[ INSTRUCTION MANUAL I
MODEL BHSP

This instruction manual has been written for the use of the Olympus Polarizing Micro-
scope Model

IMPORTANT
Observe the following points carefully:
Operation
1. Always handle the microscope with the care it deserves, and avoid abrupt motions.
2. Avoid exposure of the microscopetodirect sunlight, high temperature* and humidity,
dust and vibration.
If the microscope is used in an ambient temperature higher than 40°c (104"F), it
may cause a trouble to the microscope.
3. Only use the tension adjustmentringfor alteringthe tensionof the coarse adjustment.
Do not twist the two coarse adjustment knobs in the opposite directions simultane-
ously, which might cause damage.
4. Ascertain that the line voltage selector switch on the base plate is set to conform with
the local mains voltage.
Maintenance
1. Lenses must always be kept clean. Fine dust on lens surfaces should be blown or
wiped off by means of an air blower or aclean brush. Carefullywipe'off oil or finger-
prints deposited on the lens surfaces with gause moistened with a small amount of
xylene, alcohol or ether.
2. Do not use organic solutions to wipe the surfaces of various components. Plastic
parts, especially, should be cleaned with a neutral detergent.
3. Never disassemble the microscope for repair. Only authorized Olympus service per-
sonnel should make repairs.
4. The microscope should be stored in its container immediately after use. If this is not
possible, it should be covered with'a vinyl dust cover.

Explanations in detail
@ Mounting the halogen bulb
1) Releasing the bulb clamping levers @ of
the collector lens
a in the direction of
the arrow, insert two contact pins of the
halogen bulb into the socket
@. (Fig. 1)
(Recommended to use a glove or gauze
to handle the halogen bulb.)
2) Secure the bulb in position with the two
levers.
* Before use, wipe off any fingerprints or
stains on the bulb.
0 Mounting the stage
1) Prior to mounting the stage, rack down
the stage mounting dovetail
a all the
way. (Fig.
2)
2) Loosen the stage clamping screw @ by
rotating counterclockwise with Allen
wrench provided. (Fig.

Insert the stage into the mounting dove-
tail
a from above slowly. (Fig. 2)
3) Lower the stage until it comes incontact

*Do not replace filters for about a few minutes after use, in order to give time to cool.
**The circuit breaker protrudes its central part to cut off the electrical power in case of the
dimmer circuit trouble (due to short circuit, etc.) or overcurrent. To restorethe breaker, press
the central part. If the breaker is actuated again, disconnect the line cord from the
