Calculation table

This table is meant to show how many hours are required for a maintenance message to be displayed as a
function of the SPM (stitches per minute) speed.
For example:

1'000

9.2.4 Implementation of the maintenance intervals

A servicing message appears on reaching the 3rd interval (9 million stitches) each time the machine is
switched on.
The message only disappears after resetting to zero by the technician making a service entry in the Service
Program.

9.3 Maintenance intervals

To calculate the maintenance intervals, an average sewing or embroidering speed of about 650 spm is
assumed.

9.3.1 Cleaning- and service-stitch reset

• Service entries must be made by the technician in the Service Program after maintenance or repair
work. If not, the maintenance stitches will not reset to zero.
• The same holds true for the cleaning-stitch reset.
