Troubles and corrective measures (sewing conditions)

Trouble
(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.
1. The needle
thread slips off
(4) Needle thread tension at 1
at the start of
high.
bar-tacking
(5) Thread clamp is unstable(material is
apt to be expanded.Thread is hard to
slide,thread is thick,etc.)
(6) Pitch at 1
(1) The shuttle or the driver has scratches.
(2) The needle hole guide has scratches.
(3) The needle strikes the work clamp foot.
2. Thread
(4) Fibrous dust is in the groove of the
often breaks or
shuttle race.
synthetic fiber
(5) The needle thread tension is too high.
thread splits
(6) The synthetic fiber thread take-up
finely
spring is too high.
(7) The synthetic fiber thread melts due to
heat generated on the needle.

Corrective measures

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

Decrease the number of rotation at 1
sewing start.(Extent of 600to 1000rpm)

Increase the number of stitches of thread clamp to
3to 4stitches.

st
Make the pitch at 1 stitch longer.

Decrease the needle thread tension at 1

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.
