7.2.3.7 Mix
Mixtures with other biodegradable oils are not allowed.
The remaining amount of mineral oil must not exceed 5% of total filling quantity as long as the mineral oil is suitable for the
same use.
7.2.3.8 Micro-filtration
When making the conversion on second-hand machines, always take into account the high dirt dissolution power of
biodegradable oil.
After conversion, the dissolution of fault-causing deposits in the hydraulic system could occur. In extreme cases, washing the
seal housings can cause greater leaks.
To prevent faults as well as avoid any negative effect on oil quality, after the conversion, it is best to filter the hydraulic system
using a micro-filtration system.
7.2.3.9 Disposal
The biodegradable oil, inasmuch as saturated ester, is suitable for both thermal and material re-use.
It therefore provides the same disposal / re-use options as mineral based old oil.
Such oil can be incinerated whenever local laws allow.
Recycling the oil is preferable to disposal on dumps or incineration.
7.2.3.10 Topping up
The oil must
ONLY EVER be topped up with the same product.
Note: Max water contamination is 0.1%.
During oil change or topping up, do not discard the hydraulic oil in the environment.
