DISPOSAL OF HYDRAULIC FLUID
Hydraulic fluids have special waste disposal rules: disposal of hydraulic fluid into the environment is prohibited by law,
thus disposal must adhere to manufacturer indications and laws concerning this subject.
CHOICE OF HYDRAULIC FLUID
Any mineral based hydraulic fluid is suitable for use. When choosing a hydraulic fluid, it is necessary to keep in mind
optimum temperature/viscosity when the system is functioning, operating data and the temperature of the environment.
Specific synthetic or glycol water oils may be used if authorised by the technical department but their use must be
evaluated each time.
WARNING! CHANGE THE OIL AFTER THE FIRST 100 HOURS OF SERVICE OR AFTER THE FIRST
1000 OPERATING CYCLES AND THEN EVERY 3000 HOURS
CLEAN THE PUMP SUCTION FILTER (OR, IF NECESSARY, DISCHARGE FILTER) AT THE SAME TIME AS
THE OIL IS CHANGED AND, IF NECESSARY, REPLACE IT WITH A NEW ONE.

DISPOSAL OF HYDRAULIC POWER PACK
The hydraulic power pack is made up mainly of aluminium alloy, steel alloy and plastic. These materials can be
disposed of as with any normal metal or plastic after careful emptying of the hydraulic fluid (to be disposed of
according to law) from the various components such as: pumps, tanks, tubes, filters, valves, etc...
