Did you use the .89 mm A/F Hexagon wrench that comes with the 309?
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.
