This SICK sensor is maintenance-free.
We do, however, recommend that the following activities are undertaken regularly:
•
Clean the optical interfaces using a plastic cleaner, do not use acetone or methy‐
lated spirits.
•
Check the fittings and plug connectors
No modifications may be made to devices.
