it off with a camel hair brush before attempting to wipe the surface
clean.
Optical surfaces should be cleaned with a lint-free cloth, lens tissue
or a cotton swab moistened with methanol or commercially available
glass cleaner. It is very important to avoid the excessive use of sol-
vent.
The cloth lens tissue or cotton swab should be moistened with sol-
vent, but not be wet enough for the solvent to seep around the lens.
No part of the microscope is quite so vulnerable to dirt, dust and oil
as the front lens of the objective. Whenever lack of contrast, clou-
diness or poor definition is encountered, carefully check the conditi-
on of the front lens with a magnifier.
The lower magnification objectives have fairly large front lenses and
can be cleaned with a cloth or lens tissue wrapped around a finger
and moistened with methanol. The 40x and 100x objectives require a
little more care and examination with a magnifier. To achieve the high
degree of flatness obtained with the higher magnification objectives,
it is necessary to use a small concave front lens of fairly short radius
or curvature. The surface of this front lens can be readily cleaned with
a toothpick covered with a cotton tip, or with a small cotton swab.
Moisten the cotton with methanol and squeeze it almost dry. Wipe the
front lens lightly without applying undue force or scrubbing action.
Make sure that the cotton tip contacts the concave lens surface. Check
the objective with a magnifier after cleaning.
Should you need to remove the viewing body, be careful not to acci-
dentally touch the outer lens surface on the underside of the body.
Finger prints on this surface will reduce image clarity. This lens can
be cleaned in the same manner as objectives and eyepieces.

5.2 Mechanical Maintenance

Using the dust cover is the most important factor in keeping the micros-
cope in good mechanical and physical condition.
The Leica CM E has a durable finish. All non-optical parts of the instru-
ment can be cleaned with methanol, naptha or soap and water. Avoid
the use of all other organic solvents when cleaning the instrument.

5.3 Lamp Replacement

CAUTION: Unplug the instrument before attempting to change
the lamp.
CAUTION: The glass envelope of the lamp may be extremely
hot. Do not attempt to change the lamp before it is completely
cooled or without wearing adequate skin protection. The glass
should not be handled with
ched with bare hands clean the surface with a lens tissue and
methanol prior to installation.
The only component in the Leica CM E that may require periodic
replacement is the illuminator lamp.

A. Before replacement, unplug the instrument.
B. Open the lamp door by pulling the locking pin
C. After it has cooled, carefully hold the lamp using a lens cloth
and remove it from its socket.
D. Place the new lamp into the socket using a lens cloth.
E. Close the lamp door, being sure to push the locking pin in
until it stops.
F. Never operate the microscope illuminator unless the lamp
door is securely closed.
5.4 Electrical Considerations / Equipment Ratings
CAUTION: Risk of electric shock. Removal of the bottom cover
of the microscope exposes hazardous voltages, which if contac-
ted, could cause injury or death. Please refer servicing to qua-
lified personnel.
