APPROVED SYNTHETIC BIODEGRADABLE LUBRICANTS TYPE HEES 4
Our machines can be filled with synthetic biodegradable hydraulic oil type HEES not of plant origin and therefore
the use of the oils indicated in the following table is authorized and recommended:
CAUTION
q
It is not possible to mix the synthetic biodegradable oil type HEES with ordinary hydraulic oils, since
when the temperature increases insoluble compounds are generated, which deposit on the filters and
clog them (the maximum concentration of ordinary oil must not exceed 1% of the total quantity of oil).
q
Biodegradable oil can be used only in the hydraulic system; it cannot be used for the engine, the
transmissions, the braking system, etc.
q
Before introducing biodegradable oil in the hydraulic system, drain the system completely,
disconnecting the cylinders and all the parts that may contain traditional oil, then change the drain
filter with a new one. Start the engine and let it idle before using the equipment, wait for the engine
temperature to reach at least 40°C, then start moving the equipment to fill all the circuits with oil. Stop
the engine and check the oil level (see "Check the oil level in the hydraulic tank and top up (3-116)").
