Using and maintaining this machine

Check the conditions alongside each answer. Foot attachment, shank type and adapter requirements are separate; one does not establish universal accessory fit.

Features and specifications

Maximum sewing speed

conditional

The T-8450C-005 specification card lists a maximum sewing speed of 3,000 stitches per minute.

  • This is the exact -005 card rating, not a claim for the T-8450C base, -003, or neighboring models.

Source evidence · 1 unique proof passage: Profile Proof E1

Maximum stitch length

conditional

Maximum stitch length is 5 mm for T-8450C-005.

  • Exact -005 card only; the adjacent T-8720C/8750C card gives a different value.

Source evidence · 1 unique proof passage: Profile Proof E1

Feed dog height

conditional

The T-8450C-005 specification lists a 1 mm feed-dog height.

  • Specification measurement only; not a foot or needle-plate clearance guarantee.

Source evidence · 1 unique proof passage: Profile Proof E1

Presser feet and adapters

Lifting lever height

conditional

The presser-foot height by lifting lever is 7 mm.

  • Exact -005 card measurement; it does not establish shank or compatible-foot geometry.

Source evidence · 1 unique proof passage: Profile Proof E1

Knee lifter height

conditional

The presser-foot height by knee lifter is 13 mm.

  • Exact -005 card measurement; not an accessory-fit or adapter claim.

Needles and threading

Listed system

conditional

The needle row lists DP×5 for T-8450C-005.

  • The multiplication glyph was visually confirmed on the original page; the native text has a damaged glyph. No alternative-system equivalence or exclusive-fit claim is inferred.

Source evidence · 1 unique proof passage: Profile Proof E2

Listed size range

conditional

The same -005 needle row lists sizes #14–#22.

  • The range belongs to T-8450C-005; do not borrow a neighboring subclass size range.
