3-11-2. How to confirm the amount of oil (oil splashes)
Amount of oil (oil splashes) confirmation paper
Approx. 70 mm
* Use any paper available regardless of
the material.
* When carrying out the procedure described below in 2), confirm the state that the needle thread
from the thread take-up lever to the needle and the bobbin thread are removed, the presser foot is
lifted and the slide plate is removed. At this time, take extreme caution not to allow your fingers to
come in contact with the hook.
1) If the machine has not been sufficiently warmed up for operation, make the machine run idle for approxi-
mately three minutes. (Moderate intermittent operation)
2) Place the amount of oil (oil splashes) confirmation paper under the hook while the sewing machine is in
operation.
3) Confirm that oil exists in the oil tank.
4) Confirmation of the amount of oil should be completed in five seconds. (Check the period of time with a
watch.)
3-11-3. Sample showing the appropriate amount of oil
Appropriate amount of oil (small)
Splashes of oil from the hook
• DDL-8000A-*MS : 0.5 to 1 mm
• DDL-8000A-*SH,*SJ : 1 to 3 mm
1) The state given in the figure above 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 excessively in-
crease/decrease the amount of oil in the hook. (If the amount of oil is too small, the hook will be seized (the
hook will be hot). If the amount of oil is too much, the sewing product may be stained with oil.)
2) Check the oil amount (oil splashes) three times (on the three sheets of paper), and adjust so that it should
not change.
