FUEL, COOLANT AND LUBRICANTS 4.3.1 HOMOLOGATED HEES SYNTHETIC BIODEGRADABLE LUBRICANTS 150 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 :

• The synthetic biodegradable oil can be used only in the hydraulic system; it cannot be used for the en- dothermic motor, the transmissions, the braking system, etc. • Before introducing the synthetic biodegradable oil in the hydraulic system, empty the system com- pletely, disconnecting the cylinders and all the parts that may contain ordinary oil, and replace the drain filter with a new one. Start the engine and let it idle without using the work equipment , wait until the oil reaches a tempera- ture of at least 40°C, then start moving the equipment, so that all the parts of the system are filled with oil.
Stop the engine and check the oil level (see “4.7.3.e CHECKING THE HYDRAULIC SYSTEM OIL LEV- EL”).
