I was using my 1200 in temperatures in the teens last night, and was
getting a lot of shuddering and squealing and other ungodly noises
when slewing in RA.
I went out this afternoon to fuss with it; adjusted backlash, etc.
with no luck.
Then I noticed that three of the four clutch knobs were tight, and one
was loose. I tightened them all and it SEEMS as though the problem is
I'm wondering if anyone can confirm that unevenly tightened clutch
knobs can cause the problem I had! It would make me feel much better!!
