The adler 98 is definitely stronger than an berina 217 the feed dogs are much wider and its an stronger machine, verry useful for sails the adler 266 / 166 is for heavy needles and threads (needles 140-230) but like wiz says : for boat covers and other stuf which does not require zig zag an triple feed machine is better (i use an adler 167 for stuf like that) michiel

If you turn the machine by hand (slow) you can see if the stitch in reverse is longer or constabulary is right (my guess would be you are missing stitches in reverse...) regards michiel

Hi nick, i have an 98 too and never found a manual..... beware: on the back side there is a cover, if you open it you will find yourself with some loose parts! i just wanted to take a look but it toke me some efford to get everything back in place the right way (and with the timing right) but if its not working properly maybe some did the same and did not succed to get it right again. Kind regards michiel

Every time I need a part for an adler i think about you and your singers constabulary (but i still keep buying adlers)

ther are no timing marks, but when you put the neelde and hook in the right position for timing the hook you only have to put the belt on its place

this post was verry helpfull when i had to replace the timingbelt of mij adler 169 when I did it again with an adler 67 I made some photo's of how i got the belt through the gap....

Had to mount de drawer under the head to fit

Just Made two extra short tables (i stil have more heads than tables but this does help)

The post of an one-needle machine is significant smaller and you can sew closer to the edge (of the post)

If you cannot find an service manual i would try it with an other brand postbed sewing machine the adler 68 looks not verry different to me http://www.duerkopp-adler.com/commons/download/download-text-attachments/Vintage_Manuals_Adler/Manual_Adler_68.pdf if that doesnot work you could use the partsmanual for your machine and for the adler to find out how it is for your machine it might be a puzzle but if you print them all and do some close reading you can do it (for me this method works) http://www.duerkopp-adler.com/commons/download/download-text-attachments/Vintage_Parts_Books_Adler/68.pdf

I temporary took down the setup but Thuis Will give an idea:

Some more pictures

I made a case which fit an industrial sewing machine head the same way they are used for domestic sewing machines (just a litle bit bigger most of my adlers fit in it...

I have seen such an feet / device on an double needle adler 167 there is an picture of it in the adler 167 leaflett (page 5) http://www.duerkopp-adler.com/commons/download/download-text-attachments/Vintage_Leaflets_Adler/Leaflets_Adler_Class_167_part2.pdf Its a different machine but it gives an idea how this could work

My adler 69-373 likes thread 20 (which should be about 135 i believe) bottum adn upper thread. But its seems a machine with a lot of "historie" / pre owners so maybe someone tinkered a litle bit with it
