Dürkopp Adler 1767 Seams Middle Guide Instructions

To adjust the tension, first ensure the machine is threaded correctly. Then, use the tension adjustment knob located on the machine's front panel. Turn it clockwise to increase tension and counterclockwise to decrease tension, testing on a scrap piece of fabric until the desired stitch quality is achieved.
Skipped stitches can result from a variety of issues. Check that you are using the correct needle size and type for your fabric. Ensure the needle is not bent or dull. Also, verify that the machine is threaded properly and re-thread if necessary.
Unusual noises can indicate a need for lubrication or that parts are misaligned. First, check that all screws and attachments are tightened. Then, follow the machine's maintenance manual to lubricate the appropriate parts. If the noise persists, consult a professional technician.
To maintain your sewing machine, regularly clean the lint and dust from the bobbin case and feed dogs using a small brush. Oil the machine as specified in the user manual, focusing on moving parts. Regularly check for and replace any worn parts.
To change the needle, first turn off the machine. Loosen the needle clamp screw and remove the old needle. Insert a new needle with the flat side facing the correct direction (usually towards the machine's back), then tighten the clamp screw securely.
Use the correct needle and thread type for the fabric. Adjust the tension settings appropriately, and test on a scrap piece of the same fabric. Adjust the stitch length and width settings based on the fabric's characteristics to achieve optimal stitch quality.
First, check that the feed dogs are engaged and clean. Ensure the presser foot is down and applying the correct amount of pressure. If necessary, adjust the presser foot pressure using the machine’s adjustment knob or lever.
To set up the middle guide, attach it to the machine using the designated mounting points. Adjust its position so that it aligns with the desired seam width. Secure it in place, and test on a fabric sample to ensure it guides the fabric accurately.
First, check if there is a power supply issue or a blown fuse. Ensure the machine is not jammed with thread or fabric. Turn off the machine, clear any jams, and restart. If the problem persists, consult a technician.
Regular maintenance should be performed after every 10 hours of operation or after completing a large project. This includes cleaning, oiling, and checking for worn parts. More extensive servicing by a professional is recommended annually.
