Tajima TLMX Series: Essential Maintenance Schedule & Wear Parts Guide

1. Rotary Hook Bobbin high likelihood

How to tell

Skipped stitches, poor tension, frequent thread breaks, unusual noise from the hook area, or visible burrs, nicks, or excessive wear on the hook body. The bobbin case may also show signs of wear.

Fix

1. Inspect the rotary hook for burrs, nicks, or excessive wear on the point and race. Clean thoroughly to remove lint and debris.
2. Check the bobbin case for damage or wear. Ensure the bobbin tension spring is functioning correctly.
3. If damaged or excessively worn, replace the Onloyo 050260010020 Rotary Hook Bobbin:Regular. Ensure proper timing is checked and adjusted if necessary after replacement.

Always keep spare rotary hooks and bobbin cases on hand, as they are high-wear items.

2. Thread Hook Wiper high likelihood

How to tell

Loose thread tails after trimming, thread loops left on the fabric, or visible wear, tears, or hardening of the wiper material. The wiper may also appear bent or misaligned.

Fix

1. Visually inspect the Onloyo Genuine Thread Hook Wiper for any signs of wear, damage, or hardening.
2. Ensure the wiper is correctly positioned and making proper contact with the needle plate during trimming.
3. If worn or damaged, replace the Onloyo Genuine Thread Hook Wiper. Verify its function by performing test trims.

A worn wiper can lead to frequent thread trimming issues and requires prompt replacement.

3. Needle Bar Reciprocator medium likelihood

How to tell

Excessive play or wobble in the needle bar, inconsistent needle depth, unusual clicking or grinding noises during needle movement, or poor stitch formation. Visible wear on the cam surfaces or bearings of the reciprocator.

Fix

1. Carefully check each needle bar for lateral and vertical play. Excessive movement indicates wear.
2. Inspect the Tajima 080210360A79 UN25009400GN Needle Bar Reciprocator Set or Tajima 080210360A22 UN25009400GN Needle Bar Reciprocator GN[A] for wear on its moving surfaces.
3. If worn, replace the reciprocator set. This is a precision component and may require careful adjustment of needle bar height and depth after installation. Consult your machine manual for specific procedures.

Proper adjustment after replacement is critical for stitch quality and machine longevity.

4. Needle Retention Compression Spring medium likelihood

How to tell

Needles falling out of the needle bar, loose needles, or difficulty in securely inserting needles. The spring may appear compressed, bent, or broken.

Fix

1. Remove the needle and inspect the Onloyo 507605030044 EF0618030000 Needle Retention Compression Spring inside the needle bar.
2. Check if the spring has lost its tension, is deformed, or broken.
3. If faulty, replace the spring with a new Onloyo 507605030044 EF0618030000 Needle Retention Compression Spring. Ensure the needle is held firmly after replacement.

5. Thread Guide Collar Ceramic Coil medium likelihood

How to tell

Frequent thread breaks, fraying thread, or visible nicks, grooves, or rough spots on the ceramic surface of the Tajima 516503010011 MX0521010000 Thread Guide Collar Ceramic Coil. Thread may not move smoothly through the guide.

Fix

1. Carefully inspect all ceramic thread guides for any signs of wear, chipping, or roughness by running a piece of thread through them.
2. If any damage is found, replace the affected Tajima 516503010011 MX0521010000 Thread Guide Collar Ceramic Coil. Ensure the new guide is securely seated.

Smooth thread path is essential for preventing thread breaks and maintaining tension.

6. Thread Break Sensor (TC Sensor Substrate) low likelihood

How to tell

Machine failing to detect thread breaks, leading to incomplete embroidery, or false thread break errors when no break has occurred. The sensor may appear dirty or damaged.

Fix

1. Clean the Onloyo 0J2602300A23 TC Sensor Substrate Thread Break Sensor thoroughly with compressed air or a soft brush to remove lint and debris.
2. Check the sensor's wiring for any damage or loose connections.
3. If cleaning does not resolve the issue and the sensor is suspected to be faulty, replace the Onloyo 0J2602300A23 TC Sensor Substrate Thread Break Sensor. Calibration may be required after replacement; consult your manual.

A malfunctioning sensor can cause significant production issues.

7. Electromagnetic Induction Substrate A (Magnetic Sensor A) low likelihood

How to tell

Inconsistent or incorrect needle position detection, issues with color changes, or machine stopping unexpectedly with sensor-related errors. The sensor may appear dirty or physically damaged.

Fix

1. Inspect the Onloyo 0J4204400000 0J4200800012 Electromagnetic Induction Substrate A for cleanliness and physical damage.
2. Ensure all connections to the sensor are secure.
3. If troubleshooting points to a faulty sensor, replace the Onloyo 0J4204400000 0J4200800012 Electromagnetic Induction Substrate A. Recalibration of machine head positions may be necessary after replacement.
