4-5
Bobbin Thread Low
If the bobbin thread runs low, the alarm will sound and the display will read BOBBIN THREAD.
Dust Accumulation
If excessive dust accumulates inside the bobbin case, the alarm will sound and the display will
read DUST! KEEP CLEAN.
Upper Shaft Lock
If the upper shaft stops moving and locks up due to excessive thread build-up in the bobbin case,
the alarm will sound and the display will read REMOVE THE LOCK! Clear the lock.
Hoop Limits
If your selected design is too large for the current hoop, there is a chance the hoop will move
beneath the needle during embroidering, which will damage the needle, hoop, and possibly the
drive mechanism. Using the Trace option prior to embroidering eliminates the chance of this
occurring. However, if the hoop limits are exceeded, the alarm will sound and the display will read
RACK LIMIT.
