T622r I have recently aquired a long arm quilter with the #T622R on the plate attached to the machine and wnat to know what brand this is and the value

You can do embroidery or you can do free motion. If you're quilting a quilt sandwich (fabric, batting, backing fabric), you probably want to do free motion quilting. Embroidery would work better on fabric (with a stabilizer) but without the batting and backing fabric.

For free motion, you want a free motion foot--your machine's manufacturer probably provided one in the accessory kit (called a darning foot) or there are many generic free motion feet available for purchase (ie Big Foot quilting foot...). The BIG difference with a darning foot or free motion foot is that the shank is shorter than other presser feet because there needs to extra space between the presser foot and the needle plate so the quilter can easily manipulate the fabric. Usually, free motion quilters will drop the feed dogs to avoid feed dog interference with the fabric's movement, however, some quilters don't drop the feed dogs--just whatever works best for you and your machine. In addition, I use a Supreme Slider on the sewing machine surface--a silicone mat that provides a slick surface to help the fabric move.

There are a lot of web sites and video tutorials on free motion quilting. Take some time to watch them and then practice, practice, practice! It's an acquired skill so the more you practice, the better you will be.

There should be a hole across the back of the walking foot (penetrates the walking foot usually from right to left, although some feet will have 2 guides--one for left to right, the other left to right) where the bar mounts and a screw to tighten and hold it in place.

According to the following web site, the feed dogs do not drop on this machine, Instead, there is a plate that covers the feed dogs:

So an American machine has imperial seam guides on the needle plate.

But the Euro Pro would be European and in metric so it has seam guides in metric widths, i.e. millimetres. 10 will be 10 millimetres, or 1 centimetre, 16 mm, 22mm.

A normal seam in metric is 15mm - in your land 5/8", the two are not quite the same but pretty close. This link http://convert.french-property.co.uk/ gives you a converter between the two systems.

A 1/4" is your standard piecing seam for the quilters and this is why many Australian quilters will buy a 1/4" foot so they can guide the fabric along the foot edge to get nice standard seams.

So you could break out some masking tape and a metric/imperial ruler and measure from the needle to the right and put a strip of tape onto your needle plate to mark your 5/8" dimension you are used to. Or use the 16mm seam marking which is very close anyway.

Hope this helps.

You have to unscrew the screw for the presser foot first. The walking foot will then fit. Use the same screw to attach the walking foot. Before you insert the screw, take the white handle on the walking foot and slide it on the screw arm for the needle. Now tighten the screw.

There is a slide switch on the underside of the back of the free-arm. The feed dogs will not immediately raise when you slide it, the machine must make a full rotation for it to engage.

slide the accessory case off; locate the feed dog lever on the back of the free arm. Slide the lever either to the right (down) or to the left (up).

I would start out by putting some cleaner (409) on a q-tip and run it everywhere the thread touches. Guides, tension discs, the under side of the needle plate gets missed alot. Around the hook casing. Then I would just keep sewing on scraps, I know this wastes thread but eventually it will clean itself. A very close zigzag satin stitch would work best.
