How do I PUT together the presser foot. the part that snaps into foot

That depends on which of the presser foot designs you are dealing with. For all presser feet, lift the presser bar to the highest level before removing the foot. For the snap-on foot, push up on the toe (the front of the presser foot) as high as it can go until the foot releases from the clamping shank. When you put on another foot of this type, you line up the foot on the needle plate and lower the presser bar. Press down on the presser foot thumb screw on the presser foot shank as you lock in the presser foot.

For one-piece presser feet, loosen the thumb screw and let the foot down. Then tighten the thumb screw around the shank of the next presser foot. On the super-high bar shank feet, you must push down the presser foot lock to detach the foot. See page 23 (page 24 of the PDF) of the manual for the presser foot attachment details. Sears Parts Direct currently has the manual here: https://c.searspartsdirect.com/mmh/lis_pdf/OWNM/L0909123.pdf .

I hope this helps.

If the presser foot isn't connected to the presser foot shank, place the foot under the center of the shank. Lower the presser foot lifter making sure that the shank goes over the presser foot pin. Press down firmly on the screw that holds the presser foot shank until you hear the foot snap into the shank. Do not turn the presser foot shank screw. See the pictures on page 9 of the manual (page 11 of the PDF). Manuals LIb has this page here https://www.manualslib.com/manual/470415/Singer-7033.html?page=11#manual . The manual is also available from Singer on their support page: https://www.singer.com/support . The direct link to the manual is https://www.singer.com/sites/default/files/product_manual/SINGER%207029_7033_%207035%20and%209410%20Sewing%20Machine.pdf . For feet that are attached to the slant shank, you loosen the presser foot shank screw. Place the shank over the presser foot screw and then tighten the screw to hold the presser foot. If you removed a foot and the shank together, put it back on. Make sure that the needle and the presser foot lifter are in their highest positions. Push up the front side (toe) of the presser foot until the foot snaps off the shank.

If the presser foot doesn't snap into place, make sure that you have everything aligned properly. Otherwise check for damage to the presser foot and the shank. Replace any damaged parts. Some presser feet are available here: https://www.sewingpartsonline.com/singer-7033-sewing-machine-parts.aspx .

I hope this helps.

Make sure--Does the machine take a short shank presser foot? If so, you can replace it with a short shank zig-zag presser foot. You can probably go to a regular sewing machine repair shop and find a replacement presser foot.

**NOTE--the links below are examples of what is available. I cannot vouch for these vendors as I've never purchased from them. Do your own due diligence before purchasing!!!

Here's an open toe presser foot:

or a regular zig-zag foot:

OR you can buy a short shank adapter and a kit of snap-on presser feet that will give you a big variety of different kinds of presser feet, probably including a zipper foot, hemmer foot, 1/4" quilting foot, darning foot, teflon foot, etc....(probably more than she will ever use!) The snap-on kits are available online, try eBay or some of the other sites. They most likely are not Singer brand, but are most likely generic. However, if your granddaughter is just learning, this may be the broadest variety of choices.

These are examples of snap-on presser feet available.

It is most likely the presser foot you are trying to install was not made for your machine. There are so many machines available and most of those machines have their own presser feet, which are not interchangeable. Unfortunately, even a Singer presser foot is not interchangeable with other Singers. Some have screw attachments, others have lever attachments, some have long shanks, others have short, some are straight, others are slanted. You need to figure out what style presser foot your machine takes and then search for either the presser feet that fit or a shank adapter that you can then use snap-on feet (kits are available on eBay).

You need a special foot for free motion quilting--it is slightly shorter in height than a regular presser foot, which essentially provides space between the presser foot and the needle plate to manually move the fabric. Sometimes machines came with a standard darning foot accessory. Your Pfaff dealer probably has at least one style in stock. But there are other specialty feet you can probably use, ie Big Foot, clear free motion foot, C-shaped, oval, etc. You can also purchase a shank adapter (verify it is the correct shank for your machine) and use it with a kit of snap-on presser feet so you can have a variety of presser feet for different functions.

You first need to determine which shank the presser foot uses on your machine. You can compare your shank (current presser foot) with these photos to see which one your machine uses.

NOTE: If you purchase a snap-on presser foot, you will also have to buy a "shank adapter" that will attach the presser foot to the needlebar. Here are some pictures of snap-on adapters:

However, you will still need to make sure to buy the correct adapter for your machine. The GREAT thing about buying a snap-on adapter is you can add a lot of presser feet to your sewing machine accessories because you can purchase additional snap-on presser feet or even a complete set of snap-on feet that will all work with your adapter and your machine!!!

You will just snap one foot off and snap another on!!! Great idea!!!

OR--you can take your current presser foot along with the make & model of your machine and check with the local sewing repair shops to see if they have what you need.

FYI, once you know what shank your machine has, you can probably also find other specialty feet for your machine, ie walking foot, free-motion foot, etc.

the buttonhole foot snaps on to the presser bar, there's a little lever at the back of the presser bar that releases the foot, then put the buttonhole foot down on the needle plate & use the presser foot lifter (number 11) to lower the presser bar down onto the buttonhole foot & you'll hear a click sound when it snaps on & make sure to use the buttonhole lever(number 31) because the machine won't sew a buttonhole unless that lever is pulled down.

there are 2 type of presser bar foot clamps
one allows you to snap on the foot--raise & then lower the presser foot holder until the cut out is directly above the pin on the foot,,as you lower the presser foot holder the presser foot will automatically engage when put down on the pin area

the second is a shank & foot combined & there is a screw on the presser bar,,unscrew it some & put the shank up around the screw & retighten the screw

Turn power switch to "0"
raise the needle to highest position by turning the wheel toward you(counterclockwise) and raise the presser foot lever
release the foot by raising the lever located at the back of the presser foot assembly
place a different presser foot on the needle plate so that the bar on the presser foot is in line with the slot on the shank
lower the presser foot lever and fix the presser foot onto the shank. If the p foot is in the correct location the bar will snap in you should hear a click or snapping sound let me know if this helped thanks! amy

Not shure you can embroider on an MC4000, i think this is only a sewingmachine.

But to change presser fot:

If it a "snap on" foot, when foot lifted, press the "button" on the back of the needle bar (on the bottom) this would release the presser foot.

If is a large foot, you have to unscrew the screw on the left side of the needlebar, and change the whole foot.
