itself; take also into account the height of each objective since the 100x objective is
longer and it could touch the sample.
g.
When using 100x objective, move the condenser to the highest position and use a
drop of immersion oil; avoid the formation of bubbles that could affect observation of
sample. The 100x objective must be wiped off after each use with a lens paper to
remove all the remains of immersion oil.
h.
When turning the coarse and fine focusing knobs to move the stage, if it is too hard or
too loosen it will be necessary to adjust the tension adjustment ring. The tension
adjustment ring is placed in the right coarse focusing knob.
i.
Move the sample on the stage by using the translation knobs to study the different
structures of the specimen.
j.
In case of using B-HB11 model with binocular head adjust the interpupillary distance
(distance between eyepieces) before starting observation. Moreover, it will be
necessary firstly to focus image with one of the eyepieces and then adjust the diopter
correction of the other eyepiece until the image is also focused with this eyepiece.

Maintenance
a.
The microscope must be installed in a dry, clean and free of acid and alkaline vapors
space; avoid the direct exposure to direct sunlight.
b.
Environmental conditions: the temperature must be between 0ºC- 40ºC and the

the lens with a soft cloth moistened with a few organic solvent (mixture of ether and
alcohol 7:3).
e.
Do not wipe the lens surface very regularly, or else the lens will be scraped, reducing
the quality of the transmission and imaging. Please keep the rest of the instrument
clean.
f.
Keep the mechanical parts clean and dry.
g.
Unplug the power cable and disconnect the microscope from the power supply in
case of not being used for a long time; adjust the light intensity to the minimum and
