I lubricated the mechanism as part of my testing, but it didn't make any difference. Also as part of my testing, I found the part at the top, which, when pressed in with a screwdriver, allows the arm to rise. I guess this is the locking mechanism. But the lock doesn't seem to release the arm when power is applied, although it moves easily with screwdriver pressure, with or without power applied.
Is there anything further that people could suggest?
