Remount the needle plate in reversed order.
Remounting the needle plate
3.1.3
The theoretical needle radius of 43.6 mm should be 0.01 - 0.04 mm smaller at
the needle slide plate; in other words, a checked needle is raised by
0.01 - 0.04 mm.
This is verified with a dial gauge.
Setting the needle plate (Fig. 1)
If this setting is correct, there should automatically be a space of
0.25 - 0.35 mm between the needle and the needle plate radius (also verify with
a dial gauge).
Deviations from this will considerably detract from the sewing result and may, in
addition, result in damage or premature wear of the sewing tools.
By slackening the threaded pin (4) on the left and right in the head, and
slackening the fixing screws (5), the needle plate may be pushed carefully
upwards or down, towards the needle.
Warning!
When tightening the screws, check that the needle plate is
horizontal.
