Caution
Care & Maintenance
If the microscope is used in a manner not specified by this manual, the safety of the user may not be warranted.
In addition, the equipment may also suffer damage. Always use the equipment as outlined in this instruction
manual.
Your microscope has been engineered for a long and safe operational life with the least amount of maintenance
required. In general, routine maintenance is limited to keeping the microscopes working parts lubricated and optics
clean. Always cover the microscope with the provided dust cover when not in use.
1.
To clean the lens surfaces, remove dust using a soft brush or gauze (compressed air dust cans are ideal). For
removing finger marks or grease, soft cotton cloth/ lens tissue or gauze lightly moistened with cleaning solution
(85% petroleum ether and 15% isopropanol) should be used. For cleaning the objective optics, use xylene.
Observe sufficient caution in handling xylene.
Place the objectives and/or eyepieces on a dust-free surface (e.g. fresh aluminum foil). All other optical
components to be cleaned should be as accessible as possible.
a. Blow all loose dust particles away with a dust blower.
b. Remove all water-soluble dirt with distilled water. If this is unsuccessful repeat using a solution of diluted hand
soap liquid. Remove any remaining residue with a dry cotton swab.
c. To remove oil, use a solution of diluted hand-soap liquid initially. If this does not produce a satisfactory result,
repeat the cleaning using a solvent (Optical Cleaning Solution 85% petroleum ether and 15% isopropanol).
d. Grease must always be removed using a solvent.
e. Cleaning is achieved by using a spiral motion from the center to the rim. Never wipe using zig-zag movements as
this will only spread the dirt. With larger optical surfaces (e.g. tube lenses) the spiral motion starts initially at the rim
before moving to the middle and is only then followed by a center to rim cleaning motion. Normally several spiral
wipes are recommended.
We recommend pure, volatile petroleum ether or Optical Cleaning Solution as explained in point (c) above.
Wipe using a spiral movement. Do not use a zig-zag motion!
2.
Avoid the use of any organic solvent ( e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted surfaces of
the instrument. Painted surfaces can be cleaned with a very lightly moistened micro fiber cloth. Loose dust and
other dirt can be removed using a brush of soft hair used exclusively for this purpose.
