VALVOLINE
It is not possible to mix the synthetic biodegradable oil type HEES with ordinary hydraulic oils, since
q
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).
Biodegradable oil can be used only in the hydraulic system; it cannot be used for the engine, the
q
transmission, the braking system, etc.
Before introducing biodegradable oil in the hydraulic system, empty the system completely,
q
disconnecting the cylinders and all the parts that may contain conventional 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 "4.8.6.a CHECKING THE HYDRAULIC OIL LEVEL").
