Maintenance:
Extensive maintenance work only becomes necessary at fairly long intervals (approx. every 5 million
gripping cycles). As soon as the gripper starts to bind and lose its gripping force, however, it must be
removed from the machine and subjected to a general cleaning.
The gripper is thereby dismantled into its individual parts, inspected for wear, cleaned and after repairing
any damaged parts reassembled and recoated with special grease. We recommend that the sealing
elements subjected to dynamic loads, in particular, are replaced at this point. One set of the wear parts
and sealing elements marked in the parts list should therefore always be in stock for this purpose.
During assembly of the gripper, pay careful attention that marked parts are installed in their correct
positions again.
We should point out that only OEM spare parts or installation parts from authorised suppliers should be
used. No warranty claims will be accepted for any damaged caused by the use of parts from third parties.
Note: For smooth ordering of spare parts or individual parts, always
quote the 6-digit identification number engraved on the
component and – if possible – also the serial number. The serial
number consists of a letter followed by 2 number and possibly a
consecutive number stamped either on the rating plate or in the
immediate vicinity of the identification number.
