Important information regarding operation with biodegradable hydraulic oil
• Use only the biodegradable oils that have been tested and released by
Wacker Neuson.
• Add only biodegradable oil of the same type. In order to avoid misun-
derstandings, attach a clear label to the hydraulic oil filler neck
providing clear information regarding the type of oil currently used. The
joint use of two different biodegradable oils can affect the quality of one
of the oil types. Therefore ensure that the remaining amount of biode-
gradable oil complies with the national and regional regulations as you
replace it. Observe the manufacturer’s indications.
• Do not add mineral oil – the content of mineral oil should not exceed
2 % of the system fill in order to avoid foaming problems and to ensure
biological degradability.
• When running the machine with biodegradable oil, the same oil and
filter replacement intervals are valid as for mineral oil.
• Always have the condensation water in the hydraulic oil reservoir
drained by a Wacker Neuson service center before the cold season.
The water content may not exceed 0.1 % by weight.
• The instructions in this Operator’s Manual concerning environmental
protection are also valid for the use of biodegradable oil.
• Subsequent change from mineral oil to biodegradable oil may only be
performed by a Wacker Neuson service center.
