Inspecting and Cleaning the Gripper

The gripper must be inspected and maintained regularly in order to ensure that it works optimally. For
instructions on how to do so, see Section 8.1 General Maintenance Instructions.

Switch the compressed air, electricity and vacuum generator off in ad-
vance.

1. Check the cable and hose connections. Check for damaged areas, leak-

age, ensure that the screw unions are tight and that no screws are missing,
etc.

2. Check that the attachment parts such as the housing cover, cylinder mount-

ing plate and quick-release clamp are secured correctly. Check that the
quick-release clamps are securely attached, intact, and easy to operate.

3. Open the quick-release clamp and remove the quick-change plate. The

suspension device must be clean. For information on inspecting and re-
placing the sealing plate if necessary, see Section 8.8. The quick-change
section can be blown off with compressed air as a single component (with-
out the sealing plate) or cleaned with the cleaning agent described above.
