the right pedal is pressed back.
Thread trimmer (optional)
4.12.1
Before mounting the thread trimmer, the 2 threaded pins (10) (
Calibration
Fig. 24) in the
stand need to be removed. Then the thread trimmer is mounted on the stand
with the 2 supplied screws. It is aligned so that the thread puller, when it is
extended, DOES NOT collide with the feed cup, looper and needle and picks
up the thread between needle and looper.
CAUTION: The needle position needs to be adjusted for the thread trimmer
before the thread trimmer is put into operation.
More Details see point „4.14.3 Adjustment of the needle position
for the use of our thread trimmer“.
The thread trimmer can be checked by triggering the button (1) on the backside
of the valve, which is mounted on the thread trimmer, using a pointed object
(e.g. ballpoint pen).
