3.2.2 Setting the needle stroke (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. 1 mm to the right hand edge of the large looper
finger, the point of the large looper finger being above the needle center (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 with an allan key. The ball bolt
(2) can be adjusted at the rear head side with 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.
