Dear all, I have got my hands on a pfaff 561 with an efka variostop motor. I'm a true newbie with (industrial) sewing machines and I really didn't know much about the machine before purchasing and how to value it. I've come across the problem that the machine shuts off when I decrease the pressure on the footpedal (from fast to slow stitching). I don't know what happens, I can only explain it as the experience of lowering the speed in a (clutch) car and the speed becomes too low for the gear and the car finally shuts off. The efka motor of the sewing machine "stutters" and then finally shuts off as if it has short-circuit. I can't restart the motor up until (over) a minute later, before it starts and shuts off again. The seller told me the machine works on 220 Volt, but maybe not? Are the settings not compatible? I would really appreciate it if someone with the knowledge can give me an update on the do's and don'ts with the efka motor! Was this purchase a mistake? In the meantime I got my eyes on an Adler 67-73 L with a servo motor, though it is double the price. Would it make more sense to return the pfaff and invest in the Adler? I am situated in the Netherlands and don't work with leather but I make bags and wallets with waste tarpaulin.

Hi everybody! A year ago I aquired a Pfaff walking foot machine (335-H3-39/21-BSN to be exact) with a Variostop VD24. Now I managed to find the correct lamp for this machine with a separate arm. The lamp is outfitted with a small plug and a 230VAC 15W lamp, and when I went to install it on my machine I found out that the Variostop motor has a connection for a lamp already! But when I measured the contacts on the motor it gave out only 15VAC? So my question is, are these old (1976 is the vintage of my machine) machines usually fitted with 12VAC bulbs? The bulb is some odd bayonet bulb. Best regards, Sebastian

I am doing a little dance. Why? Well I found out today that my local saddle maker is selling a Durkopp Adler 205/370 or 374 that he has in his workshop, complete with an Efka Variostop motor/control system.The machine is likely to be well used,but not necessarily knackered. I get to find out the price on Thursday, when the owner will be "in".The previous one was around 1800 euros, sold last week.I suspect he is getting new machines, and the old ones will have long become "scrap price" from an accountancy point of view. I just have to make sure what I am buying is not real scrap, as Adler parts prices can be steeeeeeeeep! As it is a production machine, there is also air operated this and that.Not all of it works, but I will have to take those bits off (I really do not want to hear my compressor all the time), and replace them with original items. The motor may be 3 phase- it looked a lot bigger than any single phase one I have had- sort of bullet shaped.I suspect from pictures I have seen, the Efka is used with a clutch motor.. The manual states that the recommended Efka unit is either a type 9B 31, or an 8E 521. I found some details on the 8E 521. It has a pneumatic backtack console parked on top of the machine head. The Efka looks awful complicated- how useful/what can you do with it, assuming the system is quite old- no computer shaped boxes like the new ones. Underneath the machine table was a great jumble of boxes, air operation stuff, and wiring. Efka will be completely new to me. The 205 head is painted grey (any idea of year/s of manufacture?), and has a black end piece, with no cover for the arm that has thread going throughon its end. I noticed that the stitch length lever did not stay up when put in reverse, but I wondered if this had been disabled in some way for the air back tacking. Are there any particular checks pertaining to this specific model that I need to do? I have noticed comments on costing for a new bobbin case, plus checking for needle bar wobble and availability of the different needle size spacers pointed out in UWE's Youtube video. It is of course, already set up to sew a reasonably thick leather, so I can take some samples of what I use with me. I have the room and the time to play with this one, if the price is right.

The durkopp Adler 205/370 I am buying has an old Efka Variostop motor and controller. The controller is a type 6F62AV. I have absolutely no experience of these, and would like to know how they compare to a Ho Hsing motor, which I currently have fitted to my Adler 105/64. I do not have the money to spend on an up to date Efka.The variostop seems awful complicated. Is there any point using it if I do not use the pneumatic features, because I cannot stand the noise of a compressor?(Assuming my small compressor will do the job). I am not doing production work, and nothing in any quantity. There is also the problem of getting the 3 phase motor working on single phase- what is the best way of doing that?
