Needle Height - Bernina B 590 Service And Maintenance Manual

5.5.5 Needle height

Check:
• Remove needle.
• Attach distance gauge a (030883.50.03 silver-coloured with 3 punctures).
• Lower the feed-dog.
• Select 'centre' needle position.
• Switch machine off if required.
• Place distance plate b (730475.51.00) under distance gauge a on stitch plate.
• Needle bar BDC represents 'target' c on distance plate b level 2.
Note:
If the position of the gauge b deviates from value c = 2, the needle stop pin must be replaced. This applies to
all 5Series machines with basting device (VIO).
Adjustment:
• Remove distance gauge a.
• Remove needle clamp (see 4.3.15)
• Replacing the needle stop pin d (T6) allows for modification of the height.
• Needle stop pins are available in 8 different diameters (see table).
• Select the appropriate needle stop pin d to correct any deviation from the target.
• Refit needle clamp (see 4.2.15).
Note:
• The height difference between levels corresponds to the diameter difference of the next larger or
smaller needle stop pin d.
• If the needle requires lifting = use smaller diameter.
• If the needle requires lowering = use larger diameter.
