If, after having turned the eccentric support of the gear No.
C85664 clockwise as far as it will go, there is still too much play
between the two gears, replace the worn out gears with new
ones.
The machine is set for straight sewing (the cams have been
removed and the zig-zag stitch lever is set at " O "), but still sews
zig-zag. This may be due to two reasons, namely (Fig. 54):
The zig-zag stitch lever, D 85611 drawn back by spring " A ",
does not contact the eccentric No. 85663 of the lever
No. C 85641.
The lever No. C 85641 is not in its right position.
In the case " a " proceed as follows (Fig. 54):
Test the strength of spring " A ";
Check whether the sector No. 26106 is sliding freely in the
lower channel of the oscillating lever No. A 85606;
Check whether the lever No. D 85611 is moving freely
around its pivot No. 85693.
