Maintenance and care

WARNING
Unexpected movement of components.
Injury due to impacts or pinching.
• When working on the axis, switch off the controller and secure it to prevent it from
being switched back on unintentionally.
• For ELGA-TB-...-P0: Check the cavity between the guide and toothed belt for foreign objects and
remove these if present.
• Clean the axis as required with a soft cloth. Do not use aggressive cleaning agents.
Checking toothed belt with ELGA-...-F1
WARNING
Uncontrolled payload if the toothed belt breaks.
Injury due to impacts or pinching.
• Check the toothed belt for wear (e.g. toothed-belt friction) after 1000 km of operat­
ing distance and then after every 500 km of operating distance.
• If there are signs of toothed belt wear, send the axis to Festo or contact Festo service
(è 8 Disassembly and repair).
Note
Retensioning shortens the service life of the toothed belt.
• Do not retension toothed belt.
Checking cover band
• Check the cover band after every 2000 km of operating distance.
Waves on the cover band are a sign for wear of the band reverser.
• Whenever waves form, retighten cover band on both sides:
1. Unfasten threaded dowels (è Fig. 16).
2. Push the cover band into the cover. The cover band must not make contact with the inside top
surface of the carriage.
3. Tighten cover band with a tensioning element 5 (è Fig. 16).
4. Tighten down the threaded dowels (tightening torque: 2 Nm).
If the cover band can no longer be retensioned:
• Replace band reversal points and cover band (è www.festo.com/spareparts).
