Timing Belt Adjustment
Note: Re-timing your machine is a last resort. Your quilting machine will not just “go out of adjustment” on
its own. Jamming the machine with a broken needle, hitting a guide ruler with the needle bar or getting a
cleaning rag stuck in the hook assembly are usually the only ways the timing can be affected. Breaking
thread or looping problems are generally NOT related to faulty timing.
Before you look at re-timing, you will need to verify the hook rotation to see if the hook is rotating properly
and to see if the needle touches the hook assembly as it is moving down. This would indicate that either
your timing belt requires an adjustment or that you machine may need to be re-timed. Always check the
Timing Belt before re-timing the machine.

If needle touches Hook Assembly sooner than it should (before thumb), your machine needs a belt
adjustment.
