Hints for adjusting the thread chain cutter of this sewing machine
Problems with uneven beginning of the thread
34600KCA/ CS112T02-2M111UT
(also see Adjusting Instruction in Catalog 282CA, Page 20 to 25)
1. Make sure that the catching knife - support M (page 40) neither in its right nor in its
left final position hits against the screw (page 40).
In both positions 1 mm of the radius at the end of the guiding slot N (page 38) has
to be visible next to the head of the screw S (page 40) (see also catalog 282CA,
page 22, Fig. 36).
The distance in resting position of the knife carrier M (page 40) can be adjusted
by turning the bolt B (page 40) on the thread of the driving collar L (page 40) as
described above to at least 1 mm. Movement to the left can be limited with the
set collar K (page 36) with the same distance. Tighten screw in set collar K securely.
2. Make sure enough thread is pulled to ensure clean cutting and clamping of the
sewing thread. For this you make a seam, cut off the air and put the needle bar
in its highest position (upper dead center).
Swing in the catching knife completely by pushing against the clevis C (page 36)
of the air cylinder.
Release the clevis again slowly and watch the thread in the area of the take up
hooks H1 to H4 (page 38). Excess thread built up while turning in the catching knife
should be just used up when the catching knife reaches its resting position.
In no way at the end of the movement - in which you have to pull at the clevis C
(page 36) - thread should be pulled from the bobbin through the thread tension.
Is this the case, check the position of the take up hooks H1 to H4. (page 38).
These must be positioned in such a way, that the belonging thread runs closely
underneath without being diverted.
To get more thread increase the movement of the bar 21 (page 38) for the take up
hook H1 to H4 (page 38) by loosening the screw 19 (page 36) and moving it in
small steps upwards until desired thread length is available. Fasten the screws
securely again. Check at the same time if take up hooks H1 to H4 do not hit against
anything or block in some way. Make sure that between take up hooks H2 and
the lower fastening clip of the thread guide strip always a distance of 1 mm remains
when catching knife is turned in - meaning being in its outermost left position.
3. Regulate the speed of the air cylinder with the flow control D (page 36) in such a
way that the speed of the back stroke of the catchingknife is only half the speed
of the forward motion.
4. Please watch for small, approx. 10 mm long u-shaped thread residue inside of the
machine. This is a clue that one or both of the catching knifes cut off the needle
thread loop instead of just cutting it open.
Adjust the knife in the middle of the looper as described in catalog 282CA (S. 22,
Fig. 35).
