New to Losmandy - just received my first one today, an 811G and just doing some indoor tests after I assembled it.
I've noticed there seems to be quite a bit backlash in the DEC. I did tighten the clutch but still I can move the DEC by turning the counterweight shaft, and can even hear a sound when it moves, sounds like it is bouncing between gear teeth...
I understand this particular 'issue' has been reported probably too many times but still I'm a bit concerned - is this backlash normal, or I need to do some adjustments myself?
Yue,
Since you just received your mount, I'd recommend trying to use it first before making any adjustments. There will always be a little play in both axes. If it was set any tighter you could start stalling the motors. Try it in the field, see how it guides, and then see if you're satisfied. Redoing the worms takes some practice and I would not change anything until you find something functionally wrong. Chances are it was set well in the factory and will work as expected under the night's sky.
Good luck!
John
