SunStar KM-380 BL-B cylinder arm consistently leaking oil

[flashman1207]

Hi there, I have the non-synchronized Binder version of this machine and have exactly the same issue with leaking oil (i think it may just be a crappy design) so now i just use a spray occasionally in the red holes. I also get the binding issue, however mine is when the needle is approaching the lowest position. i also have a problem where the main foot does not contact the fabric, regardless of thickness, when i put the foot down manually but then when the machine is going it seems to adjust somehow and grip the fabric....

Hello guys! I see that many of you are familiar with the Sunstar KM380bl-b topic I came across a machine quite by chance in the hope of buying a machine that sews a thicker thread, but it cannot sew thread 10 like my Adler 107. Does anyone know what thread thickness this machine can do? I produce holsters and hunting equipment that's why I need it to be able to sift with a thicker thread

The Sunstar KM-380 BL-B can take a max needle size of a #23 needle which basically means you can use a max size thread of V138 ( Tex 135, M20 ) thread in thinner leather.

Here is a link to the machines specifications. ( https://www.manualslib.com/manual/970676/Sunstar-Km-380bl.html?page=8#manual )
