Specimen stub assembly
Ball wrench 2
Stage feeding screw
Figure 4.2.3-6 Hexagon Socket
NOTE : Specimen stub assembly can be fixed with the hexagon socket head screw
outside of the holder base. The vibration trouble might occur when observing at
high magnification or observing the heavy specimen. Therefore, tighten the
hexagon socket head screw with the provided ball wrench 2 to fix the specimen
holder. In that case, use the ball wrench 2 so that it does not touch the stage
feeding screw. When removing the specimen stub assembly, loosen the hexagon
socket head screw first, and remove it. Do not use the ball wrench other than the
provided ball wrench 2.
NOTICE : When bringing you hand close to the motion mechanism of the specimen stage
during specimen change, use caution not to touch any moving parts, such as
gears and driving screws, and not to get your clothing caught.
