Help with an industrial machine

I recently found a too-good-to-resist opportunity on a Singer 20U73, and I bought it. Now I'm trying to train myself on the great differences between an industrial amd home machine. My biggest problem is this: when I depress the pedal to begin sewing I have to push it almost all the way to the floor, then it suddenly takes off almost wide open. Getting it to start more slowly seems almost impossible. It has a clutch motor. The book says it's a "tailor shop/drapery machine" so I'm almost certain it's designed for better speed control. Are there adjustments for this? I wanted to ask before I start randomly turning bolts and such. Thanks.

Fred, The treadle is adjustable up and down by the nut on the rod between it and the motor. On the motor just behind the pulley on the front side is a brass nut with a lock nut, (about 5/8" nut) loosen the locking nut and turn the longer one in a couple turns to adjust the clutch closer to the fly wheel. Be careful not to get to close or you will burn up the clutch cork. With time and patience you can learn to feather the treadle as to make it sew one stitch at a time. This takes practice. Also a smaller pulley on the motor will make the maximum speed slower.

Hi Ron This isn't to pushy I hope? you seem a knowledgeable chap, I have a kansia machine for elasticising waist bands and the tensions have gone potty, cant seem to find a service engineer or even a manual. have you any suggestions (except for I am too cheeky) TIA

To add to Ron's comment, did you know that if you bring your heel down it acts as a brake? Industrial machines have this feature, generally, so you don't want to push the pedal with your entire foot. Be sure you're just pushing with the toe end of your foot to make it "go".

It does take practice, but once you learn you never want to go back to a slowpoke home machine!

Another thing that will help greatly. Learn to help the starting with the balance wheel. Proper technique will make that machine easy to handle. I am so used to this, I do it with all my machines (except the serger)

Often tensions can become grooved or clogged with residue from the thread. Take them apart one at a time and inspect, clean , repair or replace any grooved parts.

Thanks to all of you! Ron, I made a few adjustments as you suggested and it works MUCH better now. I still have to practice and get the "feel" down, but it's much improved over yesterday. Thanks a million!

Many thanks Ron., will give that a go over the weekend. I had an idea to place a different colour thread on each spool to see which one is playing up would this work??? mooie

That should help isolate the trouble thread path.
