Before Use BS-2082 Series
1. Operation Notice
1. As the microscope is a high precision instrument,
always operate it with care, and avoid physical shake
during the operation.
2. Do not expose the microscope in the sun directly,
either not in the high temperature, damp, dust or
acute shake. Make sure the worktable is flat and
horizontal. Following environment is required when
operating: Indoor temperature: 5℃～40℃, Max
relative humidity: 80%.
3. When moving the microscope, use both hands to
hold its back hand-clasping ① and the front base ②,
and lay it down carefully (see Fig. left).
★It will damage the microscope by holding the
stage, focusing knob, head or light source when
moving.
4. When working, the surface of light source will be
very hot. Make sure there is enough room for the
heat dissipating around the light source.
5. Connect the microscope to the ground to avoid
lightning strike.
6. For safety, make sure the power switch is at “O”
(off) and power it off before replacing the bulb or
fuse (see Fig. left).
7. Wide voltage range is supported as 100~240V.
Additional transformer is not necessary. Make sure
the voltage is in this range.
8. Use the special wire supplied by our company.
2. Maintenance
1. Wipe the lens gently with a soft tissue. Carefully wipe off the oil marks and fingerprints on the
lens surfaces with a tissue moistened with a small amount of 3:7 mixture of alcohol and ether or
dimethylbenzene.
★As the alcohol and ether is flammable, don’t place these chemical near to fire or fire source.
For example, when turning on or turning off the electrical device, please use these chemical in
a ventilated place.
2. Don’t use organic solution to wipe the surfaces of the other components. Please use the
neutral detergent if necessary.
3. If the microscope is damped by liquid, please power it off immediately and wipe it dry.
4. Never disassemble the microscope, otherwise the performance will be affected or the
instrument will be damaged.
5. After using, cover the microscope with a dust cover.
3. Safety Sign

Signification
The surface gets hot and don’t touch it with bare hand.
Study the instructions before use. Unsuitable operation would lead to
person hurt or instrument faulty.

2-2 Assembling Steps
2-2-1 Assemble and Replace the Halogen Bulb
(1) Loose lock-screw ① completely by M4 spanner,
then take off the cover group. (See Fig. 1)
(2) Open the bulb lock piece②, and take the bulb③
with clean glove or soft tissue, insert the bulb pins④
into the jack on the bulb holder⑤, the bulb should be
vertical after assembly. (See Fig. 2)
(3) Loose the bulb lock piece②, lock the bulb and
install the cover group.
★Don’t touch the bulb with fingers. If there is a
fingerprint left on the bulb, please wipe it with
clean soft cloth.
★Bulb selected only: 12V/100W Halogen bulb (Philips
7724).
★Before replacing the bulb, make sure to cut off the
main power and wait for both the bulb base and
bulb cooling down.
2-2-2 Assemble the Light Source Group
Push the light source holder① into the body holder,
Make the light source group to be horizontal with the
body group and lock the screw②. (See Fig. 3)
2-2-3 Assemble the Stage
(1) Loosen the lock-screw① on the stage. (See Fig. 4)
(2) From a rear area of the rounded hole center on the
base, carefully ring the two “V” buttons on the bottom
of the stage into the “V” rounded groove②, then
screw down the lock screw①.
