You should find a small hex bolt or screw thread on the right hand side at the bottom of the head. Photographs would be helpful

Swift microscopes, as far as i know, don't readily come with a users manual like one would find for a standard home device. Nine fifties are of the simplest microscopes around, any guide to microscopy will do as a user's manual. As for repairs, anyone that is mechanically inclined and with the right tools (allen hex keys, screwdrivers, pliers, lubricant) will be able to fix one after a few minutes of tinkering with it. Don't panic.

Unfortunately, if you indeed have water or oil inside the lens it is probably ruined. Obviously the seals have deteriorated away. Objectives are practically irreparable. They cannot be disassembled. Very reasonable new and used Replacements are available at: Delta Optical Instruments, Inc. Inquire at: robin@deltaoi.com

Classroom scopes get dirty very fast. This can cause the images to look dim and faded. Contact a Microscope Service Company. If you are in the Arkansas area that would be: Delta Optical Instruments, Inc. Email: robin@deltaoi.com

the objective is dirty with oil. Clean this off and it should solve the problem. The oil if it has been there for a long time may dry and become hard to remove.

I seem unable to get a user or service manual online, however at a guess I would think that the retaining mechanism is inside the "head" of this beastie, so in order to access you would need to undo the screw that retains the viewing piece, this should give you access to the internals, however you have to be vary carefull that you do not contaminate the microscope. it may be easier to send it to be "cleaned" and hopefully when it returns it will have been tightened up.

Go on line to the Manufacturer's web site and request an owner's manuel for your microscope!

A good idea would be to check the wiring by taking it apart. if the wires are bad, you must get new ones and solder them to the light socket and the battery holder making sure not to cross the positive and negative wires.
