Important notices on the use of biodegradable oil
• Use only the biodegradable hydraulic fluids which have been tested and approved by
Wacker Neuson. Always contact Wacker Neuson for the use of other products that
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 that can be proved to be due to the hydraulic fluid.
• Use only biodegradable oil of the same type for adding oil. In order to avoid misunder-
standings, a label providing clear information is located on the hydraulic oil reservoir
(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 add mineral oil – the content of mineral oil should not exceed 2 % by weight 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 5.18 Maintenance plan (overview)
on page 5-38.
• 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.
• If additional hydraulic attachments are installed 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 performed by a Wacker
Neuson service center or your Wacker Neuson dealer.
