IMPORTANT
Observe the followingpointscarefully:
OPERATION
I. Always handle the microscope with the care it deserves, and avoid
abrupt motions.
2. Avoid exposure of the microscope to direct sunlight, high tempera-
turn* and humidity, dust and vibration.
*If the microswpe is used in ambient temperature higher than 4O0C
(104T), the heat may cause difficultiesin the instrument.
3. Use the tansion adjustment ring only lor altering the tensinn of the
coarse adjustment. Do not twistthe twocoarse adlustment knobs in the
opposite directions simultanmusly, which might cause damage.
4. Ascertain that the line voltage 88Iector switch on the base plate is set
to conform with thelocal mains voltage.
MAINTENANCE
1, Lenses must always be keptclean. Fine dust on lens surfaces should be
blown or wiped off by means of an air blower or a dean brush. Carefully
wipe off oil or fingerprints deposited on the lens surfaces with gauze
moistenedwith
a smallamount of xylene, alcohol or ether.

2. Do not use organic solutions to wipe the surfaces of various components.
I
Plastic parts, especialiy, shouid be cleaned with a neutral detergent.
<
3. Hew disassemble the microscope for repair. Only authorized Olyrn-
pus service petinel should make repairs.
4. The microscope should be stored in its container immediately after
-
use. If this isnot possible, it should be coveredwith a vinyldust cover. It is
best to
keep objectives and eyepieces in a desiccator, containing
desicmmts.

1. MOUNTtMGTHE HALOGEN BULB
r~
1
Gently insert the two fineprongs of the halogenbulb into thesmall holes
of the lamp holder. Avoid fingerprints on the bulb. Wipe the bulb, if
necessary.
2. AllACHING THE LAMP HOLDER (Fig. 1)
-
FI~ the lower prongs of the lamp holder and the heavier side prongs of
the lamp holder into the openings at the lower back of the base of the
microscope.
3. MOUNTING THE STAGE {Fig. 2)
1) Rack down the stage dwetail El,
2) Fit the stage carefully onto the dovetail. The Olympus nameplate
should face the user. The two stage centering screws should be
angledtoward each other; one to theleft of center,theotherto the right
of center,
3) Tghtenthe stage fastening screw @I. This screw will be found on the
user$ left at a right angle to the body of the microscope.

4. MOUNTING THE CONDENSER
Loosen the condenser clamping screw. Slidethe condenser in, aperture
scale facing forward. Tighten the clamping screw.
5. MOUNTING THE REVOLVING NOSEPIECE
1) Loosen the nosepiece clamping screw Dl (Rg. 3)
Fig. 4
2) Aligning the nosepiece dovetail slide El to themounting block, push
in the nosepiece slowly all the way.
Do not tilt or lock the nosepiecewhile inserting into themounting
block.
6. MOUNTING THE INTERMEDIATEPOLARIZING ATTACHMENT (Fig. 4)
1) Loosen the clamping screw El fully. Pull spring-loadedclamping
screw m. This will cause thelocatingpin El towithdraw. (Fig. 4) Ifthe
pin does not, loosen the s~rew further until the pinwithdraws.
2) Wfih ;lamping screw El pulled out, insert the circular dovetail of the
inlsrmediateattachment into the ring dwetait.
3) Tghten the clamping screw.
