Troubles and corrective measures (sewing conditions)
Trouble Cause Corrective measures
1. The needle
thread slips off
at the start of
bar-tacking
(1) Stitches are slipped at the start
(2) The needle thread remaining on the
needle after thread trimming is too short.
(3) The bobbin thread is too short.
(4) Needle thread tension at 1
st
stitch is too
high.
(5) Thread clamp is unstable(material is
apt to be expanded.Thread is hard to
slide,thread is thick,etc.)
(6) Pitch at 1
st
stitch is too small.
 Adjust the clearance between the needle and the
shuttle to 0.05 to 0.1mm.
 Set soft-start sewing at the start of bartacking.
 Correct the thread tension release timing of the
thread tension controller No.2.
 Increase the tension of the thread take-up spring, or
decrease the tension of the thread tension controller
No.1.
 Decrease the tension of the bobbin thread.
 Increase the clearance between the needle hole
guide and the counter knife.
 Decrease the tension at 1
st
stitch.
 Decrease the number of rotation at 1
st
stitch at the
sewing start.(Extent of 600to 1000rpm)
 Increase the number of stitches of thread clamp to
3to 4stitches.
 Make the pitch at 1
st
stitch longer.
 Decrease the needle thread tension at 1
st
stitch.
2. Thread
often breaks or
synthetic fiber
thread splits
finely
(1) The shuttle or the driver has scratches.
(2) The needle hole guide has scratches.
(3) The needle strikes the work clamp foot.
(4) Fibrous dust is in the groove of the
shuttle race.
(5) The needle thread tension is too high.
(6) The synthetic fiber thread take-up
spring is too high.
(7) The synthetic fiber thread melts due to
heat generated on the needle.
 Take it out and remove the scratches using a fine
whetstone or buff.
 Buff or replace it.
 Correct the position of the work clamp foot.
 Take out the shuttle and remove the fibrous dust
from the shuttle race.
 Reduce the needle thread tension.
 Reduce the tension.
 Use silicone oil.
