I think I got the wrong machine :O

So long story short. I make and repair bags. mostly Louis Vuitton. Contacted a Adler reseller. Said I had a Pfaff 335, and she could not keep up with thicker threads. 20 (TEX 135) and needed an upgrade. 
So they sold me this beast of a machine. They assured me it was the right fit.
first problem I ran into, other then the machine only came with R needles. is that its not possible to get a 140 LR needle for the damn thing. and that is my go to needle for 20 thread. 

I dont mind overkill. but what other problems might I run into down the line? Sewing with bigger threads it not a problem oc.

This wouldn't have been my first choice of a machine mainly due to the hole it would punch through the material, 2.5mm diameter unless you are sewing items above 1/2"(12.5mm) in thickness or saddles. I would have probably gone with a Juki LS-1341 or clone with a speed reducer as it would use a smaller diameter needle the system 135 x 16 x needle size for leather. My understanding is the 969 is a class 441 machine that takes the system 7x 3, 794 or 1000 needles (Schmetz). There are needles available for 7x3 or 794 from #19-#27 (120-220) for V92 to V415 thread. 

I would talk to the dealer to track down the needles if you are going to keep the machine and maybe discuss exchanging the machine for something like a 869 which would take the system 135 x 16 needles .

One curse of the 7x3 needle system is they are so long. This means they will flex more when using narrow sizes like the 140Nm you mentioned.

The needles are also more expensive, and available from fewer sources.

I would have thought the 869 would be a better machine for the job also. thickest leather I will sew is 8mm.
