There is absolutely no reason to either raise or lower the stage.
This is particularly true of a junk microscope like a Swift. Believe
me, raising of lowering the stage neither helps any microscope or any
user and has nothing to do with the lubrication.

Look, with Swift microscopes you should be thrilled every time a user
sees anything. They aren't made by Swift, they may have the same
model number but be made by different makers and their is no reason
but price for every design.

Now you are doing the right thing by asking, your doing a good thing
but your spending to much time on the trivial. Spend more time on
cleaning the front of the 40X and finding gurus to keep the things
running.

Thanks Gentlemen!
I would love to, but this trivia has become an object of obsession for
my colleagues.
This is about what we tell the students to do and why.
I wish I could find more documented evidence online and otherwise to
have it for "safety".
And Swift is not the highest quality mics, I realize that. But that's
all we have at the school.
Do you know of something published or posted online?

Either my book or the Nikon (www.nikonusa.com) or Olympus web site
(www.olympusamerica.com).

(sigh) wish you could get some better 'scopes!

I agree with Kevin, I've been servicing and repairing microscopes for
28 years. After servicing, the student microscopes are checked and set
up correctly, I leave the nosepiece at the 10X position and place back
in the cupboard.
There is no reason to lower or raise the stage. Access for cleaning is
quite adequate at the working position.
If I leave the stage at the last focus position before I put the
microscope away, the next user will see an image almost immediately
they put their slide on the stage. This helps to prevent the
inexperienced user crashing the objective lens through the slide
/condenser whilst searching. Why make life difficult for the student?
Spend your time explaining the correct use and operation of the
microscope to the students.

Dave, Kevin,

I think you can make a case for many scopes not being stored with any
setting on the end of travel. There is lot of aluminum in a scope and
heat cycling can put stress on things bound up tight. If some one want
to make it holy crusade I generally make them prove why and try very
hard to find why not.

There are few things in this world that rules always apply to. If a
gear rest on a stop as they do in some cheap scopes a jar can break
teeth of the gear or pinion.

All the best,
Gordon

Thanks everybody on the forum! I sure appreciate the input.
Well (sigh), again, this conversation wouldn't take place if it were
not for the lab manuals and the faculty members arguing about it.
Depending on the decision they make on the subject, I will definitely
report to everybody on this forum if the microscope breaks when the
stage is in down position or what happens to the lenses and such when
the stage is up.
Thanks again for the input!
sincerely, aleco
