    Fig. 6 Fig. 7 Screw the control knob (1) onto the shaft or the adjustment bolt (2) until the control knob contacts the handwheel. Hold the control knob tight and screw out the adjustment bolt until the pointer (3) on the control knob of the handwheel (marking 5), (large stitch), contacts and can be slightly seen between handwheel and stand.

  • Page 20: Setting Of The Needle And Transport Movement

    Fig. 8 Setting of the needle and transport movement If the largest stitch length is set (see " 2.5 Abridged version of adjustment manual"), the transport movement is ended when the needle point is located about 1.5 mm within the plate edge before the piercing. Transport beginning is when the needle has left the material and is located about 1 mm behind the plate edge.

  • Page 21: The Looper Movement

    The looper movement The looper movement is determined by the stroke of the looper eccentric (F) Fig. 4) or (1) (Fig. 9), by the crank distance and by the bore distance of the clamping lever (2) (Fig. 9). The looper movement has to equal temporally the needle bar movement.

  • Page 22: Setting The Looper Eccentric

    Fig. 9 4.5.2 Setting the looper eccentric Set the looper eccentric (1) (at position "1") so that its surface is horizontal ( Fig. 9). During a later partial rotation of about 100° at the handwheel (position "2"), the back-most needle position is reached. The looper is positioned then about 2 mm left of and about 3 mm over the needle, differently depending on the loop stroke (Fig.

  • Page 23: Setting The Front Crank

    4.5.3 Setting the front crank Set the front crank (9) vertically at position "1". The looper height movement is influenced by the front crank (9). (Fig. 9) In the front position, the looper comes higher and should pass very closely (0.1 - 0.15 mm) over the needle for a good loop pick-up.

  • Page 26: Tread Lifting In The Needle Bar Head

    Tread lifting in the needle bar head The lifter bar (4) for the tread lifting in the needle bar head has to be set so that the thread can be lifted when the looper stands vertically over the needle as the needle retracts and the loop pick-up is done up to the moment when the looper has reached the needle centre with the left looper point as the needle advances.

  • Page 27: Needle Setting

    4.10 Needle setting The setting dimension for the needle bar can be found in the table in point " Abridged version of adjustment manual". 4.10.1 Height adjustment of the needle (Fig. 13) Using this special construction, the height of the needle can be adjusted. This device proves to be quite useful when using different needle thicknesses.

  • Page 28: Replacing The Looper

    4.11 Replacing the looper After loosening the clamping screw (1) ( Fig. 14) at the head of the looper shaft (2), the looper can be removed. When inserting a new looper, make sure that it contacts the needle or feed cup neither when it is in the front nor when it is in the rear position(see also installation dimension (L), point "2.5 Abridged version of adjustment manual").
