Singer 3860 Instruction Manual

To thread the Singer 3860, first ensure that the machine is turned off. Raise the presser foot lifter, and turn the handwheel to raise the needle to its highest position. Follow the threading path indicated on the machine, guiding the thread through the tension discs and take-up lever, then thread the needle from front to back.
If the Singer 3860 is skipping stitches, check the needle first. Ensure it is the correct type and size for your fabric, and that it is not bent or dull. Also, make sure it is inserted correctly. Re-thread the machine, ensuring that the thread is properly seated in the tension discs.
Regular maintenance of the Singer 3860 includes cleaning the bobbin area of lint and debris, oiling the machine as instructed in the user manual, and changing the needle regularly. Always unplug the machine before performing maintenance.
A jam in the Singer 3860 can be caused by incorrect threading, a tangled bobbin, or accumulated lint. Re-thread the machine and bobbin, check for tangles, and clean the bobbin area. Ensure the thread is correctly seated in the tension discs.
To adjust the tension on the Singer 3860, use the tension dial located on the front of the machine. For most fabrics, a setting of 3 to 5 is suitable. Test on a scrap of fabric and adjust as necessary to achieve balanced stitches without puckering.
To select different stitches on the Singer 3860, use the stitch selector dial. Turn the dial to choose the desired stitch, which is displayed on the machine. Adjust stitch length and width using the corresponding dials if needed.
Frequent needle breaks can be due to using the wrong needle size or type, improper needle insertion, or sewing through thick seams without the appropriate needle. Ensure the needle is suitable for the fabric and is correctly installed.
To wind the bobbin on the Singer 3860, place the thread spool on the spool pin and the bobbin on the bobbin winder spindle. Follow the threading path for bobbin winding, push the bobbin winder spindle to the right, and press the foot pedal to start winding.
Uneven stitches on the Singer 3860 can be caused by incorrect threading, tension issues, or a dull needle. Re-thread the machine, check and adjust the tension settings, and replace the needle if necessary.
To change the presser foot on the Singer 3860, raise the presser foot lifter and turn off the machine. Press the lever at the back of the presser foot holder to release the current foot. Position the new foot under the holder, lower the presser foot lifter to secure it in place.
