Important information for the use of biodegradable oil
• Use only the biodegradable hydraulic fluids which have been tested and approved by
Wacker Neuson GmbH. Always contact Wacker Neuson GmbH for the use of other
products which have not been recommended. In addition, ask the oil supplier for a
written declaration of guarantee. This guarantee is applicable to damage occurring on
the hydraulic components, which can be proved to be due to the hydraulic fluid
• Use only biodegradable oil of the same type for filling up. In order to avoid misunder-
standings, a label providing clear information is located on the hydraulic oil tank (next to
the filler inlet) 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 initial hydraulic fluid in the
hydraulic system does not exceed 8 % when changing biodegradable oil (manufacturer
indications)
• Do not fill up with mineral oil – the content of mineral oil should not exceed 2 % 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
Maintenance plan DT08-P (petrol engine)
Maintenance plan DT08-D (diesel engine)
• Always have the condensation water in the hydraulic oil tank drained by an authorised
workshop 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
• If additional hydraulic attachments are mounted or operated, use the same type of
biodegradable oil for these attachments to avoid mixtures in the hydraulic system
Subsequent change from mineral oil to biodegradable oil must be carried out by an author-
ised workshop or by your Wacker Neuson partner
