Troubleshooting - UDOR VY Series Use And Maintenance Manual

Use OIL type CLP 220 or an alternative Gear Oil type SAE 85W-90. Here are some recommended types of oil:
The oil is to be changed by draining it through the dedicated bottom discharge cap and strictly with the Pump
stopped.
Every time you unscrew the oil drain plug we suggest to replace its gasket.
DO NOT START THE PUMP IF THERE IS NO OIL IN THE PUMP!
During maintenance, you are recommended to:
- Use and wear suitable personal protection equipment (i.e. gloves).
- Wait for the machine to cool down and to have stopped completely.
During maintenance, do not throw residues outdoors but observe current standards
If the Pump is to be scrapped:
1. Separate the various parts depending on their type (i.e. plastic, harmful fluids, metal etc.).
2. Use public or private waste disposal systems envisaged by local law to dispose of waste.
