of the needle bar connecting section.

[DDL-9000B-SS, SH only]
3. Confirm that the needle bar
keeps an exact contact with the oil
wick
in the position 5mm below the needle bar upper bushing
.
If there is no contact, correct it by means of the oil wick support
plate
.
(Cautions) Apply a piece of paper to the oil wick
and confirm
whether it is wet with oil.
o Grease is not required for the
presser bar
.
If grease is applied, contamination
like black ink is caused by the
presser bar bushing
and the
material cloth may be stained.
o This can be a cause of seizure
between the needle bar
and the
needle bar upper bushing
.
