NOTICE

Damage due to improper maintenance!

The hexapod can become misaligned as a result of improper maintenance. The
specifications can change as a result (p. 59).



Only loosen screws according to the instructions in this manual.

Depending on the operational conditions and the period of use of the hexapod, the
following maintenance measures are required.

7.1 Performing a Maintenance Run

Frequent motions over a limited travel range can cause the lubricant to be unevenly
distributed on the drive screw.



Perform a maintenance run over the entire travel range at regular intervals

(see documentation of the hexapod controller). The more often motion is
performed over a limited travel range, the shorter the time has to be
between the maintenance runs.
