Brother HE-800A Operation Manual page 2

Easy operation
No need for adjustments such as replacing cutter cams when changing
number of stitches
The cutter vertical movements is driven by a double position solenoid. If not
using a cutter, the cutter operation can be deactivated at the press of a key.
The cutter operates without slowing down the sewing machine, and the cutter
response time is also fast, so that cycle time is reduced and productivity is
increased.
Sub-table provided as standard
It eases the setting of the material and
reduces operator fatigue.
Simple and easy-to-use operation panel
There is a program memo pocket provided on the
back of the panel. This lets the operator keep necessary information such as a
parameter table, program notes and an error code table on hand for easy
reference. The operator can select panel position whichever above or below the
work table.
Purl stitch / Whip stitch
The upper thread tension is controlled by a solenoid, so that setting between
purl stitches and whip stitches can be done simply by selecting them on the
operation panel. Fine adjustments to the upper thread tension are made using a
thread tension nut. The same method that operators have become used to
allows the optimum thread tension to be easily obtained.
Ideal for sewing vertical buttonholes
A large arm pocket allows smooth material setting. Buttonhole sewing is also possible with the machine head
positioned horizontally to the operator, which fully utilizes the large arm pocket.
Quiet operating environment
Adoption of a clutchless mechanism ensures quieter
operating environment and increased durability.
Accurate home position detection
The home position sensor incorporates a non-
optical proximity sensor, so the sensor is not subject
to operating errors from oil or dust, and cleaning oil
and dust from the sensor are also unnecessary.
Gives perfect sewing finishes
Wide sewing range
The thread take-up, rotary hook and thread path mechanisms provide ideal balance, so that attractive
buttonholes can be sewn in a variety of different materials under a variety conditions.
Accurate cutter operation
The cutter vertical movements is driven by a double position solenoid, so that the material is cut more acurately.
Clean finish with no upper thread trailing length
Attractive finishes are obtained with no upper thread trailing at the sewing end. This ensures a stable and
consistent high-quality sewing finish is always obtained.
Better stitches at the sewing start
Adoption of a bobbin presser prevents the bobbin from spinning free when the lower thread is trimmed.
This makes lower thread feeding more stable and produces better stitches at the sewing start. And the
lower thread holding device holds the lower thread at the sewing start to ensure that the thread end is
sewn into the seam properly.
Easy threading
The needle bar can be moved to the right as a matter
of course, and this makes threading much easier.
