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).
