Cautions on Handling the Immersion Oil
•
Close the container cap tightly after use. Make sure that the cap is closed tight after
refilling the container. Check the cap periodically to make sure it has not come loose,
allowing oil to leak out.
•
Do not press the container hard. Oil could splash out.
•
If you find an oil drips around the container, wipe them off.
•
Avoid contact of immersion oil with eyes or skin. In the event of contact with eyes or skin,
take one of the following measures although Nikon immersion oil does not contain any
toxic ingredients.
◊
Contact with skin:
Rinse your skin thoroughly with soap and water.
◊
Contact with eye:
Rinse your eye thoroughly with water (more than 15
minutes) and see a doctor.
•
Do not leave immersion oil in the sun (ultraviolet rays can damage it).

Adjusting the Torque of the Coarse Focus Knob
The tension (torque) of the coarse focus knob
rotation can be adjusted. To increase the tension,
turn the coarse focus knob torque adjustment ring
counterclockwise. The torque adjustment ring is
located at the back of the coarse focus knob. To
decrease the tension, turn the ring clockwise. Do
not decrease the tension too much. If it is too
loose, the stage will fall under its own weight.
