Gripping the shaft " 13 " by hand, turn it counterclockwise until
the pin " 1 " of the reverse plate is completely in the groove. In
this position the shaft is blocked and cannot move any further.
To check the above adjustment 3, proceed as follows:
Slightly tighten the two screws " 8 " of the collar " 9 ".
Press upon the reverse push button. It must not move. If this
is not the case, repeat adjustment 3 as explained above.
Slightly tighten the two screws " 8 " which hold the collar " 9 "
on the shaft A/13.
Place two thicknesses of material under the presser foot and
lower
the presser foot.
Leave the stitch length regulating knob at zero (0), let the
machine
ne run and check whether the material under the presser foot
is
moving.
If the material is not moving, firmly tighten the two screw " 8 "
In collar " 9 " on the shaft A/13.
If the material moves, proceed as follows:
Slightly loosen (so that there is still some friction) the two
screws " 8 " in the collar " 9 ".
If the material under the presser foot moves backward, push
the shaft in its axial direction toward the rear wall, being care
full not to turn the shaft.
If the material moves forward, push the shaft in its axial direction
toward the front wall.
Repeat this procedure, if necessary, until the material does not
move at position " 0 " (zero) of the stitch length regulating knob.
Securely tighten the two screws " 8 " in collar " 9 " of shaft " 13 ".
To make sure that the shaft A/13 did not turn during this adjust-
ment, try to press the reverse push button which must not move
at all.
If the button moves, repeat adjustment 3.
