User Notices BS-6022RF/TRF
I. Safety note
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 sidesofthe
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. Always ensure that the grounding terminal of the microscope and that of the wall outlet are
properly connected. If the proper power cord is not used, product safety performance cannot be
warranted.
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.(Specified Lamp: G6.35 24V100W halogen lamp)
7. Use the factory supplied power cord, please.
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, 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 needtoclean,usethe
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

2-1 Installation Diagram
The following figure shows the installation sequence of the components take BS-6022TRF for
example. The number in the figure show the installation steps.
Before installing, be sure every components is clean, do not score any parts or glass surface.
Keep well with the supplied hexagon wrench. When changing the components, you will need
it again.

2-2 Installation Steps BS-6022RF/TRF
2-2-1 Installing the Mechanical Stage
Support Device
1. Before installing the device, be sure to adjust
the coarse focus knob ①.Maketheguide
board ②down to the lowest position, so you
can install the mechanical stage support
device easily.
2. Hold on the mechanical stage support device
(Fig. 2), place it from the top of the guide
board (Fig.1), let the device (Fig.2) falling
free until it reach the limit bolt. Use the
hexagon wrench screw down the locking
block③, make the stage support device and
the guide board fixed together(Fig.3).
Fig.1, Fig.2 show the installation sequence
of the components which take
BS-6022TRF for example. For
BS-6022RF, there are two limit bolt
holes with different height on the guide
board ②to meet with sample which
have different thickness: the upside hole
is for sample with 0 ～30mm thickness,
the underside hole is for sample with
20～50mm thickness.
The mechanical stage ⑤have been
adjusted horizontally and fixed together
before leaving factory. Do not
disassembly unless necessary, that may
affect the observation precision of the
instrument.

2-2-2 Installing the reflected light
brightfield/darkfield illuminator
1. Installing the reflected light illuminator
(Fig.4) on the head of
microscope body(Fig. 5), and turn to a
proper position, then screw down the bolt
⑥to fix it.
2-2-3 Installing the Video Port
1. Insert the video port (Fig.6) into the
illuminator (Fig. 4), then screw down
the bolt to fix it.
2-2-4 Installing the Objective
1. Adjusting the coarse focus knob until the
support device of the mechanical stage
reach its low limit position.
2. Wresting the lowest magnification
objective onto the nosepiece from the
left or the right side, then push the
nosepiece clockwise, then place other
objectives by the sequence of low to
high magnification (Fig.7).
Installing objective this way will make
the change of magnification to be easier
while in using.
Clean the objective regularly, the
objective of the inversed microscope
is very sensitive to dust.
When replacing the objective, slowly
turning the nosepiece until you hear
“clicked”, that means the objective
enter the required position--the light
path center.

2-2-5 Installing the Video Port (optional)
Insert the video port (Fig. 8) into the trinocular
unit (Fig. 6), then screw down the bolt ⑨to
fix it.
2-2-6 Installing the Eyepiece
Insert the eyepiece (Fig.9) into the eyepiece
tube until they are against each other.
2-2-7 Installing the Lamp Housing
1. Pushing the lamp holder (Fig.10)into the
illumination kits(Fig. 4) gently until they are
against each other, turn to a proper position, then
screw down the bolt ⑧to fix it.
2. Insert the power plug①into the power jack of
the microscope②, and screw down the bolt to fix
it. The result in show in Fig. 12.
◎When using transmitted light illuminator,
remove the dust cap first, then pushing the lamp
holder (Fig.10)into the jack on the back of the
microscope (Fig.11) gently and turn to a proper
