Under the set screw there should be a nylon plug. It will not damage the metal can of the lift and gives a smooth motion. If you tighten down on it to hard you squash the plug and jam it in the hole. Back the grub screw out and wiggle the lift front to back to see if you can loosen the plug.
Help with SME 309 arm lift. Will not lower or rise.
Was trying to adjust the the height of the SME 309 arm lift; it was to high. I doing so I messed something up. The lift will not rise or lower now. I used a .9mm Allen wrench and inserted it into the proper hole and either through something serious off or damaged it. I can’t get it to rise and lower properly now. It actually rises a bit when it’s in the down position now.
