Bobbin Winding System
The Bernette B77 features a convenient top-loading drop-in bobbin system. To wind a bobbin, place the thread spool on the spool pin and guide the thread through the designated tension disc. Secure the thread end into the bobbin, then engage the bobbin winding shaft.
Press the foot pedal gently to begin winding; the machine automatically stops when the bobbin is full. Consistent bobbin winding ensures even stitch formation. Regularly check the bobbin thread for tangles or uneven winding. A properly wound bobbin is crucial for optimal sewing performance and preventing thread nests.
Basic Operation: Threading the Machine
Correct threading is fundamental for successful sewing with the Bernette B77. Begin by raising the presser foot and thread spool pin. Guide the thread through the first thread guide, then down and around the tension disc, ensuring it seats correctly. Continue threading through the take-up lever and down to the needle clamp.
Finally, thread the needle from front to back. Simultaneously, wind thread around the bobbin and insert it into the bobbin case. Always double-check the threading path against the machine’s diagram. Proper threading prevents skipped stitches and ensures smooth operation.

Adjusting Stitch Length and Width
Precise control over stitch length and width is crucial for achieving professional results with your Bernette B77. These adjustments directly impact the fabric’s appearance and durability. Typically, shorter stitch lengths are best for delicate fabrics and curves, while longer lengths suit heavier materials and straight seams.
Width adjustments alter the zigzag pattern’s breadth, influencing decorative stitch designs and seam finishing. The B77 features easy-to-use dials or buttons for quick adjustments; Always test your settings on a scrap fabric before starting your project to ensure optimal stitch formation and prevent puckering or breakage. Mastering these controls unlocks the machine’s full potential!
Needle and Presser Foot Selection

Choosing the correct needle and presser foot is paramount for successful sewing with the Bernette B77. Different fabrics require specific needle types – universal, ballpoint, stretch, or even leather needles – to prevent damage and ensure smooth stitching. The presser foot plays a vital role in fabric feed and stitch formation.
The B77 supports a variety of presser feet, each designed for a specific task, like zipper insertion, buttonholes, or quilting. Refer to your manual for guidance on matching the right foot to your project. Incorrect combinations can lead to skipped stitches, fabric bunching, or needle breakage. Experiment to find the optimal setup for each material!
Using the Reverse Stitch Function
The reverse stitch function on your Bernette B77 is crucial for securing seams at the beginning and end of a stitch line. This prevents unraveling and adds durability to your projects. Typically, a dedicated reverse button or lever activates this feature. Pressing it allows you to sew backwards over existing stitches.
Experiment with the length of your reverse stitching – a short back tack is usually sufficient. Excessive reverse stitching can create bulkiness. The B77 may also offer a reverse stitch setting to automatically add back tacking at the start and end of each seam. Consult your manual for specific instructions on utilizing this automated function for consistent results.
Troubleshooting Common Issues

Encountering problems with your Bernette B77 is normal; here’s how to address frequent issues. Thread breakage often stems from incorrect threading, a dull needle, or improper tension. Re-thread the machine carefully, replace the needle, and adjust the tension dial. Skipped stitches can indicate a bent needle, incorrect needle size for the fabric, or issues with the presser foot pressure.
Always use the correct needle type and size. Ensure the presser foot is firmly in place. If problems persist, consult the manual’s detailed troubleshooting section or Bernette’s online resources for further assistance and potential solutions.
Thread Breakage
Frequent thread breakage on your Bernette B77 can be frustrating, but is often easily resolved. First, meticulously re-thread the entire machine, ensuring the thread is properly seated in all guides and the tension discs. A dull or damaged needle is a common culprit – replace it with a new, appropriate needle for your fabric type.
Incorrect thread tension is another key factor; experiment with slight adjustments to the tension dial. Finally, verify you’re using quality thread and that the bobbin is wound evenly. If the issue continues, consult the manual’s diagrams for correct threading paths.
Skipped Stitches
Encountering skipped stitches with your Bernette B77? Several factors could be at play. Begin by ensuring the needle is correctly inserted – it should be fully pushed up into the needle clamp. A bent or damaged needle must be replaced immediately. Confirm you’re using the correct needle type and size for your chosen fabric weight; heavier fabrics require stronger needles.
Also, check the presser foot pressure; insufficient pressure can cause skipped stitches. Finally, re-thread both the upper thread and the bobbin, verifying proper tension. If problems persist, a timing issue might require professional servicing.
Maintaining Your Bernette B77
Regular maintenance ensures your Bernette B77’s longevity and optimal performance. Consistent cleaning is paramount; remove lint and dust from the bobbin area and feed dogs after each use. A small brush is ideal for this task. Avoid using compressed air, as it can push debris further inside.
Periodically, oil key lubrication points as outlined in the full manual – typically around the bobbin hook and motor. Never over-oil. Proper care prevents issues and keeps your machine running smoothly for years of creative projects. A well-maintained machine is a happy machine!
Cleaning the Machine
Keeping your Bernette B77 clean is crucial for smooth operation. Begin by powering off and unplugging the machine. Use a soft brush to remove lint and thread debris from the bobbin area, feed dogs, and around the needle plate after each sewing session. A lint brush is particularly effective.
For tougher buildup, a slightly dampened (not wet!) cloth can be used. Avoid using compressed air, as it can force dust into sensitive components. Regularly cleaning prevents jams, skipped stitches, and ensures consistent stitch quality. A clean machine is a reliable machine!
Oiling and Lubrication
Proper lubrication extends the life of your Bernette B77. However, avoid over-oiling, as excess oil attracts dust. Only use sewing machine oil specifically designed for this purpose. Apply a small drop to the designated oiling points – typically found in the bobbin area and along the main shaft – as indicated in the machine’s diagram.

Refer to your manual for precise locations. Lubricate sparingly, and wipe away any excess oil immediately with a clean, lint-free cloth. Regular, minimal lubrication ensures smooth, quiet operation and prevents wear and tear on internal components. This simple maintenance step safeguards your investment.
