- Remove the head cover and remove any
lint or other contaminants that may be in this area,
Figure 5. This can be done using a
small brush, a rag or compressed air. Before replacing the head cover,
it is recommended to place a few drops of oil on the needle bar and
needle bar connection in case all of the oil has been removed.
- Check the looper thread take-up area for
an accumulation of lint or thread and remove as required,
Figure 6. Also, check the
looper thread take-up cam and cast off plate for nicks, burrs or wear,
and repair or replace as needed.
- Check the various thread contact
surfaces such as eyelets, tension discs, needles and thread stand for
nicks, burrs or worn parts and repair or replace as needed,
Figure 7.
- After the above maintenance has been
performed, make sure the oil plug and covers have been replaced and
place the machine on a level surface and fill the main reservoir,
Figure 8, until the oil is visible
between the two red lines of the oil gauge located beneath the cylinder
arm, Figure 9.
- Once the machine has been properly
filled with oil it is recommended to run the machine slowly for a few
minutes to let the oil flow to the critical areas.
