1 Daily Maintenance and Periodic Inspection and Maintenance
MITSUBISHI CNC
III - 2
1.1 Maintenance Items
Maintenance is categorized into daily maintenance items (items to be carried at set intervals) and periodic maintenance
items (replacement of parts when life is reached).
Some parts will not function in a hardware manner when the life is reached, so these should be replaced before the life is
reached.
1.1.1 Escutcheon
(1) Cleaning the escutcheon
(a) Prepare the rear side of the escutcheon to clean.
(b) Wipe the escutcheon with a soft, clean, dry cloth. If cleaning is still required, put some neutral detergent on a
cloth and wipe. Do not use alcohol, thinner, etc.
1.1.2 LCD Panel
(1) Handling the LCD panel
(a) Precautions for use
-
The polarizing plate (display surface) of the LCD panel surface can be easily scratched, so be careful
during handling.
-
Glass is used in the LCD panel. Be careful not to drop the LCD panel or allow it to hit hard objects, as the
glass may chip or break.
-
The polarizing plate may be stained or discolored if drops of water, etc., adhere to it for long periods, so
be sure to wipe off any moisture immediately.
-
Wipe off any dirt, dust, etc., on the polarizing plate using absorbent cotton or other soft cloth.
-
A CMOS LSI is used in the LCD panel, so be careful of static electricity when handling.
-
Never disassemble the LCD panel. Doing so will damage the panel.
(b) Precautions for storage
-
Do not store the LCD panel in locations having a high temperature or humidity. (Store within the storage
temperature range.)
-
When storing the LCD panel as an individual unit, be sure that other objects do not touch or hit the
polarizing plate (display surface).
-
When storing the LCD panel for long periods, be sure to store in a dark place away from exposure to
direct sunlight or fluorescent light.
