Barudan BEVT Series Embroidery Machine Maintenance Guide

1. Needles high likelihood

How to tell

Frequent thread breaks, skipped stitches, needle breaks, or dull/bent needle tips visible upon inspection. Poor stitch quality or fabric damage.

Fix

1. Inspect needles daily for bends, burrs, or dullness. Replace immediately if any damage is found.
2. Always use the correct needle type and size for your fabric and thread.
3. Replace all needles after a set number of production hours (e.g., 8-16 hours of continuous use) or when starting a new large project, even if they appear fine, to prevent unexpected issues.

2. Rotary Hook Assembly high likelihood

How to tell

Noisy operation, frequent thread breaks, loose stitches, bobbin thread showing on top, or bird's nesting. Inspect the hook point for burrs, nicks, or excessive wear.

Fix

1. Remove the bobbin case and clean the rotary hook area daily, removing lint and thread debris.
2. Inspect the hook point and race for damage or wear. Smooth any minor burrs with fine-grit sandpaper or a hook file, but replace if damage is significant.
3. Lubricate the rotary hook race with a drop or two of high-quality embroidery machine oil daily or every few hours of operation.
4. If issues persist after cleaning and lubrication, consider replacing the entire rotary hook assembly.

We stock high-quality replacement rotary hooks compatible with Barudan BEVT series machines.

3. Thread Trimmer Blades (Fixed and Moving) high likelihood

How to tell

Inconsistent thread trims, partial trims, or threads not trimming at all. Excessive thread tails after a trim. Visible dullness or nicks on the blade edges.

Fix

1. Inspect the fixed and moving trimmer blades regularly for sharpness and damage. Refer to the '02 Thread cut' section of your parts book.
2. Clean the trimmer area of lint and thread buildup.
3. If blades are dull or damaged, replace both the fixed and moving blades simultaneously for optimal performance. Ensure proper alignment after replacement.

4. Thread Path Components (Tension Discs, Thread Guides) medium likelihood

How to tell

Frequent thread breaks, inconsistent tension, or poor stitch quality. Visible grooves, burrs, or wear on tension discs, thread guides, or take-up levers. Refer to '03 Take up lever' and '06 Thread guide' sections.

Fix

1. Clean all thread path components (pre-tensioners, main tension discs, thread guides, take-up lever) daily with a soft brush or compressed air.
2. Inspect for any nicks, burrs, or grooves that could snag or fray thread. Smooth minor imperfections with fine-grit sandpaper or replace the affected component.
3. Ensure tension discs are clean and move freely, and that the take-up lever operates smoothly without obstruction.

5. Needle Bar Driver Fixing Base Block medium likelihood

How to tell

Excessive play or wobble in the needle bar, inconsistent needle depth, or unusual noise from the needle bar area. Poor stitch registration or needle breaks. Refer to '04 Needle bar' sections.

Fix

1. Periodically inspect the needle bar driver fixing base block for signs of wear, cracks, or loosening.
2. Ensure all screws securing the block are tight. Refer to your machine's manual for specific torque settings.
3. If significant wear or damage is present, replace the Barudan HT230290 Needle Bar Driver Fixing Base Block for BEAT, BEVT, BEDT, BENZ, BEXY Series to restore proper needle bar stability and movement.

6. Drive Belts (Pantograph, Head Drive) low likelihood

How to tell

Squealing noises, inconsistent pantograph movement, skipped stitches, or poor registration. Visible fraying, cracking, or stretching of belts. Refer to '08 Drive' and '10 Pantograph drive' sections.

Fix

1. Inspect all drive belts (pantograph X/Y, main head drive) for tension, wear, and damage every few months.
2. Ensure belts are free of debris and properly aligned.
3. If a belt shows signs of wear, stretching, or damage, replace it. Consult your machine manual for correct tensioning procedures.

Parts involved: Belts, pulleys & gears →

7. Integrated Stepper Motor Driver low likelihood

How to tell

Erratic or no movement from a specific motor (e.g., color change, pantograph axis), motor overheating, or error codes related to motor drivers. This is often a sudden failure rather than gradual wear.

Fix

1. If a motor is malfunctioning, first check its wiring connections for looseness or damage.
2. If the motor itself is confirmed to be working (e.g., by swapping with a known good motor or testing), the integrated stepper motor driver may be faulty.
3. Replace the faulty driver. Ensure the replacement is compatible, such as the IHSS57-36-10-RC/EC Nema23 1.2Nm Integrated Stepper Motor Driver, if applicable to the specific motor experiencing issues.

We stock the IHSS57-36-10-RC/EC Nema23 1.2Nm Integrated Stepper Motor Driver for Tajima, Barudan, Ricoma, HappyJapan, SWF.
