10.02 Cleaning the machine
The required cleaning cycle for the machine depends on the following factors:
 Single or multi-shift operation
 Dust formation caused by the workpieces
Optimal cleaning instructions can therefore only be determined on a case-by-case basis.
Disconnect the machine from the electricity mains for all cleaning work by
shutting off the main switch or removing the mains plug! Risk of injury due to
accidental machine start-up!
The following tasks are recommended
during single shift operation to avoid
operational errors:
Clean the hook area
 Clean the hook area with a brush
Clean the hook
 Open the hook area cover.
 Bring the needle bar to the top position.
 Remove the bobbin case sewing head

 Turn the handwheel until the tip of the
bobbin case 2 has penetrated approx.
5 mm into the groove of the hook race.

 Make sure that the horn 3 engages in the groove of the stitch plate when inserting the
bobbin case.
