How do you adjust foot plate tension? - NRS Hoveround MPV 5 - Used Power Wheelchair

It is almost for sure tension adjustment.
1. Because there is higher tension on the bobbin you need to check it so it is allowing the thread to move with an adjustment equal to the top tension (at four).
2. Rethread the top while the pressure foot is up. The thread should move freely. Don't thread needle yet.
3. Set tension to four. Now, put pressure foot down. Pull on thread. Do you get a tug? You may want to move your adjustment just to give yourself an idea of how it changes. It should change while you adjust. Anyway, four is your best adjustment usually.
4. The idea is to equal the bobbin tension and the top tension. This must be correct. On yours you had a much higher tension on the bobbin. This caused the top thread to be gobbled up. Remember how important it is to equal the top and bottom tensions.

1. Replace thread with good thread. (Check by holding to light to see if there is fuzz).
2. Adjust the bobbin tension. The tension on top is set to three and the bobbin tension should be equal to this amount.
3. Replace needle.
4. Check the top tension with tension foot down to see if the thread can move or does it get stuck? If it gets stuck the tension control may need adjusted or cleaned.
5. Pull the bobbin thread above the throat plate and pull on the thread. It must have some tension but not get stuck.
TENSION TENSION TENSION IS THE PROBLEM!

it is possible that when threading the machine the thread has gone behind the tension plates and not between them
check and re-thread the machine to ensure that that has not happened

First, you will need to select a brand new needle of the type suitable for your fabric. Select a proper thread weight and type for your needle and fabric.

Select the proper presser foot for your project/fabric. On some fabrics, you may even want to use a straight stitch needle plate to prevent the fabric from going down the needle hole.

You will want to adjust the upper tension so that the upper and bobbin threads meet in the middle of the fabric.

Also, probably want to adjust the presser foot pressure so that the presser foot presses harder or lighter (depending on the fabric) so the fabric will feed through evenly, ie both the top and bottom fabrics move together at the same rate. Hint: if it is really thick, like sewing a quilt with batting, a walking foot may be helpful.

Be sure to test on scrap fabric from your project before beginning sewing your project together.

All About Needles

Why is there an extra needle plate supplied with my machine Brother straight stitch plate and presser foot cannot be used with zig-zag or decorative stitch or you will surely break your needle and possible knock the machine out of time!

Adjusting Sewing Machine Tension to Prevent Problems

Adjusting the presser foot pressure on your sewing machine

...

thread tension can be adjusted by the small screw that holds the spring plate on the bobbin carrier under which you have to pull the thread after the bobbin is placed in the carrier
a small movement is a lot of tension adjustment
if the thread is bunching up under the material ,that will be the needle thread tension and it needs to be tightened

check that you have the thread between the two plates that form part of the upper thread tensioner
when threading it is very possible to have the thread go behind a plate and get jammed on the adjuster thread
other than that loosen of the thread adjuster a bit

Tension depends on so many things. Material thickness, right size needle, thread,bobbin etc . If it is none of these things then you need a technician.Best wishes

Possibilities are:

foot pressure adjustment
tension dial adjustment
stitch elongation

If you can already identify the tension adjustment dial and this device is above the pressure foot, then I would gess it is the first one, foot pressure adjustment.

Many models don't have this but it was standard for many years on all machines, allowing you to control the pressure of the foot onto the needle plate, something you need to vary if you are sewing very heavy coatings or very fine silks, sometimes you just need to finesse the pressure yourself.

I found that sewing this type of fabric you should not have any pressure on the presser foot. and the top tension should be looser but note the tension before you adjust. and remember to make sure the needle is the right size for the fabric. and since wer are not to change the bottom tension because it always right?? then you may have to make the seam stitch longer good luck

1. Make sure you are using the correct needle and thread for type of fabric and it is installed correctly. Make sure bobbin is threaded evenly. 2. Tread path - make sure the machine is correctly threaded. Then, with your finger, feel for burrs, nicks or roughness on any metal parts that contact the thread. Open the slide plate, remove the bobbin and inspect the bobbin case and hook. Remove the needle plate and examine the needle hole. Sand any rough areas with fine emery paper and blow away grit. If burrs or nicks remain on the needle, presser foot, needle plate or bobbin case, replace them with exact replacement parts, if they remain on the thread guides, take-up lever, bobbin hook or tension regulator, take the machine for professional service. 3. Loosen thread tension by adjusting tension dial. 4. Clean feed dog, bobbin case, and tension discs. Unplug the machine. Use a small, stiff brush to wipe dirt and lint off the machine head and the needle bar area. Raise the presser foot and the needle to the highest position, open slide plate and remove the bobbin and needle plate. brush away dirt and lint from the feed dogs and bobbin case and remove any tangled thread with your fingers. Use a soft cloth to clean between the tension disc on the tension regulator. 5. Also check tension on presser foot
