Easy operation
Easy positioning
• The presser foot lifter is driven by a pulse motor, so that the height can be adjusted
as desired (standard function) for when the pedal is at the neutral position and
when it is depressed forward (two stages) and backward. This makes insertion and
removal of the material easier and reduces working fatigue.
• The presser foot rises only by the height necessary, so that the time needed for it to
rise and drop can be shortened.

Gives perfect sewing finishes
Stable zigzag seams even at high speed
A new needle zigzag mechanism (patent pending) reduces the effect of
vibration from upper shaft rotation on the needle bar, so that stable and
accurate needle zigzagging is obtained even at high speeds. When
sewing speed has been changed, a knife is not used to trim the thread.
The cutter space does not change, further making sure that the finish is
attractive.
Adjustment of zigzag width balance is possible
The left and right stitch width ratio for buttonholes can be set on the operation
panel.
Under lay
Up to four pattern can be combined and sewn together.
Rectangle
Saw shape
• Effective for preventing material from stretching.
• This is useful for preventing dimples from forming during bar
tacking.
• If the seam is hidden and the width seems small, sew 2-3
underlays to make the material look more voluminous.
• It is also effective for strengthening the buttonholes to stop
the seam from unravelling, which can often happen with
materials with coarse weaves.
• Because the material can be move slightly up to five times,
the seam flexibility is maintained and the button hole strength
can also be increased.
Sew together
Zigzag
• If the cutter has operated before the seam has been formed,
the hole made by the cutter is sewn up beforehand.
• The pile of fluffy fabric is pressed down before sewing, so
that the buttonhole finish looks more attractive.
• Effective for preventing seam from unravelling.
Selectable cutter operation
The operation of the cutter can be set to one of four timings (front knife, center
knife, rear knife and front + center knife). When the front knife setting is used, the
rough edges are hemmed by the buttonhole stitches after cutting, thus providing
a more attractive finish. When “Feeding when cutter operating” is set, only the
feed mechanism operates after sewing and the cutter moves to the specified
position, so that the button hole can be cut right up to the front backtacking.

Two-cycle sewing
When set to two-cycle cross sewing, the zigzag stitches sewn
during the first and second cycles do not overlap with each other,
so that the sewing pitch appears finer and the finish looks even
more attractive.
Prevents dimples at the rear tack
Selectable rear tack vector shape prevents dimples at the rear tack
section when not using an underlay.

PD-8000 Programmer
You can set parameters simply by selecting an icon, so that sewing data
can be created easily. In addition, the programmer can be disconnected
from one sewing machine and connected to another one, so that program
data can be copied between machines. A single programmer can thus be
used to create programs for several machines.
Product specifications are subject to change for improvement without notice. Please read instruction manual before using the machine for safety operation.
