(39) Applying the exclusive grease
*
Exclusive grease (23640204) is applied to the portions other than the lubricating portions to which
lubrication is necessary
It is not necessary to add grease to the portions when the machine is generally used. However, when
the machine is used under the severe conditions, it is effective to periodically fill up the exclusive grease
(approximately once or twice a year).
[Note when applying grease]
1) Needle bar metal of DS and DU heads
Needle bar metals are set to the upper and lower parts of the needle bar support base and there is a
grease groove inside each metal (No. 55). Draw the needle bar and fill up the exclusive grease to the
groove.
When newly filling up the grease, make the sewing machine run idle for 10 seconds each to discharge
excess grease which occurs at this time and wipe the grease. Perform this operation several times and
use the sewing machine when the grease does not occur.
