20 Most Recent Singer CG550 Mechanical Sewing Machine Questions & Answers

You didn't explain the symptoms. Is the thread bunching, looping, knotting under the fabric? Is the bobbin thread rising to the top of the fabric? If it is bunching under the fabric, it is probably what is called thread nesting or bird nesting. There are several fixes, sometimes more than one fix is required to resolve the issue. Be sure to clean under the needle plate, around the bobbin, and the feed dogs. If the machine has instructions for oiling, follow the directions using a fresh, good quality sewing machine oil and apply only 1-2 drops each spot. Install a brand new needle. Make sure you are using a needle compatible with the thread and fabric being used. All About Needles Best practice is to use the same thread in both the upper and bobbin. Also, avoid old or bargain bin thread. Spend an extra couple of dollars to reduce frustration and increase success with your machine. If you wish, you may use two different colors of thread to test so you can easily determine what is happening with the tension. Remove the thread from the machine. RAISE the presser foot and rethread from the beginning--the thread needs to be seated firmly in the tension disk. Verify that the correct thread path is followed (consult the owner's manual). Set the upper tension to the midway point between high & low numbers (this is the factory standard and is a good place to start, but every machine is different and may need adjustment). Confirm that the bobbin is installed in the bobbin case (turning the correct direction) and that the bobbin case is threaded properly. Before beginning to stitch, hand rotate the handwheel one rotation and pull the bobbin thread to the top of the fabric. Then, gently hold the thread tails in the left hand and slowly begin to stitch. Test. If thread is bunching, looping under the fabric, the upper tension is too loose. Tighten it and retest. On most machines, the lower the tension number, the looser the tension. If the bobbin thread is rising to the top of the fabric, the upper tension is too tight. Loosen the upper tension and retest. Keep adjusting and testing until it is where you want it. Generally, tension is correct when both threads (upper & bobbin) meet in the middle of the fabric. FWIW, tension is static and should be tested and readjusted every time a new project is begun. The needle, thread, and fabric will affect the tension, so it is important to get comfortable adjusting the tension. Also found the following reviews.

Several things can cause skipped stitches. Incorrect Tension, Dull needle, Wrong type of needle, Machine Timing.

To do it properly you'll need the service manual. You can buy one (it's dowloadable!) here: http://www.sewnotretail.com/service-manual-for-singer-commercial-grade-cg500-cg550-cg590-sewing-machine/ I was having the same problem and this worked out beautifully. I also adjusted the needle drive shaft height before I reset the timing. While you're at it, check the hook timing belt tension.

my CG550 is running very slow I need help?

Try rethreading the top thread thru the tensioner. Make sure the presser foot is in the up position during threading, and as you go thru the tensioner you may need to pull the thread back and forth lightly to help it settle in the tension discs. Also check the type of bobbin being used. Drop in bobbin machines need bobbins with rounded sides (class 66).

if you have a top bobbin winder that is jammed the only way to f ix it if you can't replace it is to put some WD40 on the spindle and let it soak down then put an electric drill over the spindle and switch on slowly and it should free off, if it just not catching to wind a bobbin you may need to replace the winder rubber which means getting inside the machine

Make sure you have the correct bobbin, 66 class. Check the bobbin case. These machines use the apollo bobbin case that tend to get broken and then the thread hangs up.

Your bobbin is not installed correctly.There should be an excess thread coming out of the bobbin. Second-the thread wheel is the other way around,it should be positioned to follow where the extra hair of thread is to be going.And once you insert it in you'll notice a snap and the bobbin is settled firmly and locked into the shaft.

Possible bent or wrong needle. If ok, check the zig-zag mechanism to see if it has come uncoupled from the needle mechanism. Good luck!

Presser Foot Release Lever: First, check if the presser foot release lever is functioning properly. Sometimes, it may be stuck or not engaging correctly. Make sure it moves freely and isn't obstructed. If it's not working, try slackening the presser foot tension using the dial on top of the machine. If that doesn't help, you might need to adjust the presser bar slightly. Presser Bar Adjustment: If the presser bar was loose to begin with, completely slacken off the pressure. Put the presser foot up using the lever, then slacken off the screw on the bar and adjust the presser bar as needed. Handwheel Stuck: If the handwheel is stuck, it could be due to issues with gears, cams, or other internal mechanisms. Inspect the machine's casing or access panel for any signs of damage, such as broken teeth on gears or misaligned cams. Thread Take-Up Lever: If the take-up lever isn't moving up and down even when you manually turn the handwheel, check the hand clutch. Tighten and adjust the inner portion of the wheel on the right side of your machine and the hand clutch. If these don't do the job, you might consult Singer's customer service or a repair shot.

Inspect the Stitch Width Control: The stitch width control determines how wide the zigzag stitch is. If it's set to a wide zigzag, the machine will remain in that mode. Adjust the stitch width control to the narrowest setting (usually zero) for straight stitching. Clean and Lubricate: Dust, lint, or debris can interfere with the machine's mechanisms. Turn off the machine, unplug it, and clean the bobbin area, feed dogs, and needle plate. Lubricate any moving parts according to the manufacturer's instructions. Check the Needle Position: Make sure the needle is centered. If it's off-center, the machine may default to zigzag mode. Adjust the needle position if needed. Test with a New Needle: A bent or dull needle can cause stitching issues. Replace the needle with a new one and ensure it's compatible with your machine. Reset the Machine: Turn off the machine, unplug it, and wait for a few minutes. Then, plug it back in and turn it on. This can sometimes reset the internal settings. Consult the Manual: Refer to your Singer 312 sewing machine's manual for specific troubleshooting steps related to zigzag issues. The manual may provide additional insights or solutions.

If both the needle and the hand wheel on your Singer 140Q sewing machine are jammed, it indicates a more serious issue that likely requires attention. Here are some steps you can take to troubleshoot and possibly resolve the problem: 1. Turn Off the Machine: Start by turning off the sewing machine and unplugging it from the power source. This ensures safety while you troubleshoot the issue. 2. Check for Obstructions: Inspect the area around the needle and hand wheel for any obstructions such as broken needles, tangled thread, or debris. Remove any obstructions carefully. 3. Rotate the Hand wheel: Gently try to rotate the hand wheel manually. If it's stuck, avoid forcing it as this could cause further damage. Instead, try to identify what's causing the jam by examining the mechanism closely. 4. Inspect the Bobbin Area: Open the bobbin case and remove the bobbin. Check for any tangles of thread or debris that could be causing the jam. Clean the bobbin area thoroughly. 5. Check the Needle: Remove the needle and inspect it for any damage. Replace the needle if it's bent, dull, or damaged in any way. 6. Oil the Machine: Lubrication is important for smooth operation. Apply a drop of sewing machine oil to the moving parts, such as the hand wheel shaft and other points indicated in your machine's manual. 7. Professional Inspection: If you're unable to resolve the issue on your own, consider taking your sewing machine to a qualified technician for inspection and repair. They can diagnose the problem accurately and perform any necessary repairs. Attempting to force the machine to work when it's jammed can potentially cause further damage. So, proceed with caution and prioritize safety while troubleshooting the issue.
