Brother GW3700 Quick Reference Guide

To thread the Brother GW3700, follow these steps: 1) Raise the presser foot lever and turn the handwheel towards you to raise the needle to its highest position. 2) Place the spool of thread on the spool pin and secure it with the spool cap. 3) Pull the thread and pass it through the thread guide, then follow the threading path indicated on the machine. 4) Thread the needle from front to back.
Ensure the feed dogs are raised and not set to the drop feed position. Check that the presser foot is lowered. If the problem persists, clean the feed dogs and surrounding area to remove lint or thread that could be obstructing movement.
Check the threading of the machine to ensure it's done correctly. Adjust the upper tension dial according to the fabric being used. For light fabrics, lower the tension and for heavier fabrics, increase it. Make sure the bobbin is wound evenly and installed correctly.
Regular maintenance includes cleaning the bobbin case and feed dogs after every project and oiling the machine once a month if it is used frequently. Refer to the manual for detailed instructions on oiling. Have the machine serviced by a professional annually.
Turn off the machine and raise the needle to its highest position. Loosen the needle clamp screw with a screwdriver and remove the old needle. Insert a new needle with the flat side facing the back and tighten the screw securely.
Ensure the machine is threaded correctly and the needle is not bent or dull. Check for any debris or lint in the bobbin area. If the noise persists, it may require servicing to check for internal issues.
Ensure the needle is the correct type and size for the fabric and that it is not bent or blunt. Re-thread the machine, ensuring the thread is properly seated in the tension discs. Check tension settings and adjust if necessary.
Check that the power cord is securely connected to both the machine and the power outlet. Ensure the power switch is in the 'on' position. If the machine still does not turn on, check the circuit breaker or fuse in your home. If the issue persists, contact a service technician.
To adjust the stitch length, turn the stitch length dial located on the right side of the machine. The numbers indicate the stitch length in millimeters, with a higher number resulting in a longer stitch.
Regularly remove the bobbin case and clean out any lint or thread debris. Use a soft brush or a vacuum attachment to clean the area. Check for any signs of wear or damage and replace parts as needed.
