LUBRICANTS, FUEL AND COOLANT SPECIFICATIONS 4.4.1 HOMOLOGATED HEES SYNTHETIC BIODEGRADABLE LUBRICANTS 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 : 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 are deposited on the filters and clog them (the maximum concentration of ordinary oil cannot exceed 1% of the total quantity of oil).
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 complete- ly, 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 temperature 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 "3.3.1.2 CHECKS BEFORE STARTING" - " CHECK OIL LEV- EL IN HYDRAULIC TANK, ADD OIL"). 169 SUPPLIER HEES SYNTHETIC BIODEGRADABLE OIL KOMATSU BO 46 G4 (KES 07.872) AGIP — ARAL — AVIA — BP — CONDAT CONDAT D 46 K ELF — ESSO — FINA BIOYIDRAN SE 46 FUCHS — KENDALL — KUWAIT PETROLEUM K8 — MOBIL EAL SYNDRAULIC MOBIL (USA) — PAKELO — PANOLIN HLP SYNTH 46 SHELL NATURELLE HFX-32 TAMOIL — TEXACO — TOTAL HYDROBIO 46 VALVOLINE — CAUTION
