Singer Industrial 191D Instruction Manual

To thread the Singer Industrial 191D, follow these steps: 1) Place the spool on the spool pin. 2) Draw the thread through the top thread guide. 3) Pull it through the tension discs. 4) Bring the thread through the take-up lever. 5) Continue threading through the remaining guides down to the needle. Ensure the needle is threaded from the front to the back.
If your Singer 191D is skipping stitches, first check if the needle is correctly inserted and not bent. Ensure you are using the appropriate needle size and type for the fabric. Re-thread the machine, making sure the thread is properly seated in the tension discs. Also, verify the bobbin is wound evenly and inserted correctly.
To adjust the tension on the Singer 191D, use the tension dial located on the front of the machine. Turn the dial to the right to increase tension and to the left to decrease it. Test your stitching on a scrap piece of fabric to ensure the tension is balanced and adjust as needed.
Regular maintenance for the Singer 191D includes cleaning the feed dogs and bobbin area, oiling the machine as specified in the manual, checking for loose screws, and ensuring the needle is sharp and correctly positioned. Regular maintenance helps extend the life of the machine and ensures optimal performance.
If the motor of your Singer 191D is making noise, it might be due to a lack of lubrication or a worn-out belt. Ensure the machine is properly oiled and check the belt for wear and tear. If the issue persists, consult a professional technician.
To change the needle on the Singer 191D, first turn off the machine and unplug it. Loosen the needle clamp screw and remove the old needle. Insert a new needle with the flat side facing away from you, push it up as far as it will go, and tighten the needle clamp screw securely.
If your fabric is not feeding properly, check if the presser foot is down and that the feed dogs are engaged. Clean the feed dogs to remove any lint or debris. Adjust the presser foot pressure if necessary and ensure the fabric is positioned correctly.
Thread bunching under the fabric can be caused by incorrect threading or tension issues. Re-thread both the upper thread and bobbin, making sure they are seated correctly. Adjust the tension settings and test on a scrap piece of fabric.
The Singer 191D should be oiled after every 8 hours of use or as specified in the user manual. Focus on oiling the moving parts, particularly the needle bar, presser bar, and hook area. Use sewing machine oil and avoid over-oiling.
To set up the bobbin on the Singer 191D, wind the bobbin with thread using the bobbin winder. Insert the bobbin into the bobbin case ensuring the thread is unwinding in the correct direction. Place the bobbin case in the shuttle, ensuring it is properly seated.
