Juki LU-562 / 563 Series Maintenance Guide

1. Needle high likelihood

How to tell

Skipped stitches, thread breakage, damaged fabric, needle bending or breaking, dull point, or burrs on the needle shaft.

Fix

1. Inspect the needle for straightness, sharpness, and any burrs. Run a finger gently along the point to feel for roughness.
2. Ensure the needle is inserted correctly and fully seated in the needle bar.
3. Replace the needle with a new, correct type and size for your material and thread. Always use high-quality needles.

2. Rotary Hook high likelihood

How to tell

Frequent thread shredding or breakage, inconsistent stitch formation, skipped stitches, excessive noise from the hook area, or visible burrs, nicks, or wear on the hook point or race.

Fix

1. Remove the bobbin case and thoroughly clean the hook area of lint and debris.
2. Carefully inspect the hook point and the bobbin case race for any signs of wear, nicks, or burrs. Use a magnifying glass if necessary.
3. If damage is found, replace the rotary hook. For LU-563 models, consider the JUKI B1830-563-BA0 Large Rotary Hook for LU-563, LU-563-3, LU-1508, LU-1508H, LU-1509NH. For other compatible models, the SINGER Industrial Rotary Hook HSH-11-55 240558 10655 YZH-111 for 111W155 211G155 211U165 may also be suitable.
4. After replacement, ensure proper hook timing and needle-to-hook clearance according to your machine's service manual.

The Juki LU-562 / 563 series uses a large capacity rotary hook. Inspect for burrs and nicks regularly.

3. Feed Dog and Needle Plate medium likelihood

How to tell

Poor or uneven material feeding, marks on the fabric, inconsistent stitch length, or visible wear, nicks, or grooves on the feed dog teeth or the needle plate hole.

Fix

1. Remove the needle plate and clean thoroughly underneath, removing all lint and debris.
2. Inspect the teeth of the feed dog for wear, damage, or accumulation of hardened lint.
3. Inspect the needle plate hole for enlargement, burrs, or nicks caused by needle strikes.
4. If significant wear or damage is present, replace the feed dog and/or needle plate. Ensure you use parts specific to the LU-562 / 563 series for proper fit and function.

4. Bed Slide Set (Left & Right Cover Plates) medium likelihood

How to tell

Difficulty in smoothly moving material under the presser foot, excessive friction, scratching of material, or visible wear, grooves, or damage on the surface of the bed slides.

Fix

1. Remove the bed slide set and clean any accumulated lint, dust, or hardened oil from the underside and the machine bed channel.
2. Inspect the sliding surfaces of the Juki LU-562 LU-563 LU-562N LU-563N Bed Slide Set – Left & Right Cover Plates for wear, deep scratches, or burrs.
3. If worn or damaged, replace the entire set to ensure smooth material handling.
4. Apply a thin layer of machine oil to the sliding surfaces before reinstallation, as specified in your machine manual.

The Juki LU-562 LU-563 LU-562N LU-563N Bed Slide Set – Left & Right Cover Plates are designed to provide a smooth surface for material movement. Wear can lead to feeding issues.

5. Bed Slide Spring & Screw low likelihood

How to tell

Loose or rattling bed slides, bed slides not staying securely in place, or visible damage, bending, or breakage of the spring.

Fix

1. Inspect the Juki Bed Slide Spring & Screw for LU-562, LU-563, LU-1560, LU-1508, LU-1509, LU-1510, LH-1152 for proper tension and integrity.
2. If the spring is bent, broken, or the screw is stripped, replace the affected components.
3. Ensure the screw is tightened sufficiently to hold the bed slide securely but not so tight as to impede its movement or damage the spring.

These small parts are crucial for holding the bed slides in place. Check them if your bed slides feel loose.

6. Thread Tension Discs and Springs medium likelihood

How to tell

Inconsistent thread tension, looping stitches, thread shredding at the tension assembly, or visible grooves, nicks, or corrosion on the tension discs, or a weak/broken tension spring.

Fix

1. Remove the tension assembly and thoroughly clean all components, especially between the tension discs, to remove lint and wax buildup.
2. Inspect the surfaces of the tension discs for any grooves, nicks, or rough spots that could snag the thread.
3. Check the tension spring for proper tension and ensure it's not bent or broken.
4. If discs are damaged or the spring is weak, replace the affected components. Ensure proper reassembly and tension adjustment.

7. Drive Belts low likelihood

How to tell

Squealing noises during operation, loss of power, inconsistent machine speed, or visible cracks, fraying, or looseness in the motor drive belt or other internal belts.

Fix

1. Visually inspect all accessible drive belts for signs of wear, cracking, fraying, or excessive looseness.
2. Check belt tension. A belt that is too loose can slip, while one that is too tight can put undue stress on bearings.
3. If a belt shows significant wear or is damaged, replace it with a new belt of the correct size and type. Refer to your machine's manual for specific belt specifications and replacement procedures.
