7.2.3.1 Biodegradable hydraulic oil (Optional)
At the request of the customer, the machines can be supplied with biodegradable hydraulic oil compatible with the environment.
Biodegradable hydraulic oil is completely synthetic, without zinc, non-polluting and highly efficient with saturated ester base,
combined with special additives. The machines with biodegradable oil use the same component parts as standard machines,
but the use of such type of oil is best taken into account from machine construction.
In case of wanting to change from mineral-
oil based hydraulic oil to “bio” oil, the following procedure mu st be followed.
7.2.3.2 Emptying
Empty the hot hydraulic oil for entire system operation (oil tank, cylinders, large-volume pipes).
7.2.3.3 Filters
Change the filtering inserts. Use standard filters as indicated by the manufacturer.
7.2.3.4 Washing
After completely emptying the machine, fill the recommended type and quantity of “bio” oil.
Start the machine and perform all work movements at low revs for at least 30 minutes.
Drain the liquid from the system as indicated at 7.2.3.2.
Warning: During the entire washing procedure, avoid air entering the system.
7.2.3.5 Filling
After washing, fill the hydraulic circuit, bleed and check the level.
Bear in mind that contact of fluid with the hydraulic pipes can cause swelling.
Also remember that contact of fluid with the skin can cause reddening or irritation.
Also use suitable PPE during these operations (e.g., protective eyewear and gloves).
7.2.3.6 Commissioning / check
“Bio” oil behaves regularly, but it must be checked by taking a sample at set intervals according to the indications prov ided
below:

The fluid state is therefore constantly monitored, thus allowing its use until its features decay. Normally, in the absence of
contaminating agents, the oil is never completely changed, but only occasionally topped-up.
The oil samples (at least 500ml) must be taken with the system at operating temperature.
It is recommended to use new and clean containers.
The samples must be sent to the “bio” oil supplier. For more dispatch details, contact Your nearest dist ributor.
Copies of the analysis report must be kept in the check register. This is mandatory.
