Question about EQ-6 lock lever

Hi

Can someone help me with this problem (or maybe not a problem).
I used to observe with my LX200 12" (fork mount) and never have balanced the
scope, but never found problems, maybe some tracking faults.

I recently bought a EQ-6 mount for my Taka FC-100 and found a problem with
the RA lock lever. Maybe it is normal, I don't know, I have never used a GEM
before.

The problem I found is about the lock lever pressure necessary for the
clutch to work. When I press the RA lock lever a little bit harder to
"really" lock, the RA axis seems to stop moving. But when I balance the
system and press the lever "half way" the RA axis moves without problems,
and if I loose a bit less then "half way" it seems to "slide" in certain
positions of the axis.

What I want to know is:
1) To use a GEM balancing is a must ?
2) Does the lock lever clutch system of my EQ-6 needs some "tunning" ?

Thanks for any help.

Carlos
