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.
4. Supporting the paper with hand, run the sew-
ing machine by five cycles using the standard
pattern (3,600 sti/min) and check the splash-
ing oil quantity.
In the case the oil quantity is too much
even after the oil controlling screw is
fully tightened, remove the hook shaft
coupling ❺ and cut off the excess of
oil wick ❻ .
