E - MACHINE ADJUSTMENTS
15. THREAD DRAW OFF
1. Adjustment of the end thread
If there are some skipped stitches at the beginning of sewing or the cycle is not finished, do the
following:
a) loosen the screw ➊
b) turn the draw off lever ➋ counterclockwise so
that the remaining thread in the needle gets
longer.
2. Stitching
Follow the above-mentioned procedure in
cases some stitches skip during sewing
process. Turn the draw off lever ➋
counterclockwise. It enlarges the loops at
loopers, which then catches the stitches better.

home position, the clamping foot should not be higher than the
needle tip.
2. Adjustment of the clamping foot directing at the centre of the needle
