New Adjusting Tool for the
L450/L450 Available
Good news, we have now received the
final adjusting tool for the L450/L460.
We have made many changes to the
different looper and overall adjustments
to increase the overall performance of
the machine, and to eliminate skipping
stitches with certain fabrics, threads and
machine sewing settings.
Please compare the gauges next to each
other and see the different measurements.

Please dispose of the original gauge #
22850 and order the new gauge # 22948,
the tension calibration reset gauge #
22844. The service manual is available
on Infogate under US-65564-5 or
click here.
It is most important that all (original
and latest machines are being adjusted
using ONLY the new final gauge
Using the original gauge for any adjustments
causes major issues with current
machines and does not resolve skipping
issues with original machines
