To ensure your Poolin EOC06 embroidery machine runs smoothly over the long term, avoids malfunctions, and delivers high-quality embroidery results, this official tutorial demonstrates the key steps for daily machine maintenance.

• Poolin EOC06 Computerized Embroidery Machine

• Small cleaning brush / mini brush
• Soft cloth or lint-free cloth
• Sewing machine oil(Do not use low-quality or inferior lubricating oil)
• Screwdriver

Before starting any maintenance: 

1  Turn off the machine power.

2  Ensure the machine is completely disconnected from the power supply.

3  Prepare all cleaning and lubrication tools.

(This is an essential prerequisite to ensure safety and prevent damage.)

The machine head is the most active part of the embroidery machine and also the area where thread lint and dust accumulate most easily:

• Loosen the screws on the back of the machine and remove the cover; 

• As shown in the image, apply oil to these 8 points, once per month, 2 drops each time; 

• Locate the round cover under the handle, remove it, and add 4–5 drops of oil into the hole each month;

• Rotate the handwheel twice to fully lubricate the needle bar and presser bar;

• After oiling, wipe off excess oil to prevent fabric staining or damage;

• Reinstall the cover and ensure all openings and the head cover are properly secured.

Recommendation: Perform a quick cleaning after each use to prevent leftover thread debris from affecting embroidery quality.

The rotary hook is the core component that controls bobbin thread movement:

• Remove the transparent cover and needle plate; 

• Remove the bobbin case and use a brush to clean dust or broken thread debris around the rotary hook;

• Add 3 drops of oil into the central oiling hole;

• Reinstall the bobbin case and bobbin cover.

Tip: If thread jamming or skipped stitches occur frequently, this area is often the main cause.

The Y-axis guide rail controls the front-to-back movement of the embroidery hoop:

• Unscrew the fixing screws at both ends of the Y-axis; 

• Add 3 drops of oil into the felt pads on both sides of the guide rail;

• Maintenance is recommended once every three months.

Similar to the Y-axis, the X-axis guide rail controls the left-to-right movement of the embroidery hoop:

• Stand the machine upright, loosen the six screws at the bottom, and remove the base plate;
• Add 3 drops of oil to each sliding pad on the main shaft and X-axis guide rail;
• Maintenance is recommended once every three months.

Key Point: Both guide rails should be cleaned before and after every large embroidery project.

At the end of the video, several important maintenance reminders are summarized: ✔ Avoid over-lubrication — moderate oiling is sufficient; excess oil attracts dust ✔ Clean areas where thread lint commonly accumulates — needle plate, felt pads, thread paths ✔ If the machine jams or makes unusual noises, stop operation immediately and inspect ✔ Regularly check that screws and components are securely fastened (These key points help keep the machine more durable and stable.)

• Regular cleaning is more effective than occasional deep cleaning

A quick cleanup of the machine head and bobbin area after each embroidery session can significantly reduce future issues.

• Lubricate only recommended locations

Over-lubrication or oiling incorrect areas may affect mechanical precision and stitch accuracy.

• Do not blow compressed air directly into the machine

Although it may seem convenient, compressed air often pushes dust deeper inside, leading to secondary buildup.

• Common embroidery problems are closely related to maintenance

Skipped stitches, thread breakage, and stitch misalignment are often caused by accumulated dust or improper lubrication.
