janome sewing machine maintenance manual

The Janome Sewing Machine is a precision-engineered device designed for various sewing applications, featuring multiple stitch patterns, automatic needle threading, built-in buttonhole functions, adjustable stitch length and width, drop feed for free-motion sewing, and comprehensive maintenance requirements. Below are key sections for safety, maintenance procedures, cleaning, lubrication, troubleshooting, and care instructions.

Maintenance Overview

Regular maintenance ensures optimal performance and extends machine lifespan. Key components requiring attention: needle system, bobbin case, feed dogs, tension discs, motor assembly, and electronic controls.

Routine Cleaning Procedures

Proper cleaning prevents lint buildup and ensures smooth operation.

1. Unplug machine from power source before cleaning.
2. Remove needle plate: Use screwdriver to loosen screws, lift plate carefully.
3. Clean bobbin area: Use small brush to remove lint and thread fragments.
4. Clean feed dogs: Use stiff brush to remove accumulated lint.
5. Wipe exterior: Use soft, dry cloth; avoid chemicals on plastic surfaces.
6. Clean tension discs: Run unthreaded cotton floss through discs.

WARNING! Never use compressed air as it can force lint deeper into mechanism.

Lubrication Guidelines

Use only Janome-approved sewing machine oil.

1. Identify lubrication points: Refer to machine diagram (hook race, bobbin case area, needle bar).
2. Apply oil sparingly: One drop per point; excess oil can stain fabric.
3. Run machine without thread: Operate briefly to distribute oil.
4. Wipe excess oil: Use clean cloth to remove any visible oil.
5. Test on scrap fabric: Sew on waste material to remove residual oil.

CAUTION! Over-lubrication can damage electronic components and stain projects.

Needle and Bobbin Maintenance

• Needle Selection: Use appropriate needle type and size for fabric.
• Needle Installation: Insert fully into clamp with flat side to back.
• Bobbin Winding: Ensure even winding without overfilling.
• Bobbin Case: Clean regularly and check for burrs or damage.
• Thread Quality: Use high-quality thread to reduce lint.
• Tension Testing: Always test on scrap fabric before projects.
• Needle Change: Replace bent or dull needles immediately.
• Bobbin Thread: Match bobbin thread weight to top thread.

Timing and Tension Adjustment

Advanced maintenance procedures for optimal stitch quality.

Timing Adjustment: Requires technical expertise; involves synchronizing needle and hook movement. Signs of timing issues: skipped stitches, thread breaking, uneven stitches.

Tension Adjustment: Upper tension controlled via dial; bobbin tension via screw adjustment. Balanced tension: Threads lock in middle of fabric layers.

Upper Tension: Turn dial higher for tighter tension, lower for looser. Bobbin Tension: Small clockwise turn increases tension; counter-clockwise decreases.

Motor and Electrical Components

Maintaining motor performance and electrical safety.

1. Check power cord: Inspect for fraying or damage before each use.
2. Motor brushes: Replace when worn to 1/4 inch length.
3. Foot control: Ensure smooth operation; clean contact points.
4. Circuit board: Keep free of dust and moisture.
5. Voltage: Ensure consistent power supply; use surge protector.

Tip: Unplug machine when not in use to protect electronic components.

Storage and Transportation

Proper storage prevents damage and maintains calibration.

1. Clean thoroughly before storage.
2. Cover machine to prevent dust accumulation.
3. Store in dry, temperature-controlled environment.
4. Transport in original case or padded carrier.
5. Secure all moving parts: Lower presser foot, cover needle.
6. Remove needle during long-term storage.
7. Store accessories in designated compartments.
8. Avoid extreme temperatures and humidity.

WARNING! Never lift machine by handwheel or thread spool pin.
