・ Stopping the needle bar
When conversion lever ❶ is moved to L position,
the left needle bar stops. When it is moved to R
position, the right needle bar stops.

Press conversion fixing lever ❷ . Conversion
lever ❶ returns to the 0 (zero) position to
bring the sewing machine back to the 2-nee-
dle sewing mode.

・ Relation between the bending angle and
the stitch pitch
To carry out the corner stitching with accu-
racy, determine the stitch pitch against the
"Quick reference chart according to gauge". It
is however recommended to finally determine
the stitch pitch by actually carrying out the
corner stitching.
(Example)
To determine the number of stitches to sew a cor-
ner portion of material with a bending angle of 90
° and stitch pitch of 1.6 mm using a 3/16" gauge,
follow the cells along the row of heading "angle
90 °" to the right on the "Quick reference chart
according to gauge" to find the cell "1.6". Then,
follow the cells along the column "1.6" upward to
find the cell "3". Then, you will find the number of
stitches is "3".
・ In the case of turning angle of 40 degrees or less, thread may remain on the wrong side
of material due to inadequate thread take-up amount of the bobbin thread slack preven -
tion spring.
・ Before carrying out the separately-driven needle bar changeover operation, stop the
sewing machine once.
(The sewing machine failure can be caused by carrying out the separately-driven needle
bar changeover operation while the sewing machine is running at a speed of 1000 sti/
min or more.)
・ If the sewing machine is used, with one of its two needles disabled, in substitution of
the 1-needle sewing machine, the sewing machine may fail. If you want to carry out
sewing work using one needle of the sewing machine, it is necessary to remove one of
its two needles and enable both needle bars to operate.
