Important Safety Instructions

Grounding Methods

GROUNDING INSTRUCTIONS

This product must be grounded. In the event of malfunction or breakdown, grounding provides path of

least resistance for electric current to reduce the risk of electric shock. This product is equipped with a
cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into

an appropriate outlet that is properly installed and grounded in accordance with all local codes and
ordinances.

DANGER - Improper connection of the equipment-grounding conductor can result in a risk of electric

shock. The conductor with insulation having an outer surface that is green with or without yellow

stripes is the equipment-grounding conductor. If repair or replacement of the cord or plug is necessary,
do not connect the equipment-grounding conductor to a live terminal. Check with a qualied electrician

or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether
the product is properly grounded.

Do not modify the plug provided with the product - if it will not t the outlet, have a proper outlet
installed by a qualied electrician.

This product is for use on a nominal 120 V circuit, and has a grounding plug that looks like the plug
illustrated in sketch A in Figure 61.1. A temporary adaptor, which looks like the adaptor illustrated in
sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a
properly grounded outlet is not available. The temporary adaptor should be used only until a properly

grounded outlet can be installed by a qualied electrician. The green colored rigid ear, lug, and the like,

extending from the adaptor must be connected to a permanent ground such as a properly grounded
outlet box cover. Whenever the adaptor is used, it must be held in place by the metal screw.

A qualied electrician should be consulted if there is any doubt as to whether an outlet box is properly

grounded.

It is very important to make sure that the bobbin tension is properly set rst, see page
16 for directions on setting the bobbin tension. As long as you have your bobbin tension correct,

you should be able to x the tension by adjusting only the top tension. If you are unable to x you
tension by only adjusting the top tension you may need to re-adjust the bobbin tension.

14

Adjusting Thread Tension

Note: The thread tension will need to be adjusted

anytime the thread is changed. Follow the process

below to adjust the thread tension for the thread you
have selected. See page 30 for more information about

properly tensioning your thread.

1. Set the bobbin case, with the bobbin inside, in your hand on

its side and pull up on the thread. The thread should pull the
bobbin case vertical and the thread should ow out of the bob­bin without lifting the bobbin off of your hand. If the bobbin pulls
out of your hand, the tension is too tight and will need to be

loosened. If the thread ows out of the bobbin on its side but

does not pull the bobbin vertical the tension is too loose and will
need to be tightened.

2. To adjust the bobbin tension, locate the larger of the two

screws on the bobbin case. Tighten the tension in minute ad-

justments by twisting the large screw to the right or clockwise.

To loosen, twist the large screw to the left or counterclockwise
minutely.

3. Adjust the top thread tension after the bobbin tension is es­tablished. Start with the knob loose, so that none of the screw

is showing, then slowly increase the tension until the thread
tension is balanced and the thread knots in the middle layers of
your fabric.

When the thread is

pulled the bobbin

will turn clockwise.

Turn the screw clockwise to

increase bobbin tension and

counter-clockwise to decrease

bobbin tension.

Timing The Machine

Parts Needed:

1. 2mm Allen Wrench

2. Timing Spacer

1. Loosen all three hook assembly set screws with a M2 allen wrench by inserting the wrench into
the machines timing hole when each set screw aligns with the hole.

2. Rotate the handwheel clockwise from the front of the machine so needle is raising out of the hook
assembly.

3. Bring the needle so it rests on the top of timing spacer, so the groove in the needle aligns in the
middle of the hook on the hook assembly. The needle should be as close as possible to the hook as­sembly without touching, roughly between 0.02mm and 0.075mm.

4. Tighten set screw, make sure needle doesn’t hit hook by watching to see if the needle bends
during rotation and there is no clicking noise. Rotate machine using the handwheel a full rotation to
ensure the needle doesn’t hit anywhere during rotation. If needle hits the hook assembly anywhere
during rotation adjust needle height up or down off center from hook in 0.25mm increments as ap­propriate to clear the collision.

5. Tighten the two remaining set screws.
Note: Only time the sewing machine if replacing hook assembly or machine comes out of timing.

Needle plate off center rubbing needle See needle plate instructions (page 21)

Hook assembly needs oil

Needle bar and mechanics need oil Only one or two drops of oil (page 29)

Bobbin winder is running

thread mast is directly over thread spool,

make sure thread spool is correctly

installed

Move machine quicker within speed

limitations so stitches don't overlap or

build up, sewing in one place will cause

thread to break

Check and replace the bobbin (page 12-

13)

Remove the bobbin and make sure that
it clicks when you press it into the hook

assembly (page 12-13)

Make sure bobbin tension is adjusted

correctly (page 12-13)

Clean between and around the tensioner

discs (page 26)

Re-adjust the hook holder (page 22)

Check the bobbin to ensure that it is

properly wound and that it is properly

inserted into the bobbin case (page 12-

Needle Information

Needle Diagram

Front View Side View

Shank

Shaft

Groove

Eye

Scarf

Shank - The part of the needle that is held in the
needle bar

Shaft - The long narrow part of the needle. The
diameter measurement is based on the shaft

