Adjustment of oil amount for the face plate components.
Amount of lubricating oil supplied to the face plate components such as needle bar crank ❷ is ad-
justable by turning adjusting pin ❶ : bring the dot mark ❸ engraved on the adjusting pin close to
needle bar crank ❷ to minimize or farthest from the needle bar crank ❷ to maximize the amount
of oil maximize the amount of oil.
(Caution) The oil amount does not change immediately after adjustment, so have this in mind
when adjusting the oil amount.

Sample showing the appropriate amount of oil supplied to the face plate parts
1) The state given in the figure shows the appropriate amount of oil (oil splashes). It is necessary
to finely adjust the amount of oil in accordance with the sewing processes. However, do not ex-
cessively increase/decrease the amount of oil in the hook. (If the amount of oil is too small, the
face plate parts will be hot or seize. If the amount of oil is too much, the sewing product may be
stained with oil.)
2) Adjust the amount of oil in the hook so that the oil amount (oil splashes) should not change
while checking the oil amount three times (on the three sheets of paper).
