Hi Oye,

Changing lubricant based is not easy. and i hope you get success on it.
I am advising you to consider the following factor:
- Sellect the biodegradable lubricant which having fire resistant properties, if you need so
- Sellect the biodegradable lubricant which having less effect to build varnish / sludge.
- Check the compatibility of all elastomer material in your hydraulic system. Ensure that all are compatible with the new biodegradable lubricant which you sellect
- Flush your system completely to avoid lubricant incompatiblity , and ensure the flushing oil is drained out properly.
- Do regular check / oil analysis ( freq: 3 - 6 months)
