It is not necessary – and not recommended – to clean the lens surfaces at the inside of the objectives. Sometimes dust
can be removed with high pressured air. There will never be dust in the objectives if the objectives are not removed
from the revolving nosepiece
Caution
Cleaning cloths containing plastic fibers may damage the coating of the lenses!
Maintenance of the stand
Dust can be removed with a brush. In case the stand or table is really dirty you can clean the surface with a non-
aggressive cleaning agent. All moving parts -like the height adjustment or the coaxial course and fine adjustment- -
contain ball bearings that are not dust sensitive. With a drop of sewing-machine oil you can lubricate the bearing.
Changing the batteries
Caution:
Always remove the power cable from the mains supply!
•
Remove the small lid out of the bottom cover of the microscope
•
Place the batteries and put the lid back into place
Replacing the fuse
To change the fuse, please follow these procedures:
•
Remove the power cord from the back of the microscope
•
Locate the fuse compartment, which has a fuse image. It is typically located beneath the
power connector
•
Remove the fuse compartment. To do so, insert a flat head screwdriver between the metal
power tines and gently pry the fuse compartment loose with a slight downward and
outward motion
•
Insert the new fuse into the compartment, and replace the fuse compartment
•
Power up the microscope and test
•
Fuse specification: 250 V F1A, glass 5 x 20 mm
Note:
The fuse may blow. In most cases, replacing the fuse with the correct type and rating will
resolve the issue. However, should you encounter a blown fuse frequently, please contact your
distributor for further assistance.
