6. 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.19).
7. 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.)
8. Oil-immersion observation
Use only a minimum quantity of oil. If too much oil is applied, surplus oil may flow out to the stage and
the condenser which may lead to degraded performance.
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.
9. Shipping clamps
The microscope is held tightly by the clamps during shipment.
Be sure to remove the clamps before use. For details, see P.29.
