Maintenance schedule

WhenWhat to doWhy
Daily (or before each shift)Clean the rotary hook area and bobbin case.Removes lint and thread debris that can cause skipped stitches, thread breaks, and damage to the hook.
Daily (or before each shift)Oil all designated points, especially the rotary hook, needle bars, and main shaft bearings.Reduces friction, prevents wear, and ensures smooth operation of moving parts. Refer to your manual for specific oiling points.
Daily (or before each shift)Wipe down the machine exterior and clear any visible lint/dust.Prevents dust from entering internal mechanisms and keeps the machine in good condition.
Weekly (or every 40-60 operating hours)Clean under the needle plate and around the thread take-up levers.Removes hidden lint and debris that can affect stitch quality and thread path.
Weekly (or every 40-60 operating hours)Inspect all thread guides and tension discs for burrs or damage.Damaged guides can fray thread and cause breaks. Clean tension discs ensure consistent tension.
Weekly (or every 40-60 operating hours)Check needle bar play and ensure needle clamps are secure.Excessive play can lead to needle breakage and poor stitch quality. Loose clamps can cause needles to fall out.
Monthly (or every 160-200 operating hours)Inspect all timing belts (main drive, head drive) for wear, cracks, or fraying. Check tension.Worn or loose belts can cause misaligned designs, skipped stitches, and machine damage. Adjust tension as per manual.
Monthly (or every 160-200 operating hours)Check all springs (jump, take-up, needle retention) for proper tension and signs of fatigue/breakage.Weak or broken springs lead to various stitching issues and can affect machine timing.
Monthly (or every 160-200 operating hours)Clean and inspect the thread trimming mechanism (reciprocator, knives).Ensures clean thread cuts and prevents thread jams. Remove any accumulated thread bits.
Every 500-1000 operating hours (or annually)Inspect and lubricate main shafts, bearings, and gears.Prevents excessive wear on critical moving parts. This may require partial disassembly.
Every 500-1000 operating hours (or annually)Check and adjust machine timing (needle bar, hook, trimmer) if necessary.Ensures optimal stitch formation and machine synchronization. Refer to service manual or consult a technician.

Stop and call a technician if

  • If you encounter persistent error codes that you cannot resolve with basic troubleshooting.
  • If the machine exhibits severe mechanical noise, grinding, or seizing.
  • If you suspect a problem with a circuit board or complex electronic component.
  • If you are unsure about performing a repair that involves critical timing adjustments (e.g., hook timing, needle bar timing).
  • If you've performed all recommended maintenance and troubleshooting steps, but the issue persists.

Prevent it coming back

  • Always use high-quality threads and needles appropriate for your fabric to reduce stress on machine components.
  • Ensure proper thread tension settings to prevent excessive strain on the thread path and needle bar mechanisms.
  • Keep your work area clean to prevent dust and lint from accumulating inside the machine.
  • Use only the recommended type and grade of machine oil and lubricate regularly.
  • Avoid forcing parts or making aggressive adjustments; if something feels stuck, investigate the cause gently.
  • Regularly check and adjust belt tensions to prevent slippage and premature wear.
  • Train operators on proper machine usage and basic troubleshooting to minimize user-induced damage.

Frequently asked questions

How often should I oil my Tajima TMFD machine?

You should oil your Tajima TMFD machine daily, or at the start of each shift, using the recommended machine oil. Pay attention to all designated oiling points, especially around the rotary hook, needle bars, and other moving parts. Refer to your machine's manual for specific oiling locations and frequency.

What are the most common wear parts on a Tajima TMFD?

The most common wear parts on a Tajima TMFD series machine are springs (like jump control rod springs, hook thread take-up springs, and needle retention springs), bushings (presser foot, bobbin shaft), and timing belts. These parts are subject to constant movement, tension, and friction, leading to eventual wear.

Why is my Tajima TMFD making a new noise?

New noises often indicate a problem. It could be due to lack of lubrication, a loose or worn part (like a belt, bearing, or gear), thread caught in a mechanism, or an issue with the rotary hook. Stop the machine immediately, inspect for obvious issues, lubricate, and if the noise persists, investigate further or consult a technician.

Can I use generic parts for my Tajima TMFD?

While some generic parts may fit, using genuine or high-quality aftermarket parts specifically designed for Tajima TMFD machines is highly recommended. Inferior parts can lead to premature failure, poor stitch quality, and potential damage to other machine components. Always prioritize quality for critical moving parts.

How do I know when to replace a timing belt?

Inspect your timing belts monthly for signs of wear such as cracks, fraying, missing teeth, or excessive stretching. If you notice any of these symptoms, or if your machine experiences skipped stitches or misaligned designs that aren't resolved by other means, it's time to replace the timing belt. Always check belt tension regularly.
