USERNOTICE BS-5092
Ⅰ.Safety Precautions
1. Carefully open the box, avoid the accessories, like lens, dropping to ground and being
damaged.
2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and
easy shaking environment. Make sure the stage is smooth, horizontal and firm enough.
3. When moving the instrument, please use two hands to grip with the two sides of the
microscope body.
4. When running, the lamp house and nearby parts will be very hot. Please ensure there is
enough cooling room for them.
5. Make sure the instrument is earthed, to avoid lighting strike.
6. For safety, be sure the main switch is in “O”(off) state before replace the halogen lamp or
the fuse, then cut off the power, and do the operation after the lamp bulb and the lamp
house completely cool (designated bulb:. 24V/100W halogen lamp)
7. Use the factory supplied power cord, please.
8. II. Maintenance
1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them
yourself.
2. The nosepiece and coarse/fine focus unit have a compact and precise frame, so please
don’t disassemble them as possible as you can.
3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating
the optical elements especially.
4. The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece
of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or xylene.
(Note that the alcohol and the xylene are all burned easily, do not let them near the fire,
and use them in a drafty room as possible as you can.)
5. Don’t use organic solvent to wipe the non-optical elements, when you need to clean,
use the soft detergent, please.
6. When using, if the microscope is splash by liquid, cut off the power at once, and wipe
up the moisture.
7. Do not disassemble any parts of the microscope. That will affect the function or decline

the performance of the microscope.
8. Place the instrument in a cool, dry position. After using the microscope, remember to
cover it with dust helmet. Do wait for the lamp house cooling completely before cover.

2-1 Assembly Diagram
The diagram below shows how to assemble the various components. The numbers indicate
the order of assembly.
When assembling the components, make sure that all parts are free of dust and dirt,
and avoid scratching any parts or touching glass surfaces.
Keeping the hexagon- spanner well, when change the spare parts, you will use it.

2-2DetailedAssemblyProcedure BS-5092
2-2-1 Installing the Polarizing Stage
Support Device
1. Before installing the device, be sure to
adjust the coarse focus knob①. Make
the guide board②(see figure 1) down
to the lowest position, so you can
install the mechanical stage support
device easily.
2. Hold on the mechanical stage support
device (figure 2), place it from the top
of the guide board (figure 1), and let
the device (figure2) falling free until it
reach the limit position. Use the
hexagon wrench screw down the
locking block ③to make the stage
support device and the guide board
fixed together.
2-2-2Mouting Revolving Round
Stage
1. Loosen the centering knobs④。
2. Position the stage with the venire scale
⑤in front, and carefully lower the stage
onto the round dovetail on the stage
bracket⑥with the positioning pin on
the stage aligned with the groove on the
front of the stage bracket, then loosely
tighten the centering knobs④. Turn the
stage to check it is mounted properly,
finally tighten the centering knob.
Mounting Stage Clips
Insert the stage clips securely into any two
holes⑦on the stage top surface.
Mounting Polarizing Ruler
Insert the positioning pins on the underside
of the ruler into the positioning holes⑧on
the stage surface, using the Allen
screwdriver provided with the microscope

2-2-3 Installing the Objective
1. Adjusting the coarse focus knob until the support
device of the mechanical stage reach its low limit
position.
2. Insert the 10X objective into the primary hole
(which without centering holes on its sides) on the
nosepiece, then push the nosepiece clockwise and
install other objectives by the sequence of low to
high magnification ( figure 5).
Installing objective in this way will make the
change of magnification to be easier while in
using.
Clean the objective regularly as it is very
sensitive to dust.
When operating, use 10 ×magnification
objective to search specimen and focus firstly,
then replace with higher magnification
objective if necessary.
When replacing the objective, slowly turning
the nosepiece until you hear “clicked”, that
means the objective enter the required
position--the light path center.
2-2-4Mounting reflected illumination system
(Fig.6)
1. Mount the Illumination System①into the round
dovetail on the head of the microscope body
properly and use the Allen screw driver to tighten
the set screw②to fix it.
2-2-5 Mounting Bertrand lens unit (Fig.6)
1. Mount the Bertrand lens unit③into the round
dovetail on the reflection Illumination System①t
properly and use the Allen screw driver to tighten
the set screw④to fix it.
2-2-6 Mounting trinocular viewing head (Fig.7)
1. Mount the trinocular viewing head⑤onto the
illumination system properly and use the Allen
screw driver to tighten the bolt⑥）to fix it.

2-2-7 Installing the Video Port (Fig.7)
Insert the video port ⑦into the trinocular viewing head, then screw down the bolt⑧to fix it.
2-2-8 Installing the Eyepiece (Fig.7)
Insert the eyepiece into the eyepiece tube until they are against each other.
2-2-9 Installing the lamp house
1. Push the lamp house into the illumination kits (Fig. 8)
gently until they are against each other, turn to a proper
position and then screw down the bolt①to fix it.
2. Insert the power plug②into the power jack of the
microscope③/④, and screw down the bolt to fix it.
For transmitted light illumination, the power jack③is
used. For reflected light illumination, the power jack④is
used.
2-2-10 Mounting Polarizer and Analyzer
1. Insert the polarizer⑤into its slot with the silkscreen
surface toward the front and make it in the light path
center.
2. push the analyzer⑥into its slot.
NOTE: the polarizer and analyzer are engaged when
pushed in to the second click-stop position. To
disengaged the polarizer and analyzer, and to place the
empty hole in the light path, pull the analyzer out to the
first click-stop.
2-2-11 Mounting Test Plate Compensator
1. Insert the optical compensator⑦into the test plate
adapter, and securely tighten the clamping knob⑧,as
shown in fig.9.
