* The adequate oil quantity is achieved when the
oil spots are made on paper within a range of 2 to
5 mm in width (oil spots should not be in the form
of lines).
3) How to check the hook oil quantity
1. In preparation for checking the hook oil quan-
tity, cut a sheet of paper to make a piece of
paper size of which is approximately 40 mm x
100 mm.
2. After the adjustment of the oil quantity, start
the sewing machine at a high speed (3,600
sti/min) by 100 times or more.
3. Insert the piece of paper prepared in Step 1
into the clearance provided between the hook
cover and the bed base so that it is placed
near the underside of the hook.
As a guide, insert the paper until it comes in
contact with the hook oil shield.

5. Adjusting the bobbin thread tension
Adjust the bobbin thread tension as given below when the bobbin thread is pulled up at the position where
thread slit of bobbin case comes up.
Purl stitch0.05 to 0.15N
Whip stitch0.15 to 0.3N
Turning tension adjust screw clockwise will increase bobbin thread tension, and turning it counterclockwise will decrease the tension.
Adjust the bobbin thread tension to lower for synthetic lament thread, and to higher for spun thread. The
thread tension is higher by approximately 0.05N when the bobbin case is set to the hook since idle-prevention spring is provided.
When bobbin thread tension is adjusted, check the needle thread tension setting of the
memory switch. (Refer to "V-22. Memory switch data list" p.55.)
To such an extent that bobbin case quietly comes down when holding
thread end coming from bobbin case and shaking it quietly up and down.
To such an extent that bobbin case barely comes down when holding
thread end coming from bobbin case and shaking it somewhat strongly.

position is reached, and it will click.
1. If the bobbin case is out of the predetermined position, it can jump out
from the hook to cause the needle
thread to tangle on the hook shaft.
Check to be sure that the bobbin
case is properly installed in the correct position.
2. There is a difference in the shape of
bobbin case between the standard
hook and the dry one. They have
nothing in common with each other.
