HQ In nity User Manual | 2 9
The In nity uses the MR needle system. Note that the needle has a
round shank rather than a shank with a 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 s tches
• Less needle breakage
• Less thread breakage, especially at high speeds
• Less thread splicing or shredding
• Op mum fabric protec on
 IMPORTANT: Change the needle regularly. We recommend you use a new needle for each new quilt
loaded on the machine, and any me the needle becomes bent, dull, or burred.
U CAUTION: A damaged needle may result in poor s tching quality or may even damage the machine
or your quilt.

2.5mm hex wrench.

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 un 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 con 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 ming will be o and it may be possible for the needle to collide with
internal parts causing damage not covered by warranty.
6. Carefully ghten the needle bar clamp screw.
U CAUTION: Although you can use your ngers to ghten the needle bar clamp screw, we recommend
that a er nger- ghtening the screw you use the 2.5mm hex wrench to ghten it just a bit more.
The In nity runs at very high speeds and this ensures the needle will not loosen while quil ng.
However, do not over 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 di cult to insert the
needle properly into the needle bar. Once the screw no longer turns freely by hand, gently turn the
screwdriver un l the screw is ghtened snuggly.

Machine Quilting Tip: Needle Requirements
For general quil ng, a size 16/100 needle will accommodate most threads and fabrics.
Heavier threads, such as top s tch and some decora ve threads, require a larger needle
such as 18/110 or 20/120. Lo y ba 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 quil ng and ruler work, and use the open-toe foot when you need greater s tch
visibility (such as when you are micro quil ng).

Hopping Foot at: h p://www.handiquilter.com/videos/hq-in nity/223/.
