Read the model-specific requirements with each answer before choosing parts.
This manual says BERNINA requires needle system130/705H.
Match thread size to needle size so thread moves smoothly in the long front groove; excessively thick thread/fine needle can jam and break thread.
With power on and empty bobbin on spindle, route spool thread through rear guide/pre-tension stud, wrap2–3turns and engage lever; motor stops when full.
With needle raised and power off, remove case using latch; hold latch to insert with case opening at top until engaged, then close cover.
Insert bobbin for clockwise rotation; pull thread left under spring into T-shaped slit.
The artista 640 manual states BERNINA rotary hook system.
Raise needle/foot and switch off; lift clamping lever to remove foot, guide replacement upwards over cone and clamp lever down.
Standard pressure for normal work, reduced for jerseys/loose knits to prevent stretch, increased for firm fabrics to improve feed.
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
On a flat even surface, place module behind free arm, slide from left to engage lugs; plug flat side forward into right-side socket. Always separate module/machine for transport.
Use screen-recommended smallest appropriate hoop; raise needle/foot, fabric right side up/attachment left, squeeze mechanism, align bracket and push down until engaged.
Power off and unplug; brush lint under plate/hook and hook race with brush/cotton swab, never sharp instruments; damp cloth for screen/body. Do not use alcohol or solvents.
Power off and unplug, put one drop of oil in hook race; afterwards run briefly without thread to prevent oil soiling work.
Button flush means feed raised for machine feeding; depressed means lowered for darning/freehand work and module embroidery.
Let fabric feed evenly; pulling, pushing or holding it back gives uneven stitches. Very short stitches advance slowly even at full sewing speed.
Switch off, raise needle/foot, lower feed, press back-right plate corner to flip/remove; replace over openingA and press until click.
Turn power switch to0off for threading/changing needle, threading bobbin or changing foot. Unplug before cleaning, lubricating, cover removal or servicing.
Raise needle and foot, power off, use foam pad and clockwise spool with suitable disc/no clearance; guideA/tension slit/downrightB/upleftC into take-up/downD/E.
Needle raised and foot lowered: press leverA, guide around hookB right of needle/from front into guide, release lever and pull loop through eye.
9.0 mm stitch width as listed in the Version 4 service table; row does not explicitly say maximum
Check130/705H needle, condition, full insertion and point suitable for fabric; damaged stitch plate/hook requires dealer.
Use the full source procedure and its safety precautions. A short referenced answer is not a substitute for service documentation or qualified electrical/mechanical repair.
Service-manual availability and service-only procedures remain unestablished unless separately cataloged and reviewed.
Answers use this model’s manual. Other editions, accessory groups and replacement parts need their own supporting references.
