Injury due to impact 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-TB-RF-F1
WARNING
Uncontrolled payload if the toothed belt breaks.
Injury due to impact 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 ser­
vice (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.
• In case of wave formation, retighten cover band on both sides:
1. Loosen the screws (è Fig. 16).
2. Push the cover band into the cover.
3. Tighten screws (tightening torque 2 Nm).
If the cover band can no longer be retensioned:
• Replace band reversers (è www.festo.com/spareparts).
