Before Using Your Sewing Machine
Before using your sewing machine for the first time, place a
waste fabric under the presser foot and run the machine
with thread for a few minutes. Wipe away any oil which may
appear.
For Y our Safety
* While in operation, always keep your eyes on the sewing
area. Do not touch any moving parts, such as the thread
take-up lever, handwheel or needle.
* Always turn off the power switch and unplug from the
power supply:
- When leaving the machine unattended
- When attaching or removing any parts
- When cleaning the machine
* Do not place anything on the foot control, when not
sewing.
Controlling Sewing Speed
Sewing speed can be varied by the foot control.
The harder you press on the foot control, the faster the
machine runs.

Insert a new needle into the needle clamp with the
flat side to the rear. When inserting the needle into the
needle clamp , push it up as far as it goes. Tighten
the needle clamp screw firmly by turning it clockwise.
3
To see if the needle is good, place the flat side of the
needle onto something flat (e.g needle plate or glass).
The gap between the needle and the flat surface should
be consistent. Never use a bent or blunt needle.
A damaged needle can cause permanent snags or runs
in knits, fine silks and silk-like fabrics.

Selecting Needle and Fabric
NH1722S Instruction Manual
www.toews.com
1722S Owners Manual/ User Guide
For general sewing, use needle sizes 11 or 14. A fine thread and needle should be
used for sewing lightweight fabrics, so the fabric will not be marred. Heavy fabrics
require a needle large enough to pierce the fabric without fraying the needle thread.
In the needle set, there is one each of sizes 11, 14, 16, and 18, and a blue needle.
Use the blue needle to eliminate skipped stitches when sewing knits and synthetic
fabrics.
Special needles should be used on certain fabrics. A denim needle with a sharp tip
effectively pierces dense fabrics such as denim and canvas. For topstitching, a
special topstitching needle with a larger eye, accommodates heavier weight thread.
Leather needles punch small holes in leather and suede, allowing the thread to
follow through the hole.
Check your needles frequently for rough or blunt tips. Snags and runs in knits, fine
silks and silk-like fabrics are permanent, and are often caused by damaged
needles.
Always purchase good quality thread. It should be strong, smooth and consistent in
its thickness.

If you look at the top and bottom of a seam, notice that
there are no gaps. Each stitch is smooth and even.
When adjusting the needle thread tension, the higher the
number, the tighter the needle thread tension.
Results depend on:

NOTE:
When using the straight stitch foot, make sure to set the

and stitch width at “5”. Otherwise the needle may strike
the sewing foot and could possibly break.
• Starting to sew
Raise the presser foot and position the fabric next to a
seam guide line on the needle plate (5/8˝ [1.6 cm] is most
common). Lower the needle to the point where you want
to start. Lower the presser foot and pull the threads
toward the back. Depress the foot control. Gently guide
the fabric along a seam guide line letting the fabric feed
naturally.
• Finishing sewing
To fasten the ends of a seam, press the reverse stitch
control and sew several reverse stitches. Raise the
presser foot. Remove the fabric, draw the threads to the
back and cut them with the thread cutter. The threads are
now the proper length to begin sewing the next seam.
CAUTION: Do not place fingers near the presser foot
when guiding fabric, or the needle clamp screw may
strike and injure your fingers.
Use the Seam Guides

apart, and are engraved at 3/8˝, 4/8˝, 5/8˝ and 6/8˝. The
lines in millimeters are 5 mm apart, and are engraved at 10
mm, 15 mm and 20 mm.
Turn a Square Corner
1
Cornering guide
When sewing with fabric edge at 5/8" seam guide, to turn a
square corner so that sewing continues at the same
distance from edge:
1. Stop stitching when the front edge of the fabric reaches
the cornering guide lines.
2. Lower the needle by turning the handwheel
counterclockwise.
3. Raise the presser foot and turn the fabric
counterclockwise 90°.
4. Lower the presser foot and begin stitching in the new
direction.

used when making swim wear, ski pants and other
garments which require stretch.
• Starting to sew
Place raw edge of fabric to the “ left ” of the needle as
shown. Sew in a manner so that the needle pierces the
fabric very close to the outside edge. Or place the fabric
to allow a 5/8” (1.6 cm) seam, then trim seam allowance.
Raw or worn edges of older garments can be overcasted
to prevent further raveling.
NOTE:Use a #11 blue stretch needle, which effectively
prevents skipped stitching.

Smocking is a delicate decorative treatment used on

Choose a soft and lightweight fabric such as batiste,
gingham or challis. Cut the fabric three times wider than
the projected width. Set stitch length at “4” and sew rows
of straight stitches 3/8" (1.0 cm) apart across the area to
be smocked.
Knot the threads along one edge . From the other
edge, pull the bobbin threads (bottom threads) to
distribute the gathers evenly and secure the threads.
Sew the smocking stitches between the gathered rows.
Remove the straight stitches by pulling them out.
