lifted and the slide plate is removed. At this time, take extreme caution not to allow your ngers to
come in contact with the hook.
1) If the machine has not been suciently 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) conrmation paper under the hook while the sewing machine is in
operation.
3) Conrm that oil exists in the oil tank.
4) Conrmation of the amount of oil should be completed in ve seconds. (Check the period of time with a
watch.)

• DDL-8000A-PSH : 1 to 3 mm
• DDL-8000A-PMS : 1 to 1.5 mm
• DDL-8000A-PSH : 2 to 4 mm
Splashes of oil from the hook
1) The state given in the gure above shows the appropriate amount of oil (oil splashes). It is necessary to
nely 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.)

3-12. Adjusting the thread take-up spring and the thread take-up stroke
(1) Adjusting the stroke of thread take-up spring ❶
1) Loosen setscrew ❷.
2) Turn tension post ❸ clockwise (in direction A), the stroke of the thread take-up spring will be increased,
and turn the post ❸ counterclockwise (in direction B), the stroke will be decreased.
(2) Adjusting the pressure of thread take-up spring ❶
1) Loosen setscrew ❷, and remove thread tension (asm.) ❺.
2) Loosen tension post setscrew ❹.
3) Turn tension post ❸ clockwise (in direction A), the pressure will be increased, and turn the post ❸ coun-
terclockwise (in direction B), the pressure will be decreased.
(3) Adjusting the thread take-up stroke
1) When sewing heavy-weight materials, move thread guide ❽ to the left (in direction C) to increase the
length of thread pulled out by the thread take-up.
2) When sewing light-weight materials, move thread guide ❽ to the right (in direction D) to decrease the
length of thread pulled out by the thread take-up.
* Standard state of the thread guide
The standard distance between the right end face of thread guide and the screw head is as follows:
To check how the thread take-up spring works, draw out the needle thread in direction
F after
having adjusted the thread take-up spring pressure to check whether the thread take-up spring
exerts force to the thread up to the last moment (state
G) just before the thread comes out
from E. If the spring fails to exert force to the spring until the last moment (state
H), decrease
the thread take-up spring pressure. In addition, the stroke of the thread take-up spring is exces-
sively small, the spring does not work properly. For the general fabrics, a stroke of 10 to 13 mm
is proper.
