5. 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 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 tool stands away from debris generators.
•
Covers incorporated into the tool stands.
•
Guards, deflectors, air curtains, and similar devices built into the EOAT and the tool stand.
5.1 Preventive Maintenance
The Tool Changer and optional modules are designed to provide a long life with regular maintenance. A
visual inspection and preventive maintenance schedule is provided in the following table depending upon
the application. Detailed assembly drawings are provided in

Checklist
Mounting Fasteners
г
Inspect fasteners for proper torque, interferences, and wear. Tighten and correct as required. Refer to
Ball Bearings/Alignment Pins/Bushings/Bearing Race
г
Inspect for wear and lubrication. MobilGrease XHP222 Special a NLGI #2 lithium complex grease with molybdenum
disulfide additive is suggested for locking mechanism and alignment pin lubrication. Over time, lubricants can become
contaminated with debris. Therefore, it is recommended to thoroughly clean the existing grease and replace with new
as needed. See
Section 5.2—Cleaning and Lubrication of the Locking Mechanism and Alignment Pins
.
г
Inspect for excessive alignment pin/bushing wear, may be an indication of poor robot position during pickup/drop-off.
Adjust robot position as needed. Check tool stand for wear and alignment problems. To replace worn alignment pins,
refer to
Section 6.2.4—Alignment Pin Replacement.
г
Inspect for wear on the ball bearings/bearing race, may be an indication of excessive loading.
Sensors and Cables
г
Inspect sensor cable connectors for tightness, if loose tighten connections.
г
Inspect sensor cables for any damage, cuts, and abrasion. Replace as necessary.
Hoses
г
Inspect hose connection for tightness and leaks. If leaking or loose secure hose connection.
г
Inspect hoses for interferences, abrasions, cuts, and leaks. Replace as required.
Electrical Contacts/Pin Block (Modules)
г
Inspect for damage, debris, and stuck/burnt pins. Clean pin blocks as required, refer to
Electrical Module Pin Block Inspection and Cleaning.
г
Seals Pass Through Air and Optional Modules
г
Inspect for wear, abrasion, and cuts. Replace damaged seals or bushings as needed. Refer to
or
Section 6.2.2—Optional Electrical Module Seal Inspection and Replacement
