（4）Refocusing
When changing specimens using the refocusing
mechanism, gently lower the stage by hand taking
care not to hit the field lens with the condenser holder
(p. 15).
（5）Focus Knobs
Do not turn the right and left focus knobs
simultaneously in opposite directions. Do not turn the
coarse focus knob any further after the stage has
been moved up or down to its limit. These operations
will damage the focusing mechanism.
(The coarse focus knob has a protection device. The
knob turns freely for a while after it has reached its
upper limit.)
（6）Oil-Immersion Observation
Use only a minimum quantity of oil. If too much oil is applied, surplus oil could flow out to the
stage and the condenser which could lead to degraded performance.
WARNING
When using petroleum benzine or absolute alcohol to wipe off immersion oil or
to clean the lenses, follow the instructions provided by their manufacturers.
Absolute alcohol and petroleum benzine are inflammable. Take great care when
handling them.
（7）Shipping Clamps
The microscope is held tightly by the clamps
during shipment. Be sure to remove the
clamps before use. For details, see p. 35.
