Position machine: Place on stable surface at comfortable height.
Power connection: Plug into appropriate electrical outlet (if electric model).
Thread machine: Follow threading diagram for upper and lower threading.
Insert bobbin: Place bobbin in case with thread pulling counterclockwise.
Test stitches: Use scrap fabric to test tension and stitch quality.
Adjust settings: Modify tension and stitch length for fabric type.

CAUTION! Keep fingers away from moving needle during operation.

Threading Instructions

Upper Threading: Follow numbered guides from spool pin to needle.
Needle Position: Flat side of needle faces back; insert fully into clamp.
Tension Settings: 4-5 for medium weight fabrics; adjust as needed.
Bobbin Threading: Wind bobbin evenly; insert with thread through tension spring.
Thread Types: Use quality cotton or polyester thread (size 40-50).
Needle Types: Universal point for woven fabrics; ball point for knits.
Thread Quality: Avoid old or brittle thread that may break during sewing.

Stitch Length: 2.0-2.5mm for medium fabrics, 1.5-2.0mm for delicate fabrics, 3.0-4.0mm for basting. Tension: Balanced (threads meet in middle), Light (for delicate fabrics), Heavy (for thick materials). Reverse: Engage reverse lever to secure seam beginnings and endings.

Maintenance & Oil Guide

Regular oiling prevents wear and ensures smooth operation.

Clean lint: Remove bobbin case and brush out accumulated lint.
Oil points: Apply sewing machine oil to moving parts as indicated in diagram.
Frequency: Oil every 8-10 hours of use or every 3 months.
Wipe excess: Run machine on scrap fabric to absorb excess oil.
