2. LOOPER
At the end of each stroke the needle yarns are surrounding the looper and the
threads are pulled to form the stitch. This repetitive movement is in the end making a
groove in the looper. This groove will cause thread breakage, and faulty stitches. At
that moment the looper should be replaced. To avoid this situation, it is advised to
check the quality of the looper on regular bases
(one time a day).
Replacement of the looper
 Loosen the screw 27357V and remove the spreader 27103 Fig 7
 Loosen screw 27263V
 Remove the looper in its looperholder

Loosen the screws 27264V in the holder
 Replace the looper 27264 with a new one
 Place the looper in a parallel position with the looper holder
 Replace the looper holder again on its axis
 Position the looper correctly (follow instruction in following paragraph)
 Replace the spreader
POSITIONING OF THE NEEDLE COMPAIRED TO THE LOOPER
It is clear that the needle and the looper have to pass very near to each other without
touching each other. Therefore after replacement of one of these parts or both the
position of these parts should be carefully checked in order to obtain a perfect stitch.
Proceed of follows :
 Turn the flying wheel and put the needle in its highest position.
 Check that the distance between the point of the needle and the needle plate is
exactly : 19 mm.
 Turn the flying wheel and bring the looper in its most backwards position.
 The distance between the point of the looper and the central axe of the needle
should be 3 mm Fig7
.
 When turning further at the flying wheel, check it the point of the looper passes
exactly in the middle of the flat side of the needle and that the distance between
the looper and the needle at that point is about 0.1 mm.
 Check also the position of the needle guide . The needle guide should be
positioned in such a way that it is very near the needle but it doesn’t touch it.
 Turn the flying wheel further and check also if : when the looper is coming back , it
crosses the needle exactly in the center of the flat side of the needle (as seen in
FIG 8).
