Important Safeguards
When using an electrical appliance, basic safety precautions should always be followed,
including the following.
DANGER - To reduce the risk of electric shock, do not leave the machine unattended when plugged
in. Always unplug this machine from the electric outlet immediately after using and before cleaning.
WARNING - To reduce the risk of burns, re, electric shock, or injury to persons:
• This appliance is not to be used by persons (including children) with reduced physical, sensory, or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance in a safe way and understand the hazards involved.
• Children should be supervised to ensure that they do not play with the appliance. Children shall not
play with the appliance.
• Cleaning and user maintenance shall not be made by children without supervision.
• Use this machine only for its intended use as described in this manual. Use only attachments
recommended by the manufacturer as contained within this manual.
• Never operate this machine if it has a damaged cord or plug, it is not working properly, or it has been
dropped, damaged, or dropped into water. Return the machine to the nearest authorized dealer or
service center for examination, repair, or electrical or mechanical adjustment.
• Never operate the machine with any air openings blocked. Keep ventilation openings of the quilting
machine free from the accumulation of lint, dust, and loose cloth.
• Never drop or insert any object into any opening.
• The appliance is intended for indoor use only. Do not use outdoors.
• Do not operate where aerosol (spray) products are being used or where oxygen is being
administered.
• Connect this appliance to a properly grounded outlet only. See grounding instructions on next page.
• To disconnect, turn all controls to the o position, then remove the plug from the outlet by grasping
the plug. Do not pull on cord. Always switch o or unplug the appliance when leaving it unattended.
• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
• If the supply cord is damaged, it must by replaced by the manufacturer, its service agent or similarly
qualied persons in order to avoid a hazard.
• Keep ngers away from all moving parts. Special care is required around the quilting machine needle.
• Always use the proper needle plate. The wrong plate can cause the needle to break.
• Do not use bent or damaged needles.
• Do not pull or push fabric while stitching. It may deect the needle, causing it to break.
• Switch the quilting machine o when making any adjustments in the needle area, such as threading
the needle, changing the needle, or changing the presser foot, etc.
• Always unplug the quilting machine from the electrical outlet when removing covers, lubricating, or
when making any other user servicing adjustments mentioned in the instruction manual.
• CAUTION: In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this
appliance must not be supplied through an external switching device, such as a timer, or connected
to a circuit that is regularly switched on and o by the utility.
If using this machine in an area with inconsistent input power, it is recommended the surge protector
is connected to a backup battery supply.
SAVE THESE INSTRUCTIONS!
Do not discard box or packaging.

Important Safeguards (continued)
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of malfunction or breakdown, grounding provides a path
of least resistance for electric current to reduce the risk of electric shock. This product is equipped
with a cord that has an equipment-grounding conductor and a grounding plug. Plug the cord from the
quilting machine into a surge protector. The surge protector 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 pin as illustrated above (A). A
temporary adapter, shown in (B) and (C), may be used to connect this plug to a 2-pole receptacle (B) if
a properly grounded outlet is not available. The temporary adapter 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 adapter must be connected to a permanent ground such as a properly grounded
outlet box cover. Whenever the adapter 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.

1. Power o the machine.
2. Set the large thread tensioner to “1” to expose the tensioner discs. Use the lint brush or a can
of compressed air to clear away lint and thread remnants.
Note: Lint build-up between the tensioner discs can prevent proper thread tensioning.

9. Place 1-2 drops of oil into the hook assembly
between the inner part (shown in gray) and
outer part (shown in blue).
3. Set the bobbin aside. Clean the bobbin case
with the lint brush or compressed air. Be
sure to clean the area under the bobbin
tension thread arm.
7. In and around the hook assembly, clear
away any lint, cloth, and thread remnants.
8. Rotate the hand wheel until the needle is
halfway down. This will put the hook in the
best position for oiling.
2. Pull the release lever (shown in blue) on
the bobbin case to remove it from the hook
assembly. If the case won’t release, raise the
needle with the hand wheel at the rear of
the machine.

Choosing Your Needle
Needle Sizes
Needle Size Thread Size and Type
14 / 90 • mono-lament
• 100 wt. silk
• 60 wt. polyester
16 / 100 • mono-lament
• 60 wt. polyester or cotton
• 50 wt. cotton
18 / 110 • 50 wt. polyester
• 40 wt. cottons and polyester
• 30 wt. cotton and polyester
20 / 125 • 30 wt. or heavier of any thread
The following are the recommended needle styles for your machine:
• DPX5 MR
• 134 MR
• 1955 MR
Choose the size of your needle based upon the thread you’re using. Thicker thread requires a thicker
needle. Remember, the thicker the thread, the lower the thread weight (wt.) number.
Using the wrong type of needle, or using a needle that is bent, broken, or blunt, can damage the
fabric, the machine, and needle. For best results:
• Use the recommended needle style for your machine (see below).
• Use the needle size appropriate for the weight and type of thread you’re using (see below).
• Never use a needle that is dull, bent, burred, or damaged.
• Use multi-directional needles.
• Change your needle after 8 hours of use and at the beginning of each project.

• Shank: Where the needle bar grasps the needle.
• Shaft: The long, narrow part of the needle. Needle size is based upon the diameter of the
needle shaft.
• Groove: Reaching from the top to the bottom of the needle shaft, the groove allows thread to
pass through the fabric more easily and without getting damaged.
• Eye: Hole near needle point where the needle is threaded.
• Scarf: A cut-away on the back of the needle that allows the needle to t smoothly within the
hook assembly when quilting.
• Point: The sharp end of the needle. Choose the type of needle point to t your project, and
always replace your needle once the point is dull.
