Singer SICO34H User's Manual

To thread the Singer SICO34H, first raise the presser foot to release tension discs. Guide the thread from the spool through the thread guide, then down and around the tension disc. Pull it up to the take-up lever and then down to the needle, threading from front to back.
If the machine skips stitches, check if the needle is bent or dull and replace it if necessary. Ensure the needle is the correct size and type for the fabric. Also, re-thread the machine and check the tension settings.
Regular maintenance involves cleaning the lint from the bobbin case and feed dogs using a small brush. Oil the machine as per the manual's instructions and ensure it is unplugged during maintenance.
For denim fabric, use a heavy-duty or denim needle, usually size 90/14 or 100/16, to accommodate the thickness of the fabric.
To adjust the tension, use the tension dial located on the front of the machine. Higher numbers increase tension and lower numbers decrease it. Test on scrap fabric to find the correct setting.
Unusual noises may indicate a need for cleaning or oiling. Check for any obstructions in the bobbin area and ensure the machine is threaded correctly. If noises persist, consult a professional technician.
To fix a jammed bobbin case, first turn off the machine and remove the needle plate. Carefully remove any tangled thread and reinsert the bobbin case, ensuring it fits snugly. Re-thread the bobbin afterwards.
Yes, you can sew stretchy fabrics with the Singer SICO34H. Use a stretch needle and a zigzag stitch or a stretch stitch setting to accommodate the fabric's elasticity.
Store your Singer SICO34H in a dust-free environment with a cover to protect it from dust and moisture. Unplug the machine and keep it in a dry, cool place.
To change the presser foot, raise the presser foot lever and press the release lever at the back of the foot holder. Align the new presser foot with the holder and lower the presser foot lever to snap it into place.
