Technical precautions for proper maintenance
For proper maintenance:
- use only original spare parts and appropriate, well-kept tools;
- respect the time periods between programmed maintenance operations (preventive and periodic)
indicated in the manual;
- the time periods indicated (in time or in work cycles) between one operation and the next are
intended as the maximum acceptable; these time periods should not be exceeded; they may,
however, be reduced;
- proper preventive maintenance requires constant attention and continual observation of the machine.
Immediately identify the cause of any eventual anomaly, such as excessive noise, overheating, fluid
leakage, etc., and take the appropriate measures to resolve it.
If in doubt, contact the manufacturer or an authorized assistance centre.
