Threader to fit Brother Innovis Sewing and Embroidery models: NV1500(D), NV1& NV1e, V3, V5 and V7.
Also the Innovis VQ2 Sewing Machine.
These are very tricky to fit! Remove needle and pull the threader mechanism carefully off the shaft so the parts remain intact. Carefully replace just this part and re-assemble pushing onto shaft and locating the positioning pin in groove.
Note: The NV1 has a spring that needs carefully disconnecting before the unit slides off the shaft. The V-series models additionally have a circlip that needs removing from the end of the shaft.
Watch a video on replacing a similar type of threader onto a QC1000 machine. Please be aware that each machine varies slightly and this video is a guide. Check your own machine thoroughly before dismantling the threader.
