HQ Infi nity User Manual
| 2 9
The Infi nity uses the MR needle system. Note that the needle has a
round shank rather than a shank with a fl at side like home sewing
m ac h i n e s u s e .
If you use the recommended needle, you will experience:
• Fewer skipped sti tches
• Less needle breakage
• Less thread breakage, especially at high speeds
• Less thread splicing or shredding
• Opti mum fabric protecti on
Â
IMPORTANT: Change the needle regularly. We recommend you use a new needle for each new quilt
loaded on the machine, and any ti me the needle becomes bent, dull, or burred.
U
CAUTION: A damaged needle may result in poor sti tching quality or may even damage the machine
or your quilt.

1 . Move the needle bar to the up positi on by pressing the needle up/down control on the handles.
2 . Turn off all power to the machine.
3. Loosen the needle bar clamp screw with the
2.5mm hex wrench.
4 . Remove the old needle by pulling it down. Discard the old needle in a safe way.
5 . With the scarf of the needle (indentati on at
the back of the needle) facing the rear of the
machine and the long groove down the front
o f t h e n e e d l e f ac i n g t h e f r o n t o f t h e m a c h i n e ,
push the needle all the way up into the needle
bar unti l it stops. Check the sight opening to
verify that the top of the needle can go no
farther up.
U
CAUTION: Check the needle to confi rm it is fully inserted. The needle bar has a sight opening
above the needle bar clamp screw. Make sure the needle is touching the top of the sight opening.
If it isn’t, the machine ti ming will be off and it may be possible for the needle to collide with
internal parts causing damage not covered by warranty.
6. Carefully ti ghten the needle bar clamp screw.
U
CAUTION: Although you can use your fi ngers to ti ghten the needle bar clamp screw, we recommend
that aft er fi nger-ti ghtening the screw you use the 2.5mm hex wrench to ti ghten it just a bit more.
The Infi nity runs at very high speeds and this ensures the needle will not loosen while quilti ng.
However, do not over ti ghten the needle clamp screw as this may strip the threads of the screw.
Stripped threads are not covered under the warranty. It may also become diffi cult to insert the
needle properly into the needle bar. Once the screw no longer turns freely by hand, gently turn the
screwdriver unti l the screw is ti ghtened snuggly.

Machine Quilting Tip: Needle Requirements
For general quilti ng, a size 16/100 needle will accommodate most threads and fabrics.
Heavier threads, such as top sti tch and some decorati ve threads, require a larger needle
such as 18/110 or 20/120. Loft y batt s and heavier fabrics such as denim, canvas, or densely
woven fabric may also require a larger needle.
Hopping Feet
Your machine comes with two hopping feet: a ruler foot (comes installed) and an open-toe foot. Use the
ruler foot for everyday quilti ng and ruler work, and use the open-toe foot when you need greater sti tch
visibility (such as when you are micro quilti ng).

Hopping Foot at: htt p://www.handiquilter.com/videos/hq-infi nity/223/.
