A large variety of stitches for clothing construction, quilting, heirloom, crafts,
home decorating and decorative sewing.
6 Fully Automatic
1-step Buttonholes
Buttonhole sewing is a one-step simple process, providing reliable results
every time. Each side of the buttonhole is sewn in the same direction,
creating beautifully balanced buttonholes.
3-Step Infinite
Length Bar-Tack
Buttonholes
There are no size limitations with this buttonhole. This is ideal when sewing
non-traditional sized buttonholes.
Exclusive
Buttonhole Underplate
This system sandwiches fabric between a lower plate and the foot to ensure
perfect buttonholes on multiple layers of fabric. It makes creating buttonholes
possible in places that conventional buttonhole devices cannot easily reach.
Built-In Alphanumeric
Stitches
Personalize projects by adding a monogram, name or phrase with the built-In
block style alphabet and numeric stitches.
Model 8770

Feature Benefit
LCD Screen The LCD provides clear and easy viewing of stitch patterns including
stitch width and length.
Built-In Stretch Stitches Specially designed stitches that add strength and flexibility to seams,
especially useful when sewing on knitwear and super-stretch fabrics.
Hand-Look Quilt Stitch
This stitch is designed to look like hand sewing for topstitching or
quilting. The Hand-Look Quilt Stitch is especially valuable to quilters,
crafters and heirloom seamstresses.
Adjustable Stitch Length Automatic settings for length can be overridden to personalize length
choice.
Adjustable Stitch Width Automatic settings for width can be overridden to personalize width
choice.
Center Zigzag Taper When tapering with the zigzag stitch, the stitch tapers to the center, not
the left or right. This provides a more attractive look when tapering into
or out from a point.
Automatic Tacking
Stitch Function
Tie-off decorative stitches with just a push of a button. With 4 tiny
tacking stitches the start and end of the pattern is reinforced. This
ensures quality stitching and prevents unraveling.
Automatic Tie-Off Function This function reinforces the start and end of seams for stronger
stitching.
Automatic Reverse
Push the conveniently located Automatic Reverse Button to sew in
reverse and reinforce the stitch.
7mm Stitch Width
Many stitches can be set for a maximum width of 7mm for satin and
decorative stitches.
Programmable Needle
Up and Down Select whether the needle is up or down when the machine stops. It’s
beneficial to have the needle stop in the down position when
appliquéing, quilting or pivoting fabric.

Feature Benefit
Electronic Twin Needle Control Stitches are automatically adjusted for twin needle sewing with just the touch of a button.
13 Needle Positions Needle position can be changed for individual projects like inserting
zippers, cording and topstitching.
20-Space Memory A memory bank holds full names and simple phrases.
Editing Capabilities Easily edit monograms or phrases using the built-in alphabet.
Mirror Image
Stitches can be mirror imaged with just a touch of a button.
Continuous Pattern
Individual stitches can be sewn together as a pattern with just a touch
of the button.
Error Messaging
4 audible and visual warning messages alert the sewer making for
trouble-free sewing.
Pattern Override Memory Select a pattern, override the width and/or length and the machine will
remember those changes for future use.
Sewing Speed With a maximum sewing speed of 750 stitches-per-minute, projects
can be sewn quickly.
Automatic Tension This system ensures stable stitch quality, whatever type of fabric is
being used.
Automatic Presser Foot
Pressure Control The amount of pressure exerted on the fabric by the presser foot
against the feed dogs is automatic. Sew from the lightest weight tricots
to the heaviest denim, without making presser foot adjustments.
Extra-High Presser Foot Lifter Offers more clearance, which is needed when placing multiple layers
of bulky fabric under the presser foot.
Free Arm Provides professional results and easy access to cuffs, collars, pant
hems and other difficult-to-reach areas.

Feature Benefit
Top Loading Jam-Proof
Bobbin System with Clear Cover
This mechanism incorporates a magnet-type vertical axis rotating hook
that ensures smooth, quiet, thread jam-resistant sewing. The bobbin
case floats above the hook, precluding thread jams.
Automatic Bobbin Winding Clutch Needle bar automatically disengages when winding the bobbin, making bobbin winding safer.
6-Segment Feeding System
This is a specially designed feed dog that ensures the fabric is picked
up and supported from the front of the presser foot to the rear. This
makes for much more accurate fabric feeding.
Box Feed
This is a feed dog motion that moves the feed dogs in a box motion,
rather than the historic arc motion. Box motion assures perfect feeding
throughout the entire feed process, as the feed dogs are always in
perfect and equal contact with the fabric and presser foot.
Drop Feed
A conveniently located lever, easily and effortlessly moved, will lower
the feed dogs for free-motion embroidery, monograms and for sewing
buttons.
Heavy Duty Metal Frame
The internal skeleton of the sewing machine. This rigid support holds all
the mechanisms in perfect alignment for perfect, skip-free sewing.
Direct Drive The needle bar is geared straight from the motor, rather than from a
drive bar across the machine. This makes the machine more powerful
and durable.
On Board Storage Have easy access to accessories while sewing.
Snap-On Presser Feet Easily change presser feet without a screwdriver.
Thread Cutter Located on the machine for precise thread cutting, eliminating the extra
step of cutting thread with scissors.

Feature Benefit
Optimum Power Control
A control system that senses when additional power is required to
maintain speed through thick or changing fabric conditions. This feature
is most useful when sewing through multiple (6-8) layers of fabric.
DC Motor Provides instant start up and stop with no casting, for accurate and
precise stitch placement.
Electronic Foot Controller Guarantees consistent sewing speed with no jump starts.
Dust Cover Keeps the sewing machine free of dust and debris while not in use.
