Important information for the use of biodegradable oil
• Use only the biodegradable hydraulic fluids which have been tested and approved by
Wacker Neuson. 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
misunderstandings, 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 severely affect the quality of one of
the oil types. Therefore when using a different kind of biodegradable oil, ensure that the
remaining amount of initial biodegradable oil does not exceed the indications of the
manufacturer of biodegradable oil.
• 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 – see chapter 3.3 Maintenance plan (overview) on
page 3-7.
• 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 service 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 a Wacker
Neuson workshop or your Wacker Neuson dealer.
