Installation considerations

Performance considerations

Recommendation

The internal air line normally used to supply the internally-mounted hand valves (Adept

Option Kit P/N 02853-000) is instead used to provide vacuum to the bellows/outer link. One of the external 6 mm user air lines would need to be used to supply the hand valves instead.

The air exhausting from the internally mounted hand valves may be of sufficient quantity/ quality to cause the robot to fail to meet Class 10 particulate limits.

For these reasons, Adept recommends mounting hand valves externally.

8.5 Maintenance

Bellows Replacement

Check the bellows, Adept p/n 04625-000, periodically for cracks, wear, or damage. Replace bellows, if necessary, using the following procedure:

Removing the Bellows

1. Loosen the lower bellows clamp by loosening the screw and pulling the clamp apart slightly. See the following figure.

Figure 8-3. Lower Bellows Clamp

2. Remove the tool flange. Refer to Removing and Installing the Tool Flange on page 75 for

the tool flange removal procedure.
