First observation

Stop now. Is anything damaged or missing?

Switch off and unplug before touching the needle, bobbin, foot, or plate area. Do not run another strike to identify it.

Preparing the interactive choices…

IllustrationCompatibility comes from the manual. Contact means stop.
Approved parts and mode

A symbolic clear path; not a measured safe gap.

Needle contact

Contact with foot or plate is a stop signal.

Confirm the permitted needle, foot, plate and stitch mode before another test.

No hook/timing geometry or internal adjustment. Do not rotate forcibly or run a contacting needle.

Use your exact model manual for instructions.

Compare the observation

What matches—and what changes the path?

NORMAL REFERENCE

Expected state

A documented needle/foot/plate combination clears without contact.

OBSERVATION 1

Needle hits metal

OBSERVATION 2

Needle bends or breaks

OBSERVATION 3

A fragment cannot be accounted for

Visual reference

Compare the cues. Keep the limits in view.

Open a comparison when you need it. Illustrations explain what to observe; your own sample and exact model manual guide the check.

Locate needle and upper-thread checkpoints; follow the exact threading order.
IllustrationFind the checkpoints. Use your manual's route.
Upper-thread checkpoints

Spool → guides/take-up → needle guide/eye; abstract checklist, not routing geometry.

Needle installation

Check approved system, orientation, full seating and clamp per manual.

Disconnect power before touching the needle or thread path.

No universal flat-side direction or insertion measurement. Do not run a known misinstalled needle.
