10. Maintenance and cleaning
Always place the dust cover over your MSS-200 Series microscope after use. Always keep the eyepieces mounted on
the microscope to avoid dust entering the instrument
10.1 Cleaning the optics
When the eyepiece lenses are dirty, they can be cleaned by wiping a piece of lens paper over the surface (circular
movements). If this does not help put a drop of alcohol on the lens paper and wipe it. Never put Isopropyl or alcohol
directly on the lens! Cole-Parmer has various optical cleaning wipes available
It is not necessary - and not recommended - to clean the lens surfaces at the inner side of the objectives. Sometimes
dust can be removed with high pressured air
Caution
Cleaning cloths containing plastic fibers may damage the coating of the lenses!
10.2 Maintenance of the stand
•
Dust can be removed with a brush. In case the stand or base plate is really dirty, then clean the surface with a
non-aggressive cleaning product
•
All moving parts - like the height adjustment or the coaxial coarse and fine adjustment - contain ball bearings
that are not dust sensitive. With a drop of sewing-machine oil the bearing can be lubricated
10.3 Replacing the fuse
To change the fuse, follow the procedures below:
•
Remove the power cord from the back of the microscope
•
Locate the fuse compartment, which has a fuse image. It is typically
located close to the power connector
•
Remove the fuse compartment. To do so, insert a flat head
screwdriver behind the fuse compartment and gently pry it loose
•
Insert the new fuse into the compartment, and then replace the
fuse compartment back to where it was originally
•
Power up the microscope and test
•
Fuse specification: 250 V F1A glass, 5 x 20 mm
Note:
The fuse may blow in order to prevent internal damage to the microscope and in most cases, replacing the
fuse with a correctly rated fuse will resolve the issue. However, should you encounter a blown fuse frequently, please
contact your distributor for further assistance
