Set the needle stroke in a way that at a loop stroke of 2.8 +0.3 mm the left side
of the needle eye has a distance of approx. 1 mm to the right hand edge of the
large looper finger, the point of the large looper finger being above the needle
center (
Setting the needle stroke (Fig. 7)
Fig. 6).
To adjust the stroke turn the main shaft until screw (1) is in horizontal position
under the boring in the upper head side. Release the screw (Allan key size 4);
ball bolt (2) can be adjusted through the rear head side (remove the oval cover)
by means of a slotted screwdriver. Insert the ball bolt in horizontal position so
that the slot of the
∅
6 bolt is placed vertically under the
∅
7 bolt.
Clockwise turning means a larger needle stroke, anticlockwise turning results in
a smaller needle stroke. The distance ball bolt to needle shaft is
2 ±0.5 mm. Readjust the needle lever as per “3.2.1 Mounting” after adjusting
the needle stroke.
Tighten screw (1). Check looper and needle movements through turning the
main shaft by means of the handwheel.
