Presser foot lifter The presser foot can be raised and lowered with presser foot lifter (36). The maximum vertical clearance of 1/4 inch (6.0 mm) for the presser foot for particularly thick fabrics can be achieved by also depressing the presser foot lifter towards the back. Once a thread chain has been created, the presser foot lifter no longer needs to be raised if you continue working with the same thread and presser foot. It is sufficient to gently lift the presser foot using your thumb.
\ Changing the presser foot Switch off the electrical power To remove: Raise the needle(s) to the hig hest position and lift the presser foot. Press the white lever at the rear of the presser foot holder. The sewing foot will be released automatically from the holder and can be removed to the left. To do this, lift the spring slightly.
S ad Disengaging the upper blade Switch off the electrical power Raise upper blade (23 ) to its uppermost po sition by rotating the han dwheel. Detach the trimming waste contain er and open the loo per cover. Now slide the holder of the mo vable upper blade fully towards the right. Turn the head of the upp er blade away from you until the upper blade locks into a hori zontal position.
Fitting the converter Switch off the electrical power The converter must be fitted for all 2-thread seams, for the 2-needle, 3-thread overedge closing seam and for the 4-thread safetystitch seam. Detach the trimming waste container and open the looper cover. Con verter (7) is located in the front of the ma chine housing. Pull it out. Rotate the handwheel in the direction of the arrow until the upper overedge looper (16) is positioned to the right of the movable up per blade.
Setting the bed slide for the stitch width latch For standard overlock seams: Set the bed slide for stitch width latch (21) to position S. For rolled hems and the cover stitch Set the bed slide for stitch width latch (21) to position R. Stitch width latch A will be pushed forward. All standard overlock seams can be sewn with this setting. Stitch width latch A will be pushed back ward. All rolled hems and the cover stitch can be sewn with this setting.
Setting seam width Remove trimming waste container. The seam width can be continuously adjusted as desired from 1/8 to 3/16 inch (3.0 mm to 4.5 mm> by turning the seam width adjustment knob (20). The 2-thread chainstitch is sewn with an interval from 1/8 to 3/16 inch (3.0 mm to 4.5 mm>. The settings are marked on the needle plate. R is the seam width adjustment for rolled seams. Note: The seam width can be more easily adjusted if the looper cover is open. — 3,0mm • (0.
it Setting the stitch length The stitch length can be set as desired from F (4 1 mm> to 4 mm by turning stitch length adjustment knob (35). For most sewing work, the stitch length ad justment knob should be set at 3 mm. When working with close-knit fabrics, set the ad justment knob to 4 mm. Sewing with the free arm Detach the work support Pull the detachable work support (12) for ward slightly, and remove this to the left.
Differential feed The differential feed consists of two feed dogs (A + B), arranged one behind the other, which move the fabric. Adjustment lever (34) regulates the movement of the front feed dog (A), and thus the amount of fabric to be fed through. It can be adjusted within the range 0.5 and 2.0. The standard setting is 1.0, by which the front feed dog (A) moves synchronously with the rear feed dog (B), i.e. the front and rear feed dogs both move the same amount of fabric.
ther Inc (tin tnd iu nt al alec- Set differential feed adjustment lever (34) to 2.0 so that the front feed dog moves twic e as fast as the rear feed dog, i.e. the front feed dog feeds through twice as muc h fa bric as the rear feed dog. As a result, the fabric is gathered. This prevents the seam from becoming stretched when sewing knitted fabri cs such as Jersey and rib stitch goods. The result is a smooth seam (C).
Adjusting the machine to the cover stitch and two-thread chainstitch. Switch off eIectrica power For cover stitch: Turn the handwheel in the direction of the arrow until the needle(s) is in the highest position. Remove the standard presser foot (see page 22). Detach the trimming waste container and open the looper cover. Disen gage the upper blade. Set the bed slide for the stitch width latch to R (see page 25).

I Important notes on sewing with the cover stitch The power table is marked with various units of measurement. The figures on the left are in mm and those on the right are in inches. These values show the distance to the need le, when the stitch width is set at 3.5 mm. Preparing the fabric: It is useful to press under the fabric before hemming it. Depending on as to how wide the seam must be stitched down, you must press under 1/4 inch (0.5 cm) wider.
I 2. If you are not to sew to the edge of the fa bric, i.e. by tubular fabrics: Sew 4 5 stitches on top of each other. Du ring the last stitch, turn the handwhee l to wards you until the needles pierce the fabric and you have heard each needle “click” (just before the needles are in the lowest position). - st a sr After the second “click” turn the handwheel back, until the needles are in the high est po sition.

a Adjusting the thread tension The following pages contain directions for setting thread tensions for all programs. Adjust the tension by turning the tensioning wheel until the dot marker is at the desired setting. The settings for adjusting thread tension are recommendatio ns. Fabric type, yarn quality and needle gauge will influence seam results. For this reason it is always best to sew a test seam to check the interlocking of threads. It may be necess ary to correct the thread tension settings.
