Pfaff 545 H4 Mechanics Manual

[Jeff Claridy]

I’m looking for a mechanic’s manual for my Pfaff 545 H4. I’ve downloaded and bought different manuals but they all fall short usually users manual. I’ve tried the 1245 mechanic’s manual but I can’t get the numbers to line up with the 190 needle system. Please advise

Have you tried this manual, which has a supplement at the end?

Yes I have that one. Here’s the exact problem I’m having, not having the measurement of the standard needle bar height for the 545 and trying to use the 1245 manual which says 15mm for the standard position before fine tuning. But I can’t find the measurement in my 545 instruction manual or my 145 instruction manual. But my manual on a Consew 226 says the height mine is set at when timed with the hook 22.3mm so I’m guessing it’s right but I’m still having thread cutting and jamming with thread issues and I’m just hand cranking when checking it. I also have a Juki 1508 that also is 22.3mm but it uses the 35 needle system or size. I’m a novice sewer and learning how to work on them as I go. But using 4 different manuals to setup one machine is insane. Any help would be greatly appreciated. Thanks for your response.

I have few pfaffs in the range of 142 to 1245 and I always adjust needle bar height regarding to the hook.

- get the needle bar into the lowest position

- advance so the needle bar rises to the necessary height regarding the model (between 1.6 - 2.5 mm)*

* first I was doing this with making a black mark on the needle bar, later I bough the clamps for that

 

- in this position the top of the needle hole must be 1 mm bellow the hook point

see pages 9-10 here in the attached manual.

Whenever I had serious problems I followed the manual from the beginning to the end and it always helped.

p.s. manuals sold on the internet are usual exactly the same as the free one.

Thank you, I haven’t seen this one yet. I like the illustrations and that clamp would definitely help. I like the way it takes you step by step in order for every previous adjustment to affect the adjustment you’re making next. Like a factory setup. Maybe all the ones for 545 H4 are in German? Thank you again.

If you are still looking for how much needle bar rise, these excerpts from pages 3 and 4 of the supplement may be useful.

Thanks. Right here in your supplement I don’t know where to find what model (A through D) the 545 H4 falls under?

It will be the first character on the second line of the brass plate on the front of the machine.
Mine said:

    545-H4-6/01
    CLPMN

So mine was a "C".

This introduction to the pfaff numbering system explains what all the characters mean: https://leatherworker.net/forum/applications/core/interface/file/attachment.php?id=166325
