4. Maintenance
WARNING:
Do not perform maintenance or repair(s) on the Tool Changer or modules unless
the Tool is safely supported or placed in the tool stand, all energized circuits (e.g. electrical,
air, water, etc.) are turned off, pressurized connections are purged and power is discharged
from circuits in accordance with the customer specific safety practices and policies. Injury
or equipment damage can occur with the Tool not placed and energized circuits on. Place
the Tool in the tool stand, turn off and discharge all energized circuits, purge all pressurized
connections, and verify all circuits are de-energized before performing maintenance or
repair(s) on the Tool Changer or modules.
NOTICE:
The cleanliness of the work environment strongly influences the trouble free operation of
the Tool Changer. The dirtier the environment, the greater the need for protection against debris.
Protection of the entire EOAT, the Master, the Tool and all of the modules may be necessary. Protective
measures include the following:
Placement of the tool stands away from the debris generators.
•
Covers incorporated into the tool stands.
•
Guards, deflectors, air curtains, and similar devices built into the EOAT and the tool stand.
