Switch off machine electrically!
3.2.1
After removing the head cover and the thread tension adjustment button, the
needle lever must be turned down so far, that the eccentric bolt (1) can be
reached with a screw driver through the hole provided in the head. Once the nut
(6) has been slackened, the needle lever path is corrected by turning the bolt
(at the rear).
In this case, the distance between the shuttle point (for normal loop stroke and
position above the centre of the needle) and the end of the needle eye turned
towards it, must be 1.8 ±0.2 mm.
Setting the needle lever path (Fig. 1)
3.2.2
The needle lever is set so that the needle is located centrally in relation to the
needle plate.
Adjustment can only be carried out by moving the bearing bushes (3) and (2) in
the head, to the side (by tapping gently).
