4.3.2 HOMOLOGATED SYNTHETIC BIODEGRADABLE LUBRICANTS
“HEES”
Komatsu machines can be filled with synthetic biodegradable hydraulic oil type HEES not of plant origin and there-
fore 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 are deposited 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 trans-
mission, the braking system, etc.
q
Before introducing biodegradable oil in the hydraulic system, empty the system completely, disconnect-
ing the cylinders and all the parts that may contain conventional oil, and replace the drain filter with a
new one.
q
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.
q
Stop the engine and check the oil level (see "4.8.6.a CHECKING THE HYDRAULIC OIL LEVEL").
