About this machine
The JUKI LS-1340 is the standard-hook base model in the LS-1340 cylinder-bed unison-feed series. It runs up to 2,000 stitches per minute, uses 135x17 needles in the documented Nm100-Nm180 range and differs from the LS-1341 by using a standard-capacity vertical-axis hook and a single-tension mechanism.
The standard hook is the key LS-1340 distinction
JUKI's model table assigns the LS-1340 a vertical-axis standard hook. The LS-1341 moves to the 1.6-fold-capacity hook, while LS-1342 variants add the small-article gauge.
One tension unit, not two
JUKI specifically notes that the LS-1340 uses a single-tension mechanism. The rest of the series is described with the newer double-tension arrangement for thick thread and higher thread tensions.
