17. Spreader plate
Caution: Danger of injury !
Turnthemainswitchoff.
Adjust the spreader plate only with the machine switched off.
Standard checking
The opening and closing of the spreaders is effected by the alternate
motion of the spreader plate 2.
When the needle bar is in the bottom dead centre for the right stitch,
the distance between spreader plate 2 and spreader leg 1 must be
exactly the same as that between spreader plate 2 and spreader
leg 3 (dimension X1 = dimension X2), when the needle is in the bottom
dead centre for the left stitch.
Correction
–
Loosen the screws at the clamping rings 4 and 6.
–
Move the clamping rings in such a way that the distance between
spreader plate and spreader legs is equal.
–
Tighten the screws at the clamping rings 4 and 6.
Note
The washer 5 must still be freely movable after tightening.
