Which maintenance guideline is correctly stated after cleaning?

• A. Change needle after every 10 hours, clean with nylon brush, never use compressed air to blow out lint, and lubricate parts according to the directions in your manual
• B. Change needle after every 50 hours, spray air to remove lint, and never oil parts
• C. Keep needle in place, never brush lint, and oil weekly
• D. Use compressed air to remove lint and oil sparingly

Answer: (A)

Focusing on post-cleaning maintenance, the safest and most effective approach is to replace the needle, clean away lint with a gentle brush, avoid using compressed air to blast lint, and lubricate only as the manual says. Replacing the needle after cleaning is essential because a fresh, sharp needle reduces the risk of skipped stitches and fabric snagging. A nylon brush provides a careful way to lift and remove lint without pushing it deeper into the machine’s interior. Compressed air can push lint into bearings or other tight spaces and can scatter dust where it can cause wear or jams, so it’s not recommended. Lubrication must follow the machine’s manual to ensure the right parts are oiled with the correct type and amount of oil; over-lubricating or wrong lubrication can attract lint or damage moving parts. By sticking to these steps, you maintain smooth operation and extend the life of the sewing machine.
