The gap between the shuttle tip and a 90 needle must max. 0.2 mm.
Setting the shuttle in relation to the needle (Fig. 5)
If it is necessary to adjust the shuttle, then this is done by slackening the
cylinder head screw (1) and turning the eccentric bushing (2).

3.4.3
If a thread has become jammed between the bobbin case and shuttle, the
bobbin case must be removed, otherwise the machine will be slowed down.
This will entail removing the shuttle - see point “
Removing and fitting the bobbin case (Fig. 5)
mounting the looper (Fig. 3 + Fig. 4)”.
Once the screws (1) have been slacked, the shuttle cover (3) can be removed.
The bobbin case on the bobbin retaining flap (2) is then turned to position C
whereupon it is pulled out of the shuttle.
When replacing, ensure that the bobbin retaining flap (2) points in the direction
of the shuttle point (C).
