If I recall there is a gear in the 1200's gear train that has a set screw

on it that can come loose...anyone have any hints as to the way to check

this and repair if needed...we are not talking about gear mesh adjustments

but I remember hearing about this some time ag and some folks on this list

checked this without too much trouble. More concerned with Dec...



this is a set screw that will come loose in transit sometimes..





thanks,

You can access the gear train in both axes by simply removing the cover on

the motor box. It is a simple matter of removing the large gear to uncover

the final gear that is attached to the worm itself. You can then check to see

if this gear is tight on the worm shaft. If not, a simply tighten the screw

with an Allen wrench. Make sure the screw is lined up with the flat an the

shaft before tightening. It is a rather uncommon occurance, by the way, for

this screw to be loose. It would in any case not come loose in transit.
