the adjustment knobs.

CAUTION

during stage travel, and the stage stopping accuracy may be

imperiled.

} After long hours of use, the stage guide may be deviated and the stage

travel range may be decreased.

However, this is not malfunction and can be corrected easily as described

below.

[Treatment]

Horizontal direction: Hold the specimen holder and move the stage guide

to the left and right so that it hits the stoppers.

Vertical direction:

Hold the upper stage and move it to the front and rear

so that it hits the stoppers.

Stage Feed Knob Rubber Caps (Optional)

} When the X- and Y-axis knobs are fitted with the rubber caps, the knobs

can be adjusted without slipping and fine adjustment is possible by

holding the knobs with a very light force. The knob rubber caps also

reduce fatigue after long hours of operation.

The U-SHGT thick type (thickness 5 mm) and U-SHG thin type (thickness

2 mm) knob rubbers are available.

To attach the knob rubbers:

First fit the larger knob rubber to the Y-axis (upper) knob from below it,

then fit the smaller knob rubber to the X-axis (lower) knob from below it.
