1. At this time, leave a space of 0.5 to 1 mm between the
thread draw-out wire and the top surface of the thread
take-up thread guide A.
2. After the completion of adjustment, be sure to operate
the thread draw-out wire and check that the thread draw-
out wire does not come in contact with the thread take-
up thread guide A.

describred in the function setting list.
1) When top end
3
of the gauge of oil amount indicating window
1
comes down to the lower marker line, fill JUKI Defrix Oil No.
1 from oil inlet
4
up to the marker line of oil tank
2
with the
sewing machine tilted.
Even when the gauge comes down to the lower marker line,
oil in the oil tank remains for safety. It is recommended to fill oil
as soon as possible.
™
The amount of oil to be filled is approximately 150 cc.
2) For the adjustment of the amount of oil in the hook, check the
amount in the hook after making the sewing machine run idle
continually for approximately 30 seconds and stabilizing the
amount of oil.
(Caution)
1. When using the sewing machine with it tilted to the front,
the state of the oil amount indicating window is not
useful. So, be careful.
2. If the oil amount adjustment screw is excessively
loosened, the O ring comes off and oil spouts out. Do
not loosen it more than 5 turns.
3. The oil pipe which has been removed once is likely to
easily come off. As a result, oil leakage may be caused.
Be sure to replace the pipe with a new one when it is
removed.
4. When assembling the respective pipes, take care not to
allow you to come in contact with the moving parts.
™
If the stroke of the thread draw-
out wire is insufficient, the length
of the needle thread remaining
after thread trimming will be
reduced resulting in stitch
skipping and slip-off of the
thread at the start of sewing.
If the stroke of the thread draw-
out wire is excessive, thread
breakage will occur at the start
of sewing.
