Hook timing
1. On the left side of your machine, you will find two small openings. On one, you will
see the degree the machine is aligned to. On the other one, you’ll find a hex screw.
See Figure 116.
2. Use the 5 mm Allen wrench to rotate the axis counterclockwise until the dial aligns
to 100 degrees.
3. Turn the machine back on. When the panel shows the main menu screen, press
the 100 degree button on your panel. At this point, the machine should be ready to
embroider.
Hook timing refers to the synchronization of the rotary hook
with the needle. Proper timing is critical for embroidery
quality and to prevent issues. If the space between the
needle and the hook point is out of range, the thread will
not catch, causing thread breaks. If the space between
the needle and hook point is too close, it will cause broken
needles. See Figure 117.
You can set your rotary hook timing by rotating the main
shaft of your machine to a specific degree and then
adjusting the rotary hook at that particular degree. This is known as the “timing degree.” The CHT2’s
timing degree is 201 degrees.
When timing is correct, the tip of the rotary hook should be directly lined up behind the needle’s scarf,
and the proper space between the needle and the hook should be 0.1 mm to 0.3 mm. See Figure 118.

aligning your machine to 100 degrees.
Then, make sure there is a working needle number displayed on the needle icon. If no needle is displayed,
refer to the “No needle error” section.
Once you’ve made sure a working needle is selected, press the 100 degree button on your control
panel once again. Most of the time, your machine’s main axis will align itself after this step, and you
may continue operating your machine.
If you are still receiving an error message after performing this step, you will need to align it manually
using the degree wheel on the left side of your machine. Note: You must turn off the machine before
performing this step.
