Safety concept
The individual modules of the Leica DM microscopy series include an interactive CD-ROM with
all relevant user manuals several languages.
Keep it in a safe place, and readily accessible
to the user. User manuals and updates are also
available for you to download and print from
our web site at
www.leica-microsystems.com.
This operating manual describes the special
functions of the individual modules of the Leica
DM microscopy series and contains important
instructions for their operational safety, maintenance, and accessories.
You can combine individual system articles with
articles from external suppliers. Please read the
user manual and the safety requirements of the
supplier.
Before installing, operating or using the instruments, read the user manuals listed above. In
particular, please observe all safety instructions.
To maintain the unit in its original condition
and to ensure safe operation, the user must
follow the instructions and warnings contained
in these user manuals.

Instructions on use
Intended use
The Leica DM 500 microscope is an optical
instrument which uses magnification and illumination to improve the visibility of objects. It
is used for observing and documenting.
The Leica DM 500 microscope may be used only
in closed rooms and must be placed on a solid
floor.
The Leica DM 500 microscope can be used in
clean rooms without any problems.
• Position the Leica DM 500 microscope
so that it can be disconnected from the
power supply at any time. The power cord must
remain accessible at all times.
Leica DM 500
Place of use
Only use the instruments in closed, dust free
rooms and between +10 °C and +40 °C. Protect
the devices from oil, chemicals and extreme
humidity. If using the devices outdoors, protect
them from dust and moisture. Never use electrical devices outdoors. Install electrical devices at
least 10 cm from the wall and away from flammable substances.
Avoid large temperature fluctuations, direct
sunlight and vibrations. These conditions
can distort measurements and micrographic
images.
In warm and warm-damp climatic zones,
the individual components require
special care in order to prevent the build-up of
fungus.

Health risks and dangers of use
Health risks
Workplaces with microscopes facilitate
and improve the viewing task, but they
also impose high demands on the eyes and
holding muscles of the user. Depending on the
duration of uninterrupted work, asthenopia
and musculoskeletal problems may occur. For
this reason, appropriate measures for reduction
of the workload must be taken:
The ergonomic design and construction of the
Leica microscopy series are intended to reduce
the exertion of the user to a minimum.
Dangers during use
ϘϘ The Leica DM 500 microscope may only be
connected to a grounded socket.

1. Find the field of view on the slide that you
would like to inspect.
3. Place a drop of Leica Immersion Oil on the
specimen slide on the area of the specimen
that you were inspecting.
5. Raise the stage slowly using the coarse
focus knob until the drop of oil on the specimen slide just comes in contact with the
front of the oil immersion objective lens.
2. Lower the stage to its lowest position using
the coarse focus knob.
4. Swing the oil immersion objective in place

General maintenance
General
Always carry the microscope using two
hands. There is a handle on the back of
the microscope and an undercut in the front for
this purpose.
ϘϘ
• Leica DM 500
The cord wrap allows you to wrap the cord
in such a way that only the length you need
is extended.
ϘϘ
Keep all optical components clean. Cleanliness is important for maintaining good
optical performance.
ϘϘ
The microscope should always be covered
with the plastic dust cover (provided with
the instrument) when it is not in use.
Manual
ϘϘ
If any optical surface becomes coated with
dust or dirt, clean the surface by blowing it
off with a syringe or brushing it off with a
camel hair brush before attempting to wipe
the surface clean.
ϘϘ
Optical surfaces should be cleaned with a
lint-free cloth, lens tissue or a cotton swab
moistened with methanol or a commercially available glass cleaner. Do not use
alcohol.
ϘϘ
It is very important to avoid the excessive
use of solvents, so use them sparingly. The
lint-free cloth, lens tissue or cotton swab
should be moistened with solvent, but
not be wet enough for the solvent to seep
around the lens.
37
General maintenance (cont.)
ϘϘ
No part of the microscope is quite so vulnerable to collecting dirt, dust, and oil as the
front lens of the objective. Whenever you
encounter lack of contrast, cloudiness or
poor definition, carefully check the condition of the front lens with a magnifier.
ϘϘ
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.
ϘϘ
Cleaning 40× and 100× objectives requires
more care. Note: To achieve the high degree
of flatness obtained with higher magnification objectives, the objective has 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 (do not use alcohol). Wipe the front lens lightly without
applying undue force or scrubbing action.
Leica DM 500
Make sure that the cotton tip contacts the
concave lens surface. Check the objective
with a magnifier after cleaning.
ϘϘ
If you need to remove the microscope’s
viewing body, be careful not to accidentally
touch the outer lens surface (located on
the underside of the body). Fingerprints on
this surface will reduce image clarity. This
lens can be cleaned in the same manner as
objectives and eyepieces.
Illumination
ϘϘ The Leica DM 500 uses LED illumination.
Therefore, no lamp changing is required for
the life of the microscope.
