3.3.2 Setting the needle lever (Fig. 4 and Fig. 7)
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. 2 ±0.5 mm to the right hand edge of the large
looper finger, being the point of the large looper finger above needle center (Fig. 7).
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 (9) (Allan key size 4), ball bolt (10) can be adjusted through the rear
head side (remove the oval cover) by means of a slotted screwdriver (Fig. 4).
Insert the ball bolt in horizontal position so that the slot of the Ø6 bolt is placed
vertically under the Ø7 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 “3.3.1 Mounting the needle lever (Fig. 5)” after
adjusting the needle stroke.
Tighten screw (1).