Groove - Allows the thread to pass through the
fabric more easily

Eye - The hole near the tip of the needle for the
thread to pass through

Scarf - A cut away on the back of the needle
which allows the the hook on the bobbin
assembly to move past the needle and “hook” the
thread

Point - The sharp end of the needle. There are
different types of points for different applications
It’s important that you change you needle when
the point dulls or you may damage your fabric

For the best results:

• Use the recommended needle style and make
sure it is properly positioned

• Change your needle after 8 hours of use and

at the beginning of each project

• Choose your needle size based on the weight
and type of the thread that you use

• Use a multidirectional needle

Change your needle:

• If you can hear your needle popping into your
fabric

• If your thread is breaking

• If you are getting skipped or uneven stitches

• If you are getting puckered or damaged
fabrics

• If there is a popping or clunking sound made
by the sewing machine, this may be a sign
that the needle is bent

• After 8 hours of use and at the beginning of

each project

Thread Information

Things to consider when choosing a thread:

• The manufacturer of the thread matters (for thread weights and quality of thread)

• The weight and ply of the thread. For example: 40/3 means 40 weight 3 ply

• Not every manufacturer uses the same sizing scales. Sometimes it is easiest to examine and

compare threads to nd the size you want

• Thread may be measured in weight, tex, denier, number or composition standards
depending on the brand. Make sure that you know what scale the threads you are
considering are measured by

• The ply is how many strands are twisted together to make the thread

• The size of your thread is important because it will determine the appropriate needle size,

effect your tension and how visible the thread will be on you projects

• Needle sizes

• Too small of a needle will shred medium and heavy threads

• Too large of a needle will cause inconsistent stitching

• The processing and quality of thread. The following processes are the most commonly used:

• Mercerized - Cotton thread that has been treated in a way that increases the strength,

improves color quality and prevents fading.

• Glazed - Mercerized thread that has then been waxed or treated in another way to give it a
polished appearance. The coating may rub off and if this happens it may cause issues with your
machine

• Gassed - Cotton thread that has been exposed to a high temperature gas ame very rapidly.
This process removes fuzz and lint, giving the thread a smoother appearance.

• Bonded - The thread is treated with a resin to increase its strength. Usually used for heavy­duty applications such as upholstery

• Length of Fibers - Also know as the staple. This is the length of the cotton bers. Extra-long
staple cotton thread is better because it has better strength and creates less lint.

• Lubricants - Polyester threads generally will have a small amount of lubricant on them to
reduce friction. If the thread feels oily it has too much lubricant and should be avoided. Cotton
threads should not have lubricant on them

• Colorfastness - How well a thread will hold its color

For the best results:

• Use a thread from a thread cone unless you have the thread spool accessory

• It is recommended that you use a high quality thread when quilting with high quality fabric

• cotton thread works well with most cotton fabrics

• Don’t use old thread unless it will pass the yank test when pulling it off its cone.

• If you can break the thread by sharply yanking it off the cone or spool then it will break in
your machine and is not suitable

• Slow down with specialty threads

• Write down tension settings you like with each thread

• An example of a recommended thread is an Extra-Long Staple 100% Egyptian Cotton Mercerized
40/3

• Keep your thread out of direct sunlight, as this will cause the thread to fade and lose strength,
and do not store near extreme temperatures

Additional Tips

Thread

Thread weight is usually stamped on the edge of the spool or printed on the top or bottom of the
spool. Thread becomes heavier as weight designations

• 60 weight, a very thin/ne thread

• 50 weight

• 40 weight

Heavier weight threads are more noticeable on the quilt. A 50 weight thread is a popular choice for
quilting and 40 weight threads will be even more visible, while 60 weight versions will usually blend

into the fabric.

Thread weight is only one of many factors to consider when selecting machine quilting thread. Will
the thread’s color blend with the fabric or stand out to make quilting an important part of the design?
Consider whether you prefer the matte nish of a cotton thread, the shine of a rayon thread, or the

glimmer of a metallic thread. Go with what you like, get the right needle for it, and give the thread a

tryout. Remember to adjust the machines thread tension settings based on the type of thread you

are using.

.

Needles

The size of the needle shows on the front of the package with 2 sizes, the larger number of the two

is a metric designation and the smaller is the American standard equivalent. The larger the number,
the larger the diameter of the shaft of the needle. As a general rule, the ner the fabric you use on
the quilt, the ner the needle you should use as well.

Batting

The weight and thickness of batting is measured by its loft. A low loft batting is thinner and lighter

than a high loft batting. Low loft batting is used when a atter appearance is the desired look for
a quilt. High loft batting should be used if a uffy full quilt is the goal. Typically, wool batting is the

thickest of the various types of batting and bamboo is the lightest. Wool is known for providing the
most warmth, followed by polyester and then cotton. Choose the batting that will provide you with

the right look and feel for your project.
