.
10 Spool disc/cone thread adapter It is advantageous to use the spool disc 37 when sewing with large spools (5,000 - 10,000 m). To do this, place the cone thread adapter 36 onto the spool pin 35 . With synthetic threads, the spool discs help eliminate vibration of the cones/spools aiding in smoother feeding of the threads.
11 Presserfoot With standard presser foot 10 use setting ”A” on the spring loaded presser foot latch for the cover stitch (Prog. 02), the 2 thread chainstitch (Prog. 01), the 5 thread safety stitch seam (Prog. 09) and the 4 thread safety stitch seam (Prog.
12 Needle position This machine has 4 needle positions and can sew with a maximum of two needles at any one time. The needle positions are L1, L2, R1 and R2. The fastening screw is located directly above the corresponding needle. The different needle positions are depicted in a schematic drawing in the instruction manual.
13 Changing the needle T urn off the electrical power T o remove: Lower the presser foot and move the needle(s) to the highest position by turning the handwheel towards you. Push the needle inserting tool (from the accessory box 47 ) from below upward fully over the needle.
14 Threading the thread guides Place the spools on the spool pins 35 . You will fi nd information on the thread net, thread unreeling disc, spool disc and cone thread adapter on pages 9 and 10 . Thread through the thread guides 31 from the back to the front fol- lowing the colored threading paths.
15 Threading the upper overedge looper (pink) Turn the handwheel towards you until the up- per overedge looper 18 is in its highest position. Thread in a sequence of 1 to 8.
16 Threading the lower overedge looper (yellow) Turn the handwheel towards you until the lo- wer overedge looper 19 is on the extreme right. Thread in a sequence of 1 to 10.
17 Thread through the thread guides 1 to 8 , marked yellow. Thread from the front through the eye of the lower overedge looper C (= threading point 10 ). Press lever A downwards and hook the thread into guide B . Please also refer to the drawing below.
18 Threading the two-thread chainstitch looper and cover stitch looper (violet) for the chainstitch Turn the handwheel towards you until the two-thread chainstitch looper 20 is on the extreme right.
19 Thread the thread guides which are marked with a violet square in a sequence of 1 to 9. Thread from the front through eye C of the two thread chainstitch looper and the cover stitch looper (= threading point 11). Push lever A upward and hook the thread into slot B .
20 Exception: Threading the two-thread chainstitch looper and cover stitch looper for the cover stitch (violet) (prog. 02) Turn the handwheel towards you until the two thread chainstitch looper 20 is on the extreme right. Thread in a sequence of 1 to 10.
21 Thread the thread guides, as shown in the diagram, in a sequence of 1 to 8 . Some of the threads guides are marked with a violet square. Thread from the front through eye C of the two-thread chainstitch looper and the cover stitch looper (= threading point 10).
22 Threading the needles Thread in a sequence of 1 to 8 . The thread must be guided through the lower slot of thread guide 4 . Pull approximately 4” (10 cm) of thread through the looper and place it to the left under the presser foot. Note: For the cover stitch the thread must also be guided through the lower thread guide 7 .
23 Exception: Threading needle L2 when sewing a 5- thread safety-stitch seam (Prog. 09), a 4-thread safety-stitch seam (Prog. 08) and a 2-thread chainstitch (Prog. 01) Thread in a sequence of 1 to 9. The thread must be guided through the upper slot of thread guide 5.
24 Important note on threading The needle(s) must always be threaded last so that the needle threads do not run under the looper thread as seen in drawing 1 , but instead over the looper thread as depicted in drawing 2 . Should this sequence not be followed, thread breakage or missed stitches can occur.
25 Needle threader Move the needle(s) into the highest position and lower the presser foot. Place the thread from right to left in notch A of the needle threader (to be found in the accessory box). One of the two triangles must point upwards. Place the needle threader onto the front groove of the needle.

29 Thread chain cutter After fi nishing the seam, sew an approx. 6” - 8” (15 - 20 cm) long thread chain. Pull the thread chain from the right to left over the th- read chain cutter 33 .
30 Disengaging the upper bladet T urn off the electrical power Move the movable upper blade 23 into its hig- hest position by turning the handwheel towards you. Remove the waste container and open the looper cover and the swivel plate. Push the knob for lowering the upper blade 27 fully to the right.
31 Swiveling stitch width latch F or standard overlock seams: The swiveling stitch width latch 22 remains in the basic position when sewing all types of standard overlock seams (exception: Program 01, 02). F or rolled hems: Pull knob ( A ) to the right and swivel the swive- ling stitch width latch 22 downwards.
32 Attaching the converter T urn off the electrical power Push the tip of the converter into the back side of the upper overedge looper until it clicks into place and push the converter onto the overedge looper bracket. To remove the converter, gently push the point of the converter from the eye of the upper overedge looper.
33 Setting the seam width The required seam width can be adjusted anywhere between 3.5 and 6 mm by turning the adjusting knob for seam width 13 . The setting can be seen through the viewing window 14 . The two thread chainstitch is sewn with a clea- rance of 6.
34 Adjusting the machine to the cover stitch (Prog. 02) and two thread chainstitch (Prog. 01) This is only necessary if you do not want to trim the fabric edge. Insert the needle(s) (see page 13) according to the overview of the threading paths and threading sequences (see page 26).
35 Press the power table 45 downwards into the designated slot on the looper cover. Close looper cover. Note: Please ensure that the upper overedge looper is disengaged before attaching the power table 45.
36 Differential feed The differential feed consists of two feed dogs (A + B) , one behind the other, which feed the fabric. The movement of the front feed dog (A) and thus the amount of material to be fed can be regulated using the regulator wheel 41 .
37 Set the regulator wheel for the differential feed 41 to 2.0. Here the front feed dog feeds twice as fast as the rear feed dog. This means that the front feed dog feeds twice as much fabric as the rear feed dog, causing the material to gather.
38 Adjusting the stitch length You can set the desired stitch length between 0.5 mm to 4.0 mm by turning the stitch length adjustment knob (42) . Note: For the two thread chainstitch, the setting should be 3.0 or higher. Removing the needle plate Raise the presser foot and move the needle(s) to the highest position.
39 Securing the upper blade T urn off the electrical power It is recommended to secure the movable upper blade 23 before sewing heavy fabrics. Raise the needle(s) to its highest position and open the swivel plate. Tighten the screw fully using the Allen key.
