Try to spray deoxit first before taking apart. It'll penatrate movable parts when you jerk it like you do now.
Sticky SME series V arm lift...
Hello, Folks!
My tech question of the day: one of my SME series V arm lifts has gotten sticky; it won't descend on it's own anymore. I can push it down with my finger, and the lever will raise the arm, but down, not so much.
I understand this is a common problem, which, I believe, is caused by the hydraulic fluid drying out and becoming too thick. I've gathered that the remedy is to clean the reservoir (which, I think, they call the dashpot) and refill it with fluid. So that leads to the actual questions: how does this assembly come apart? What is needed to clean the old fluid out (solvent, etc)? What kind of fluid should it be refilled with? How much?
Thanks in advance your your help!
