Fill the machine with appropriate
lubricate oil (Singer Oil) by remov-
ing the cap as indicated on Figure 6,
until the oil level is between the
marks of the oil level sight window.
Add oil when the oil surface
reaches or goes below the lower
mark ‘ L’ .
Check if the oil is circulating prop-
erly by observing the oil sight
window, as shown on Figure 7.
Fill the device with silicone oil
before it is too low in order to
prevent needle thread breakage
and fabric damage, as shown on
Figure 8.

according to the fabric
type and thickness,
sewing thread, seam
width, stitch length and
others. Therefore the
pressure of the tension
nuts or thread guides
must be adjusted in
each individual case.

Differential Feed
Rate Adjustment
The differential feed ratio is the ra-
tio of movements between the main
feed dog and differential feed dog.
When the movement of main feed
dog is bigger than the differential
feed dog, the fabric is stretched at
sewing. Otherwise the fabric will
shrink.
Loosen nut ‘1’ of Figure 26 and
move the lever ‘2’ up or down to
obtain the correct differential ratio.
Retighten the nut ‘1’.
