Troubleshooting Guide

SymptomPossible CauseCorrective Action
Thread breakingIncorrect tension/damaged needleAdjust tension settings; replace needle; check thread path
Skip stitchesWrong needle type/bent needleUse correct needle system; replace bent needle; check timing
Uneven feedingWorn feed dogs/pressure issueReplace feed dogs; adjust presser foot pressure; clean feed area
Motor overloadExcessive speed/mechanical bindingReduce speed; check for obstructions; lubricate mechanisms
Bobbin thread issuesIncorrect winding/hook problemsRewind bobbin properly; clean hook area; check bobbin case

Reset: Power cycle machine; consult error code manual.

Service: Contact certified technician for complex issues.
