I have in front of me a Nikon Labophot. Its stage slowly creeps

response to the stage creep. Is there an user adjustment that I can
make to correct this problem? Also what causes the focus assembly to
do this...obviously it did not do this before.
I would like to find a copy of the user and accessory documents that
apply to this instrument....can you point me to where one might find
it?
Thanks for whatever help you can offer.
You shouldn't have to do a thing. Just reach over to the right hand
side coarse focus then move slightly back. There is friction ring
there that has to be set properly, the right tension will stop the
downward creep. A bit to much makes the mechanism feel tight.

Kevin...I do not see the friction ring you mention.
Could you be more specific or perhaps a link to a picture?
Again this is a Labophot...not a Labophot2.
I do note that when the fine focus knobs were removed that NO
compression washer was present.
Thanks
