Lower thread counter
INSTRUCTION MANUAL CD
5-6. Using the lower thread counter
The graphic display lights and a buzzer sounds before the bobbin thread runs out, so that the operator can concentrate on the job with confidence.
Maximum presser foot lift amount 16 mm
The knee lifter and the needle up stop (reverse rotation) function together provide 16 mm of space underneath the presser foot. This makes it much easier to insert and remove heavy material without it getting caught on the needle.
(Contact the place of purchase.)
Selectable starting speed
The sewing speed at the sewing start can be selected in accordance with the treadle depression amount. You can set the speed according to the preferences of the operator.
(Contact the place of purchase.)
Easy setting of sewing speed from operation panel

The sewing speed can be easily set by the sewing speed control keys.
Condensed stitching
INSTRUCTION MANUAL CD 9-3. Sewing condensed stitches
This feature is ideal for use when sewing thin materials that can easily pucker when reverse stitches are sewn. Condensed stitches have a smaller sewing pitch and they help prevent fraying.

Floating presser foot for easy handling
INSTRUCTION MANUAL CD
13-11. Adjusting the presser foot floating amount
A micro-adjustable type floating presser foot is equipped as standard. This device is ideal for controlling presser foot floating in materials that stretch easily and materials with long pile. It prevents seam slippage and also prevents damage to the material. In addition, three-dimensional articles with irregular curves can also be handled with ease.
