Woolies Report post Posted November 20, 2019 I've got a Brother LS3-C51 but for the life of me cannot find a manual. I know there are some similar machines out there (techsew, consew, etc...) and I've found info on those ones which has been helpful but my machine has a few different parts and I am wondering what these are. Maybe it's an easy answer from some of you experts but I'm a newbie. I've attached a photo with arrows indicating the 2 parts. The black one turns and has a white divot dot on top. And the silver one screws up and down. What are these for and do I need to oil them or set them or??? If anyone does know where to get a manual I would greatly appreciate it! Thanks so much!

Wizcrafts Report post Posted November 21, 2019 Most likely the big black thumbscrew is the primary rear foot pressure spring adjuster. The spring would be a long, flat, heavy steel spring running inline with the back of the machine. The adjuster on top of the head is probably to fine tune the pressure on the inside foot.

Gregg From Keystone Sewing Report post Posted November 24, 2019 Consew 255RB Owners manual See above, black dial is part of the lubrication system, the silver knob is fine adjustment for the presser foot pressure. Quote Share this post Link to post Share on other sites
