INSPECTION AND MAINTENANCE
Inspection
While basic units and other units have been used for a long period of time,
the connector connection area may become loose, the battery may wear out,
or another nonconformity may occur in operation.
To avoid any nonconformities, inspect the basic units, other units, and the
wiring periodically. The major inspection items are as follows.
• Check to ensure that the connector is not disconnected or loose.
• Check to ensure that terminals on terminal plates are not loose.
• Check to ensure that the wiring cables among units and each equipment
are not damaged.
Maintenance
While basic units and other units have been used for a long period of time,
dirt will adhered. Wipe off any collected dirt with a clean, dry cloth.
Wipe off any dust and dirt that has collected on small and narrow portions
with cotton swabs.
Be sure to turn off the power before starting any inspection or maintenance.
