For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following
SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the
SAFETY PRECAUTIONS
includes items which
are not contained in the speci¿cations of your product.
The risk indications are classi¿ed into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.

14. HEIGHT OF THE PRESSER BAR
1
After replacing a presser foot or when the presser bar height is
changed, adjust the presser bar position as follows;
1. Loosen the clamp screw
1
of the presser bar guide bracket by in-
serting a screw driver through the adjusting hole on the face plate,
2. Retighten the screw
1
securely after positioning the presser bar.
15. LENGTH OF THE THREAD TAKEN UP BY THE THREAD TAKE-UP LEVER
In order to always produce perfect stitches, it is advisable to adjust the
length of the thread taken up by the thread take-up lever according to
each sewing condition like the type of material and the stitch length.
1. When sewing a heavy weight material slide the thread guide up-
ward to shorten the thread.
2. When sewing a light weight material, slide the thread guide down-
ward to lengthen the thread. This adjustment is also effective to
prevent stitch-skipping.
WARNING :
To avoid possible personal injury due to abrupt start of the machine, turn off the power to the machine and check to be sure that the
motor has totally stopped rotating in prior.
1) Use the 3-phase 200W AC clutch motor.
2) Use an M type V belt.
3) The following table shows the relationship among the motor pulley and the sewing speed.
